TY - JOUR T1 - Enlarged livers and hepatic microsomal mixed-function oxidase components in tumor-bearing brown bullheads from a chemically contaminated river. AN - 14587966; 1467842 AB - Hepatic mixed-function oxidase (MFO) components in tumor-bearing brown bullheads (Ictalurus nebulosus ) from a chemically contaminated river and in bullheads from two relatively uncontaminated sites were compared to determine if the components in the river bullheads were induced. In general, biochemical hepatic microsomal MFO component levels in bullheads from the river were the same as, or lower than, those in bullheads from uncontaminated sites. However, the liver weight as a percentage of body weight was significantly greater in bullheads from the river than in those from the uncontaminated sites. Biochemical hepatic microsomal components measured in this study were apparently not adequate as indicators of chemical contamination of the river water or of contaminant stress in bullheads from the river.

AN - 14554640; 1437534 AB - Nesting Common Terns (Sterna hirundo ) were studied at a number of barrier beaches and small islands of tidal salt marsh in New Jersey and the Eastern Shore of Maryland-Virginia from 1980 though 1982. Clutch sizes varied among colonies and across years but no systematic effect of year, habitat, or colony size on mean clutch size per colony was detected. Analyses of nest productivity failed to reveal significant effects of habitat or colony size but showed a strong year effect. Nest spacing in salt marsh colonies was much closer than it was on barrier beaches. In mixed-species colonies with Black Skimmers (Rynchops niger ), distances between tern and skimmer nests were also much smaller in marsh colonies than they were on beaches. Several lines of evidence suggest that terns prefer beaches to marshes for nesting; however, the uncertainty of predation and flooding may often obscure any intrinsic differences in habitat quality.

AN - 14490427; 1397033 AB - Abraham et al. (1983) demonstrated that positive assortative mating by necklace type, the white feather pattern around the neck, occurs among Brant (Branta bernicla hrota ) breeding at East Bay, Southampton Island, N.W.T. They also suggested that differential distribution of Brant by necklace type also may occur on the wintering grounds. The authors tested the "differential distribution" hypothesis by collecting Brant on three major wintering areas along the Atlantic Coast: 1) Nassau County, Long Island, New York; 2) Cape May County, New Jersey; and 3) Chincoteague National Wildlife Refuge and near Folley Creek, Accomac County, Virginia. Brant were shot in bays and estuaries in the three locations, except for 18 birds that were cannon-netted on golf courses on Long Island. Collections were made during a 2-week period in late January 1984 so that Brant movements among the three locations were minimal. JF - Auk AU - Vangilder, L D AU - Smith, L M AD - Patuxent Wildl.

AN - 14473793; 1379653 AB - Conversion of bottomland hardwood forests to agricultural land has reduced habitat and water quality in many lakes in the floodplain of the lower Mississippi River. The objectives of this study were to ascertain current contaminant residue concentrations in fish and sediment from lakes in the Atchafalaya River basin and to determine the influence of overflow and agricultural land use on contaminant levels. Residue analysis of 24 sediment and 82 fish samples collected from the study lakes showed that contaminant residues were uniformly low. Total DDT concentrations, consisting mainly of DDE, were found in 98% of the fish samples and generally were the highest residues though they rarely exceeded 0.50 mu g/g. Dieldrin, alpha -BHC and gamma -BHC, in concentrations rarely exceeding 0.05 mu g/g, were detected in about 50% of the fish samples. Total organochlorine pesticide and PCB residues were less than 2.00 mu g/g in all fish from all lakes, except for 3.46 mu g/g total in spotted gar (Lepisosteus oculatus ) from one lake.

Both DDE and PCB's declined significantly during a 10-day interval. The present study was undertaken to verify and quantify this decline for the entire incubation period. Eggs were analyzed for DCBP (4,4'-dichlorobenzophenone) because it is a breakdown product that is likely to be present if DDE was metabolized. The data collected also allowed the authors to measure changes in egg weight, embryo size, and weight of eggshell that occurred during incubation.

AN - 14385334; 1247188 AB - Ninety-two West Indian manatees (Trichechus manatus ) have been captured in the southeastern United States from October 1975 through November 1983 with no evidence of an unusual susceptibility to capture myopathy. Of these, 53 were radio-tracked or observed in the field following capture with no evidence of delayed caputure stress. Blood samples obtained at capture for 20 wild individuals displayed no elevation in biochemical variables typically seen in mammalian capture myopathy cases. Thirty-one manatees captured for rescue and rehabilitation generally did not exhibit symptoms of capture myopathy, although in one case marked elevations in creatinine phosphokinase were observed, probably related to lengthy transport. Necropsy findings for 20 terminal cases that died of various causes unrelated to their rescue or handling did not indicate the involvement of any gross or histological lesions of capture myopathy.

Selected temperatures and ration were directly and linearly correlated: the larger the ration, the higher the temperature selected. Mean preferred temperatures at different rations (shown in parenthese as percent of body weight per day) were as follows: 9.2 degree C (0.3); 10.6 degree C (0.8); 11.7 degree C (2.0); and 12.6 degree C (5.5).

Part 2. Field assessment and data evaluation. AN - 14259416; 1101692 AB - This study shows that biological assessments of water quality status using biomass estimates of wet, dry, and ash-free dry weights and counts of individual organisms from a small, headwater stream in southwestern Ohio provide essentially similar results concerning the impact of a sewage treatment plant discharge. Of the indices of biotic status for the stream segment employed for data evaluation; Diversity Index (D), Community Diversity Index (d super(-)), Trophic Condition Index (TCI), and Empirical Biotic Index (EBI), the latter two provided evaluations most consistent with benchmark water chemistry and physics information concerning the trophic status of the stream. In addition, the percent composition of macro-invertebrate taxa by pollutional category; "clean water", "facultative", and "pollution tolerant", as ascribed using TCI and EBI ranges for individual taxa collected in combination of Ekman grab, rock-filled basket sampler and drift net samples, proves adequate for interpretation of biotic status.

AN - 14168461; 977525 AB - Foraging behaviors of wintering gadwall (Anas strepera ), pintail (Anas acuta ), and green-winged teal (Anas crecca carolinensis ) were studied at Bodie Island, North Carolina. Foraging speed (metres per minute) and rate of foraging (dips per minute) did not differ by sex, but significant monthly variation of foraging components occurred for all species. Ducks fed at faster rates and increased their foraging speed as winter progressed. Changes in the foraging speed and rate of dipping of winter ducks were significantly related to decreases in day length and average daily temperatures. Other environmental parameters had variable effects on foraging behavior. Estimates of total prey biomass did not vary significantly during winter, however, changes in the distribution of prey sizes may have contributed to changes in foraging behavior. Greater foraging speed and rate of dipping may have been a behavioral mechanism which increased ingestion rate and minimized foraging time, thereby allowing wintering ducks to reduce thermal stress through modification of activity patterns and selection of more favorable microclimates.

AN - 14162969; 979031 AB - Fluctuating asymmetry, the random deviation from perfect bilateral symmetry owing to developmental perturbation, has been used in a number of studies to quantify stress during early life. A link between environmental acidification and fluctuating asymmetry was postulated. Brook trout (Salvelinus fontinalis ), white sucker (Catostomus commersoni ), and lake chub (Couesius plumbeus ) were collected from lakes over a wide range of pH values. Most characters examined were not significantly more asymmetric in acidified lakes. However, one or two characters in each species were more asymmetric in lakes of lower pH. Relative overall asymmetry in brook trout was related to parameters that changed with acidification. The results are consistent with the hypothetical link between environmental stress by acidification and increased fluctuating asymmetry, but the connection is much weaker than expected. This finding, the need for large sample sizes, and the lack of a definite causal link, severely limits the utility of this type of analysis in assessing the level of stress in fish populations.

AN - 14122479; 942818 AB - Laboratory studies were conducted to determine the acute or chronic toxicity of seven potential polychlorinated biphenyl (PCB) replacement products to the alga Selenastrum capricornutum and three species of invertebrates. Significant reductions in algal biomass after 14 d of incubation were measured in tests with five phosphate esters at nominal concentrations ranging from 0.10 to 10 mg/L. The acute toxicity of six phosphate esters tested against a daphnid (Daphnia magna ), a midge (Chironomus plumosus )and an amphipod (Gammarus pseudolimnaeus ) was moderate, ranging from 1.1 to 18.0 mg/L. Chronic toxicity tests based on nominal concentrations indicated that five of the six phosphate esters tested against daphnids reduced survival and reproduction at concentrations ranging from 10 to 56 mu g/L, whereas only one of three tested against amphipods significantly reduced growth and survival at concentrations of 31 to 128 mu g/L.

High temephos-related mortality occurred in the 100 ppm group in the unheated brooder but not in any other diet-temperature groups. Ingestion of the 100 ppm temephos diet inhibited plasma cholinesterase (ChE) activity and elevated plasma corticosterone concentration and creatine phosphokinase activity, but other selected plasma chemistries were not affected in a dose-related manner.

AN - 14105072; 924952 AB - A major breeding colony of northern elephant seals (Mirounga angustirostris ) occurs on San Nicolas Island, California. Due to commercial hunting, elephant seals were extinct on San Nicolas Island by the end of the 19th century. Subsequent recovery of the population has been well documented. Census data collected since 1949 indicate that the colony has been growing rapidly in numbers after breeding began again in the late 1940's. In summary, the colony of northern elephant seals on San Nicolas Island continues to grow exponentially. In recent years, pup production has increased most rapidly at the west end of the breeding area. Although the length of the breeding area has approximately tripled since 1971, many beaches which appear suitable for pupping remain unused. The authors feel that population growth should continue and that expansion of breeding areas will also continue as current breeding beaches become saturated.

Theoretical derivations are made to determine the relationship between gravel concentration and unit stream power. Laboratory data are used to verify the assumptions used as well as the accuracy of some of the well-known transport equations. The assumption that bed load or gravel concentration can be determined by either shear stress or stream power is questionable. Based on the data shown there is a strong one-to-one correlation between unit stream power and bed load or gravel concentration. The reason that sediment concentration should be related to unit stream power can be derived from general physics as well as from basic theories in fluid mechanics and turbulence. Among the four equations compared, the dimensionless unit stream power equation for gravel transport is more accurate than others for the gravel data used in this paper.

Control for estimating the ages of faulting events is provided by soil stratigraphy, C-14 ages on organic sediments, and the Mazama ash (7000-6700 yr), which is present at both sites. The first site displayed evidence of at least three, probably four, and possibly five displacements within the past 7500 yr. Evidence of at least three and probably four post-Mazama-ash faulting events was found at the second trench site. The juxtaposition of lithologically contrasting deposits and units with different thicknesses on opposite sides of the faults indicates strike-slip faulting. The estimated average recurrence of surface faulting events (Ms 6.5) is about 1800 yr assuming four post-Mazama-ash events and about 2400 yr for three events. The most recent event occurred within the past few hundred years. The rate of recurrence of surface faulting events on the Pyramid Lake fault zone is three to five times higher than for most faults in the western Basin and Range province.

The sparse distribution of weather stations typical of the intermountain rangeland area does not allow site specific analysis of localized precipitation. Crop year precipitation data for seven permanent recording stations in Malheur County, Oregon were analyzed for the 13 year period 1966-78. Elevation above sea level for each station was compared to precipitation received during the crop year through linear regression analysis. Analysis of precipitation amounts occurring on the arid sagebrush steppe revealed significant correlation with elevation. The method can be used to yield precipitation data for use in the determination of vegetation production.

Methods for restoration of these drains such as mechanical routing and sulfur dioxide gas treatment are expensive and dangerous. A technique was developed for cleaning drains in which the drains are flooded with a 10% sulfamic acid-sodium chloride solution. The present method costs less than a fifth of the replacement cost. The cost of treating a severely plugged 240-mm drainage pipe would range between $3 and $6 per meter. Sulfamic acid is not considered to be a hazardous material when neutralized before disposal, and is available in granular form, making it safe to transport and use. The ease of use and lower costs of the sulfamic acid-sodium chloride method should make this method an attractive option for drainage systems of projects of the Bureau of Reclamation.

Four prehistoric sites and three historic sites were recorded during the survey. Manifestations of cultural behavior resulting from a lifeway of prehistoric, seasonal resource exploitation are contrasted to the manifestation resulting from a historic sedentary adaptation. The presence of a possible Rose Spring Corner Notched projectile point indicates human utilization of the North Fork drainage from at least 300 A.D. to the present. Five sites are recommended for avoidance or mitigation. The possible presence of subsurface deposits at these sites suggests eligibility to the National Register of Historic Places.

A two-phase strategy for such demonstration projects involves nominating, selecting, and planning recharge demonstration projects which the Secretary of the Interior will then submit to Congress (Phase I), and then constructing those projects recommended by the Secretary and approved by Congress (Phase II). The federal share of the program 's funding for Phase I activities is currently set at $500,000 and for Phase II at $20 million. Both the Bureau of Reclamation and the Geological Survey will be available to help non-federal entities as they draw up their proposals. Water diversion projects are suggested as one possible long-term solution to the problems of groundwater depletion in the High Plains area. Recent court decisions have indicated that water is an article of interstate trade protected from state intervention. However, Congress introduced bills in 1983 that sought to reverse that interpretation. Groundwater withdrawals have translated into potential losses that could affect not only farmers, but all U.S. consumers who rely on farm products.

HIPLEX involved a number of field projects as well as supporting studies in short-range forecasting, cloud modeling, forage and crop yields, agricultural economics, and environmental matters. A randomized experiment (HIPLEX-1) was conducted on isolated cumulus congestus clouds around Miles City 1979-1980 to document the steps in a physical hypotheses linking dry ice seeding of small to moderate sized cumulus clouds to increased rainfall at cloud base. Results showed that liquid water concentrations decreased so rapidly in test clouds that graupel could not grow to precipitation size. It is recommended that seeding trials proceed in larger clouds. Studies of the value of additional precipitation from cloud seeding projects suggest that the net benefits of the HIPLEX project justify continued experimentation to develop an effective precipitation enhancement technology.

The life history characteristics of three fish species, water quality aspects of CAP source and receiving waters, the existing fisheries of CAP sources and receiving waters, physical features of pumping plants, and some life history phenomena of the southern bald eagle are documented. Striped bass and blue tilapia may have an adverse impact on the existing fishery of Lake Pleasant. These two species and the white bass are suspected of having an adverse impact on the ecology of the Salt and Verde Rivers. If blue tilapia enter Lake Pleasant, they will likely survive and reproduce while striped bass will be much less likely to reproduce. Recruitment by introduction would continue to occur. If these fish become established and their numbers are not controlled by predators or environmental pressures, they could have an impact on the fish food base of the southern bald eagles along these rivers.

The essence of the approach employed was the relation by regression methods of simultaneously acquired water quality measurements and digital imagery values. Application of the regression equations to entire scenes achieved a spatial extrapolation of the point measurements of water quality. Secchi transparency and chlorophyll a concentration were the water quality variables modeled with greatest success. Both Landsat and airborne multispectral scanner data were employed. In addition, an atmospheric correction was made to account for date-to-date variations in Landsat imagery. This made possible the development of water quality predictive regression equations using data from several dates at once. It also permitted the estimation of reservoir conditions for scenes without concurrent surface sampling data available.

Beauv AN - 18963318; 8503218 AB - A study of the effects of sodium chloride on one of the prominent bryophytes of the Pinhook Bog in Indiana Dunes National Lakeshore was initiated in response to documented impacts of deicing salt runoff from a salt storage area along the Indiana Toll Road on the vegetation of the bog. Salt concentrations between 300 and 1500 mg/l as Cl significantly reduced growth in length of Sphagnum recurvum in lab cultures. Growth in biomass was also reduced at higher concentrations under certain treatment conditions. Chloride appeared to be a stronger growth inhibitor than sodium. When water content was reduced and evaporational plant surfaces increased, salt was deposited on plant tips through the evapotranspiration process, causing plant mortality at all sodium chloride concentrations tested. Salt encrustations were removed by washing the plants in simulated rainfall occurrences, but the deposits developed quickly again and produced similar lethal effects within 3 weeks after the last wash treatment. Since growth reduction and mortality of S. recurvum were shown at NaCl concentrations observed in Pinhook Bog, it is likely that deicing salts were responsible for the elimination of Sphagnum from the impacted area.

The study consisted of measuring pressures and computing impact factors for loaded construction equipment (scrapers) crossing a buried, instrumented concrete slab. Impact factors were determined experimentally under several conditions which could occur during construction operations. The two factors found to be most significant to computed impact factors were roughness of the ground surface and scraper speed. Factors found to have little influence on the computed impact factors were depth of soil covering the concrete slab and soil type. As expected, the measured pressure increased as the depth of cover decreased. Computed impact factors ranged from 1 to 3. The study results also imply that under certain conditions impact factors larger than 3 are possible. The measurement of large impact factors, under conditions not uncommon to construction sites, dictates that controls be placed on design and construction practices for structures buried near the ground surface.

To this end, two popular streamflow transport simulation models, QUAL-II and WQRRS, were calibrated and verified using data on the Yakima River Basin in south-central Washington. Data were collected in four synoptic surveys during low-flow periods between August 1981 and November 1982. Both models gave similar results compared to observed target parameters values. Simulation of temperature, dissolved oxygen, and nitrate was reasonably accurate. Results for biochemical oxygen demand, ammonia, orthophosphate, and chlorophyll a were not as good, to some extent due to inadequacies in the data set. The validated models and calibrated data sets are available for use in evaluating water quality impacts of water resources development in the Yakima Basin. On the basis of ease of application use of QUAL-II is recommended. (Author 's abstract) JF - Available from the National Technical Information Service, Springfield VA 22161, PB85-172625.

The oxidation involves hydrogen peroxide and an iron (ferric chloride) catalyst and was initially tested in a bench-scale adiabatic reactor to develop operating curves for several concentrations of formaldehyde and to show the total oxidation time as a function of solution temperature, reactant concentration, stirring rate, and the type of purge gas used. A subsequent series of tests generated isothermal data for fitting a temperature and concentration-dependent rate equation. The reaction, which proceeds by formic acid production, was shown to be effective in completely oxidizing formaldehyde solutions at concentrations at, or greater than 250 mg/L to carbon dioxide and water (with formaldehyde vapor detected in the products gas stream at <0.4 mg/cu m). The oxidation was rate-dependent rather than diffusion controlled, and based on chemical similitude considerations, can be scaled up directly. Based on study results, recommendations are made for the design and operation of a full-scale reactor for the Yuma Desalting Plant. An estimate is provided for the cost of chemicals used in oxidizing a single flushing from a control block (45,000 liter) at an assumed concentration of 1200 mg/l.

As a result, the allowable foundation bearing pressure used for design are selected conservatively. This leads to the construction of shallow spread foundations that may be larger and more costly than necessary. To address this situation, the Bureau conducted a research program to evaluate the state of the art as it pertains to predicting the ultimate bearing capacity of shallow spread foundations located on or near slopes. This study consisted of developing and testing a technique for centrifugal modeling of shallow spread footings located on or near slopes; experimentally determining the maximum bearing pressure of four prototype shallow spread footings using scaled models; and comparing test results with state-of-the-art analytical solutions. Test equipment was fabricated to permit model footings to be loaded and their response to be measured at accelerations 100 times that of gravity. The model test results were compared with the results of theoretical solutions obtained using limit analysis, limit equilibrium analyses, a semiempirical method, and methods incorporating slip-line solutions.

In field tests at the LVS site, a 30-liter/min-capacity ion exchange pilot plant softened the feed water to (and thus prevented gypsum scaling in) an electrodialyzer at desalting recoveries of up to 92%. Special techniques were needed to prevent gypsum-scale accumulation in the ion exchange system: (1) the use of recycled regenerant preceding fresh reject-brine regenerant to lower the level of calcium sulfate supersaturation, and (2) high regeneration flow rates and a packed resin bed to minimize the residence time of regenerant in the resin bed. Laboratory ion exchange experiments simulating LVS conditions provided data which agree with field test results but extend the number and ranges of the process variables to better characterize the ion exchange process. Results showed the >90% product-water-recovery rates from desalination plants could be attained while minimizing the brine disposal waste stream. It was possible to use saline water as makeup to cooling towers while minimizing the brine disposal volume. Pretreatment costs were reduced compared with lime soda softening.

Infrared radiation proved to be the most convenient and economical heating technique. Electric resistance heating blankets were also fully satisfactory. Circular pattern cracking, which appeared on the surface of all nonprestressed concrete treated with the system, was not corrected with reductions in drying time and temperature. In fact, this pattern was also observed on untreated concrete bridge decks in use for 3-5 years. Chloride intrusion tests on 40 concrete slabs (exposure to 90 days ' ponding with 3% solution) showed very little chloride intrusion in the impregnated slabs compared with the untreated slabs. However, significantly higher chloride concentrations were found below the impregnated zones than in companion unimpregnated concrete. This showed that pattern cracks permit chlorides to penetrate below the zone of impregnation, resulting in greater chloride concentrations. No active reinforcing steel corrosion was attributed to the chloride penetration. Freeze-thaw and abrasion resistance were significantly improved in concrete not exposed to chlorides. The impregnation system should not be used on new uncracked concrete if the pattern shrinkage cracking is a problem. Until further information is obtained, the system should not be used on concrete exposed to chlorides. An appendix containing the most recent surface impregnation construction specifications is included.

The ponds would be used to generate electric power that could be integrated with the Bureau 's power grid or used in combination with thermal energy from the ponds to power commercially available desalination systems to produce freshwater. Results of the economic analysis, which concentrated primarily on the Tularosa Basin site, showed that solar-pond-generated intermediate load power would cost between 62 and 90 mills/kWh and between 52 and 83 mills/kWh for baseload power. This results in benefit-cost ratios of approximately 2.0 and 1.3 for intermediate and baseload, respectively, when compared to similar facilities powered by fossil fuels. The cost savings are even more pronounced when comparing the two (solar versus fossil fuel) as a source of power for conventional distillation and membrane-type desalination systems.

Coal tar enamel, which has good erosion resistance, is used as the standard of comparison. Materials with better erosion resistance than coal-tar enamel are as follows: 17 reinforced plastic mortar liners, concrete, steel, synthetic and natural rubber sheet, polyvinyl chloride, polyethylene, and acrylonitrile butadiene styrene (ABS). Less resistant materials are four of the reinforced plastic mortar liners, three reinforced thermosetting pipe liners, and one vinyl resin liner for asbestos-cement pipe. Sheet rubber liners are the most erosion resistant. All the thermoplastic pipes (polyvinyl chloride, ABS, and polyethylene) are more resistant than coal tar enamel, up to ratios of 10 to 1.

The slip loss recovery system essentially consists of a three-phase rectifier bridge and an inverter bridge. The rectifier converts rotor slip frequency a-c voltage to d.c. The inverter converts the d.c. to a.c. for power feedback into a 60-Hz, a-c system. In this scheme , the motor is able to operate at various speeds with substantially higher efficiency than a conventional, wound-rotor , variable-speed, induction motor with adjustable rotor resistors. The startup problems at Fountain Valley are due to an inadequate SCR (short circuit ratio) at the drive side of the feedback transformer is the predominate factor in determining the SCR to an unacceptably low value. The SCR and percent distortion factors should have been considered in the sizing of the feedback transformer. Neglecting this equipment coordination task resulted in the manufacturer selecting a feedback transformer considerably smaller than actually required for proper operation. An insertion resistor scheme during the initial startup period has proved successful in eliminating the startup problems. Insertion resistor starting eliminates the problem by reducing the SCR requirements of the drive.

They were the first three Bureau embankments to use soil-cement in place of riprap, and have been in service 18-20 years. The soil-cement facings on later Bureau dams are still in excellent condition. The lack of bond between the soil-cement lifts, in combination with severe weather and wave action, appear to be the main factors contributing to the damage. Laboratory tests and field test sections indicate that cement applied between the soil-cement lifts may be a practical solution to prevent damage to the facing when severe weather and wave conditions exist. Another soil-cement test section is planned for a future Bureau dam. The test section will be incorporated into the soil-cement facing where both dry cement and a cement slurry will be used for the surface treatment between soil-cement lifts.

Results of the slope stability analysis showed that at least moderately cohesive soils are required for construction of efficient semicircular sections. Strength comparisons showed that neither the semicircular nor the trapezoidal shape will take large external uplift or lateral loads when the canal is unwatered. The semicircular shape shows better structural resistance against uplift applied along the bottom of the canal lining while the trapezoidal indicates better structural resistance against lateral loads directed toward the canal. The use of precast concrete and cast-in-place concrete has been replaced by zero-slump concrete semicircular canals. The concrete, location of lining joints, excavation, lining and construction equipment are also considered. Design, maintenance and safety considerations are discussed. Semicircular canals offer reductions in material costs, right-of-way required, spans for crossing, evaporation and seepage losses, and canal invert slope. However, the semicircular shape is not suitable for larger canals because the water depths become too great. JF - Available from the National Technical Information Service, Springfield VA 22161.

In this study, shifts were identified using trend analyses and by comparing mean values before and after major reservoir development. Representative monthly solute concentration and streamflow values were computed for 15 major gage stations. For the 12 stations with sufficient data prior to major flow regulation, trends were identified using regression models. Significant decreases were found for magnesium, sodium, and sulfate at nine stations, accounting for an overall reduction of 2 mg/L/yr for the Lake Mead inflow during the months from December to March. After construction of the Colorado River Storage Project reservoirs, the seasonal variability in salinity was reduced at all downstream stations; concentrations generally decreased in May and June, and increased during the August-March season. Few trends were evident after flow regulation. In addition to reservoir construction, several activities of man were hypothesized as causes of identified trends and mean value changes. The major reservoirs, Lakes Powell and Mead, masked the effects of all other activities. No significant trends in load were found for the station below Lake Mead after 1965.

Stewart Mountain Dam is located 41 miles northeast of Phoenix, Arizona. The dam creates a reservoir with a capacity of 70,000 acre-feet. The construction records indicate a concrete mix with a high and wide ranged, water to cement ratio. Good concrete quality control and placement practices by today 's standards were not employed throughout construction. The average compressive strength for all specimens tested was 5.25 lb/sq in, above average for mass concrete of this age. Average splitting tensile strengths seem high, at almost 500 lb/sq in. Specimens tested under rapid loading conditions, both compressive and splitting tensile, showed the concrete to be of consistently good quality. Modulus of elasticity and Poisson 's ratio are normal for mass concrete, averaging 4.0 x 10 to the (6) power lb/sq in and 0.23 respectively. The movement of the dam since 1968 has been less than the potential indicated by laboratory measurements of expansions due to alkali-aggregate reactions. Based upon the continued reaction potential, monitoring of the dam through instrumentation should be continued. The standard method of core extraction and physical properties testing may never show the real problem, if in fact there is one. An alternative may be the use of state-of-the-art in-situ testing.

A new cement was also developed that consists of over 90% fly ash and anhydrous CaS04. The nonportland cement concrete showed very good compressive strengths and good resistance to sulfate. Excellent freeze-thaw durability was obtained using 90% fly ash concretes in which proper air entrainment was achieved. High Ca ashes plus CaS04 can be used to produce low-strength backfill and subbase concrete. The concrete produced from 90% or more fly ash displayed low-surface abrasion resistance possibly due to surface carbonation. The elasticity of fly ash concrete is similar to that of ordinary portland cement. The drying shrinkage of fly ash concrete normally is less than that of ordinary cement concrete.

The Meyer-Peter and Muller, competent bottom velocity, Lane 's tractive force, Shields diagram, Yang incipient motion, and depth to armor and volume computation models are used to calculate degradation limited by armoring. The Schoklitsch, Meyer-Peter and Muller, Shields diagram, Lane 's tractive force and stable slope and volume computation methods are used to describe degradation limited by a stable slope. Recommendation of a specific method for predicting channel degradation or local scour is difficult because of the complexity and variability of the many factors affecting the erosive action of the channel. It is suggested that several methods be tried before selecting the techniques to be used based upon engineering experience. Descriptions of appropriate bed sampling techniques are included to ensure accuracy in the collection of field data used in the analytical equations.

The data were used to compute the volume of sediments that had accumulated in the reservoir since the gates of the dam were closed in 1938. Sonic depth recording equipment interfaced with an automated survey system was used to run the bathymetric survey. Reservoir capacity was computed based on surface areas determined by a width adjustment method. Reservoir capacity is 331,510 acre-feet; it has a surface area of 11,532 acres. Since 1938, sediments accumulated to a volume of 15,226 acre-feet and result in a 4.4% of loss of reservoir capacity.

The method of Sherard and coworkers ( 'currently accepted method') where soil saturation extract cation data are plotted on a percent sodium versus TDS (total dissolved solids in milliequivalents per liter) graph to classify clayey soils as dispersive or nondispersive, is applied to 223 soil samples from six different soil groups. The method exhibited poor overall agreement with physical test results. These data were subsequently evaluated using analysis of variance and discriminant analysis (a multivariate classification technique) which indicated that each soil group exhibits unique classification criteria based on pore-water cation data. It appears that, for most soil groups in this study , pore-water cation data do not provide adequate identification of dispersive and nondispersive clay soils. Reasons for the observed lack of agreement between pore-water data and physical tests are reviewed and suggestions for further research are presented.

These investigations include delineating areas of suspected seepages in embankment dams and helping to define zones of compression and zones of tension in landslide masses. Where SP and seismic refraction surveys were run over the same embankment site, a tentative correlation has been developed between seismic wave velocity, changes in SP and material properties such as porosity, saturation, and permeability. Self-potentials have several very different sources. These include potentials derived from chemical reactions occurring at ore bodies which pierce the water table, potentials from telluric currents, and those from movement of ions in solution. The SPs of interest in geotechnical investigations are called streaming potentials. These potentials, also called electrofiltration potentials, arise when water carries ions through a porous medium, such as soil. Since streaming potentials are intimately related to water movement, measuring these potentials is one means of detecting seepages in natural ground and man-made structures.

Modern agriculture in the arid district is possible only with irrigation, which now based mostly on imported surface water supplemented by local ground water. In predevelopment time some prominent accumulations of soluble salts were observed in unconsolidated alluvium in the central parts of the Valley. Subsurface irrigational drainage runoff accelerated migration of salts from the Valley margins toward the axial zone, and increased the accumulation of salts in the central parts of the Valley. Such increased salinization of alluvial soils and subsoils endangers valuable farmlands. Understanding the sources and the migration of salts is therefore of both practical and theoretical importance. Isotopic studies of sulfur is salts of 21 samples from alluvial soils, ground water, and sulfur bearing minerals from the Valley, Coast Ranges, and Sierra Nevada indicate that (1) salts in the western part of the Valley originated mainly from the weathering of marine Cretaceous rocks in the Coast Ranges, west of Valley; (2) sulfur bearing salts in the eastern part of the Valley were probably derived from sulfide mineralization in the Sierra Nevada; and (3) Holocene uplift of the western margin of the Valley and the Coast Ranges was probably responsible for an acceleration of the eastward migration of salt dissolved in ground water, and creation of the initial accumulation of salts in the central part of the Valley.

It emphasizes building multi-interest citizen coalitions through community involvement in river and stream conservation efforts, discusses both practical steps for citizen action and conservation tools used effectively throughout the country, from land trusts to easements to regulatory strategies. Case studies are included of innovative programs that suggest how concerned citizens, working together, can positively influence the future of their local rivers and waterways through land and water conservation. Chapters focus on the following topics: guidelines for getting started; understanding the issues of water projects, diversion and minimum flow, pollution, shoreline development and recreation; using basic conservation tools; and choosing a strategy for river conservation projects. Appendices give information on National Park Service regional offices, national river conservation organizations, state river program managers, case-study program managers, national wild and scenic rivers, major federal laws and executive orders applicable to river conservation, and measuring the values of river conservation.

The data analysis included a regression of seasonal values. Interpretation of results of such analyses is based on several general observations, including: differences between regulated and unregulated sites are clearly seen; significant mean value differences are easier to identify than temporal trends in monthly data; trends are more easily identified for low flow periods, probably due to smaller variance in discharge data; changes in concentration, load and mass fraction are associated with river discharge; several dependent variables appear for solute changes; and no single dependent variable is clearly preferable for identification of changes or trends.

The Dolores River picks up an estimated 205,000 tons of salt annually as it passes over a salt anticline in Paradox Valley, Colorado. A control plan which has been adopted involves pumping brine from wells paralleling the Dolores River and adjacent to brine inflow areas. The pumping will lower the freshwater-brine interface below the river channel, thus preventing the brine from entering the river. Brine disposal methods have not been selected; however, disposal in large evaporation ponds, or by deep-well injection, appear to be the most attractive alternatives.

To assess the effectiveness of these improvements, a hydrologically-closed basin, known as the Reed Wash study area, has been equipped to monitor surface and groundwater inflows, outflows, and levels. A monitoring program, implemented to establish preconstruction hydrologic conditions and to observe the effects of canal lining and lateral piping on salt loading in the watershed, is discussed. The monitoring program indicates that the water system improvements have been effective in reducing seepage and salt loading from canals and laterals. This area will be monitored for a number of years to verify the effectiveness of the lining program.

Laboratory studies and field observations indicated that some stiffening of the PVC lining has occurred with time. This stiffening or aging was caused by the loss of plasticizer. With aging, there was generally a reduction in elongation, an increase in modulus at 100% elongation, and a decrease in resistance to impact damage at low temperatures. The rate of this aging depended on three factors: (1) the linings with a high plasticizer content aged less, (2) samples obtained from within the water prism aged less than those obtained outside the prism, and (3) samples obtained from areas where the lining had been placed over a fairly smooth subgrade aged less than those installed over a coarser base. This report also presents design criteria, construction procedures, and updated construction and material specifications for PVC linings.

Other functions include power and navigation and could include irrigation. A 200 m high concrete gravity dam, currently being considered, would be located in the lower reach of the famous Three Gorges of the Yangtze River in Hubei and Sichuan Provinces. The reservoir will store about 70 x 10 to the 9th cu m and extend upstream about 780 km. The proposed powerplant would have an installed capacity of 25,000 MW, consisting of twenty-five 1000-MW units. The Three Gorge Project, when constructed, would be the largest water resource project anywhere on earth. Beneficial effects include elimination of flooding along the middle and lower reaches of the Yangtze River, a substantial increase in much needed electric power for south and central China, and creation of a large body of water which could be used for aquaculture. Consideration is also being given to diverting water to the North China Plain, one of the most important agricultural areas of China. Major adverse impacts include relocation of more than 2 million people from the reservoir area; loss of habitat for many kinds of Yangtze River aquatic life, including the unique Chinese sturgeon; and the possibility of reducing nutrient input to the downstream and estuarine fisheries. The possibility of minimizing adverse effects seems high, if the potential environmental impacts are identified and means of mitigation are carried out.

AN - 14312741; 1131595 AB - The rationale for the use of brain acetylcholinesterase inhibition in fish exposed to organophosphate pesticides is presented. Cyprinid fish from pond cultures and native perch from the Rybinsk Reservoir of the upper Volga Cascade were used in this joint effort. The results of exposure to the pesticides Dylox and malathion are described. Backbone collagen and hydroxyproline content studies, demonstrated as sensitive indicators to the pesticide toxaphene, were applied to the Dylox-exposed fish. Unlike toxaphene, Dylox exposure did not involve hydroxyproline. Rather, diminution of collagen formation is probably a function of inhibition of esterases. The effects of chronic exposure are also discussed. It was found that mortality may occur at a total dose, which is significantly less than the minimum lethal concentration.

AN - 14307213; 1131410 AB - Reports of tumors in wild freshwater fish populations have been increasing. The highly industrialized nature of the Great Lakes basin suggests that chemically-induced tumors could occur in Great Lakes fish. Several indices of tumors in these fish are reviewed, including: thyroid hyperplasia, gonadal neoplasm, papillomas, skin tumors, and tumors of the liver. The results of this study show that papillomas in white sucker, gonadal tumors in carp x goldfish hybrids, and hyperplasia in coho salmon are widespread in the Great Lakes. Tumor incidence is proposed as a sensitive indicator of the level of carcinogenic compounds in the environment. JF - Journal of Great Lakes Research AU - Baumann, P C AD - USFWS, Columbia Natl. Fish.

AN - 14302313; 1131915 AB - Submersed macrophytes were surveyed at 595 stations located throughout the St. Clair-Detroit River system between Lakes Huron and Erie, 23 August to 13 October 1978. Eurasian watermilfoil (Myriophyllum spicatum ), first recorded in the system in 1974, became the fourth most common submersed macrophyte in the system by 1978. However, it has not been reported as a widespread nuisance in this system as it has in many other large water bodies in the United States. Observations made during the present study, and interpretation of an aerial photography, suggest that M. Spicatum was a minor nuisance to small boat navigation in portions of the system. Information presented in this study provides a baseline against which future changes in the occurrence of M. spicatum in the St. Clair-Detroit River system can be measured.

AN - 14295414; 1131379 AB - A microbiological assay, based on the Wood and Werkman reaction (i.e., dark reaction carboxylation by heterotrophic bacteria), was developed to assess chemical-induced changes in aquatic heterotrophic bacterial populations in the laboratory and in natural waters. This simple, sensitive, reproducible super(14)C-radiometric assay was used to monitor changes in biosynthetic activity of naturally occurring heterotrophic bacteria stimulated with an organic nutrient and incubated with known or potential aquatic chemical contaminants. Kepone at water concentrations of greater than or equal to 1.0 mg/L significantly inhibited bacterial carboxylation; inhibition tended to follow a linear dose-response. Simazine slightly stimulated bacterial carboxylation ( greater than or equal to 10 mu g/L); di-2-ethylhexyl phthalate, Dylox, and mirex produced no effects ( less than or equal to 10 mg/L).

AN - 14268925; 1101455 AB - Disseminated visceral coccidiosis (DVC) caused by Eimeria spp was first recognized as a disease entity in captive sandhill cranes (Grus canadensis ) and whooping cranes (G. americana ) at the Patuxent Wildlife Research Center, Laurel, Maryland, USA. Because cranes produced at the Center are reintroduced to the wild to augment wild populations, studies involving both experimentally induced and natural infections were initiated to determine the potential or actual occurrence of DVC in wild Gruidae. Nine sandhill cranes dosed orally with eimerian oocysts of wild origin developed lesions characteristic of DVC. Extraintestinal granulomas associated with developing schizonts were found in 6 birds. Similar lesions were observed in wild sandhill cranes throughout parts of midwestern United States, Alaska, and Saskatchewan. These studies revealed the wide geographic distribution and the high frequency of occurrence of DVC in wild cranes.

AN - 14163897; 977696 AB - Rainbow trout (Salmo gairdneri ) with a mean initial weight of 18.8 g (0.041 lb) were fed one of two experimental diets (29.2% protein or 38.5% protein), or the 38.5% protein diet plus 5%, 10%, or 15% sodium bentonite, for 196 days. The addition of sodium bentonite to the 38.5% protein diet reduced weight gain and increased the unit cost of fish produced. Metabolizable energy content of the diet was a primary factor in determining growth rate. As the percent of dietary lipid increased, the percent of fat in fish carcasses increased and the percent of moisture decreased. Kidney tubules from 5 of 10 fish fed the diet with 15% sodium bentonite showed extreme epithelial swelling and dialation along with cytoplasmic degeneration and renal casts apparent in some tubule lumens.

AN - 14121242; 939728 AB - Stress and mortality associated with truck transport of largemouth bass Micropterus salmoides were characterized during and after simulated hauling periods of up to 30 hours at a density of 180 g fish/liter of water. Generally, "transported" fish had significantly elevated concentrations of plasma glucose and cortisosteroids and decreased plasma chloride concentrations and osmolality. Significant mortality was associated with hauls of 24 and 30 hours (38% and 83-92%, respectively). Plasma characteristics returned to near-normal 3-28 days after being hauled; recover time generally was related to length of haul and associated mortality. Stress was reduced significantly and mortality was eliminated when fish were treated for diseases, held 72 hours without food before they were loaded, anesthetized before they were loaded, hauled at a cool temperature in physiological concentrations of salts with an antibiotic and a mild anesthetic, and allowed to recover in the same medium less the anesthetic.

AN - 14102285; 932968 AB - Plasma values of corticosteroids, glucose, chloride, and osmolality were determined in large mouth bass Micropterus salmoides under various environmental conditions. Differences were observed in plasma glucose, chloride, and osmolality values among fish acclimated to 10 degree , 16 degree , and 23 degree C. Abrupt temperature changes caused elevations in plasma corticosteroid and glucose concentrations and reduced plasma chloride and osmolality. Confinement in a net, for up to 48 hours, caused elevated glucose and corticosteroids and reduced chloride and osmolality values. After 48 hours of confinement, fish required up to 14 days to recover normal plasma characters. Generally, short-term exposure to poor water quality (high concentrations of CO sub(2) and NH sub(3), and low concentrations of dissolved oxygen) altered plasma corticosteroids and glucose but had little effect on plasma chloride or osmolality. Net confinement plus poor water quality caused additional stress.

AN - 14002823; 833744 AB - Pairs of replicate water samples were analyzed for BOD using 60-ml and 300-ml incubation bottles to determine if there were significant differences in measurements of ultimate and 5 day BOD, and the specific rate constant, K sub(1), that could be related to bottle size or volume-to-surface area ratio. The use of the smaller 60-ml bottle was studied to determine if more BOD samples could be incubated without increasing incubator space. More frequent sampling of BOD is important in stream surveys because, in general, the BOD test is less precise than other common tests such as the tests for ammonia, nitrite, nitrate, DO, and temperature. This need to collect more samples for the relatively imprecise BOD tests is rarely taken into account. In practice, fewer BOD samples are collected than samples for more precisely measured parameters (2) because the BOD test usually requires more laboratory space and manpower.

AN - 13993046; 827725 AB - Many pellet-reared tiger muskellunge (F sub(1) hybrid of female muskellunge Esox masquinongy) and male northern pike E. lucius ) do not survive stocking in reservoirs dominated by bluegill Lepomis macrochirus prey. Poor survival may occur because few hybrids capture bluegills. In a previous study done in hatchery ponds, only 10% of naive hybrids (those never before exposed to liver prey) captured bluegills during 15 days. In similar ponds, the authors tested the effects of predator experience (using hybrids previously exposed to bluegill prey), vegetative cover, and bluegill density on the number of hybrids capturing prey. Few experienced or naive hybrids captured bluegills at low prey density, regardless of the presence or absence of vegetation. When bluegill density was increased from 1 to 5 prey/m super(2) in ponds or to 40/m super(2) in aquaria, many hybrids captured bluegills. The pond study suggests that most hybrids will not fare well when stocked in lakes where only bluegill forage is present.

AN - 13986483; 826075 AB - The implementation of plans for the population recovery of the endangered California least tern, Sterna antillarum browni , requires the protection and management of nesting areas in California. Successfully used least tern nesting areas are typically near coastal wetlands, lagoons, or embayments and can be characterized by sparse vegetation, light-colored, sandy substrate, and low levels of intrusion by humans, vehicles, feral and domestic mammals, and avian predators. Decoys are used as a nest site management tool to increase the likelihood that the birds will be attracted to, and nest within the relatively small, protected, nesting areas rather than attempting to nest in physically suitable but more vulnerable locations.

Recent field and laboratory investigations suggest that behavioral patterns also may be altered by exposure to low levels of OP insecticides. Parental care was reduced in songbirds that received a sublethal dose of the insecticide dicrotophos and mortality of nestling laughing gulls (Larus atricilla ) may have resulted from lowered nest attentiveness by parents exposed to parathion. The purpose of the present study was to further assess the effects of a sublethal dose of a commonly used OP insecticide on nest-defense behavior and hatching success of laughing gulls.

In all tests the median particle size of riffle sediments was larger than that in transport and as the particle size distribution of sediments in transport became finer the relative coarsness of riffle sediments increased. High levels of sand in transport caused scouring of stable gravel riffles. These results in combination with data from the literature are used to predict effects including reductions in form roughness by increasing sand delivery, and increases in the channel width/depth ratio and slope.

Samples of dredged material taken from the vicinity of the Folsom South Canal near Sacramento in 1971 contained between 0.018 and 37.5 ppm of mercury. Because 1982 testing of these 1971 samples showed some secondary migration of mercury from the inside portions towards their periphery, there was concern about mercury pollution of the local surface water or ground water which could then enter the canal. Details are given of regional geology and gold mining history of the area and of samples taken from surface water and groundwater which showed high mercury contents of 0.013 to 0.3 ppm. It was calculated that this would amount to an unrealistic discharge of 50 tons per year of mercury from the American river. It was concluded that phosphate ions were masking mercury readings which were, in fact, well within EPA drinking water standards.

The inorganic chemistry of four high altitude lakes which appear similar superficially was compared to determine what controls variation between them. Weathering from the different types of parent material caused differing cation concentrations between the lakes by dissimilar concentrations of those cations which are products of primary weathering. There was s significant difference in anion concentrations between members of one pair having the same bedrock geology. This difference is attributed to the presence of a wet sedge meadow above one of the lakes which serves as a biological filter for anions, particularly nitrate and sulfate. Small scale drainage characteristics which can alter regional atmospheric contributions are important contributors to lake chemistry.

The data has provided a close look at the supercooled liquid water content and ice crystal concentration in winter storms. The cellular echo type clouds clearly exhibit the most desirable characteristics of significant liquid water and relatively little ice. The area-wide and banded echo type clouds provide fewer instances of significant supercooled water and have an abundance of ice crystals. Liquid water maxima were found near the freezing level irrespective of percipitation echo type. Convective clouds provided the greatest likelihood of significant supercooled water. The largest water contents were observed at the greatest temperatures, usually zero to minus five degrees C. Such climatological information suggests that a weather modification program should concentrate primarily on the convective clouds in order to enhance snowfall.

The plugging factor measures the amount of microscopic organic and inorganic particulate matter within the size range measured which is suspended in the water. A totally automatic plugging factor monitor (PFM) test assembly was designed by and tested by government engineers. The PFM electronic controller drives the PFM tester to obtain the necessary data for calculating a plugging factor for a sample of water the PFM-SPSBP draws continuous flow samples of test water for 1-(6) reselected sources. The SPSBP flow operation is schematically diagramed. Other PFM-tester unit function and hardware specifications are also included along with engineer drawings of the mechanisms.

Compared to the original YDP design with 70% desalting recovery, additional removal of calcium in the sesalting feed would allow recoveries over 90%. The sole chemical regeneration solution for the IX (ion exchange) process during steady-state operation would be the sodium-rich brine from the desalting equipment. Pilot plant equipment to test this process was operated at the YDTF (Yuma Desalting Test Facility) and consisted of an IX unit and an electrodialyzer to supply reject-brine regenerant for the IX experiments. Because the reject-brine contained major concentrations of sulfate, gypsum scale occurred in the resin bed under certain IX operating conditions. Scaling occurred especially when the water temperatures were about 30 C in the summer. Scaling did not occur with water tempertures of 15 C in the winter. Gypsum scale buildup in the resin bed could be avoided by regeneration with a high upward flow rate causing a fluidized bed. Reuse of regenerant was also beneficial. Multiple regression analysis of the IX data delineated the importance of several control variables in the IX experiments, including regeneration concentration, flow rate, volume, and temperature. The major response variable was the specific calcium resin capacity divided by the IX cycle duration. This number is inversely proportional to the design resin requirement. Results show that the ion exchange high recovery pretreatment process is highly feasible, and that it is technically possible to achieve high recovery in the YDP. Numerous recommendations for a plant design are given and future studies are noted. JF - Available from Engineering and Research Center, Denver CO.

Subsequent testing showed that the fault was located on the line end coil of one of the parallel groups. Examination of the faulty portion of the coil revealed that most of the strand binder material had decomposed into dust; some had disappeared entirely. The failure mode was primarily mechanical, caused by abrasion induced by electrical vibration. Corona testing on coils in other parts of the powerplant showed a number of high readings in three of the four units in the plant. As a result of the testing, plans were made to rewind the generators, starting with the most badly deteriorated units. JF - REC-ERC-84-4 October 1983. 13 p, 12 Fig, 4 Tab, 1 Ref.

Model tests on the existing structure revealed two areas where pressures were consistently negative, and a third area where intermittent roller vortices occurred during submerged spillway flows. A crown flow constriction was placed in each tunnel, downstream of the low pressure areas, in the hydraulic model. The constrictions were designed in conjunction with downstream air venting. The shape and location of these constrictions were changed several times to determine the discharge capacity versus localized upstream pressure recover. Nonsymmetric crown flow constrictions provided sufficient back pressure to raise the consistently low-pressure areas to acceptable levels during the design discharge. Roller vortices occurred due to a 90 deg square-edged flow boundary on each side of the tower structure. Large radius fillets were placed in the 90 deg corners to eliminate the vortex action.

The 4-inch relief valve, supplied by the Grove Valve and Regulator Company, was designed to reduce positive pressure surges in water pipelines by placing it on a pipeline upstream of a quick closing gate valve. During the tests, the gate valve was slammed shut to produce a sharp pressure wave traveling upstream. Performance of the surge reliever valve was determined by measuring the reduction in the pressure wave as it traveled past the valve. Results showed that the Flexflo surge reliever valve is capable of significantly reducing pressure amplitudes of common hydraulic transients. The valve is capable of reacting to overpressure in 8 to 10 milliseconds. Although the valve testing period was of a short duration, the valve proved reliable in all laboratory tests. Complex systems incorporating a relief valve or valves can be mathematically modeled to provide detailed system/valve sizing data. JF - Available from Engineering and Research Center, Denver CO.

This paper uses data collected at the individual level to estimate the impact of air pollution on either work loss or days of restricted activity. The multiple regression analysis used in this study indicates that increases in air pollution are associated with increases in acute morbidity that result in work loss. In addition, the analysis suggests that urban factors, climate, and occupational exposure do not appear to confound the estimated relationship between air pollution and morbidity.

Despite the recent high interest rates and austere fiscal policy, weather modification programs are becoming more attractive because of their high projected benefit-to-cost ratios and comparatively small capital costs. While more conventional water projects are receiving increasing scrutiny and criticism on cost recovery, applied cloud seeding projects offer prompt payback periods even if interest is computed at the current prime rate. Demonstration of operational weather modification techniques, as in the Bureau of Reclamation 's proposed Colorado River Augmentation Demonstration Program, offers a variety of substantial benefits through enhancing the effectiveness of existing water projects. This program to confirm and demonstrate the capability of cloud seeding to increase the flow of the Colorado River is expected to establish a technology with a benefit-to-cost ratio of 7:1 to 10:1. By producing an annual average of 1.6 million acre-ft (MAF) in the Colorado River Basin and 0.5 MAF in adjacent basins, operational weather modification could generate an additional $30 million in additional hydropower, create $41 million benefits in salinity reduction, and $39 million in new water supplies. An integral part of this as well as any other weather modification demonstration program is a continuing economic feasibility assessment to provide updated projections of program viability. This continuing assessment must keep the program objectives focused on the goal of augmented water supplies while continually evaluating the probable environment for the technology being demonstrated. Essentially this feasibility assessment will be a high-level management tool to refocus or even suspend the program should the projected benefits begin to fade in view of new data.

Noting new definitions for storm and basin PMP, Hydrometeorological Report numbers 51 and 52 (HMR 51-52) procedures are applied to the test basins. Traditional storm transposition and maximization assumptions are also considered. Nine critical storms from the Box Butte Dam region are transposed to the test basins and are maximized for moisture charge. Depth-durational aspects of the storms are presented. Comparisons of PMP estimates are made for the test cases using HMR 51-52 and traditional transposition and maximization techniques. Results show most differences in PMP estimates are within the reasonable range of measurable error.

These real-time hydrometeorological data contribute significantly to improved Bureau program operations in weather modification research, wind and solar energy potential site evaluations, and in water resources project operation. The establishment of a Meteorological Surface Observation Network (MESONET), consisting of 128 solar powered DCP 's enables Bureau scientists in weather modification research to more accurately monitor weather developments. The deployment of 22 solar powered DCP 's at sites with high wind energy potential will permit Bureau engineers to assess the feasibility of installing wind turbine generators at selected sites throughout the West. In addition to being fitted with an anemometer, two of the wind monitoring DCP 's are also measuring solar insolation for solar energy potential site evaluations in the Southwest. The Bureau has also installed 66 DCP 's and has plans for an additional 110 DCP 's in a hydromet system in the Pacific Northwest to provide real-time hydrometeorologic data for making operational decisions to maximize benefits of multi-purpose reservoir systems. Real-time hydrometeorologic data are inexpensive and the data are readily available to users in the Bureau and in other agencies, the data can be immediately integrated with a variety of predictive models, and results are obtained far sooner than would be possible with manual data collection techniques. In addition, for Bureau water resources projects, real-time data can provide the basis for making prompt adjustments in the operational requirements and enhance the ability of Bureau officials to monitor and respond to either drought or flood situations.

Results showed that the concrete in the dam is of good quality, with an average compressive strength of 4,500 pounds/sq inch and an average density of 155.4 pounds/cu ft. Petrographic studies showed that the concrete is of satisfactory physical and chemical quality. No evidence of alkali-aggregate reaction, sulfate or chloride attach, or freeze-thaw deterioration was observed in the interior concrete. Direct shear test results, analyzed by linear regression, were comparable to results obtained on other Bureau projects, with the cohesion on sliding friction tests averaging 215.5 pounds/sq inch, and the average angle of friction was 39 degrees. Sliding friction results indicated similar behavior in both unbonded and bonded joints. These results provide necessary data for design modifications required to withstand the redefined maximum inflow design flood and maximum credible earthquake.

This report contains test data through 1 year 's age and is a part of a series of reports on long-time evaluations of strength and elastic properties of concrete in major Bureau of Reclamation dams. The average compressive strengths at 6 months and 1 year were 33.7 and 35.0 MPa (4,890 and 5,080 lb/sq in), respectively, which represent an average strength gain of 3.9 percent. Paralleling the strength increase, the moduli of elasticity also increased slightly from 31.4 to 31.7 GPa (4,550,000 to 4,600,000 lb/sq in). Tensile strengths for jointed and nonjointed cores were comparable at 6 months, but the nonjointed 1-year tensile strengths averaged 40 percent higher. Ratios of tensile to compressive strengths were high, indicating good paste-aggregate bond. Discussions of test results, variations, construction joint bond, and Poisson 's ratio are also included in the report. JF - Report No. GR-81-8 June 1983. 30 p, 9 Fig, 3 Tab, 4 Ref.

Local saline water use, in areas less than 100 mi distant, for energy production looks promising, but cost-effectiveness is very sensitive to specific site conditions. In order to encourage use of saline water vs freshwater, most utilities need regulatory or financial incentives. The use of saline water for coal slurry transport appears to offer significant potential for joint use savings and reduction in the costs of salinity control. Legal issues and concerns raised about procedures for acquiring diversion rights, allocation of waste saline water among state and federal interests, and transfer of saline water across state boundaries are problems which must be addressed by the Basin states. The institutional arrangements for implementing the options lend themselves to a unique partnership between the federal government and industry. Through the federal salinity control effort, the use of desalting plants and lined evaporation ponds for ultimate disposal would require large monetary investments both in up front construction costs and in long term maintenance. If the private sector were to activate some of these alternative uses for saline water there would also be monetary investments needed. A part of the government capital , focused toward a joint venture with energy related industries, could mean decreased monetary investments for both government and industry and each would reap the rewards. A new bill to amend the 1974 Colorado River Salinity Control Act (Public Law 93-320) has been introduced recently which would permit such joint ventures to take place.

Water quality of two main study streams (one unlogged and one formerly logged) was compared and the unlogged stream had generally higher levels of dissolved solids and lower levels of suspended particulates than the logged stream. Stream channel characteristics were compared on four logged and four unlogged streams. The unlogged streams had over four times more (by volume) of woody debris and 10 times more material in debris dams than the logged streams. Only minor differences in substrate composition were observed. Macroinvertebrate samples from the four logged and four unlogged streams showed that the logged streams contained greater numbers of organisms and more taxa. More detailed sampling on the two main study streams showed similar patterns of more individuals and more taxa in the logged stream, as well as differences in the composition of five functional groups. These differences in invertebrate fauna may be due to differences in quantity and quality of leaf litter inputs, although other explanations are also possible.

The most probable sources of recharge to the springs were determined to be influent Virgin River water and precipitation within the springs by hydrologic basin. These recharge sources could account for the total discharge of the springs. The Littlefield Springs have essentially constant discharge 1.84 cms (65 cfs), and quality 2940 mg/L TDS. Tritium analyses of the spring and river water indicate that there are at least two different sources of recharge to the Littlefield Springs - one a minimum of 22 years old and the other younger than 22 years old. Analysis of the influent Virgin River upstream from the springs indicates a 1.42 cms (50 cfs) loss at 2130 mg/L TDS and the same ionic ratio of dissolved constituents as the springs. The travel time of this recharge source is interpreted to be a minimum of 22 years. Local recharge to the springs has been estimated to be 0.31 cms (11 cfs). The presence of local recharge is indicated by pulse train gaging of the springs, and by water quality at a well upstream of the springs and at the first upstream occurrence of the springs. The travel time of this recharge source is interpreted to be less than 22 years. (Author 's abstract) JF - Ground Water Vol. 21, No. 3, p 325-333, May-June, 1983. 7 Fig, 3 Tab, 12 Ref.

The massive eruption of Mount St. Helens on May 18, 1980 propelled an estimated four billion cu yds of what was once the peak 's summit and northern side to the atmosphere and down its slopes. Absolute devastation resulted. To the northwest not a single living tree was found within 15 miles. The topography near and far from the volcano was rearranged by pyroclastic flows, landslides, mudflows and ashfall. A huge landslide filled the North Fork of the Toutle River, in the process damming Spirit Lake. Enormous mudflows passed down both the North and South Forks of the Toutle to the lower Cowlitz River and thence to the Columbia River. An estimated 2500 acre-ft of sediment and debris were deposited in the Cowlitz River. During the May 18 geological event, ash fell over a 100,000 sq mi area to the east. The depth of the ashfall varied from about two inches at Ritzville, Washington to almost an inch at Pullman, Washington. A conference was held in Pullman, Washington shortly after the eruption to evaluate the immediate situation and the data gathered up until then (July 8, 1980). The assembled information indicated that a wide range of possible effects from the eruption and ashfall could influence both the quality and quantity of water in the states impacted by the eruption. This information was carried back to Washington, D.C. by several members of the Pullman meeting. The U.S. Congress, recognizing both the seriousness of the threat to the water resources of the Pacific Northwest as well as the unique opportunity to investigate the effects of a volcanic eruption, appropriated two million dollars for research, to be administered through the U.S. Office of Water Research and Technology. In October, 1981, a conference with the title, ' Mt. St. Helens: Effects on Water Resources, ' was held at Jantzen Beach, Portland, Oregon to present the preliminary research findings and to exchange and transfer information with such agencies as the U.S. Forest Service, Geological Survey, Army Corps of Engineers, Soil Conservation Service and the Bureau of Reclamation. State agencies were represented as were state legislators, industrial firms, and consultants as well as interested individuals.

S. Army Corps of Engineers). The tolerance and label amendment efforts done by the USBR are reported. Experimental small-plot applications of 2,4-D dimethylamine (DMA) and butoxyethanol ester (BEE) at rates of 20 and 40 lb. acre (22.5 and 45 kg/ha) were made at Banks Lake, Washington and Fort Cobb Reservoir, Oklahoma with subsequent water, hydrosoil, invertebrate organism, and fish flesh sample collection and analysis for residues, through 56-days posttreatment. The temporary potable water tolerance of 0.1 milligram/liter was exceeded in three 1-day posttreatment samples (of 1680 water samples analyzed of 0.18% of the total samples). No dichlorophenols were found in water, but dimethylnitrosamines in the microgram/liter range were detected in a few pretreatment and posttreatment samples from both sites. Hydrosoil 2,4-D residues were low, with concentrations ranging from 0 to 0.316 micrograms/gram of soil resulting from a 45 kilogram/ha BEE application. Trace amounts of 2,4-D dichlorophenol in the microgram/liter range were found in some hydrosoil pretreatment and posttreatment samples. Herbicide residues in fish flesh were well within the 1 milligram/liter food additive tolerance, with no evidence of bioaccumulation.

Elbert Pumped-Storage Powerplant on the ecology of Twin Lakes. Twin Lakes are a pair of connected dimictic lakes, formed as the result of glacial action on alluvial deposits. A taxonomic species study is presented of the common plankton collected since 1974 from Twin Lakes. A total of 11 zooplankters and 14 phytoplankters were identified from the limnetic zone of Twin Lakes and the associated Mt. Elbert Forebay. The four divisions of zooplankton included four species of Rotifera, three species of Copepoda, three species of Cladocera, and one species of Mysidacea. The dominant zooplankters were the rotifers and copepods. The nocturnal opossum shrimp, Mysis relicta are abundant in Twin Lakes but were not collected in plankton samples. Cladocerans were rarely collected and made up less than 1 percent of the zooplankton population. The lower lake has a greater density of zooplankton than the upper lake. The four divisions of phytoplankton included three species of Chrysophyta, three species of Chlorophyta, six species of Bacillariophyta (diatom), and two species of Cyanophyta. The phytoplankton was dominated by the yellow-brown algae, Dinobryan, and the diatoms, Asterionella and Synedra. During 1981, average density of phytoplankton reached a maximum of 4870 organisms/liter during September in the upper lake; the average density in the lower lake peaked during March at 18,042 organisms/liter.

Compared to the original YDP design with 70% desalting recovery, additional removal of calcium in the desalting feed would allow recoveries < 90%. The sole chemical regeneration solution for the IX (ion exchange) process during steady-state operation would be the sodium-rich reject brine from the desalting equipment. Pilot plant equipment to test this process was operated at the YDTF (Yuma Desalting Test Facility) and consisted of an IX unit and an electrodialyzer to supply reject-brine regenerant for the IX experiments. Because the reject-brine contained major concentrations of sulfate, gypsum scale occurred in the resin bed under certain IX operating conditions. Scaling occurred especially when the water temperatures were 30 C in the summer. Scaling did not occur with water temperatures of 15 C in the winter. Gypsum scale buildup in the resin bed could be avoided by regeneration with a high upward flow rate causing a fluidized bed. Multiple regression analysis of the IX data delineated the importance of several control variables in the IX experiments, including regeneration concentration, flow rate, volume, and temperature. Results show that ion exchange high recovery pretreatment process is feasible , and that it is technically possible to achieve high recovery in the YDP.

The PFM-EC electronically drives the PFM-T (plugging factor monitored-tester) to obtain the necessary data for calculating a plugging factor for a sample of water. The quality of prefiltered feed water delivered to the membranes of reverse osmosis, membrane-type desalting plant largely determines membrane performance and longevity. The process of making a measurement consists of the following basic steps: measure the amount of time it takes to pass a given volume of water through a specified filter membrane at the regulated pressure; continue to pass water through the filter for the specified cycle time (typically 15 minutes) while maintaining the same pressure; and measuring the time. The PFM-EC interfaces to other computer systems, has battery backups, and magnetic tape storage. The PFM-SPSBP draws continous flow samples of test water from 1 to 6 preselected sources. Each sample of water is pumped to the PFM-tester at a back controlled pressure for the duration of the time required. The PFM-SPSBP is capable of operating in an industrial environment without air conditioning. Engineering drawings include: electronic controller hardware overview, operator interface, flowchart, and schematic diagrams.

Cores were taken from the dam in 1938, 1940-41, 1945, 1949, 1956 and 1980, following the onset of visible cracking due to alkali-aggregate reaction. Test data from 1980 cores are reported and compared to earlier core data. The concrete from Parker Dam was, in most cases, stronger in 1980 than when completed in 1938. There were apparent strength reductions in the top portions of the dam from 1938 to 1956, with a rebound in strength since that time. Evidence of alkali-aggregate reaction was found throughout the dam as substantiated by the petrographic analysis. Further evidence was the reduction in modulus of elasticity at all elevations in Parker Dam, although a rebound in modulus of elasticity appears to occur in recent years. The alkali-aggregate reaction is most severe in the upper portions of the dam, resulting in a higher incidence of disbonded construction joints. Assuming that most of the reactive silica and alkalies have been consumed, very little future deterioration will take place as the result of alkali-aggregate reaction.

Data gathered was used to compute a revised reservoir capacity due to the volume of accumulated sediment since the dam was closed in 1949. Sixteen sediment samples were collected from reservoir deposits at various sediment ranges in the upstream portion of the reservoir. Sonic depth recording equipment was used to profile the sediment ranges. Reservoir capacity was determined using contour surface areas computed by the width-adjustment method. The original surface area of Angostura Reservoir in 1949 was 4,841 acres and the capacity was 159,919 acre-feet at the normal water surface elevation of 3,187.2 feet. The 1979 survey resulted in a surface area of 4,612 acres and a capacity of 130,768 acre-feet at the same normal water surface elevation. This indicated a loss of 29,151 acre-feet in capacity in the 29.6 years since the dam was built. JF - Available from the National Technical Information Service, Springfield VA 22161.

Simulation microsystems were prepared for four sites located in the north arm of the reservoir basin including two sites located in an abandoned acid mine tailings pond. Data obtained from the tailings pond microsystems indicated that low pH water and high trace metal concentrations will exist in the north arm of the reservoir. These data suggested that some kind of membrane or compacted earth lining will be necessary to seal and contain the mine spoilage. Other sites in the reservoir basin exhibited normal water quality. Near the proposed dam, anaerobic conditions will develop rapidly due to high available concentrations of organic carbon, and the subsequent release of zinc, iron, and manganese may pose a water quality problem. In the north arm near Keetley, simulation data indicated that anaerobic conditions will not develop as quickly or be a severe as conditions expected near the dam. Overall, the availability of nitrogen and phosphorus forms in the Provo River and Jordanelle sediments indicated that possible problems with algal blooms may exist in the reservoir.

Final Report AN - 18982648; 8504195 AB - The Southwest Drought Research Program is a cooperative research effort between the Bureau of Reclamation and State agencies in Arizona, Colorado, Oklahoma, Texas, and Utah to define and plan how the Southwest States can best use cloud seeding technology to mitigate droughts. Institutional studies examined issues of authorization for cloud seeding, organization for decision making and communication, and funding for cloud seeding. Technical studies included climatology of drought and nondrought periods, weather modification potentials, and probable net economic and agricultural benefits and probable social and environmental impacts of cloud seeding for drought mitigation. Results indicate that seedable clouds occur during drought but with less frequency than during nondrought periods; estimated seasonal precipitation increases range from 5 to 20%; additional precipitation in drought periods has a benefical economic effect; weather modification makes its greatest contribution to drought mitigation if it is applied in a long-term program to maintain soil moisture and water storage at near-normal levels; there is no interstate uniformity in laws and procedures governing weather modification.

The technique provides predictive data on planned or existing reservoirs and lakes by duplicating conditions expected at the sediment-water interface including anaerobic (chemically reducing) conditions which may occur in the hypolimnion during summer and winter stratification. Using many small sediment-water ' microsystems ' allows for replication and the estimation of experimental error, as well as application of a variety of analytical chemical techniques for characterizing the simulation water. The relatively small size of microsystems offers economies of scale advantages compared to some previously suggested simulation techniques. Because all the microsystem water is prepared for chemical analyses, the problem of microstratification seen in larger sediment-water systems is reduced. Microsystems are easier to seal, which minimizes the chance of oxygen contamination. Data obtained using this technique represent worst case rather than actual water quality conditions.

Various models were employed to test the effect of alterations intake size and shape, and the effects of a bulkhead slot, a pier in the intake, a draft tube, and different approach channel configurations. Using straight surfaces in place of curved bellmouth entrances and shortening the length of the intake could significantly reduce construction costs. In addition, reducing the intake size would reduce the size of trashracks, gates, and associated operating equipment.

The 1972 and 1979 to 1980 LVS water analyses data were reevaluated and compared to evaluate uniformity of water analysis from each of the 14 springs, monthly variations in spring water analyses, differences between spring water and borehole water analyses, characteristics of spring water, and differences between the 1972 and 1979 to 1980 spring water analyses. The analyses of water taken from 10 of the 14 springs in 1972 suggest that the water issuing from each spring comes from the same source. Throughout the 1972 tests, dissolved Ca, Mg, K and Na salt concentration varied < +/- 5% from the average values. The average value of total dissolved solids (TDS) was was 9770 milligrams/liter and remained constant at 9800 milligrams/liter during January through May. The TDS dropped to a low of 9670 milligrams/liter in June but gradually returned to 9800 milligrams/liter by December. The water from all of the springs and the borehole seemed to come from the same source. The spring water tested in 1972 and again in 1979-1980 had comparable average values of Ca, Mg, K, sodium bicarbonate, chloride, and sulfate dissolved salts. The average values of dissolved salts for the two test periods compared within the variations expected from sampling and analytical errors.

The Dotsero Springs are located in the Leadville limestone strata. Because of the high bicarbonate content of the Dotsero Springs Water, calcium could be reduced from 260 to 125 mg/l by partial lime treatment. Trace metals and trace anions were at a concentration of 0.1 mg/l or less and raw water met the toxicity limits for drinking water. Dehydrated salts or lime treatment sludges would not exceed toxicity limits for Resource Conservation and Recovery Act hazardous waste. The Glenwood Springs (GS) are located in the Leadville limestone strata. Because of the high bicarbonate content of GS water, calcium could be reduced from 470 to 238 mg/l by neutralization with lime (calcium hydroxide) to precipitate calcium carbonate. The trace metals and trace anions were less then 0.1 mg/l. The raw water exceeded or approached the limits of toxicity for drinking water for cadmium , chromium, fluoride, and selenium. However, chemical pretreatment and desalting necessary to bring water to below TDS limits would reduce cadmium, chromium, fluoride, and selenium below limits. The combined flow rate for the 25 identified surface springs (14 GS, plus 11 DS) of the GS-DS unit is 0.516 cu m/s (18.23 cu ft/s). The flow rate weighted average TDS for the unit is 15,016 mg/l. The salt load for the 11 DS was 69,050 metric tons annually and for the 14 GS was 174,700 metric tons annually. JF - Available from the National Technical Information Service, Springfield VA 22161.

This concern is now being translated into private and public sector initiatives to implement waste disposal and other policies designed to protect groundwater. These activities generate substantial costs; the purpose of this paper is to establish a framework with which to measure the benefits of such efforts to protect groundwater. This benefits framework is based on the premise that the probabilistic value of protection is at least as great as the expected costs of contamination. These costs are shown to be sensitive to a variety of site-specific hydrogeologic and water use factors and general economic parameters. By facilitating benefit-cost comparisons, the framework provided here should help direct groundwater protection resources to their most efficient uses.

To raise the reservoir elevation 3.05 m, four radial gates were to be added to the double-curvature spillway. Spillway pressures were measured for a flush sillplate and a raised sillplate to accommodate the gates to the curvatures of the spillway. Discharge calibration curves were determined for various gate openings. Hydraulic performance of the proposed spillway modification proved satisfactory. At the design reservoir elevation of 97.8 m and with the gates fully opened, the release was 376.6 cu m/sec. A higher discharges, damage to the gabions and control house by scour, flood, or wave action appeared possible. It was recommended that calibration curves for gate openings smaller than 152 mm be determined in the field by gaging the stream. Four-gate operation is recommended for as low a discharge as is compatible with accuracy requirements and/or confidence in the calibrations developed from the downstream gaging.

Results showed that the 3-hp variable-speed motor controller is sufficient to provide variable speed operation on the large gage hoists to be installed on the Granite Reef Aqueduct. Noise interference produced by the controller is low enough to be used in the field without causing interference to microprocessor, electronic, and communication circuits. The motor controller must be matched to the motor with respect to horsepower rating and revolutions per minute. The Parajust controller which is temperature rated conservatively will provide cyclic duty at elevated temperatures. D-C voltage motors with controllers provide better low speed control and are more efficient and economical for large horsepower ratings. A-C voltage motors with controllers offer lower cost, especially for induction motors, and require no brushes or slip rings. JF - Available from Engineering and Research Center, Denver CO.

The characteristics and observed stability of fine and coarse soil cover layers placed on 16 selected canal reaches to resist water erosion and to protect asphalt, plastic membrane, and compacted earth linings are reported. The canal test locations, canal design characteristics, physical properties of the covers, and observations on the performance of the covers over periods up to 25 years are given. Based on the experience of the Bureau of Reclamation with the performance of the test reaches, a range of grading for granular covers to control erosion on canal linings with similar conditions is proposed. Soils which have generally performed well in coarse cover layers on canals with tractive forces less than 0.1 lb/sq ft (5 N/sq m) have contained: (1) Maximum particle sizes between 3 and 6 in. (75 and 150 mm); (2) less than 50 percent passing a No. 4 (4.75-mm) sieve, and less than 10 percent passing a No. 200 (75-microm) sieve. To control sloughing of cover soils, consideration should be given to the grading of fine soil beneath coarse granular layers, and where economically justified, controlling moisture and density.

Elbert Pumped-Storage Powerplant on the ecology of Twin Lakes. Twin Lakes are a pair of connected dimictic lakes, formed as the result of glacial action on alluvial deposits. This report presents a taxonomic species study of the common plankton collected since 1974 from Twin Lakes. A total of 11 zooplankters and 14 phytoplankters were identified from the limnetic zone of Twin Lakes and the associated Mt. Elbert Forebay. The four divisions of zooplankton included four species of Rotifer (rotifer), three species of Copepoda (copepod), three species of Cladocera (cladoceran), and one species of Mysidacea (oppossum shrimp). The dominant zooplankters were the rotifers and copepods. The nocturnal opossum shrimp, Mysis relicta are abundant in Twin Lakes but were not collected in plankton samples. Cladocerans were rarely collected and made up less than 1% of the zooplankton population. The lower lake has a greater density of zooplankton than the upper lake. For example, in July 1981, average zooplankton densities in the lower lake reached a maximum of 116 individuals/L, as compared to 53 individuals/L in the upper lake. The four divisions of phytoplankton included three species of Chrysophyta (blue-green algae), three species of Chlorophta (green alg), six species of Bacillariophyta (diatom), and two species of Cyanophyta (yellow-brown algae). The phytoplankton was dominated by the yellow-brown algae, Dinobryon, and by the diatoms, asterionella and Synedra. During 1981, average density of phytoplankton reached a maximum of 4870 organisms/L during September in the upper lake; the average density in the lower lake peaked during March at 18,042 organisms/L.

Pallid sturgeon occur in the Missouri River and the lower half of the Mississippi River and certain of their tributaries. Of the 250 pallids that were reported, approximately 76% were collected from the Missouri River in Montana and the Dakotas. Because of the rarity of this species, information on its life history is limited. Regression equations were developed for the length-weight relationships of pallids from two Missouri River reservoirs. The apparent rarity of the pallid sturgeon and the lack of knowledge concerning it has prompted 9 of the 13 states within its range to classify it as either threatened or endangered or to give it some other special recognition. The Endangered Species Committee of the American Fisheries Society has also classified it as threatened throughout its range. Additional information is needed on its habitat requirements if it is to be protected from habitat destruction or modification.

The first project water was delivered to the area in 1952 and the project was completed in 1957. This solved the water supply problem by giving the District a dependable supply of better quality irrigation water. Leaching and other land reclamation practices greatly improved the land productivity. However, the plentiful supply of Colorado River water caused the groundwater table to rise and created a serious drainage situation. Although it is very difficult to isolate the effects of individual measures of the irrigation efficiency improvement program, the first and most dramatic results were realized from the removal of approximately 2,500 ha (6,200 acres) of irrigated land from the District. The next most effective measures are the On-farm Improvement Program and the Water Management and Conservation (WMC) Program. Precise, laser controlled leveling of fields that are designed to accomodate soil conditions, along with larger heads of water delivered through concrete lined farm laterals and turnouts, has been highly effective in reducing water use rates and deep percolation. Treatment on a total of 17,300 ha (42,800 acres) is expected to be accomplished by 1986 with the possible effects of reducing on-farm deep percolation below 123 ,500 cu dam/yr (100,000 acre-feet/yr). The WMC Program enables the irrigator to get optimum results in production with a minimum amount of water and to get the best use of efficiently designed farm units. Up to 14,200 ha (35,000 acres) of land, both onfarm treated and other efficient units, have utilized the WMC Program. This program has spread to about 6,100 ha (15,000 acres) in other districts of the lower Colorado River water service area.

Environmental analyses of the Title I Project were presented in the Final Environmental Impact States (EIS) filed by the Burea of Reclamation on June 10 , 1975. The EIS made an in-depth determination of the salinity control project 's impacts, both adverse and beneficial. While the EIS discussed the types and relative amounts of environmental imapcts, definite plans for their mitigation were not developed until after the EIS was finalized. Some of the project 's adverse impacts were avoided prior to development of an actual mitigation plan by simply incorporating measures into both the project design and the construction schedules. Some of these measures were: using the existing main outlet drain as a conveyance channel for salt water wastes; screening the feed water intake to the desalting plant to reduce fish losses; conducting fish salvage during canal dewatering works; and providing bridges, siphons, and escape ladders in and along the canals for both human and wildlife use. Two separate fish and wildlife Ad Hoc Committees were formed to develop the mitigation plans for this project. One committe was responsible for mitigation of adverse impacts associated with the concrete-lined canal in California, and the other Ad Hoc Committee dealt with the effects from the desalting plant and the protective and regulatory pumping. Both committees were to remain in effect until mitigation concepts were thoroughly planned, designed, and implemented. In total, eleven accepted recommended proposals were expected to recover 67.5% of the fish and wildlife losses expected to result from the Title I Salinity Control Project. The most significant facet of the mitigatino process yet to be completed is the evaluation of the effectiveness of the implemented mitigation measures.

This salt loading, was quantified based on an analysis of an inflow-outflow river budget, showing that a river budget can be used to estimate accurately the salt pickup. The mean annual salt pickup from the entire Grand Valley was about 528 million kg/yr, or 6% of the total average annual salt loading to the river. Although annual values fluctuate widely, there is a 95% confidence limit on the mean of + or - million kg/yr. No significant trend in salt pickup was found, indicating that the salt loading appears constant over 29 years of study data.

Studies have determined that an annual benefit of $540,000 (1983 prices) can be realized by a reduction of 1 mg/L as salinity concentration in the Colorado River approach 1,000 mg/L. The project is feasible, and when completed will benefit the Colorado River system. Deep-well injection as a method of disposal will reduce the original plan 's project costs by one-half to one-third, a savings of about $60,000,000 to the American taxpayers. Drilling and testing of the first test disposal well is scheduled for early 1984. (See also W87-05165) (Lantz-PTT) JF - Salinity in Watercourses and Reservoirs.

The foremost reason for Federal and State participation is to reduce salinity in the Colorado River at the lowest cost and, where possible, to use the saline water beneficially. The prime goal of private industry is to achieve an economically competitive, long-term method of transporting coal and other commodities from Wyoming, Colorado, and Utah to domestic markets in the southwest U.S. and possibly export markets. New opportunities for pipeline use are emerging as AQUATRAIN progresses, and technology development is continuing. Project support is widespread and growing rapidly. The Basin States, through the Colorado River Basin Salinity Control Forum, have indicated their support by participating in addressing State issues. Regional and local support is anticipated and, on a national level, early discussions with commodity producers, transportation companies, utilities, and port facility developers have been positive. Studies to be done in the planning stage, scheduled for mid-1983 to mid-1985, will be used to determine the feasibility of the system.

The retention time of the system has increased to the range of 4-6 years. This retention time has decreased both the seasonal and annual variability of salinity in the basin. The Colorado River is currently behaving as a mixed reactor system rather than the plug flow systems of its natural state. With the system operating at near capacity, water in excess of demands can no longer be stored by the system. This will increase the average discharge through the Colorado River by approximately 2.5 cu km/yr. This excess in flow will effectively dilute the salinity in the Lower Basin. Development in the Upper Basin will eventually reduce the flow through the system and cause an increase in salinity as depletions come online in the future. Until further development occurs, average or wet periods, combined with the reduced capacity to store excess amounts of water, will continue to keep salinity down and periodically cause salinity to drop as it did in 1980.

The purpose of the Grand Valley Unit is to reduce the salt loading to the Colorado River attributable to agricultural practices by improving the water delivery system and installing on-farm improvements. To assess the effectiveness of Stage One improvements on groundwater flows and salt loading, a hydrologically-closed basin, known as the Reed Wash study area, has been equipped to monitor surface and groundwater inflows, outflows, and levels. A monitoring program was implemented to establish preconstruction hydrologic conditions and to observe the effects of canal lining and lateral piping on salt loading in the watershed. The monitoring program indicates that the water system 's improvement has been effective in reducing seepage and salt loading from canals and laterals. The Reed Wash area will be monitored for a number of years to verify the effectiveness of the lining program. The year 1983 was the first year with the entire program installed. The results of the monitoring program could influence the predicted effectiveness of other salinity control projects. (See also W87-05165) (Lantz-PTT) JF - Salinity in Watercourses and Reservoirs.

The river, while nearly pure at its origins in the snowcapped Rocky Mountains, carries about 8 million megagrams (9 million tons) of mineral salts annually past Hoover Dam. The salt pollution damages irrigated crops, causes accelerated plumbing replacement and appliance wear, and causes annual damages of over $120 million. Projections are that without any controls, annual damages of over $238 million will occur by about 2010. Average annual economic losses of $120 million from increasing salinity in the Lower Basin of the Colorado are impressive. Salt pollution affects more than 10 million people and 405,000 ha or irrigated farmland in the United States. About 70% of the economic losses are associated with municipal and industrial use and occur when salinity concentration levels are above 500 mg/L. For irrigators , the higher concentrations cause decreased crop yields, altered cropping patterns, higher leaching and drainage requirements, and higher management costs. Economic losses to agriculture (either through lower yields or higher production/management costs) usually begins when salinity levels of applied irrigation water reach 700 to 850 mg/L, depending upon soil conditions and type of crop grown. Alternative ways of solving the salinity problem depend partly upon the way the salt enters the river. More than a third of the salt enters the river from irrigation sources. Some of these are: irrigation source model, point source control, and diffuse source control. In order to minimize risk, staging or incremental implementation of project features is being used on several units. Staging allows additional time to monitor actual results and minimize investment if certain features are not proved effective.

This increase occurred during a period when there was a much smaller (11%) increase in salt yield at the upstream (7200) station. However, analysis of water discharge data and station salt-loading functions (Q vs. TDS) indicate that 94% of the increase in annual salt yield at the downstream station is due to the increase in mean monthly flow following the beginning of construction of the wildlife management area, and 6% of the increase is due to a small though statistically significant (alpha=0.05) change in the salt loading function (Q vs.TDS) at the downstream station. It is hypothesized that increased inflows from Castle Peak tributary caused downstream flows during the post-construction period to increase proportionally more than flows entering the area upstream. Based on the analysis of the existing data at Pariette Draw, it s believed that a 300 ha expansion of the wildlife management are will result in a maximum increase of approximately 540 to 630 mg of salt/yr in the Colorado River (based upon an increase of 1.97 mg/ha/yr at the existing wildlife area). Approximately 7,700,000 cu m/yr of water can be expected to be consumed by the wildlife management area. (See also W87-05165) (Lantz-PTT) JF - Salinity in Watercourses and Reservoirs.

The concentration progressively increases downstream as a result of diversions and salt contributions from various sources and at its peak in 1965 was approximately 925 mg/L at Imperial Dam. Due principally to surplus flows, the salinity concentration at Imperial Dam has been gradually declining and was approximately 750 mg/L in 1980. The recent decreases in salinity concentration are viewed as short-lived and it is estimated that the concentration at Imperial Dam could rise as high as 1,070 mg/L by 1995 without a salinity control program. Approximately three fourths of the salt load and virtually all of the flow in the lower Colorado basin originates in the upper basin. Possible options for slowing down the projected increases of salinity concentration fall into three broad categories: (1) Prevent saline water from entering the Colorado River; (2) Reduce salt pickup of waters entering the Colorado River; and (3) Provide extra water for dilution of salinity. There are legal and institutional constraints which increase the difficulty of implementing many of the proposed salinity control projects. Some of the constraints relate only to one of the categories mentioned above, but others are broader, affecting virtually all salinity control options. Major constraints are: (1) state recognition of evaporation or injection as beneficial use; (2) costs incurred to implement projects; and (3) concern for supplies within each region (city, state, etc).

HIPLEX (High Plains Cooperative Program) was designed to reduce scientific uncertainty associated with attempts to increase rainfall by cloud seeding in the High Plains. Field programs were conducted at three sites. A randomized experiment, HIPLEX-1, was set up in Montana to test a physical hypothesis linking dry ice seeding to rainfall from cloud base. HIPLEX has confirmed the importance of ice processes to precipitation formation in cumulus clouds of the High Plains and the dominance of mesoscale convergence/divergence fields on convective cloud development. HIPLEX-1 clearly showed increases in cloud ice concentrations associated with dry ice seeding 2 and 5 min after treatment time. Some changes in the subsequent steps in the physical hypothesis linking seeding to increased rainfall at cloud base are indicated but cannot be firmly established with the present data set.

AN - 14423845; 1336996 AB - In 1977 and 1978, the authors studied red-breasted mergansers Mergus serrator nesting on islands in northwestern Lake Michigan to determine whether environmental contaminants were having effects on reproduction. The authors looked for effects of individual contaminants and combinations of contaminants on reproductive measurements such as nest desertion, failure of eggs to hatch, death of newly hatched ducklings, percentage hatching success, number of ducklings leaving the nest and eggshell thickness. They also looked for relationships between the levels of some contaminants in blood samples of 39 incubating females and reproductive success. A small degree of eggshell thinning was attributed to DDE and a few other statistical tests were significant, but no contaminant or combination of contaminants measured seemed to have a pronounced effect on the aspects of reproduction we followed.

The mean interval between eggs laid was greater for hens fed 10 ppm ABATE) than for controls. Clutch size, fertility, hatchability, nest attentiveness of incubating hens, and avoidance behaviour of ducklings were not significantly affected. The percentage survival of ducklings to 21 days of age was significantly lower in both treated groups. In 21-day-old ducklings, aspartate aminotransferase (AST) activity increased and plasma nonspecific cholinesterase (ChE) activity was inhibited by about 20% in both treatment groups, but there were no significant differences in brain AChE or plasma alanine aminotransferase (ALT) activities, or plasma uric concentration.

After bacteria were inactivated with chloroform, whole cells, soluble antigen and combined whole cell plus soluble antigen vaccines were prepared. Those brook trout (Salvelinus fontinalis ) that were vaccinated by a 60-second immersion in the combined whole cell plus soluble antigen vaccine were protected against experimental challenges. Further immersion vaccination of Atlantic salmon (Salmo salar ) in the combined vaccine indicated that protection conferred by immunization was highly significant, efficacious, and reproducible.

AN - 13935614; 781796 AB - Fish abundance and population stability were compared in the tailwater and in an unregulated tributary of Barren River Lake, a food control reservoir in south central Kentucky. Fish abundance was greater in the tailwater near the dam and was dominated by three species common in the reservoir: gizzard shad (Dorosoma cepedianum ), bluegills (Lepomis machrochirus ), and white crappies (Pomoxis annularis ). This study suggests that the occurrence of reservoir species in the tailwater was the result of fish passage from the reservoir during high discharges in fall and winter. Reservoir operations (altered flow, low summer water temperature, and poor summer water quality) probably were responsible for the unstable populations of common carp and riverine suckers in the tailwater.

The method is used in the Mid-Pacific Region of California and its application is limited to canals subdivided by check structures into individual pools, which can be tightly closed. Water depth is measured at the upstream and downstream ends of all pools during standstill time with check gates completely closed. The difference in depth corresponds to the invert gradient of a pool and is constant in stable areas. Changes in the difference reflect the amount of subsidence during the time interval between sets of measurements. Examples are given of the application of the method to two canals in California. In long pools, intermediate measurements were made at fixed structure sites, such as bridges.

This species is the sole food item of the endangered Everglade kite. It was considered likely that information generated by investigators attempting to control snails (schistosome fluke hosts) might be useful to investigators attempting to protect snails. Information on 10 species shows that copper is toxic to snails at lower concentrations than that applied in aquatic exotic weed control where the need to protect the apple snail is critical.

Therefore, control of fish diseases, like the control of human diseases, is not a matter of simple, superficial diagnosis and prescription of medication. Control is based on an understanding of all factors contributing to disease. This is a wide approach in which people with medical, biological, and chemical training must participate to obtain the best results in fish culture.

AN - 13790958; 647555 AB - Methods were developed for in vitro screening of candidate aquatic fungicides for efficacy against Achlya flagellata, A. racemosa, Saprolegnia hypogyna and S. megasperma . Agar plugs containing fungal hyphae, removed from the edge of actively growing colonies, were placed in the depressions of spot plates containing 1 multiplied by 0, 10 multiplied by 0 and 100 mg/l of the candidate compounds for 15 or 60 min. After exposure, the plugs were transferred on to filter papers (0 multiplied by 45- mu m pore) in a holder, rinsed, and then placed on cornmeal agar medium in tri-petri dishes. Criteria for the acceptance or rejection of candidate aquatic fungicides for further study were based on the antifungal spectrum index (ASI) comparisons between respective compounds and malachite green after 48 h and the concentration level producing complete growth inhibition. This method provides a base from which in vivo and definitive test regimens can be developed. Preliminary in vitro screening of candidate fungicides reduces the need for costly in vivo tests on compounds that have low antifungal activity.

AN - 13782508; 636828 AB - Vast deposits of oil shale are contained in the Piceance basin in northwestern Colorado. The basin may contain as much as 40 million acre-feet of stored water associated with these deposits, much of which may have to be drained for mining. Yet, most analyses of water-supply for oil-shale development have focused on surface water with only brief mention of ground water. This study used a synthetic streamflow model to investigate the effects of using conservative estimates of ground water on the required active storage capacity of a hypothetical reservoir on the White River. Results of the study indicate that use of ground water from mine drainage and/or auxiliary wells may have a significant impact on the size and timing of surface-water reservoirs. Thus, ground water may be an important source of supply, particularly during early development of an oil-shale industry. The study results strongly suggest that further investigations are needed on the physical availability of ground water as well as the institutional, legal and water-quality constraints on its use.

AN - 13759530; 621480 AB - The Blue Plains wastewater treatment plant is the largest point source of phosphorus in the Potomac River basin, discharging an average of 2,000 kilograms of phosphorus into the tidal river each day. Following a one-tidal-day continuous dye injection, high-resolution time-series sampling was conducted in August 1980 to determine the mean value and time variation of the linear decay constant for dissolved phosphorus at various locations near the treatment plant. Using an analytical solution to the two-dimensional solute transport equation as the conceptual guide, values of the decay constant for dissolved phosphorus were computed for 72 samples collected at 50 minute intervals at each of four stations.

Elbert Pumped-Storage Powerplant on Twin Lakes, Colorado: 1981 Report of Findings AN - 18999588; 8603336 AB - A series of studies is being performed to identify and quantify changes that occur in the aquatic ecology of Twin Lakes, Colorado, because of the Mt. Elbert Pumped-Storage Powerplant, which began operation in August 1981. The results presented here are part of the investigations being done by the Bureau of Reclamation on the ecological effects of pumped-storage construction and operation. These studies have been going on since 1971. The Twin Lakes and the powerplant are being used for the primary field investigations. Although it is too early to identify any ecological changes, this report presents results of studies done in 1981. These results, along with those from other studies done since 1971 when the project began, are being used to define the preoperational limnology of Twin Lakes. Twin Lakes are a pair of dimictic, connected, montane, drainage lakes of glacial origin. Based on seven limnological parameters, the lakes are classified as oligotrophic lakes. Maximum water temperature of 18 C were recorded in August 1981 for both lakes. The lowest measure dissolved oxygen concentration during 1981 was 1.7 mg/L at the bottom of the lower lake in October. Total phosphorus concentrations during 1981 ranged from 1 microgram/L, which has been the case most of the time during the past 6 years , to a high of 31 micrograms/L. Nitrate nitrogen concentrations ranged from <10 to 170 micrograms/L. Average daily primary productivity rates during 1981 ranged from a low of 84 mg C/(sq m.d) in the upper lake during March to a high of 126.6 mg C/(sq m.d) in the lower lake during May. Chlorophyll a concentrations during 1981 ranged from a mean concentration of 0.4 mg/cu m in the lower lake during May to a mean of 18.8 mg/cu m in the upper lake during September. Average phytoplankton and zooplankton densities reached maximums of just over 18,000 organisms/L (lower lake - Sept.) and 153 individuals/L (lower lake - June), respectively. Phytoplankton populations were dominated by diatoms and dinoflagellates, while zooplankton populations were dominated by copepods, opossum shrimp, and various species of rotifers. Large pelagic cladocerans are notably absent from Twin Lakes. The benthos includes chironomid larvae, oligochaetes, and fingernail clams.

The three types of soil were: (1) soil A-shale pediment/recent alluvium, (2) soil D-shale pediment/recent alluvium, and (3) soil A and weathered shale dissected Mancos shale uplands. Final infiltration rates on residual shale derived soils were 0.13-0.50 cm per hour. No runoff was generated on cracked soils derived from aeolian deposits. A steep dissected Mancos shale upland produced 180 times the suspended sediment concentrations and 68 times the EC (indicating salinity) compared to a low relief shale pediment and recent alluvial surface. Rilling was responsible for 80% of the sediment produced on the steep dissected shales. Channel scour and soil creep were also significant contributors to sediment. An estimated 1.35 million g per ha per year of sediment is produced by the steep dissected shale uplands. Sediment plugs were effective in trapping sediments on a local basis to improve quality of water for stock ponds and irrigation canals.

These clays are highly susceptible to erosion and are unsuitable materials for earthwork construction. Changes to the original test procedure developed by Dr. James L. Sherard included increased emphasis on the use of system flow rates in the classification of dispersive soil grade, reduced emphasis on the qualitative test evaluation criteria such as final eroded pinhole size and discharge effluent turidity in the final dispersive grade classification, and designing the equipment to assure atmospheric pressure at the pinhole discharge and verification of the actual hydraulic head on the system. Routine laboratory testing and analysis of Sherard 's original data was performed to substantiate proposed changes. An extremely high degree of correlation was found between solid originally classified as dispersive by Sherard on the basis of effluent turbidity and subsequently reclassified as dispersive on the basis of system flow rates. The quantitative method of evaluating pinhole test results on the basis of flow rates showed considerable improvement over the original qualitative methods because subjective criteria and operator bias are eliminated.

The data were also used to compute the volume of sediments that had accumulated in the reservoir since the gates of the dam were closed in 1909. Twenty-eight sediment samples from reservoir deposits were collected from various reservoir ranges throughout the lake. Sonic depth recording equipment interfaced with an automated survey system was used to run the hydrographic survey. Reservoir capacity was computed based on surface areas determined by a width-ratio method. The capacity of the reservoir is now 1.65 x 10 to the 9th power cu m (1,336,734 acre-ft), and the reservoir has a surface area of 7016 hectares (17,337 acres). Since 1909, 2.39 x 10 to the 8th power cu m (193 ,765 acre-ft) of sediment accumulation have resulted in about a 13 percent loss of capacity.

This canal, located near McCook, Nebraska, has a capacity of 6.3 cu m/s. The cement, in amounts of 4.5 percent by volume for one section and 2.5 percent for another was mixed with the soil in 600-mm-wide horizontal strips in the lining, which was otherwise constructed as a normal thick-compacted soil lining. In 1981, the cement-treated soil was sampled and laboratory compressive strength and durability tests were performed. Although the soil with 4.5 percent cement was cracked and had a blocky structure, it has resisted erosion reasonably well, even on a curve. The test reach with 2.5 percent cement resisted erosion slightly better on a straight section than the opposite untreated side. However, this section did not contain sufficient cement to adequately resist erosion on a curve. JF - Report No. GR-82-4 August 1982. 31 p, 14 Fig, 3 Tab, 13 Ref, 2 Append.

The impacted area showed salt concentrations as high as 468 milligrams/liter Na and 1215 milligrams/liter Cl within the plant root zone of the peat mat. The salt concentrations in the root zone decreased significantly each year from 1979 to 1981. Analysis of salt movement suggested that the salt was transported vertically downward by water movement through the peat mat following snow melt and heavy precipitation events each spring. Vegetation surveys in 1980 showed an absence of numerous native species in the salt impacted area; these were replaced by invading species. By 1981, many extirpated species had become reestablished in the impacted area after declines in salt concentrations. Salt tolerance studies on Sphagnum recurvum showed reduced growth in length at NaCl concentrations found in the bog.

The original spillway design included 8.23-m high gates which were not installed. Without the gates to increase the reservoir storage capacity, the requirements of future water users could not be met. An economical labryrinh spillway, was selected to increase the storage capacity of the reservoir because a longer length is provided for a given channel width. In plan, the spillway is a series of trapezoidal shapes. The Ute Dam spillway will be 9.14 m high and 1024.13 m in length, with 14 cycles. This spillway will provide the desired storage capacity and still pass the IDF (inflow design flood). The spillway is designed for 5.79 m of head which produces a flow magnification of 2.4. Impact pressures taken in the downstream channel will be used in the stability design of the spillway. At low discharges, subatmospheric pressures develop under the nappe near the top of the crest. Two splitter piers on each cycle alleviate these pressures. Velocities measured along the embankment provide information on slope protection required adjacent to the labyrinth.

The main purpose of the dam is to provide municipal and industrial water to Corpus Christi and adjoining areas. The reservoir also will provide some flood control and recreational benefits. A 1:80 scale hydraulic model of the Choke Canyon Dam spillway and stilling basin was studied to verify stilling basin design, flow conditions, and scour in the spillway approach channel. The dam will be 35 m high and have a crest length of 5640 m. The spillway chute is 112.2 wide and has a Froude number of about 4.4 at the stilling basin entrance. The stilling basin was designed to criteria developed for low Froude number flows. A modified entrance channel was developed as the model was tested. Stilling basin walls were shortened as a result of the model studies. The design recommemded for Choke Canyon Dam has a concrete apron 14 m long, downstream from the end of the stilling basin, followed by a 32-m long section of riprap. The design worked well for all discharges, and scour was limited to an area downstream from the riprap. (Moore-SRC) JF - Report GR-82-9 August 1982. 35 p, 25 Fig, 3 Ref.

The method, together with experience curves, allows damage to be estimated as a function of duration of operation. Procedures are given to design aeration grooves which can protect spillways from cavitation damage. Although the results of the study were derived primarily from tunnel spillway experience, preliminary investigations indicate that the curves are also applicable to chutes. More field experience is needed to better define the shape of the damage curve. (Baker-FRC) JF - International Water Power and Dam Construction Vol 34, No 8, p 13-15, August, 1982. 4 Fig, 6 Ref.

A model of the Auburn Dam entrance was constructed on a 1:15.74 scale. The model included the penstock entrance, trashrack seat, circular-to-rectangular transition, and a 4.57-m prototype diameter penstock. The Auburn Dam penstock entrance design had excellent hydraulic characteristics. The design had low intake losses and acceptable pressures along the intake surfaces. The semicircular trashrack seat in front of the intake had a positive effect in reducing intake head losses and pressure drops along the intake surfaces. The compound radius bottom curve of the penstock entrance was very important in reducing losses in the inclined penstock. The results from this study in combination with earlier results from the Grand Coulee Third Powerplant model study can be used in the design of other low-velocity conduit and penstock entrances for dams having vertical faces and horizontal penstocks or sloping faces and inclined penstocks.

Releases from the afterbay dam are used to provide uniform daily flow in the Big Horn River, leveling the peaking power generation from Yellowtail Powerplant. At times, gas supersaturation has occurred downstream from Yellowail Afterbay Dam, resulting in serious fish kills. A 1:24 scale model of Yellowtail Afterbay sluiceway was constructed to study the placement of flow deflectors designed to keep the water jets issuing from the sluiceway gates near the tailwater surface. Deflector plates installed on the curved invert of the sluiceway will reduce jet submegence, a cause of supersaturation. Measurements show no subatmospheric pressures present on the flow deflector lips. Waves within the stilling basin will be larger with the deflectors in place than with the existing configuration, while waves outside the basin will be the same size or smaller. With the flow deflectors in place, the largest velocities, and therefore the most flow, occur near the surface where the pressure is close to atmospheric. With the deflectors in place, material will not be brought back into the basin, although any material thrown into the basin will remain there.

A functional relationship was seen between four of the five shear moduli and the level of shear strain. The damping ratios decreased with increasing shear strain over the strain range of 0.001 to 0.2 inch/inch. This conclusion was opposite to results of past research into the damping ratios of dry sand. JF - July 1984.

St. Helens after the May 18, 1980, eruption were analyzed for organic compounds by capillary gas chromotography-mass spectrometry computer techniques. Alkanes, aromatic and polycyclic aromatic hydrocarbons, alcohols, fatty acids, dicarboxylic acids, ketones, aromatic acids, aldhydes, phenols, chlorinated aromatics, resin acids, terpenes, and insect juvenile hormones were identified. A total of 84 compounds were qualitatively identified in the ash, 42 in the bottom sediments, 73 in Spirit Lake water, and 71 in Coldwater Creek water. Nineteen compounds were common to both water samples. Many of these compounds, commonly found in pulp and paper mill effluents, adversely affect fish, insects, and other aquatic life, and cause oxygen depletion and tast and odor problems in streams. The most likely source of these compounds is the pyrolysis of plant and soil organic matter during and after the eruption. Although these hydrophilic compounds pose a potential groundwater contamination threat, no pollution has yet been detected in monitoring wells.

With this system, a continuous record of pan evaporation is obtained. The evaporation station may be left unattended for periods of up to 30 days, and with incorporation of a data telemetry system, could be operated on a real-time basis. Measurement sensitivity and frequency of maintenance trips can be determined by the investigator simply by choice of reservoir diameter and volume. The system is particularly well suited for remote evaporation stations. The major advantages of the system over conventional, manually read evaporation pans are: (1) savings in manpower and travel expenses, (2) continuous recoding function, and (3) adaptability to real time data acquisitions systems. Data retrieval and storage can be by conventional paper strip chart, punch tape, cassette tape data logger, or telemetry. The system could be operated in cold weather by substituting a mixture of methanol and water for water in the evaporation pan. For more sophisticated applications, the float valve can be replaced by an electronic circuit to sense water lever and a solenoid valve to control water flow to the pan.

This hypothesis was verified by applying basic flow mechanics and turbulence theories. By integrating the rate of turbulence energy production over depth of flow, depth-averaged suspended sediment concentration was expressed as a function of unit stream power. Total sediment concentration was also described as a function of unit stream power by the process and a procedure similar to that used by Einstein. Seven total load equations were evaluated by comparing the computed results with 1093 sets of laboratory data and 166 sets of river data. Results from equations based on the concept that the rate of sediment transport in a open channel flow is related to the rate of energy dissipation of the flow produced good agreement with measured results. This group included equations proposed by Yang, Englund, Hansen, and Ackers and White. Equations by Shen and Huang and by Maddock, which lacked depth parameters, were applicable to laboratory flumes and small streams but not to large rivers. The Colby method underestimated total bed load material loads in natural rivers and was not suitable for laboratory flumes.

A number of major landslide areas are located upstream from the dam. Under certain conditions it is possible that a slide could break free and plunge into the reservoir at velocities greater than 30 m/s. A physical model study was conducted to determine the magnitude of waves in the event such a landslide occurs. The model of 4.8 km of the reservoir and 1.3 km of the downstream canyon was constructed to an undistorted scale of 1:250. A wedge-shaped slide was used. It was found that the direction of the landslide as well as the volume of water displaced and slide velocity are important to the wave height in the vicinity of the slide. Waves directly in line with the slide direction were two to three times higher than waves not in line with the slide. Waves distant from the slide were solitary waves. Waves in the river downstream were bore waves. The maximum wave height at the dam due to a slide at one of the selected sites was 7 m. Nondimensional relationships were developed to predict wave heights for Morrow Point Reservoir and other cases as a function of slide velocity, water depth at the slide, volume of water displaced, and distance from the slide.

Elbert Pumped Storage Powerplant operations which began in 1981. Since it is too early to identify any ecological changes, these results along with those from other studies done since 1971 are being used to define the preoperational limnology of Twin Lakes. Maximum water temperature for both lakes recorded in August 1981 was 18 C. The lowest measured dissolved oxygen concentration during 1981 was 1.7 milligrams/liter. The pH ranged between 6.5 and 8.3, and conductivity levels were between 69 and 102 micro S/cm. Total P concentrations ranged from < 1 micrograms/liter to 31 micrograms/liter. Nitrate N concentrations ranged from < 10 to 170 micrograms/liter. Average daily primary productivity rates ranged from a low of 84 milligrams C/sq m/day during March to a high of 126.6 milligrams C/sq m/day during May. Chlorophyll a concentrations ranged from 0.4 milligrams/cu m to 18.8 milligrams/cu m. Average phytoplankton and zooplankton densities reached maximums of just over 18000 organisms/liter (September 1981) and 153 individuals/liter (June 1981), respectively. The benthos includes chironomid larvae, oligochaetes, and fingernail clams.

It was assumed that the saline water needed for pond construction would be transported to one of two dry lakebeds in the Basin (Danby Dry Lake in southern California or Sevier Dry Lake in western Utah) as part of a salinity control/coal transport project. The ponds would be used to generate electric power that could be integrated with the Bureau 's power grid or used in combination with thermal energy from the ponds to power commerically available desalination systems to produce freshwater. Economic benefits were compiled for two methods of concentrating the necessary brine for the ponds - one representing stage construction using collected brine only and the other using salt at the site to produce the concentrated brine. Results of the economic analysis show solar ponds offer benefit-cost ratios of 2.1 and 2.9 and annual cost savings of 41 and 61%, respectively, for baseload and intermediate load operations when compared to similar facilities powered by fossil fuels.

Significant frost heave in soils occurs in cold climates when certain fine-grained soils have access to sources of water and an open-freezing system exists. Under hetergeneous soil and moisture conditions, damage to structures is caused by differential movement during periods of freezing and thawing. The conventional methods of controlling frost action are: location of the foundation below the frost penetration level; replacement of frost susceptible soil with soil that this not affected by frost; restriction of the supply of water to the frost zone; and the use of insulation to reduce the depth of frost penetration. Bureau hydraulic structures which have suffered the most damage from frost action include: spillways; chutes and drip structures; checks, pipe turnouts, pier-supported pipe, and canal linings. Frost action is also a consideration in soil canal linings and in earth enbankment dams constructed in cold climates. A promising new technique to control frost heave is the use of polystyrene insulation. Field experiments with this insulation were conducted on the Riverton Unit, and the Pick-Sloan Missouri River Basin Program; it has also been used for small installations where special frost protection was required.

To meet the objective of finding methods for disposal of point source water or for reuse of the saline waters in energy development, a literature study was made and laboratory coal and water slurry tests were performed. Samples of water from BS (Big Sandy) River Wells, GS (Glenwood Springs), and DS (Dotsero Springs) were analyzed for major cations and anions, trace metals, calcium sulfate solubility, total organic carbon, pH, and conductivity. BS, and DS waters could be taken from their aquifers, passed through filters, and used without further processing as transport media in coal slurry pipelines. Any of the three waters can be deep well injected after recovery by dewatering of coal slurries. Chemical characteristics of recovered BS water make it a promising candidate for use as a secondary coolant in binary cooling towers. The GS and DS waters are good candidates for use in solar salt-gradient ponds because of high concentrations of sodium chloride. Owing to the high cost of chemical treatment and desalination, present use of BS, GS, and DS waters for irrigation is not an acceptable option.

This study is part of a series in the long-term evaluations of strength and elastic properties of concrete in various dams. The river plug concrete included two mix designs designated as interior and exterior. The dam concrete included two mix designs noted as high of low water to cement plus fly ash ratio. Results of the tests on the 3-year cores from the river plug show the average compressive strength of the concrete to be about 40 MPa, with no increase over the 6-month strength. The average 1-year dam concrete compressive strength was about 30 MPa, which is an increase over that at 6 months age. The modulus of elasticity for the interior plug concrete at 3 years is about 30 GPa with no significant increase with age. The 1-year dam concrete modulus of elasticity is about 35 GPa. Poisson 's ratio, density, mix design, and tensile strengths of construction joints and monolithic specimens are also discussed. JF - Report No. GR-80-7 March 1982. 38 p, 10 Fig, 8 Tab, 6 Ref.

This structure is unique in that it is one of three dams constructed with what was called sandcement. In 1978, concrete cores were drilled from six locations in the dam. The evaluation of these cores will be used in a feasibility study for the possible modification of the structure. Compressive strength tests indicate a low compressive strength but no significant reduction from the control strengths established during construction. The difference in strength and modulus of elasticity of the concrete when tested in a wet condition, compared to cores tested in a dry condition, was greater than usually observed between wet and dry concrete. No explanation for this behavior was determined. Minor evidence of silica gel was observed but not to the extent that the structure would be affected by an alkali aggregate reaction.

Elbert Forebay 1978-79 AN - 18956480; 8301268 AB - The forebay for Mt. Elbert Pumped-Storage Powerplant is located about 137 m above Twin Lakes, Colorado. Prior to the forebay construction, the area consisted of sagebrush, sandy soil, and stands of aspen. The constructed bottom was a 1.5-m thick compacted sandy-silt liner; however, in the fall of 1980, a chlorinated polyethylene (CPE) liner was added to decrease seepage. In 1977-78, the forebay was filled to 19% capacity with water pumped from Twin Lakes. Throughout the duration of the limnological study (November 1978-September 1979), the forebay had neither an inlet nor an outlet. It was found to be a cold monomictic impoundment. The forebay was higher in disolved substances, and nitrogen and phosphorus compounds, but lower in abundance of plankton and benthic organisms than the afterbay. A possible cause of lesser abundance of organisms is higher concentrations of iron and zinc that were found in the forebay. This study provides baseline data to help determine environmental effects of the CPE liner. Limnological studies will be continued on the forebay and Twin Lakes to determine ecological effects of pumped storage.

The available soil loss equations have been used in many grazing Environmental Impact Statements (EIS) to estimate existing soil loss and to predict soil loss due to changes in vegetative cover, but managers may place too much validity on the estimates when the differences are too small to be considered significant. Limitations of the soil loss estimates should be explained to avoid misuse in application. Universal Soil Loss Equation (USLE) estimates are generally most accurate with slope lengths of less than 400 ft and slopes from 3 to 18% having consistent cropping and management systems. Since the USLE is empirically derived, these limitations do not favor wide application to rangeland without extensive field validation. Rangeland limitations of soil loss equations can be quite extensive. Application of available erosion methodologies must be geared toward solving problems associated with resource use. The erosion model must be designed for the needed application and be sensitive to changes in manageable characteristics (those which can be affected by management actions).

A method is presented which has been used to evaluate the piping potential of shear zones crossing the foundation of a concrete dam from upstream to downstream. The method, which may also be applied to other conditions, involves determination of the critical exit gradient for the zone in question; determination of the exit gradient for the zone under reservoir conditions; and comparisons of the exit gradient under reservoir conditions to the critical exit gradient. Simple field tests can be used to determine the critical exit gradients for weak zones in concrete dam foundations. Simple calculations considering various depths of treatment concrete used to replace the weak material can be used to determine gradients under reservoir conditions, assuming uniformly isotrophic permeability and two-dimensional flow. The depth of treatment required to provide an appropriate factor of safety against piping can then be determined by comparing the critical exit gradient to calculated gradients for different treatment depths.

A 70 sq km tailing area, one of the largest in the state, is located on this river. Gold dredges appeared in California in the 1900's, and draglines were introduced in the 1930's. 1308 pebbles in 12 gravel-rich sites favorable for salmon spawning were examined by hand lens and classified into four groups: metamorphic, granitic, volcanic, and quartz. At five sites the pebble composition reflected the composition expected from upstream rocks. At five other sites the gravel composition was similar to that of the dredge tailings rather than the average composition of the water-shed or the average composition of rocks in the main and tributary canyons. Although no reliable data on pre- and post-dredging spawning conditions in the American River are available, some scientists feel that present-day spawning conditions are better than in pre-dredge times.

From October 1978 through September 1979, hourly stage and specific conductance were recorded at a station in central Shark Slough, about 17 km south of the S-12 water delivery structures. A comparative analysis of rainfall input and S-12 water delivery indicates that the study period can be subdivided into 8 hydrologic periods of differing water input character. Factors emerging as important in determining isoconductivity patterns in Shark Slough included the quality and quantity of surface water delivered to the slough, the quantitiative realtionship between the amount of surface water delivery and the amount of direct precipitation, and the effects of interrupted sheet flow within the slough during seasonal drawdown periods. The temporal trend from year to year is primarily dependent on the quality of the surface water delivered to the Slough and can be expected to continue to increase should the specific conductance and cation concentration of the delivery water continue to increase. Minimum and maximum extremes in specific conductance are likely to vary annually, depending on regional rainfall and hydrologic conditions. In a system as complex as the Everglades, it is important to maintain a continuing monitoring program both to detect any change in water quality and to differentiate between changes occurring in response to natural conditions and those produced by human actions.

In addition to the multitude of environmental laws designed to protect air and water quality, solid waste management, endangered species and cultural resources during this period, there have been several major new leasing programs covering geothermal resources , coal, outer continental shelf oil and gas, and deep seabed hard minerals. Specifically, discussion is offered on public land withdrawals including roadless area review and evaluation programs; environmental laws including the coastal Zone Management Act of 1972, the Resource Conservation and Recovery Act of 1976, water quality reviews, the Uranium Mill Tailings Radiation Control Act of 1978, air quality reviews, endangered species act, cultural resources, and state environmental law and zoning; mine land reclamation and mine safety and the mangement of minerals aquired by lease or permit. The geothermal steam act is discussed as it permits leasing of geothermal resources in federal lands. (Baker-FRC). JF - Idaho Law Review Vol 18, No 1, p 73-95, 1982. 149 Ref.

Reservoir AN - 19231920; 8206551 AB - The difference between the terms ' lake ' and ' reservoir ', which are often used interchangeably, is clarified. Lakes are natural water bodies, and reservoirs are manmade. Lakes are formed from natural processes such as faulting, volcanism, glaciation, and others, whereas reservoirs are formed by interfering with natural processes. Lakes are abundant in humid regions, but reservoirs may be built anywhere, even in arid or semi arid places as long as imported water is available. Lakes occupy closed depressions; reservoirs are open at one end and man-enclosed at the other. Most lakes are older than modern civilization, but reservoirs are relatively recent. Lakes have a longer life span than reservoirs, which are readily filled with sediments. Lakes are in harmony with the natural environment; reservoirs alter the biological communities, sometimes favorably and sometimes unfavorably. In lakes water exchange, circulation, and water levels are rather uniform. Reservoirs often have rapid releases and water level fluctuations up to 70 m (Shasta Reservoir). Lakes become more eutrophic with time while reservoirs are flushed more frequently, delaying eutrophication. Although lakes were very important economically in ancient times , the economic impact of reservoirs is now much greater.

AN - 15557601; 420684 AB - The effects of chronic exposure to simazine, an s-triazine herbicide, on the cladoceran Daphia pulex were evaluated under laboratory conditions. The daphnids were exposed to simazine concentrations corresponding to previously calculated 48-hr LC5 and LC20 values and the effects on surivival growth, reproduction, and behavior were monitored daily for 26 days. Survival of D. pulex in 20 mg/L simazine averaged 9.6 plus or minus 1.7 days. Most mortality in 4 mg/L occurred between days 21 and 25, and 65% of the daphnids were dead by day 25. Simazine interfered with molting, and growth was reduced in both concentrations tested. Reproductive maturation was delayed by about one molt cycle (3 days at 20 degree C) in D. pulex exposed to 4 mg/L simazine and was prevented in daphnids exposed to 20 mg/L. Numbers of live young and broods produced by daphnids in 4 mg/L were significantly lower than those produced by controls.

AN - 13990502; 827635 AB - Chemical contaminants and bone development were investigated in young-of-year striped bass (Morone saxatilis ) collected in spring, summer, and fall from the Nanticoke, Potomac, and Hudson rivers and Edenton National Fish Hatchery, North Carolina. Polychlorinated biphenyls (PCB) were the most prevalent organic contaminants found in striped bass; relatively lesser amounts of DDT, DDD, DDE, and chlordane were detected. Arsenic, lead, cadmium, and selenium were the major inorganic contaminants in striped bass in the Hudson, Nanticoke, and Potomac rivers. Cadmium in fish from the Hudson River, and selenium in fish from the Potomac River, increased significantly with collection date; other such correlations were not significant. Mechanical properties of striped bass vertebrae were significantly different among the four locations in both the spring and fall collections. Vertebrae from Hudson River fish had the least strength, stiffness, and toughness, and ruptured under the lowest force. Hatchery striped bass had the strongest and least flexible vertebrae.

AN - 13897827; 741167 AB - In juvenile brook trout (Salvelinus fontinalis ) challenged by applying about 10 degree virulent Aeromonas salmonicida cells to the lateral line, or held in aquarium water containing about 10 super(5) cells ml., mortalities were 50 and 60%, respecitvely, within 7 days after exposure. Neither feeding the bacterium to the fish nor applying it directly to the gills caused systemic bacterial infection. Two consistent experimental challenges developed for inducing furunculosis in juvenile brook trout: (1) 15-min contact (bath) exposures of trout to about 10 super(6) A. salmonicida) cells per milliliter of spring water, and (2) 60-s dip exposures of the fish to 10 super(9) A. salmonicida) cells per militer. These challenge procedures produced 70-100% and 74-88% mortality, respectively, within 14 days after exposure.

A method for calculating approximately such increases is given. Other usual causes of soil collapse include an increase in overburden weight when wetted during reservoir flooding and the piping of overburden by seeping reservoir water.

AN - 13786007; 652559 AB - The "gasometer" is a device that measures differential dissolved-gas pressures ( Delta P) in water relative to barometric pressure (as does the "Weiss saturometer", but operates continuously without human attention. The gasometer can be plumbed into a water-supply system and requires 8 liters/minute of water or more at 60 kilopascals. The gasometer's surfaces are nontoxic, and flow-through water can be used for fish culture. The gasometer may be connected to a small submersible pump and operated as a portable unit. The gasometer can activate an alarm system and thus protect fish from hyperbaric (supersaturation) or hypobaric gas pressures (usually due to low dissolved oxygen). Instructions are included for calculating and reporting data including the pressure and saturation of individual gases. Construction and performance standards are given for the gasometer. Occasional cleaning is required to remove biofouling from the gas permeable tubing. JF - Transactions of the American Fisheries Society AU - Bouck, G R AD - USFWS, Natl. Fish. Res.

Various trout diets were experimented in order to reduce the level of phosphorus formulated in the feed and especially to reduce the forms of phosphorus not well retained by fish. The results of the experiment are reported. JF - SALMONID.

The variance due to sampling results from the necessity of estimating areal rainfall values from point measurements of a storm footprint that contains spatial gradients. This is especially true for convective storms. Depending on how a storm passes over the gage network, the precipitation is usually either under-or overestimated. A computer model of raincell isohyetal patterns is used to assess the sampling variance. The coefficient of variation was found to increase with decreasing gage density and increasing precipitation gradient. Contrary to the sampling error studies of other investigators, it was found that the mean precipitation remained unbiased as the gage density decreased, but its standard deviation increased. The theoretical isohyetal patterns were then related to observed isohyetal maps and the characteristics of their structure. The observations suuggested a tendency for the precipitation gradient to be steepest, increasing rapidly toward the storm precipitation maximum, in short-duration convective storms of small areal extent. More uniform precipitation gradients tend to be found in steady type rains and large, long-lasting storms. Expressed in terms of the percentage of storm area containing 50 % of the precipitation volume, the precipitation gradient varied from 15 to 30%. It was also found that convective raincell patterns tended to be elliptical in shape. (Baker-FRC) JF - Journal of Applied Meteorology Vol 20, No 12, p 1468-1478, December, 1981. 3 Fig, 5 Tab, 24 Ref.

The plugging factor test is a measurement of the percent decrease in flow rate through a 0.45 micron cellulose-acetate Millipore filter membrane with a constant pressure differential of 207 KPa (gage) after 15 minutes. Several test devices are available to plant operators for monitoring the feedwater plugging factor, but their operation requires close manual attention and their results often vary in accuracy. A totally automic plugging factor monitor (PFM) was developed and tested at the Yuma Desalting Test Facility in Yuma , Arizona. The PFM tester allows selection and monitoring of water samples every 20 minutes. Resulting plugging factor calculation accuracies are within 0.4%.

One such device is a plumbline to be hung near the top of a vertical shaft within a dam. At the bottom of the shaft the movement of the plumbline can be measured, but reading by maintenance personnel on an intermittent basis does not render accurate or consitent data. A continuous reading, computer compatible, plumbline monitoring device is being developed. The plumbline position is sensed by a Kaman Model KD 2612 noncontacting, two-channel measuring system. The position data is transformed into two bipolar dc voltage outputs. An electronic interface was developed to convert the bipolar variable dc signal level to appropriate TTL (transistor-transis-tor logic) drive pulses for actuating a two axis stepper motor drive system - for an X-Y translation table. Although the interface was designed for this specific purpose, the principle of operation would be useful in any system requiring signal conversion of this type.

Simulation, using historic meteorological and hydrological data as input to the Colorado River Simulation System model, indicates that streamflow can be increased by an average of over 14%, or 1600 million cu m (1.3 million acre-ft) over a 30-year period. Furthermore, the value of this additional water totals approximately $80 million annually for the following sources: $29 million from increased hydroelectric power production, $40 million from salinity reduction, $5.5 million from water supplies to reduce deficits in Arizona and California, and $5 million from water available for new uses.

One method of calibration is that of computing an adjusted radar-rainfall field by means of the G/R ratio (gage amount divided by the sum of radar-derived rainfall throughout a rainfall event). A study was conducted to examine how much the G/R ratios would vary in an actual high rainfall-rate gradient situation considering the location and size of the radar contributing area, computation of radar-estimated rainfall using maximum, average or integrated values, and radar reflectivity factor threshold for average and integrated values. Data examined were collected on a convective shower day, June 6, 1976 at Miles city, Montana. Differences exceeded a factor of 6 and 3 were observed for individual gages and for the mean of 17 gages, respectively. Conclusions were incompleted because of the limited data set analyzed and the absence of positive truth, i.e., knowledge of the location of the most representative radar bin. Withouth a comparative analysis it was impossible to know whether improvements in G/R values will produce better rainfall estimates. If wind information is available at each gage location it may be possible to make a reverse trajectory analysis to identify the most representative radar bin for each averaging time period. If isolation of the representative radar bin is not possible, it is probably best to use either the averaging or integrating method with a reflectivity factor threshold, allowing for precipitation drift and evaporation.

As the transition from research to operation of the precipitation augmentation program approaches, public interest in resolution of the legal and policy issues increases. Social costs must be addressed first. Compensation claims can be expected for increased snow removal costs, structural damage, livestock losses, loss of use of grazing areas in late autumn and early spring, wildlife protection, and delayed access to mining areas. Rights to the additional water must be defined. Probably the most acceptable solution is to distribute extra water according to existing water rights. Since it is difficult to prove that weather modification causes damage , plaintiffs have not yet won liability suits. As more data is generated, this situation may change. A report from the Weather Modification Advisory Board favors a no-fault liability theory. The public demand for federal regulation of weather modification is likely to increase as a program becomes operational. Opposition to weather modification is affected by several factors: local differences in weather needs, occurrence of drought periods during cloud seeding efforts, lack of scientific consensus about the available technology, and lack of public participation in decision making.

Salinity levels below the dams peaked about 5 years after start of filling, then decreased. In the early years salinity was minimum during the summer months. In the later 1970 's salinity levels were nearly uniform throughout the year. Salinity variations at each dam in the series and the relationships among the series of dams are detailed. The four reservoirs in this series, which lie within phosphate-containing basins, retain 70% to 95% of their inflowing phosphorus loads. Most of this phosphorus is bound to sediment and is biologically unavailable. However, chemical reduction and in-reservoir movement release phosphorus in summer , contributing to blue-green algal blooms downstream. Key factors in determining the timing and strength of the blue-green algal bloom and the amount of reservoir which it affects depends on the location and stability of the fall thermocline.

Labeled the world 's most regulated river, it is used for irrigation, municipal and industrial purposes, hydroelectric power generation, fish and wildlife enhancement, recreation, and interbasin export. The major legislation affecting the river includes the Colorado River Compact (1922), the Boulder Canyon Project Act (1928), a treaty with Mexico (1944), and the Upper Colorado River Compact (1948). Under the Colorado River Basin Project Act, operation of the reservoirs is coordinated under these criteria: to maintain a minimum release of 8.23 million acre-feet of water from Lake Powell annually, to develop an operating plan for the river annually, and to provide all reasonable consumptive use requirements in the Lower Basin until the Central Arizona Project has been completed. When releases in excess of requirements are made, the water is put to work for power generation, leaching salts, double cropping, and extra irrigation. A salinity control act, signed in 1974, provides for removal of enough salt to make the water acceptable for delivery in Mexico. Future management of this highly complex river system must consider probable shortages and conflicts of interest among the many users.

With CRSS, proposed changes to the operation or alternative development schemes of the river system can be modeled and their effect on the future quantity and quality of water in the river may be evaluated. The CRSS comprises seven programs and data bases: CRSM (Colorado River Simulation Model); operational control data; demand data base; demand input generation program (SMDID); natural flow and salt data base; hydrology input data generation program (MHYDRO); and output summary program (TAPEDIT). The basin as presently modeled consists of 24 reaches, each of which represents a specific geographic area, and within which up to 10 inflows and 10 different demands can be identified. The model simulates river basin flows on a monthly time frame, starting at the top of the basin and proceeding to the bottom. River flows are calculated at each inflow, demand, and reservoir sequence point. With the demand data base as input, SMDID generates the demand data for CRSM, and summaries of projected depletion by water use, state, and basin.

The average ratio of tensile to compressive strength in the concrete core specimens was about 4.4%, a normal value for mass concrete. The tensile bond strength at the rock-mortar interface was less than 50% of the tensile strength of the concrete itself. Cores received with disbonded segments were not concentrated in a specific area of the dam which may indicate that there is not significant stress in a particular area. Petrographic examinations confirmed that the concrete is in satisfactory physical condition, but there is some evidence of very minor deleterious chemical alteration. These tests were done to aid in ascertaining the feasibility of raising the structure to increase flood storage capacities of the reservoir.

A computer based supervisory control system will control five pumping plants along the pipeline and a rate-of-flow control station (RFCS) to regulate waterflow. An analog computer model was designed to represent the RFCS and evaluated to determine system performance. The remote control of pipe valves was studied to ensure the system 's operation would not rupture the pipes. Because the storage tank cannot hold all the water in the pipe, the controller must ensure the tank will not overflow. These requirements occasionally require conflicting control functions. Based on this model study, the specified method of regulating terminal tank level, using a remote terminal unit actuated RFCS is expected to perform adequately. System response to transient pipe behavior is slow and substantially attenuated by large system energy transfer capacities. Proportional-integral values are critical to flow-path-control stability.

Katmai National Monument in Alaska AN - 20803402; 10903273 AB - There is a belief among managers of recreational areas that as the number of visitors increases, visitors will begin to feel crowded, and consequently their enjoyment will diminish. This belief was examined in a study of campground users at the Katmai National Monument in Alaska. It was learned that the relationship between crowding and density was mediated by personal factors (i.e., preference and expectation for density) and structural factors (i.e., spatial arrangement of camping parties, social behavior of campers, and the relationship between physical capacity of campground facilities and demand for their use). This means that managers have a variety of options to control whether or not visitors feel crowded, other than rationing policies (i.e., limiting density).

A portable system was developed for continuously monitoring the water elevation in wells by measuring the capacitance of an insulated wire placed in the water. The gage provides continuous readout, fast response to water elevation changes, and insensitivity to internal pressures. There is no effect on readings because of cascading water action. The gage can be initialized to read zero at various water elevations, and readings are not affected by water salinity. Results from a limited amount of testing indicate the feasibility of the measuring gage. The well under test had flaws in the well casing, and these irregularities of the well casing are shown in the test results. The detection of these irregularities led to speculation on other possible applications for the measuring gage in soil permeability testing and in detection of fractures in concrete and rock. Three methods for groundwater measurement are possible using this instrument: measurement of well discharge by water withdrawal or by disperson using air pressure in the well casing; measurement of the recharge rate after withdrawal of water; and measurement of the water elevation of normal conditions.

With rising fossil fuel costs making the low-head sites more attractive economically, it is desirable to determine possible design changes to lower construction costs without producing significant head losses. Flow passages for low-head hydropower development cannot be standardized because of structural and geological differences and fish passages. However, where geological and structural considerations are similar, the same design may be used for a series of installations, reducing engineering and design costs. The possibility of shortening draft tubes (responsible for 30% of civil costs) using boundary layer control is explored. No research in this area has been done on hydraulic turbines. Intakes may probably be reduced in size or simplified in shape without losing efficiency because flow volumes are low. An example is the use of flat surfaces to approximate curved surfaces. Many hydraulic structures were designed with the demands of high flows and pressures experienced in high-head systems. Since low-head systems do not exert these severe demands, it is possible that equipment can be simplified.

The theory states that a system is in equilibrium when its rate of energy dissipation is at a minimum. When a system, such as a river, is subjected to constraints, it adjusts itself until it approaches the equilibrium conditions. The calculated exponents (width, 9/22; depth, 9/22; and slope, -1/6) of the hydraulic geometry relationships proposed by Leopold and Maddock (1953) agreed very well with those measured in the laboratory by Barr et al. (1980). The theoretically derived hydraulic geometry exponents also agreed with observed values from natural river gaging stations. Channel depth can be readily adjusted in accordance with the minimum rate of energy dissipation theory, but width adjustment may depend not only on discharge and sediment load, but also on past history of the river, erodibility of the bank, valley width, vegetation, and man-made structures and improvements.

This processor allows the Bonneville Power Administration to receive the actual plant total power generation with minimal delay, thus allowing EPA to implement AGC control of Grand Coulee. As an added benefit, the CASS processor derives and sends to the Grand Coulee programmable master supervisory control a value for substitute generation which relieves the operator of the duty of manually entering changes in substitute generation. The theory, operation , and program flow charts for the new microcomputer control system are presented. The AGC system should prove more predictable and stable as a result of this installation.

The study period included two years of severe drought followed by two of higher than average runoff in the North Platte basin. The reservoirs differ greatly in volume and operating patterns: Seminoe is mainly for power production; Korte and Alcova, for flow regulation, and Pathfinder for storage. The three major system tributaries, the North Platte, Medicine Bow, and Sweetwater Rivers, differ significantly in chemical composition and annual flow volume. Limnology of the Upper North Platte reservoir system is typical in many ways of the High Plains Region; the reservoir waters are dimictic and alkaline, with salinity averaging 369 mg/1 and calcium carbonate hardness averaging 184 mg/1. Also the bluegreen alga, Aphanizomenon flos-aquae, blooms in late summer. Study results showed that this annual bloom depends on a shift from phosphorus-limiting conditions in early summer to more nitrogen-limiting conditions by late summer. Nutient dynamics, and hence primary production in the system, is heavily influenced by the interaction of three main factors: system operating criteria, annual runoff variations in the three major tributaries, and the presence of deep outlets in all four dams.

Induced sinkholes are divided into two types: those resulting from a decline in the water table due to groundwater withdrawls and those resulting from construction. Most induced sinkholes occur where cavities develop in residual or other unconsolidated deposits overlying openings in carbonate rocks. Thd downward migration of the deposits into underlying openings in bedrock and the formation and collapse of resulting cavities are caused by a decline in the water table resulting in induced recharge and other changes in groundwater movement. Most sinkholes from construction are related to the diversion of drainage over openings in bedrock.

Seventeen subsidence areas in the United States are identified and described. Subsidence ranges from 0.3 m at Savannah, Georgia, to 9.0 m in the San Joaquin Valley in California. Principal problems caused by subsidence are: (1) differential changes in elevation and gradient of stream channels; (2) failure of well casings due to compaction; (3) tidal encroachment in coastal areas. Subsidence develops under either carbonate substrate overlain by unconsolidated material, such as sinkholes, or in porous semiconsolidated sediments laid down in lacustrine environments. Both types of subsidence occur in the United States.

The model is described by a continuity equation, a discharge-stage relation (stream rating), and a stage-storage relation (reservoir configuration). The infiltration loss in the stream channel is analogous to leaking in the bottom of a reservoir. No input is routed through the reservoir: at the onset of the recession the reservoir has water in storage. By calibrating reservoir leakage rate and initial storage (reservoir shape) a good fit to observed curves is obtained. The most critical parameter is reservoir shape; recession curves do not change much with changing reservoir loss rate.

A buried pipe is a structure that incorporates both the properties of the pipe and the properties of the soil surrounding the pipe. The installation requirements include the right type of soil and depend on the type of pipe - rigid or flexible - the diameter of the pipe, and the special case of PVC pipe. Specific installation instructions are given on the type and distribution of soil, including the foundation, bedding and backfill, and the achieving of soil-pipe contact. Correct trench dimensions are required for each type of pipe and depend on the type of soil. Density tests are conducted to ensure correct soil density. Elongation and deflection are generally problems of flexible pipes and allowable net deflections have been established. Specific instructions are given for the installation of small diameter pipes (10 in or less) and PVC pipes.

The 1:80-scale spillway model included the approach channel, spillway, outlet works, powerplant, and downstream river channel. The model showed that excavation was not necessary in the spillway approach channel. A discharge curve and gate opening combinations were derived from the model. The flow over the crest was satisfactory with the piers shortened; however, it impinged upon the gate trunnion pins at higher discharges. On the spillway chute, all offsets greater than 3 mm should be ground to a 1:10 chamber. The stilling basin walls were over-topped for discharges greater than 2300 cu m/s; however, pressures indicated that they would remain stable. The velocities downstream of the stilling basin were within the design range; however, the riverbed eroded for about 24 m downstream of the apron. The 1:50.65-scale outlet works model included two 9-m-diameter concrete-lined tunnels with intakes for either diversion flow or for flow through the penstock and permanent outlet works. The model provided discharge information for the uncontrolled diversion flow and the gated permanent outlet works. Flow through the tunnel bends and velocities downstream of the stilling basins were satisfactory. No erosion occurred downstream of the outlet works or the powerplant. The penstock intake with the trashrack installed passed all discharges without vortices being formed. JF - Report GR-81-9, June 1981. 83 p, 61 Fig, 13 Tab.

During the 1930's, radial gates were installed on both spillways to provide extra reservoir storage. The spillways were cut into each abutment with each spillway crest oriented to continue the arch shape of the dam. This alinement creates many problems because the south spillway channels its flow directly toward the upper right training wall instead of downstream. During a flood in February 1980, the spillways operated with a combined discharge of approximately 73,500 cu ft/s. The south spillway overtopped the right training wall, cascaded down the slope, and entered the powerhouse. A downstream training wall that protected the highly jointed canyon walls from erosion was damaged, and a converted warehouse was also damaged by mud and water entering the lower floors. A 1:36 scale model was used to develop protective measures for this powerplant, the highly jointed downstream canyon wall, and other structures. Also determined from the model study were spillway and radial gate discharge capacity curves. The model showed that a 15-ft high extension to the right training wall would provide full protection for the powerhouse. A 200-ft long wall was found necessary to provide adequate protection for the lower canyon wall. An extension to this wall, angled toward the river channel , was also recommended to protect the warehouse. (Moore-SRC) JF - Report GR-81-10, May 1981. 41 p, 24 Fig, 1 Append.

These studies were conducted in the Coachella Valley Water District and the Imperial Irrigation District in southern California. Baseline data were collected on hydrophyte distribution, biomass, and density; root and rhizome biomass; tuber density; and soil composition. In the Coachella Canal, the dominant hydrophyte, Myriophyllum spicatum, was sparse in April, but increased in biomass in each test section throughout the growing season. The hydrophytes in the Wormwood Lateral 3 varied considerably between the test sections. In April, the dominant hydrophyte, Hydrilla verticillata, was sparse throughout the lateral, but by July it had reduced the water-carrying capacity in one section by 50%. Other sections in Wormwood Lateral 3 remained low in biomass throughout the season, with the exception of one section which was dominated by Potamogeton pectinatus and Najas guadalupensis from October through November. The most promising parameters for evaluating the sterile hybrid carp efficacy will likely be hydrophyte biomass, areal coverage, and estimates of relative abundance.

The model was also used to study spillway gate sequencing for low discharges, overtopping of the five center bays of the buttress dam during flood discharges, and calibration of the free flow and gate-controlled spillway discharges. The initial topography which resulted from the March 1978 spillway discharges, and two proposed plunge pool design modifications were tested in the model. Based on impact pressure data and visual observations, the Concrete Dams Section staff designed a concrete mat to prevent further upstream erosion of the rock at the base of the spillway chute. An operational procedure was developed for spillway gate sequencing to prevent overtopping of the left training wall during low discharges. The sequencing of gates was also studied to deflect the flow away from the right side of the plunge pool during repairs in 1979. Two river channel modifications downstream from the plunge pool were studied in the model. To pass flood discharges greater than 6031 cu m/sec, the five center bays of the buttress dam will be overtopped. JF - Available from Engineering and Research Center, Denver CO.

Maximum water temperatures were recorded in August 1980 and were about 17 and 18 C for the upper and lower lakes, respectively. The lowest measured dissolved oxygen concentration was 1.3 mg/l at the bottom of the lower lake in October. The pH ranged between 6.3 and 8.3, and the conductivity levels were between 64 and 90 micro S/cm. Total phosphorus concentrations never exceeded 2 micro g/1 during 1980, while nitrate nitrogen ranged from less than 10 to 90 micro g/1. Average daily primary productivity rates ranged from a low of 1.6 mg C/ (sq m/d) in the upper lake during January to a high of 143.5 in the lower lake during November. Chlorophyll a concentrations ranged from 0.6 mg/cu m below 14 m in the lower lake during April to 18.0 mg/cu m near the bottom of the epilimnion in the upper lake during September. Average phytoplankton and zooplankton densities reached maximum of just over 13,000 and 125.8/L, respectively, during August in the lower lake. Phytoplankton populations were dominated by diatoms and dinoflagellates, while zooplankton populations were dominated by copepods, oppossum shrimp, and rotifers. The benthos of Twin Lakes is dominated by chironomids, oligochaetes, and fingernail clams reaching maximum densities respectively of 2922, 800, and 974/sq m in the lower lake, and 1969, 2813, and 173/sq m in the upper lake.

A minimum annual flow rate of 260,000 acre-feet into the park has been mandated, and, because of the slough dimensions and low hydraulic gradients, new techniques for discharge and distribution were required. A tracer dye was used in conjunction with Landsat imagery to determine sheet flow rates, spatial distribution and volumetric storage. Velocities of 0-0.035 ft/s were measured, below the detection limits of conventional instruction. When coupled with cross-sectional area calculations, a reasonable estimate of the slough 's contributions to the estuarine region was 200-2000 cu ft/s. Freshwater distribution within the slough was subject to seasonal inundation fluctuating between 90,000 - 245,000 acres, providing storage estimates between 26,000 - 208,000 acre-feet for the dry and wet seasons, respectively. Such shifts in available surface water play a significant role in driving the productivity of the Everglades ecosystem.

Protection ranges from almost complete protection in the first parks established to almost no protection in the most recently established parks. Coral reef ecosystems are dynamic and change dramatically in response to natural short-term environmental variations such as unusually low temperatures. Fisheries harvests may reduce the size at which exploited species mature, and reduce the amount and variability of genetic material produced by exploited populations. The consequences of permitting consumptive uses of aquatic resources in parks and preserves need to be evaluated. Natural areas must be protected to serve as standards which will allow distinctions to be drawn between effects of exploitation or pollution and normal variation. Unless consumptive uses are severely limited, the primary values of parks and reserves may not be realized.

A combination of nutrient loading models and a temperature simulation model were used to project the trophic state, productivity, and duration of stratification of the reservoir. The trophic state index indicated that the reservoir would be eutrophic; the estimated mean annual chlorophyll a concentration indicated a high likelihood that algal blooms would occur. A classification function was applied to the reservoir to evaluate whether the blooms would consist of blue-green or nonblue-green algae. The results show a 98% probability that blue-green algal blooms will occur. Dissolved oxygen curves for the reservoir were then developed for the period immediately prior to fall overturn. Curves were developed based on a reservoir with similar nutrient loadings and on theoretical curves. From these and the temperature model, oxygen concentrations in the reservoir discharge were estimated. The dissolved oxygen may be sufficient to support aquatic life but may fall below the Nebraska standard under certain circumstances. The reservoir and the river downstream are expected to support a cold-water fishery; most species now present in the river will be eliminated. The methods developed for this study may have application to other impoundments where an analysis is required to answer questions concerning the potential for such problems.

The RMPP would potentially cross many intermittent and perennial streams. The major concern with a pipeline stream crossing is the disruption of the streambed and the increase in sediment movement. The distance that the construction-induced sediment would be transported depends upon construction techniques, the stream flow parameters, and the grain size distribution of the stream bed materials. The disturbance of the streams cross section and the increase in sediment would be short term (3 to 5 days). It is expected that the levels of contaminants, such as lubricants and fuels introduced by construction into the waters that are crossed, will exceed state standards for short distances downstream, and mixing will be rapid. At some stream, road, and utility crossings and in some other topographically low areas, ground water may be encountered, but effects on groundwater would be localized and temporary. The proposed pipeline system would cross a floodplain at every stream crossing, but no aboveground permanent facilities would be constructed within a 100-year floodplain. Since regulations require that the pipeline be buried below the maximum scour depth, there would be no effects on flood stage. The pipeline will be hydrostatically tested in sections. The test water will be discharged in an environmentally acceptable manner.

The high salt content and moderate flow rates significantly contribute to the salinity of the Colorado River. Methods were evaluated for preventing high salinity LVS water from entering the Virgin River and for utilizing the process water in energy development. Analytical water data obtained from a 9-month test program at LVS test site were evaluated. The raw water typically contains 750 mg/l of dissolved carbon dioxide and has a pH near 6.0. It contains the following concentrations in mg/l: 820 of calcium, 150 of magnesium, 1266 of bicarbonate, 1860 of sulfate, 2220 of sodium, and 3345 of chloride. The raw water contains significant amounts of silica, boron, strontium, and sulfide, and a measurable amount of radioactivity. The relative merits of different methods of treatment, disposal, and reuse of LVS water were studied. The disposal of water by deep well injection, use as a secondary coolant in a binary cooling tower, use in solar salt-gradient ponds, and use as a transport media for coal slurry pipelines was found to be technically feasible. Use of LVS water to transport coal to a consuming powerplant and subsequent reuse in a binary cooling tower or solar salt-gradient ponds would achieve both objectives of salt reduction and energy conservation.

During a heavy runoff of water in 1973, operators reported large quantities of sediment passing through the headworks and tunnel. Sediment passing through the Blanco Tunnel headworks travels through about 40 km of tunnel. A 1/16-scale sediment model was used to study proposed modifications of Blanco Diversion Dam. Pit-run sand was used to simulate bed sediment sizes ranging from cobbles to fine sand, including sizes in the coarsest 7% part of suspended sediment samples. The model was verified with hydrologic estimates and field data. Tests were directed toward keeping coarse sediment out of the headworks, making sluicing of sediment less troublesome to down-river water users, reducing trash problems on the headworks rack, and keeping sediment from interfering with downstream water measurement. A three-part sequential trap system in front of the headworks was developed. This system uses sluicing over successive trap walls and reduces the amount of sediment entering the tunnel to about 19% of that entering the existing system during 1971 to 1975. At lower river flows, the traps reduced the grain size of the sediment entering the tunnel to 1/20 that of the riverbed material, and at higher riverflows the reduction was to 1/5 that of the riverbed material.

Such covers are also needed on most membrane type linings provided for seepage control to hold them in place, protect them from exposure to the elements, and prevent damage to the membrane. The characteristics and observed stability of fine and coarse soil cover layers placed on 19 selected earth-lined and unlined canal reaches to resist water erosion and to protect asphalt and plastic membrane linings are reported. Soils which have generally performed well in coarse cover layers on canals with tractive forces less than 5 N/sq m have contained: maximum particle sizes between 75 and 150 mm; less than 50% passing a No. 4 sieve, and less than 10% passing a No. 200 sieve. Predominantly medium to coarse sand in the fine layer may cause the coarser layer to be unstable during canal filling and drawdown. Some cover soils placed loosely without moisture or density control will settle when water is introduced into a canal and cause cracks to form. In cold climates, freezing of soil moisture drawn to the underside of a membrane lining may cause sliding of the membrane on the subgrade during periods of thawing.

Proposed alternatives include: no action: a 10-year program, with an initial 5-year phase for tests in two subbasins followed by a 5-year randomized seeding program; an 8-year program in which the initial phase is reduced to 3 years; and a 6-year program with a 2-year initial phase followed by a 4-year second phase. In each of the cloud seeding options, the initial phase involves installation of meteorological and hydrological observation and data collection networks. Seeding opportunity, climatological studies, seeding mode studies, and ground-based seeding studies would be included in the initial phase for the 10-year and 8-year options. No significant impact is expected from the initial phase. Each of the three cloud seeding options includes a second, randomized demonstration phase. An operational winter cloud seeding program could result in a 10 to 15% percipitation increase. Avalanche conditions and flood hazards will be included in suspension criteria for this project. It is expected that the use of seeding agents in this precipitation management research will have no environmental impact. A Finding of No Significant Impact for the Design Phase of the Colorado River Enhanced Snowpack Test is included. (Moore-SRC) JF - Report, April 1981. 39 p, 1 Fig, 18 Ref.

This plant would provide drainage water treatment for the Wellton-Mohawk Irrigation and Drainage District. The plant would subsequently reduce the salinity of Colorado River water delivered to Mexico. The instrumentation requirements for the test facility include monitoring the plugging factor of the water at various points in the water pretreatement process. The measurement of this factor is used to indicate the amount of organic and inorganic particulate matter which is suspended in the water. To automate the measurement process, a controller was needed for the measuring device. The function of the Plugging Factor Monitor Electronic Controller is to provide plugging factor measurements on any or all of the six possible sample streams. The Plugging Factor monitor can be incorporated into any water treatment facility where the measurement of a plugging factor is required.

For many of the species occurring in Alaskan arctic areas, long-term, chronic, and direct or indirect effects associated with oil and gas development are of greater concern than the probability of widespread direct affects on seal populations. One possible result of low-level or chronic pollution would be to contribute to physiological stress on marine populations which may be at or near carrying capacity. Indirect effects of oil pollution on marine mammals would be those associated with changes in availability or suitability of various food sources or essential habitat factors. Mammalian species such as bearded seal or walrus may be most likely to show tropic-related effects in a specific locale since they rely on relatively sedentary benthic food sources. Shock waves and noise disturbance associated with offshore oil and gas development may alter the behavior of marine mammals. Other factors which may directly affect marine mammals include shoreline alteration, facility siting, dredging and filling, and secondary development. Potential factors affecting endangered cetaceans include direct and indirect oil and gas pollution effects, noise and disturbance effects and other factors such as marine disposal of drilling muds, formation waters, and cooling waters, shoreline alterations, and airborne noise.

Many of the most common seabirds in Alaska and species endemic to the Bering Sea or the North Pacific are highly sensitive (a score of 70 or greater OVI) to oil pollution. The southern Bering, northern Bering, and the Chukchi Sea regions have over 80% of their major seabird colony populations rated highly sensitive. Within the Gulf of Alaska, the northwestern region and southwestern region have substantially larger populations of sensitive birds than the northeastern region. In general offshore oil and gas development in the Bering Sea poses a greater risk to seabird and waterfowl populations than would oil development in the Arctic Ocean or in the Gulf of Alaska. Oil and gas activities within the major foraging habitat of vulnerable populations in the Bering Sea represents the greatest concern to seabirds in Alaska. For most endemic waterfowl populations, the Yukon-Kuskokwim Delta represents the most important or critical habitat in Alaska.

Elbert Forebay Reservoir AN - 18950954; 8300641 AB - During the summer of 1980, approximately 117 ha of 1.14-mm CPER (reinforced chlorinated polyethylene) flexible membrane lining was installed in the Mt. Elbert Forebay Reservoir. The forebay reservoir and the Mt. Elbert Pumped-Storage Powerplant are part of the East Slope Power System of the Fryingpan-Arkansas Project. The installation constitutes the world 's largest single-cell flexible membrane lining application to date, and is the first time that such a material has been used in a pumped-storage reservoir for seepage control. To meet the requirement for power online for the powerplant by July 15, 1981 , the installation had to be accomplished in one construction season. Efficient handling and processing of earth materials were the keys to completing the job on schedule. The QA (Quality Assurance) Program was very effective. Probably the most valuable part of the QA Program was the field inspections, both factory and jobsite. The seam peel strength test for factory and field seams provided important information as to seam quality. Air lance testing proved to be a quick and effective method for checking the bonded overlap of seams. Field cutout samples proved to be a good check on the quality of the field seams.

Physical and chemical water parameters were measured, aquatic macroinvertebrates were collected, and fish populations at selected stations were evaluated to determine density and heavy metal content of tissue. Historically, river flows which dilute heavy metal concentrations were not as high as those occurring since transmountain diversions began, so it is possible that heavy metal concentrations in the river were greater in the past. However, water quality, species diversity of aquatic macroinvertebrates, fish populations, and metal accumulation in fish tissue show that heavy metal pollution of the upper Arkansas River near Leadville, Colorado, is presently very severe. Conditions for aquatic life are generally poor even though physical parameters and major ion concentrations are adequate for the survival of most aquatic organisms. Heavy-metal-laden inflows adversely affect water quality and thus the aquatic animal populations, while freshening inflows improve water quality and, therefore, conditions for the aquatic fauna. The major sources of heavy-metal-laden inflows are the Leadville Drainage Tunnel, California Gulch, and a number of intermittent flows entering between Lake Fork and Lake Creek. Important freshening flows are Tennessee Creek, Lake Fork (containing Halfmoon Creek), and Lake Creek. It is highly probable that a substantial reduction or elimination of any of these freshening inflows will result in a degradation of water quality and adversely affect the aquatic organisms.

Possible modifications to minimize downstream channel erosion, and optimize flow conditions in the approach channel were investigated. The model included the approach channel, spillway crest and radial gates, spillway chute, combination stilling basin - flip bucket, and exit channel. The 18.3 m wide by 303 m long chute spillway is designed for a maximum discharge of 940 cu m/s. Ordinarily, energy is dissipated in a hydraulic jump. For large floods, the flow will sweepout of the stilling basin into the exit channel. Model studies included investigation of approach flow conditions , pressures and flow distribution in the chute spillway, flow characteristics with the combination stilling basin-flip bucket, and flow conditions and erosion in the exit channel. Four flip bucket configurations were tested. In the final design, the radius of the flip bucket was shorter and the lip elevation higher than in the original design. These changes helped stabilize the hydraulic jump and clear the jet impact away from the basin after sweepout with a minimum amount of damage to the downstream channel. The discharge channel was deepened and widened to dissipate the energy of the jet striking the tailwater after sweepout. The initial sweepout flow is 465 cu m/s, as compared to the 100-year flood of 375 cu m/s. The outlet works can pass an additional 145 cu m/s. A spillway flow of 200 cu m/s is required to wash 75 mm diameter rocks out of the stilling basin. (Moore-SRC) JF - Report GR-81-2, March 1981. 56 p, 26 Fig, 2 Tab, 5 Ref.

For compacted soil canal linings, laboratory and field test results show that under certain soil and temperature conditions, freezing decreases soil density near the surface, but increases density at depth. In two linings, the average density increased slightly during a 20-year period. Frost penetration measurements made during the 1978-79 winter on a 1.5-m-thick reservoir lining, on three earth dams under construction, and on the Teton Dam remnant are shown along with associated soil conditions, air freezing indexes, and insulating effects of snow and, for one dam, a loose soil cover. There is a discussion of (1) frost penetration in different types of soil with and without gravel particles, (2) the effect of freezing on soil near the surface of partially completed earth dams during winter shutdown periods, (3) the need for investigating frost conditions in preparation for resumption of embankment placement in the spring, (4) a suggestion of possible detrimental freezing action at the interface between a rock abutment and an earth embankment, and (5) the possibility of crack formation caused by soil shrinkage during freezing action.

Concrete core evaluation programs are also conducted at various ages on major dams. This report presents test results on concrete cores taken from Morrow Point Dam up to 10 years ' age. The physical properties tests conducted on 250-mm(10-in) diameter cores at 60 days, 180 days, 1 year, 5 years, and 10 years indicate that overall condition of the concrete is good. The thin-arch design used at Morrow Point required a higher than normal compressive strength for mass concrete. Most mass concrete dams built previously contained interior and exterior mixes; however, with the higher compressive strengths maintained at Morrow Point, a single mix was sufficient for the entire structure. The compressive strength of the mass concrete at 10 years averaged 51.6 MPa (7,480 lb/sq in). Also at 10 years, the modulus of elasticity and Poisson 's ratio averaged 35.1 GPa (5,090,000 lb/sq in) and 0.24, respectively. The tensile strength of all cores tested at 10 years averaged 1.59 MPa (230 lb/sq in), which is comparable to tensile strengths for other Service dams.

The dominant algae continued to be diatoms, as previously reported in 1976 and 1978. These diatoms are known to be predominantly epiphytic forms that grow on the canal lining and other substrate, and are torn loose by waterflow and become free-floating plankton. Algal cell counts over this period ranged of approximately 4,500 cells/mL in January 1980 to a maximum count of approximately 45,000 cells/mL in April of 1979. The measured drift was predominantly aquatic weeds, filamentous algae, and terrestrial debris, averaging approximately 2300 kg wet weight per 24 hours with a maximum of approximately 6000 kg per 24 hours. Environmental parameters in the drainwater, such as the nitrogen and phosphorus levels, were studied. A combination of conditions appears to be responsible for changes in aquatic vegetation productivity. The data indicate that removal of weeds by maintenance is directly related to the amount of vegetational debris found downstream. These biological data were used in part to aid in the design and development of operating criteria for the 394000 cu m/day desalting plant to be sited on the canal as part of the Colorado River Basin Salinity Control Project.

In 1977, the Office of Water Research and Technology (OWRT) of the U.S. initiated its Water Reuse Research and Development Program by conducting a comprehensive national analysis of reuse and potential throughout the U.S. This study indicated that a high potential for both municipal reuse and industrial recycling exists in the U.S. The OWRT also evaluated existing treatment technology for applicability in reuse systems. The role of state agencies in implementing an effective wastewater reuse research program includes determining wastewater reclamation research needs, assessing the status of world-wide wastewater reclamation research, establishing a list of high priority research areas for funding priority, and working cooperatively with federal agencies involved in water reuse. Projects involving beneficial reuse of wastewaters that result in reduction of wastewater discharges and utilization of nutrients, organic materials or pollutants should merit funding support at least equally with single purpose pollution abatement projects.

AN - 15534085; 376377 AB - Acute and chronic toxicity studies were conducted with fathead minnows (Pimephales promelas ) and the organochlorine insecticides Kepone and mirex. Kepone was highly toxic to fathead minnows under acute conditions: 96-hour LC50's (median lethal concentrations; 95% confidence limits in parentheses) were as low as 340 (289-400) mu g/liter and 96-hour EC50's (median effective concentrations; 95% confidence limits in parentheses) were as low as 18 (15-22) mu g/liter. Accumulation factors (toxicant concentration in fish tissue divided by toxicant concentration in exposure water) were 1,100-2,200 for Kepone and 12,000-28,000 for mirex, although tissue residues of mirex continued to increase through 120 days of exposure. Tissue residues of Kepone were below detection limits after 7 days of elimination, while 46% of the mirex residues remained in fish after they were held 56 days in mirex-free water.

AN - 15531653; 375576 AB - Cutthroat from Salmo clarki were exposed for 90 days to four concentrations of a Wyoming crude oil in water, ranging from 100 to 520 mu g/liter. Survival was reduced to 52% among fish held in the 520- mu g/liter concentration, but was not affected by three lower concentrations. The growth of cutthroat trout in all four concentrations was significantly slower than that of the control fish. Accumulation of total hydrocarbons in fish tissue was directly related to water concentration, except for fish in the 520- mu g/liter concentration. Alkylated mono-and dicyclic aromatic hydrocarbons were accumulated most readily and naphthalenes were the dominant aromatic component in oil, water, and fish. Evidecne from this research suggests that discharges of 10 mg/liter oil and grease allowed by several western states are too high.

AN - 15531302; 376270 AB - A model based on empirically derived age-, time-, and space-variant entrainment susceptibility data may be used for estimating conditional entrainment mortality of aquatic organisms, particularly fish and shellfish, caused by operation of one or more power plants on an estuary. Model application requires knowledge of the morphometry of the water body, the power-plant flow rates, the probability of entrainment survival, and the duration, distribution, and abundance of entrainable age-groups. A novel feature of the model is that organism distribution and movement within the model are defined by information derived from field samples rather than by hydrodynamic principles and equations.

AN - 15530964; 376388 AB - Juvenile coho salmon (Oncorhynchus kisutch ) production (tissue elaboration) was monitored in 12 laboratory streams under six replicate treatment levels of fine sedimentation. Increasing sedimentation suppressed fish production. Our data confirm that habitats of salmonid juveniles, as well as spawning areas, should be protected against fine sediments. Substrate Score, a visual technique for evaluating stream substrate quality, correlated closely with both the geometric mean particle size of the substrate and fish production, and can be easily applied in the field.

AN - 15530734; 376186 AB - Shoreline fish populations from five areas in Keowee Reservoir, South Carolina, were sampled with a bag seine from June to September, 1973-1978, to determine the effects of electrical power production on fish distribution and abundance. Significantly ( alpha = 0.05) more spottail shiners (Notropis hudsonius ) were in the heated discharge of Oconee Nuclear Station than in the other four areas; they were first collected there in 1975, and by 1977 were the most abundant species in this area. Spottail shiners also increased annually in other areas, but abundance decreased as distance from the heated discharge increased. Increases in water temperature and abundance of macrophytes paralleled increases in the abundance of spottail shiners and appear to be the most important factors regulating the distribution and abundance of this species in Keowee Reservoir.

AN - 15524651; 363997 AB - The biochemical effects of Kepone and mirex on bone development and swim bladder composition in fathead minnows Pimephales promelas were investigated in chronic toxicity studies. Continuous exposure of fathead minnows to Kepone (0.013-0.31 mu g/liter) or mirex (2-34 mu g/liter) to the alteration of collagen and vitamin C metabolism within 30 days. Kepone concentrations of 0.17 and 0.31 mu g/liter reduced collagen metabolism in the backbone after 120 days of exposure. Both mirex ( greater than or equal to 3 mu g/liter) and Kepone ( greater than or equal to 0.31 mu g/liter) decreased hydroxyproline concentration in the swim bladder. Acute exposure of fathead minnows to Kepone did not affect the chemical composition of vertebrae, even though scoliosis and vertebral damage were observed. Thus Kepone can induce vertebral damage in two ways: acutely by causing muscular contractions; and chronically altering vertebral collagen metabolism.

AN - 15504940; 327191 AB - Alewives (Alosa pseudoharengus ) were reared from the egg to the early juvenile life stage. The major obstacle to rearing alewives from the egg -- providing an acceptable food that facilitates first feeding -- was overcome by presenting a mixture of wild zooplankton to the larvae twice daily, beginning on the day of hatching. Initial feeding by larvae held at 20 degree C was observed 2 days after hatching, when the yolk was nearly absorbed. Comparison of stomach contents and the wild zooplankton composition suggested that the diet of larvae during the first 15 days of life shifted with changes in the availability of food but remained within a fairly narrow range of food sizes. Larvae hatched at a mean total length of 3.8 mm and grew at an average rate of 0.62 mm per day, to a mean of 35.5 mm after 50 days.

AN - 15422488; 241243 AB - The authors have experimented the addition of cement kiln dust (CKD), which originates from the coal burned during cement manufacture, to the diet of rainbow trout, Salmo gairdneri , to determine its effect on weight gain, mortality and selenium accumulation in the liver. As judged by the lack of pathology and good diet acceptability in this brief test, it appears that if CKD has application in fish diets, it might be as a pellet binder.

Slevin written during the expedition of the California Academy of Sciences to the Galapagos Islands in 1905-1906 contain previously unavailable data on the marine turtles of the eastern Pacific. "Land basking" by green turtles in Galapagos was predominately, if not exclusively, a female behavior. These terrestrial emergences were not concentrated in the major reproductive season of Galapagos turtles. Female Chelonia were also collected on shore during daylight hours on Socorro Island southwest of Baja California, Mexico. Chelonia mydas green turtles, were observed to feed on seaweed, the leaves and shoots of mangrove trees, and the leaves of another unidentified shoreline shrub. Comparative data on the gonads of dark and yellow turtles indicated that the latter did not breed in Galapagos during Slevin's stay. Lepidochelys olivacea , the olive ridley, was recorded in Galapagos waters and fed on fish eggs. JF - Journal of Herpetology AU - Fritts, TH AD - USFWS, Denver Wildlife Res. Ctr., Tulane Univ.

A chestnut-oak forest unit, which occurs on metavolcanic rocks and some metaclastic rocks in the western Piedmont and on highly weathered upland gravel deposits in the eastern Piedmont, can be discerned on a digitally enhanced Landsat winter image. The image enhancement procedure consists of a principal component transformation, a histogram normalization, and the inverse principal component transformation.

Partial fractionation is best accomplished with 1NHCL. Statistical analysis within specific subsets of data indicate trace metals are partitioned among several substrates in most sediments, the substrates compete with one another for the metals, and the outcome of the competition is strongly influenced by the concentrations of the different substrates in the sediment.

AN - 13703558; 571181 AB - Precipitation in Europe and eastern North American has become acidic, a result of increases in sulfuric and nitric acid aerosols produced by fossil-fuel combustion, metal smelting, and industrial processes. Some metals and organic compounds also are transported atmospherically and deposited in acidic precipitation. In regions where acid neutralizing capacity of soils and water is low, the pH of lakes and streams has decreased and concentrations of metals have increased. Aquatic organisms have been affected in all trophic levels abundance, production, and growth have been reduced and sensitive species have been lost. Fish have suffered acute mortality, reduced growth, skeletal deformites, and especially reproductive failure. Valuable commercial and recreational fisheries have been lost in certain areas and such losses will become more widespread if acidic precipitation continues. Remedial or mitigative actions directed toward the problem include hatchery production of acid-tolerant fish and chemical neutralization of selected lakes and streams. The ultimate solute is reduction of the sources of atmospheric acid. JF - Transactions of the American Fisheries Society AU - Haines, T A AD - USFWS, Univ. Maine, Columbia Natl. Fishereis Res.

AN - 13575700; 457007 AB - A study was undertaken to determine whether the bonytail chub (Gila elegans ) could hybridize with the roundtail chub (G. robusta ) and the humpback chub (G. cypha). Of 12,000 bonytail x roundtail hybrids and 8000 bonytail x humpback hybrids obtained, 7 months after hatching, some 500-1000 from each cross survived. Embryos in eggs of both crosses died after 110 hours in low temperatures, indicating a possible reason for the decline of this endangered species in the upper Colorado River Basin. Both hybrids failed to spawn naturally, but it is suggested that alterations in the upper basin of the river may increase the potential hybridization and the decline of genetically pure stock.

AN - 13575468; 456969 AB - Tests with first-feeding fry of fall chinook salmon (Oncorhynchus tshawytscha ) were conducted to evaluate diets containing 3 levels of protein (50, 53 and 56%) at 2 available energy levels (345 and 365 kcals/100g diet). Results showed that both growth and survival were significantly affected by the dietary protein and energy levels when the fish were reared in cold creek water but not when reared in warmer well water. The inference that survival may be influenced by the energy content in diet, thus is of importance in the formulation of practical diets.

AN - 13565443; 456762 AB - A study was undertaken to describe the fecundity of the black crappie (Pomoxis nigramaculatus ) in Keowee Reservoir, South Carolina, USA, and also to determine whether it was affected by the elevated water temperature resulting from the discharge of heated water from a nuclear water plant. Fecundity was significantly correlated with length and weight but not with age. It was apparently unaffected by the temperature alterations in the reservoir due to the plant; the fish may have evaded any unfavourable water temperatures (if any) by moving about, thus avoiding severe physiolgical stress which could result in a change of fecundity.

In 1929, a shear crack , caused by a thawing ice sheet, developed in the overflow spillway and the danger of cracking in the spillway remains a concern. Repairs were performed, but the displaced crest was not moved back into place. There apparently has been little or no differential movement since the repairs. Compressive strength tests indicate the strength is significantly higher than the probable design strength. Elasticity test results show a large variation in the moduli of elasticity and Poisson 's ratio, probably due to volcanic stone in the concrete. Absorption varied from 2.7 to 6.1%. There was little variation in density and a wide variation in tensile strength. The average shear strength at normal load was 3.0 MPa and seemed reasonably high through intact construction joints. Alkali-silica reaction is the main chemical deterioration observed in this concrete. Petrographic evidence and physical properties indicate large variability in concrete quality.

A systematic procedure was used to organize, classify, summarize, integrate, and synthesize the baseline data into categories of key ecosystem components and processes. The operator 's detailed development plans for the oil shale were used to identify anticipated perturbations to the ecosystem. These prturbations were integrated into the conceptual model along with the key components and processes. Five ecosystem respone units (ERU) were identified in the natural system, and two additional ERU 's would be imposed by oil shale development. Most of the data for driving variables and state variables were plotted against a 2.5 year time scale. Three matrices were derived from the operator 's development plan and its modification. They were the development matrix, the activity matrix, and the perturbation matrix. The model describes major interrelationships on the tract from a systems perspective, from a mainly qualitative approach.

Boats traveling at slow speeds near nests usually drove males from their nests, increasing the likelihood of egg predation. Boats moving at higher speeds or further from nests caused little or no displacement of males, but increased turbidity and possible success of predators. Location of a nest near cover increased the male's ability to protect his nest during repeated surface disturbances.

It does not show seasonal variation, possible changes in feeding habits with different growth states, or relative quantities. However simple it is, the matrix does show the relative importance of certain species to other species. An important objective of this paper is to identify gaps in knowledge in hope that such information might lead to further research in time for the results to assist developers, regulatory agencies, and local residents in making wise decisions relating to future resource development activity in the coastal zone of the arctic Alaska. It is apparent from the matrix where much information for many groups is lacking. (Sinha-OEIS) JF - Marine Technology Society Journal Vol 14, No 1, p 25-27, February-March 1980. 1 Fig, 3 Ref.

Stochastic hydrology addresses the inability to predict future inflows by examining the probabilistic aspects of the future as derived from the statistical properties of the historical sample. The basic procedure can be summarized as follows: (1) studies are made to determine the underlying statistical properties of the historical inflow. Based on this analysis, a mathematical model is constructed which preserves the historical statistical properties and generates synthetic inflows of any specified duration. By generating many sets or traces of inflow, the reservoir can be operated through a variety of possible inflow patterns, each of which gives a different estimate of project yield and accomplishments. Comparing these yields and accomplishments with the frequency of their occurrence enables one to estimate the risk or probability associated with a specified level of output. In the Berryessa analysis, 100 traces of monthly inflow, each having a duration of 70 years, were generated. In the case of enlarged Shasta, a larger sample containing 1,000 traces of annual inflow was generated, each trace having a duration of 50 years. For the benefit of those familiar with the mathematics of stochastic processes, a lag-one Markov model was used for both cases. Of the two cases, Berryessa, a single-purpose (water supply) reservoir operationally and financially independent of the CVP, is far simpler to analyze. Overall however, stochastic analysis provided useful probabilistic and operational information, although it did not remove hydrologic and related economic uncertainty. In planning a project, assumptions regarding future inflow influence the assumed project benefits. However, inability to forecast the occurrence and magnitude of future droughts dictates a conservative posture with regard to assumed project capabilities and benefits.

This paper examines the equity versus efficiency issues in rationing an ecologically based capacity whose optimum is determined by the intersection of a marginal ecological damage function from impacts of visitor use and the demand for use curve. The model was developed for the study by first estimating the demand to float Westwater Canyon, derived from a modified travel cost model. Recreational benefits of $6 ,500 under a hypothetical capacity of 50 trips, when pricing was used to allocate the permits, and a range of benefits from as low as $880 to an expected value of 3,690 if a lottery system is used, were estimated using this model. The monetization of the efficiency losses associated with more equitable allocation systems allows managers to be more objective in making the equity-efficiency trade-offs involved in picking a recreation use allocation system.

AN - 15534708; 375700 AB - There still is need for research on gas supersaturation as it relates to gas bubble disease. Better methods are required for both measurement and treatment of gas-supersaturated water. More must be understood about physiological and ecosystem responses to high gas pressures if existing tolerance data for individual species are to be applied accurately to field or fish-cultural situations. A better training program is needed for scientists, engineers, and facility operators involved in the monitoring and mitigation of gas-supersaturated waters.

AN - 15507361; 336102 AB - Gas bubble disease is a noninfectious, physically induced process caused by uncompensated hyperbaric pressure of total dissolved gases. When pressure compensation is inadequate, dissolved gases may form emboli (in blood) and emphysema (in tissues). The resulting abnormal physical presence of gases can block blood vessels (hemostasis) or tear tissues, and may result in death. Population mortality is generally skewed, in that the median time to death occurs well before the average time to death. Judged from mortality curves, three stages occur in gas bubble disease: (1) a period of gas pressure equilibrium, nonlethal cavitation, and increasing morbidity; (2) a period of rapid and heavy mortality; and (3) a period of protracted survival, despite lesions, and dysfunction that eventually terminates in total mortality. Safe limits for gas supersaturation depend on species tolerance and on factors that differ among hatcheries and rivers, between continuous and intermittent exposures, and across ranges of temperature and salinity.

Several geomorphological settings were chosen to be representative of much of the surface of the Mojave Desert, for example, playas, alluvial fans, and aeolian features. Variables which increase threshold velocity are decreasing proportion of sand, increasing size of dry aggregates of the soil, and increasing fraction of the soil mass larger than 1 mm. Threshold velocity increases with different types of soil surfaces in the following order: distrubed soils (except disturbed heavy clay soils), sand dunes, alluvial and aeolian sand deposits, disturbed playa soils, skirts of playas, playa centers, and desert pavements (alluvial deposits).

Degassing of ash erupted during 1976 by Augustine Volcano in Alaska released 525 x 10 super(6) kilograms of chlorine ( plus or minus 40 percent), of which 82 x 10 super(6) to 175 x 10 super(6) kilograms may have been ejected into the stratosphere as hydrogen chloride. This stratospheric contribution is equivalent to 17 to 36 percent of the 1975 world industrial production of chlorine in fluorocarbons.

The results show that PCP persistence is associated with absence of illumination and hydrosoil; pH value near or below 4.8, and low oxygen concentration, and the phenolic form is probably more persistent than the phenate salt.

The Suisun Marsh, located in the San Francisco Bay Estuary, is a wintering area or home for 200 species of birds, 45 species of mammals, and 36 species of reptiles. Birds wintering in the Marsh include the pintail duck, the American wigeon, mallards, shovelers, and green-winged teals. The Marsh is brackish with salinity levels ranging from 50 micromhos to 27,600 micromhos with 4,700 to 18,000 micromhos suggested as optimum for promoting waterfowl food plants. Low salinity levels occur during winter and spring when Delta outflow is high with high salinity levels occurring in summer and fall when outflow is low. Salinity/outflow equations were developed and verified to predict mean monthly salinity. The equations were used to join Delta outflow to the Marsh salinity model. Results from the use of the model indicate that in February through May Delta outflow will not be sufficient to provide optimum salinity. Various management alternatives to maintain optimum salinity levels include tide gates, waste water reuse, freshwater release, and rerouting of sloughs. Although salinity levels may be improved in the future to produce more food for ducks, duck populations may not increase. Extensive data plots are included.

During 1976-78 a U.S. interagency team, the U.S. Irrigation Water Quality Team, examined the status of irrigation water quality in the U.S.S.R. During visits to both countries and in formal exchanges of technical data, the general interest information that is presented was developed. The Soviet government is presently engaged in a large-scale land reclamation program that is bringing in new lands under irrigation at the rate of about 1 million hectares per year. Land reclamation measures include: land preparation, leaching, improved irrigation and water application systems, and drainage networks. Increased use is being made of saline lands and saline water to extend limited water supplies. Discussions are presented providing Soviet viewpoints regarding successful use of saline water in various irrigation application and an analysis of related short-term and long-term consequences and impacts. A major problem, the difficulty in regulating the salt conditions in irrigated soil, is emphasized since the problem of avoiding soil salinization using fresh water has not even been solved.

The highest reductions were achieved in the residential sector, however, consumers are slowly returning to pre-drought consumption behavior. Residential water consumption is returning to normal more slowly than consumption in commercial, industrial, and agricultural activities. Even at the height of the drought, the agricultural sector reacted mainly to economic pressures for water conservation. Four conclusions drawn from these facts are: (1) the inevitability of droughts should be recognized and should be an integral part of planning; (2) the manipulation of nature conditions is limited by ecological impacts, and by economic, social, and political factors; (3) many systems are operating at their carrying capacity and have no resilience; and (4) there is too little concern about future droughts once a crisis period has passed. The Bureau of Reclamation has identified a priority list of actual and future water problems for the 11 Western States. Problems on the list include water for energy resources development, water for Indians, Colorado River water supply and salinity, water conservation and reuse, protection of estuaries, and preservation versus development.

This theory states that the rate of energy dissipation is a minimum under steady equilibrium or gradually varied flow conditions. The theory was derived from the Navier-Stoke 's equations of motion for gradually varied, open channel flow without sediment transport. It applies to turbulent and laminar flows as long as the inertia forces due to the time-averaged velocity distribution are small compared with the forces due to gravity and shear. The theory in different degrees of generality can be used to explain the fluvial processes from the movement of sediment to the change of velocity, slope, roughness, channel geometry, pattern, and profile of a river under an equilibrium condition or during the process of self-adjustment to reach an equilibrium condition.

Analyses were made to determine the availability of water for recharge; anticipated infiltration rates; potential storage capacity of the groundwater reservoir; the degree of groundwater mounding beneath potential recharge sites; the magnitude of annual drain-out loss to the river; possible water quality problems; and the potential effects on the South Platte River flows. Artificially recharging the alluvial aquifer appears technically feasible. Water-logging conditions are likely to develop in areas that lie within 1 mile or 2 miles of the river. Due to the high dissolved solids concentration of the recharge water, the quality of the groundwater in some areas may deteriorate and preclude its use for domestic and municipal water supplies.

Block diagram and analog computer models were developed from mathematical equations modelling shaft torsional phenomena. Data calculated from several Bureau of Reclamation hydrogenerators are included. A single shaft torsional oscillation mode generally characterizes hydrogenerators. This oscillation mode is adequately damped due to viscous waterwheel damping. Results of tests at the Grand Coulee Powerplant show that hydrogenerator excitation systems have negligible effect on shaft torsional oscillations due to the large inertia of hydrogenerator rotors. An instrumentation system was developed for prototype field measurements. The system uses shaft-mounted strain gages to provide a torsional signal. The system was used to obtain shaft torsional oscillations data from three units and these data are presented along with the design and circuit configuration of the system. The information given is specifically applicable to hydrogenerators but is equally applicable to other types of generators.

The control mechanism, an analog computer controlled electronic filter level offset (EL-FLO) plus RESET was mathematically modeled, designed, constructed, and tested. The control system can handle complex irrigation water delivery schedules while maintaining nearly constant water levels in a canal system. An electronic time delay replaces the cumbersome hydraulic filter to eliminate the inherent sustained water level oscillations for automatic flow regulation systems. The RESET controller eliminates the residual water offset associated with proportional control. Laboratory simulation tests were performed to confirm that the control system was designed and built as modeled and to test equipment performance at high temperatures and high humidity. Field tests of the control system conducted at the South Gila Canal in Arizona and the Corning Canal in California verified the accuracy of the systems ' response characteristics. Following the positive testing results EL-FLO plus RESET specifications were written and 21 units were permanently installed in California on the Coring and Coalinga Canals. Extensive test result data are included.

Some changes have already begun to show on the riverbed and on both banks. Rapidly varying flow will be sustained to a magnitude approaching 400,000 cu ft/second due to peaking operations. Existing and future conditions were used as a basis for the analysis of channel stability, with consideration given to the magnitude of planned peaking flows. Recent channel surveys, bed and bank material size distributions, surface and underwater photographs of the riverbed and banks, measured velocity distributions, and observed water surface profiles were among the basic data. Nine specific recommendations for protective measures in the channel are made.

The Gunnison River, a principal tributary of the Colorado River, has an average elevation of 2,300 m above sea level for the area studied. Located along the study area are two reservoirs, the Taylor Park Reservoir which is upriver from the Blue Mesa Reservoir at the lower end of the area. Winter conditions are severe with 3 days in January of 1971 having a maximum temperature of -18 C or below with the lowest temperature being -38 C. Various river channelization, river snagging, and clearing operations have been performed in an attempt to reduce the ice jamming problem. Since 1967 with the filling of the Blue Mesa Reservoir descriptive records have been kept on the winter ice jams. Summaries of these annual descriptions are included. Study results show that the elevation of the Blue Mesa Reservoir at the end of November is a major factor in determining the location of the ice jam head at the start of the season. The higher the reservoir, the further upstream the ice jam starts. Clearing and snagging operations have had little effect on reducing the jamming, however, the construction of larger ice collection areas has helped. A good correlation was observed between upstream ice jam movement and average temperature below minus 10 C. Large releases from the Taylor Park Reservoir during the winter contribute to the ice formation problem. Data summaries, maps, and photographs are included.

All four tests are used to measure the potential dispesibility or erodibility of clayey soils which are difficult to distinguish from nonerodible clays by conventional index tests. For the pinhole test five equal lifts of sample soil totaling 38 mm in height are molded and allowed to stabilize for 16 hours in a sealed cylinder. A truncated brass cone is pushed into the upstream end of the sample and a 1 mm-diameter hypodermic needle is pushed through the entire sample to produce the ' pinhole'. After adding screens and glass spheres, the sample is placed horizontally and distilled water under a 50 mm hydrostatic head is passed through the sample. Results from this flow are used along with electrical conductivity, turbidity, and pH to measure the dispersibility of the sample. Chemical testing procedures are used to identify potentially dispersive clays by isolating and identifying soluble water cations and cations adhering to clay particle surfaces. The crumb test or aggregate coherence test involves the timed hydrating or crumbling of a 15 mm cube of soil in 250 ml of distilled water. For the double hydrometer test two identical 200 g samples are used. One sample is subjected to standard graduation analysis while the other is dried, rehydrated, deaired and then measured.

All of this can be accomplished simply without extensive expense, outage of time or sacrifice of ruggedness or high reliability. The conversion upgrades governor systems from temporary-droop type to a high order double-derivative type by replacing the dashpot function with derivative terms from an independent frequency sensor. A velocity feedback system around the valves and servomotor simplify the gate response function and aid in gate timing adjustment. Installation is simple and control can be transferred instantly since all original mechanical apparatus is retained for startup and standby. The apparatus is schematically described in detail with information on tests and alinement of electrical governors and mechanical governors by simulated isolation and trouble shooting aids.

The primary objective of this program is to provide the necessary information to permit design, construction, operation and maintenance of economical and efficient desalting systems using geothermal fluids. Three types of desalting units were tested: (1) a multistage flash (MSF) unit; a vertical tube evaporator (VTE) unit; and a high temperature electrodialysis (HTED) unit. Studies on corrosion, scale prevention, water quality, materials , and heat transfer were run concurrently with each test. All three desalting systems proved capable of desalting geothermal fluid. Problems associated with each are discussed along with possible solutions. Determination of the economic feasibility of geothermal desalting depends on other important factors such as productivity of the geothermal reservoir, compatibility of fluids, environmental concerns, and the source of replacement fluids. Data on these items are forthcoming and will provide the basis for the design and cost estimates for a production-size desalting plant. This study will include the feasibility of producing power concurrently with desalting.

In particular, how will farmers respond to a new additional water source of differing cost, availability, and quality. Linear programming computer models of representative irrigated farms in Pinal County, Arizona have been developed to project agricultural adjustments to new water from the Central Arizona Project now under construction. The models of farm enterprises in Pinal County maximize profits by maximizing net returns above variable production costs. Alternative courses of action available to the farmer include the different ways to produce a crop, the production of different levels of output for each crop , and the alternative crops which could be produced. The models reflect one crop season. The techniques developed have broad application to similar water resource projects involving the conjunctive use of multiple water sources of differing price and quality. Various management schemes can be evaluated by properly selected representative farm models.

Recently, energy companies have attempted to obtain water rights in the Yellowstone basin for energy companies have attempted to obtain water rights in the Yellowstone basin for energy conversion facilities in coal-rich southeastern Montana. Existing users fear that energy diversions will impair their rights, preclude expansion of present beneficial users, degrade water quality, and adversely affect fish and aquatic life. In response to these concerns, the Montana Legislature enacted several laws to regulate water appropriations in the Yellowstone River basin, including means by which state and federal agencies could apply for reservations of water for future beneficial uses. Thereafter, both the Montana Fish and Game Commission and the State Water Quality Bureau formally requested relatively large instream flows to protect fish and wildlife and to maintain water quality. This paper describes Montana 's experience through December 1977 with the administration of water in the Yellowstone basin under these laws; emphasis is placed on the major requests for instream flows.

Field and laboratory studies of low river discharge into the San Francisco Bay-Delta Estuary and related factors were conducted to determine the cause(s) for the low p hytoplankton occurrence. Nine factors were evaluated as possible causes: (1) available light as factors of solar radiation and water transparency, (2) water temperatures, (3) nutrients, (4) toxicity, (5) parasitism, (6) high salinity, (7) zooplankton grazing, (8) benthic filter feeding, and (9) entrapment zone location relative to shallow bays. In general, measurements of these factors during the dry years were compared to values from previous years. All factors except benthic filter feeding and entrapment zone location were eliminated as probable causes. Although the low Delta outflow conditions of the drought caused a benthic organism influx, indirect evidence indicates that the influx did not cause the low phytoplankton standing crop. Evidence does indicate that the movement of the entrapment zone from the channel and shallow production waters of the Suisun Bay into the Sacramento and San Joaquin River system was probably the cause for the phytoplankton decrease.

Oil production is now being considered for some nearshore sections of the Beaufort Sea coast. During winter in the Beaufort Sea, heavy metals in the sediments will not be dispersed; the under-ice currents are slow, and some of the bottom is covered by very saline, relatively stagnant water. Heavy metals in the sediments can probably be assimilated by epibenthic animals in the nearshore region, and then transferred through the food chain to natives who partially subsist on marine animals.

A large number of experiments and field measurements have been conducted, but none has led to a simple correlation that relates the mean air concentration with the flow quantities. The purpose of this technical note was to develop a correlation between the mean air concentration and the most significant flow parameters in the fully aerated zone. Dimensional analysis was used to evaluate the relative importance of the various parameters. An expression was developed to approximate the value of the mean air concentration in fully aerated flow. The expression correlated both field and laboratory observations relatively well. Although the expression was developed for fully aerated flow, it possibly could be used to estimate air concentrations in developing flow.

Required control and data acquisition functions will be performed through minicomputer remotes. There are three requirements for the basic control function which is the flow control system: the algorithm monitors valve flow only, the valve motors will be fixed-speed motors, and the algorithm must be a general one, adaptable to different valve characteristics and travel times. Two algorithms were developed; they are discussed and contrasted. The simpler proportion control algorithm (proportional-integral-derivative, or PID) takes up less memory to implement, but does not easily accommodate the nonlinearities of the valve. The predictor/corrector algorithm can account for some nonlinearities; also, it cuts down on the pulsing of the motor, which the PID relies on to obtain slower motor speeds. The PID algorithm would work well in flow control situations where constant head changes are taking place and relatively few set-point changes occur. The predictor/corrector is desirable in situations where there are few head changes; the added accuracy, efficiency, and adaptability afforded by it are worth the additional complexity of the algorithm.

The objective was to relate water retention of these sandy soil textural classes to particle size percentage. Water retention percentages, on an oven-dry basis, were determined for samples at field capacity under field conditions and also at 1/10-, 1/15-, and 1/20-bar soil water suction for air-dried, less than 2-mm samples in conventional porous ceramic plate-pressure pot equipment. No single soil water suction produced water retention values adequately representing field capacity for all textures. In most instances, the percentage of very fine sand alone and in combinations with the percentages of silt and clay were correlated significantly with soil water values.

A 60-acre desalting test facility has been constructed four miles west of Yuma, Arizona, with the intent of reclaiming drainage water from the Wellton-Mohawk irrigation district. Three major objectives of the project have been identified: (1) providing data on desalting models and equipment operated on pretreated water from the main conveyance channel, (2) allowing desalting manufacturers to gain experience with their equipment, and (3) providing criteria for the evaluation of desalting equipment proposed for the Yuma desalting plant. Eight reverse osmosis units and four electrodialysis units have been installed and operated in this facility to achieve these objectives. Between November 1974 and May 1978, these desalting units accumulated over 200,000 hours of operating time, and have been successful in accomplishing most of the objectives of the Colorado River Basin Salinity Control Project and provided invaluable design data relating to specific site problems.

The volume of water withdrawn greatly exceeds the volume of natural recharge, and water levels have been declining since 1923. As a result of the water-level declines, the land surface has subsided, the alluvial deposits have been subjected to stress, and earth fissures have developed. Land subsidence and earth fissures have damaged public and private properties. Subsidence and fissures will continue to occur as long as ground water is being mined and water levels continue to decline. As urban development expands, land subsidence and earth fissures will have an increasing socioeconomic impact. Information on maps includes change in water levels, measurements of land subsidence, and location of earth fissures. A section showing land subsidence between Casa Grande and the Picacho Peak Interchange also is included. Scale 1:250,000.

Earthflows are active during the winter wet season, and their movement averages 2.4 to 4.0 m/yr. Fluvial sediment yield from the gullied and broken earthflow surface is about equal to sediment yield by mass movement. Indirect evidence suggests that changes in vegetation cover due to grazing beginning in the nineteenth century may have increased the rate of earthflow movement.

The properties of continuous shears and the effective modulus of rock masses are discussed. The Joint-shear index and the Shear catalog, two new techniques developed by the Bureau of Reclamation for determining the effective modulus, were used with conventional two-dimensional finite element programs to model the foundation characteristics and behavior under anticipated dam and reservoir loads. The foundation treatment was determined based on these deformation studies. The general procedure and the explorations and studies performed to determine modes for stability analysis are described; four stability modes are discussed. The methods of analysis to be used are presented, and the critical properties of strength and continuity are determined.

Simazine was applied to both watered and dewatered sites at rates of 2.25 kg/ha (2 lb/acre) and 4.5 kg/ha (4 lb/acre). Immediately after the application, simazine levels detected in flowing canal water did not exceed 60 micrograms/L. The following spring first flow samples collected from the dry application sites peaked at 250 micrograms/L within the treated section, but dropped to less than 5 micrograms/L. In a correlated study six crops were irrigated with water containing 0.01 and 0.1 micrograms of simazine and harvested seven and 30 days after treatment. Trace amounts of herbicide were found in sugar beets, corn foliage, and tomatoes. Larger amounts were found in sugar beet foliage, and alfalfa contained the largest amounts of residue of the crops tested. No simazzine residue was found in corn grain, pinto bean pods and foliage, and cucumbers. According to a literature review, crop and canal water residue levels resulting from the experimental applicaton of simazine to inside slopes of canal banks were within established tolerance for potable water, and would produce no significant impact on crops and nontarget aquatic organisms.

The technical feasibility and social acceptability of precipitation enhancement as an alternative water resource management tool are discussed; Results of the 1976-77 winter study season and the 1977-78 season activities are discussed; future activity is previewed. In early 1976 a liquid-tank model using stratified liquid was designed to simulate wind patterns across the eastern side of the Sacramento Valley, over the Sierra Nevada, and on into Western Nevada. The model was used to study the manner in which seeding material moves under three different atmospheric conditions: a prestorm situation with a deep inversion in the atmosphere, during a storm situation, and a post-storm situation. Other activities of the 1976-77 season include: tracer and diffusion and cloud microphysical studies in the American River Basin, development of radar climatology for the Sierra Nevada, acoustic sounder observations, ground microphysics, a precipitation profile for the area from Sacramento to Truckee, California, and satellite observations and data collection. The project field office was established at Auburn.

Current theory on sediment transport in estuaries, results of other studies, and data collected in the present study suggest two-layered flow circulation patterns in the freshwater-saltwater mixing zone combined with the flocculation, aggregation, and settling of suspended particles cause suspended materials to accumulate at concentrations exceeding those found either upstream or downstream. The general area where this accumulation occurs has been termed the entrapment zone. This study demonstrated the entrapment zone location fluctuates tidally 2-6 miles (3-10 km) and moves landward with decreasing river discharge. The location of the entrapment zone is related to and can be approximated from salinity concentration, as measured by specific conductance. Total suspended solids (TSS), particulate nutrients, phytoplankton, Neomysis mercedis (Holmes), certain other zooplankton, and juvenile striped bass (young-of-the-year) are concentrated in the zone.

Described were the effects of baffle block heights and spacing of the hydraulic efficiency of the system. Impact pressures were measured on the upstream faces of the blocks to determine impact forces. Pressures on the side, top, and back of the blocks also were measured to determine the possibility of cavitation damage. Special consideration was given to develop alternative entrances to the baffled spillway. Three entrance configurations were proposed, two of which will not increase the upstream water level. The third entrance is similar to the conventional type used in contemporary designs. Typical design procedures were outlined. Included were the detemination of ideal design discharge criteria which might be less than the expected maximum and suggestions on how to modify the structure to handle discharges greater than the design. These studies indicated that this type of structure was satisfactory for any discharge, but structural and size-of-block limitations might control the quantity of the design unit discharge. Model tests of specific projects showed that the concept could be used in lieu of spillway energy dissipators at larger unit discharges. As with all new concepts, a design based on this example should be confirmed by hydraulic model studies.

The first program routes a flood past a dam using the storage equation and considers the effects of an inflow hydrograph and the operation of powerplants, spillways and outlet works. This program can calculate a progressive erosion (breach) if an earth dam is overtopped, and can simulate a piping failure condition. This program was used to simulate the events at the Teton Dam site and to calculate the outflow hydrograph during the failure. The second program, TAHS (Transient Analysis of any Hydraulic System), is a general purpose program used to solve the unsteady-flow equations in open channels, closed conduits, or combinations of both. This program was used to route the outflow hydrograph from Teton Dam to American Falls Reservoir. The results of this study were compared with the high water inundated area recorded by USGS.

Recognizing the limitations, failure hydrographs were routed through the valley downstream by means of an implicit-finite difference methods. The procedure consists of a mass balance of inflow, outflow, and change in storage per unit of time within a reach. The average hydraulic properties for all subreaches were computed from the best data available and used in the routing. Possible backwater effects caused by valley constrictions were checked by steady-flow backwater computations in which the attenuated peak flows from the flood routing were applied at appropriate valley sections. Flood elevations were adjusted upward if indicated. The results indicated that an application of the mass continuity principle alone, as in a hydrologic routing, is quite inadequate for modeling the rapidly changing flow characteristics just downstream from a dam break. The routing improves in reliability as the speed of the flood wave decreases.

Additional drawings and appendices are included in Volumes 2 and 3. The investigations were conducted in the immediate area of the damsite by the USBR Auburn project Geology staff with input from independent consultants. They are concerned principally with the structural and stratigraphic relationships of features in the site area and influence determination of the potential for surface faulting in the dam foundation. It was concluded that a Mesozoic, regional fault system is present both upstream and downstream of the damsite. A shear zone located within 1/2-mi. from the site is inactive by USBR criteria. A fault zone known as F-1, believed to be part of a local fault system, has moved last, relative to other major structures, in the damsite and the possibility of movement along structures termed T-zones is not credible.

As these areas continue to grow, additional water supplies must be developed to meet their needs. Diversion structures and low head dams will be built as part of these expanded water supplies. Typically, these structures are comparatively low and their spillways will operate at low Froude numbers. Palmetto Bend Dam stilling basin is an example of a low Froude number structure modeled recently in the Bureau of Reclamation Hydraulic Laboratory, and the recommended design is quite different from available low Froude number designs. As a result, hydraulic model investigations were performed to develop a design that would be suitable for a low Froude number stilling basin. The design developed during these studies usually will be adequate without model tests, unless approach or outlet flow is asymmetrical or unless testing is needed to develop a smaller stilling basin. Some of the criteria developed from this model study were location, size and type of baffle piers, chute blocks, end sills, length of the basin, and tailwater depth. The above criteria and guidelines from previous studies were combined to formulate the design guidelines recommended for the low Froude number hydraulic jump stilling basin.

Windpower is considered in association with pumped-storage hydroelectric plants for load leveling and existing types of transmission lines for interconnecting the wind farms and energy-storage sites with load centers up to 2000 km away. Potential energy harvest from wind farm sites in the 17 Western States is estimated at well over 100 GW, and many times this much in arctic North America. At the 100-GW level of development, bus bar cost at the wind farm would be about 3 mills/MJ (10 mills/kWh). Energy storage required for load leveling would add about 1.8 mills/MJ and transmission costs another 2.1 mills/MJ, for a total cost at the load center of 6 mills/MJ (21 mills/kWh), all in 1976 dollars. This would be competitive with energy generated near load centers by new nuclear or fossil-fuel powerplants. Windpower appears environmentally acceptable and avoids many of the environmental liabilities of conventional sources. Large-scale windpower implementation will require major advance commitment of capital, about $1 billion, to lower bus bar costs to 4.4 mills/MJ (16 mills/kWh). The timetable will therefore likely depend on Federal incentives. (Bur Reclam) JF - Bur Reclam Engineering and Research Center, Denver, Colorado August 1977. 29 p, 11 fig, 1 tab, 32 ref.

Variables are being developed and investigated to establish generalized seedability criteria that are applicable under a variety of meteorological and topographic conditions. The variables are divided into four general categoreis: time available, water available, nuclei available, and mixing available. The analysis approach is to establish ' windows ' under which positive (increases) or negative (decreases) seeding effects would be obtained. Thus far , the analysis shows that positive seeding effects occur at the crest under stable or unstable conditions when a ' crest trajectory ' is present, moderate-to-high cloud moisture is present, and the cloud top temperature is between minus 10 and minus 30C. Decreases occur at the crest for unstable clouds with a ' blow-over ' trajectory, with low cloud moisture and cloud top temperature colder than minus 30C. The precipitation for upwind and downwind regions of a barrier can also be increased or decreased depending on stability, trajectory, cloud moisture, and cloud top temperature. Other windows are discussed. (See also W78-02407) JF - Skywater Monograph No. 1 July 1977. 119 p, 30 fig, 8 tab, 6 ref, 2 append.

These are the transient-response method and the frequency-response method. Since a typical canal system is influenced predominantly by transient inputs, the transient-response method has been extensively used in the analysis of automated canal systems. The main advantage of the frequency-response method is that the effects of varying the various control parameters can be readily visualized and evaluated. The presently used transient-response method and parameter selection are reviewed. The basic concepts of the frequency-response method are presented and their application to an automated reach is illustrated with an example. Two computer programs are given which can be used to determine canal response characteristics. The state-of-the-art in process control has progressed sufficiently so that both the transient-response and frequency-response methods of analysis can be used in a complementary fashion. Employment of only one method in the design of automated systems is, in general, wasteful of both computer time and engineering effort.

The discussion focuses on western states of the Federal Energy Administration 'S Region VIII. In the upper and lower Colorado River basin water will probably limit energy development, but not in the upper Missouri River basin. Average annual water supply in the upper Colorado basin is about 5.8 million acre-feet, of which 3.7 million is actually consumed, leaving only 2.1 million for additional development. Estimated water demand for the year 2000 is over 2.5 million acre-feet of additional water, for energy, municipal and industrial use, agriculture, fish and wildlife, and recreation. The upper Missouri basin has an annual flow of 28 million acre-feet, of which only six million is used. The era of major federally funded water development in the United States is ending; federal water planning will now focus on national economic development, environmental quality and water conservation. Regional development has ceased to be sanctioned as a national water resources policy objective. At the National Water Conference Secretary of the Interior Andrus indicated that nonstructural water planning and management measures will have equal status with structural ones, non-federal entities will be required to bear a larger share of project costs, and water allocation practices will be reviewed and revised.

Both appendices are reports by Roy J. Shlemon, a private consultant hired by the Bureau of Reclamation, to perform geomorphic investigations to augment those of Woodward-Clyde Consultants. Appendix 5 - Soil-Geomorphic Investigations - Auburn Dam, California - Preliminary Phase, is a report of field reconnaissance to determine the possible presence and time of last movement of faults located at or near the proposed damsite. Estimated ages of paleosols, the characteristics and distribution of clay-filled fractures in the Mehrten formation, and colluviation of the Mehrten formation are presented, both generally and specifically as they related to shearing in the dam vicinity. Appendix 6 - Soil- Geomorphic Investigations, Maidu East Shear and F-O Fault Zones, Auburn Dam area, California, addresses the dating of two shear zones in the damsite area. Shelmon concludes that the Maidu East Shear Zone is inactive and the age of last movement on fault zone F-O is indeterminate. (See Also W78-09018) (Bur Reclam) JF - June 1977 84 p.

Samples were collected at high slack tides three ft below surface with submersible pumps or Van Dorn samplers. Dominant phytoplankters throughout the delta and into San Pablo Bay were diatoms; green algae seldon exceeded 20% of the total. Planktonic chlorophyll-a concentrations in the Sacramento River, the major water source to the delta, were generally under six micrograms/l. During spring, summer, and fall the shallow San Joaquin River contained a very high percentage of wastewater; peak summer chlorophyll concentrations were 100-250 micrograms/l, inversely related to riverflow. Most of this highly productive water was drawn to the export pumps during the summer. In the eastern delts sloughs and channels, chlorophyll levels were often quite high and varied erratically. Spring blooms of 30-40 micrograms/l and summer blooms of 40-100 micrograms/l were observed in the Suisun Bay area. Chlorophyll-a concentrations in Suisan Marsh generally peaked in late spring at the 40-100 micrograms/l range. In the channel through San Pablo Bay chlorophyll levels seldom exceeded six micrograms/l. Of total chlorophyll-a plus pheo-pigments, chlorophyll-a near the water surface amounted to 50-80% during spring-fall throughout the study area.

The desalting plant will be constructed to treat the drainage waters from the Wellton-Mohawk Division of the Gila Project so these waters will be available for delivery to Mexico under the 1944 Mexican Water Treaty and Minute No. 242. By reducing the volume of drainage flows, the size of the desalting plant can be reduced. An interagency committee was established to determine and implement means of increasing irrigation efficiencies so as to reduce drainage return flows to the lowest practical volume and to identify an optimal economic solution relating desalting costs to specified irrigation efficiency levels. An assessment was made utilizing the water budget process to determine the relationship between increased irrigation efficiency levels and drainage return flows.

The problems of water quality have been especially acute for Mexico, which has received water of increasing salinity in diverting procedures allowed by a 1944 treaty with the United States. The reasons for increased salt concentration are explained, along with remedies provided in treaty agreements since 1965. Title I of the Colorado River Basin Salinity Control Act authorized a desalting complex to reduce salinity of the Wellton-Mohawk drainage, a new concrete-lined canal or lining of the existing canal to replace the first 49 miles of the Coachella Canal, and a protective and regulatory groundwater pumping program for the South Yuma Mesa and southwestern Yuma Valley. The proposed desalting plant will be the largest in the world, with membrane type desalting units (either a reverse osmosis or electrodialysis process) used. Plant design and uses are discussed, along with preliminary tests to determine ways of increasing irrigation efficiency. The groundwater pumping program will produce a yearly net water savings of about 125,000 acre-feet, while the desalting complex will salvage 123,000 acre-feet.

This radiation is produced by the radioactive decay of Radon and Thoron gases, which in turn result from Uranium and Thorium decay. These latter elements are found in all terrestrial rocks and soils in varying, though minute, concentrations. The decay products of the two noble gases which cause a potential health hazard are the short lived ' daughters. ' These are solids. This decay yields the alpha radiation which as a large ionizng effect on lung tissues. Continuous exposure of many years (5 or more) may cause lung cancer. Lung cancer has been documented to be anomalously high among uranium miners. Smoking has a contributory effect which greatly increases the radiation health hazard. Health standards are set by several government agencies: Environmental Protection Agency, Occupational Safety and Health Administration, Mining Enforcement and Safety Administration (MESA), and National Institute for Occupational Safety and Health. The NPS research has the dual but complementary objectives: (1) To safeguard health at the NPS administered caves, and (2) To develop data on alpha radiation levels and on natural airflows in caves. The results can be used by various agencies to clarify health standards for exposures to lower radiation levels in cave environments. All persons who spend considerable time underground in caves may be exposed to alpha radiation produced by the radioactive decay of radon and thoron gases. Therefore, underground areas should be monitored for this radiation, and exposures should be computed using the procedures , equipment, and standards of MESA and other agencies as described.

Pretreatment using the ion exchange (IX) method entails a continuous cycling, one process unit operation with low operating and capital costs. Water imported from LaVerkin Springs, Utah, was tested at the Bureau Testing Desalinization Test Station, Longmont, Colorado, using the IX pretreatment method. The calcium in the raw LaVerkin Springs (LVS) water was reduced below sulfate fouling concentration by IX, desalting was accomplished by RO, and the recovered reject brine was used for regenerating the spent IX resin. Test results show that IX pretreatment of LVS water can be operated as a closed-loop exhaustion-regeneration cycle, and only the reject brine from RO need be used to regenerate the IX resin.

The study was initiated in 1971. Biweekly and monthly measurements were made of water temperature, dissolved oxygen, conductivity, pH, alkalinity, nutrient concentrations, phytoplankton numbers, chlorophyll a, primary productivity, zoopla ton, concentrations, and coliform bacteria. Phytoplankton and zooplankton success patterns are described. The factors affecting the deposition and distribution of enteric bacteria in Las Vegas Bay are discussed. The distribution of water and enteric bacteria of possible fecal origin into Las Vegas Bay from Las Vegas Wash were determined. The standard methods and techniques for enteric bacteria are examined. The metalimnetic oxygen minimum was caused by biological respiration of the zooplankton and phytoplankton. The high algal biomass and primary production in Las Vegas Bay are caused by the nutrients carried by the dense current on the bottom of the Bay from Las Vegas Wash. The inner portion of Las Vegas Bay is classified as eutrophic, while the outer portion and Boulder Basin are classified as mesotrophic. The most limiting nutrient appears to be nitrogen.

Volume I - Hydraulic and Safety Characteristics of Selected Grate Inlets on Continuous Grades AN - 19191062; 7900714 AB - Eleven drain inlet grates were tested to evaluate their safety characteistics for bicycle as well as pedestrian traffic. Four of the grates that rated highest in the safety tests were selected for hydraulic testing. Three other grates with designs and bar spacings similar to grates proven safe also were selected for hydraulic testing. A parallel bar grate was included in the hydraulic test program as a standard with which to compare the performance of the other tests grates. Hydraulic and debris tests were performed on full-size grates in sizes of 2 ft by 4 ft (0.61 m by 1.22 m) and 2 ft by 2 ft (0.61 m by 0.61 m). The grates were tested at cross slopes of 1:48, 1:24, 1:16 and longitudinal slopes of 0.5, 1, 2, 4, 6, 9, and 13%, with gutter flows up to 5.6 cu ft/s (0.158 cu m/s). Debris tests were run using 150 pieces of 3 inch by 4 inch paper debris. Test results showed that two of the grate designs (a cast and a steel fabricated grate) are nearly as hydraulically efficient as the parallel bar grate and considerably more efficient than the other grate designs tested. One other design (a steel fabricated grate) showed high hydraulic efficiencies at longitudinal slopes up to 6%. These three grate designs were recommended for additional testing. A grate 's ability to handle debris without clogging was shown to be most dependent on the spacing of its longitudinal bars. Grates with the widest longitudinal bar spacings tested consistently outperformed grates with narrower longitudinal bar spacings.

The Sinkhole Plain is flanked on the north by the sandstone-capped Chester Escarpment and Chester Cuesta. The occurrence and movement of groundwater in the Principal Aquifer is traced from the highest recharge area, just beyond the south and east margin of the Sinkhole Plain. Water is found in numerous small swamps of the Glasgow Upland, which feed perennial springs that feed streams that sink at this margin. Water from the swallets flows to cave streams. These low-order tributary streams join intermediate-order tributaries and, finally, a high-order trunk stream that discharges at a major spring along Green River, Barren River, or Little Barren River. The streams that flow beneath the Sinkhole Plain are fed also by runoff into sinkholes and direct infiltration. The streams that drain beneath the Chester Cuesta may be fed not only from the Sinkhole Plain, but also by runoff from ridge tops, infiltration from karst valleys, and by spring discharge from two perched aquifers. Dye-tracing over distances of as much as 24 km has begun to delineate the major groundwater basins. Systematic location of numerous caves and sinkholes in which subsurface streams are intercepted as they flow to their base level outlet, as well as mapping of selected major caves that serve as groundwater conduits, has yielded unique and valuable information about the nature of the dendritic plumbing system that drains the upper part of the Principal Aquifer. Thirteen groundwater basins have been recognized; all but 2 of them are characterized by distributary complexes 50 m to 4 km wide which discharge at 1 or several springs at each of 2 to 14 locations. Only 1 regional spring, Turnhole, lacks a distributary complex. Trunk conduits are commonly as much as 14 m wide. Water levels in them fluctuate as much as 30 m in response to storms.

Processes simulated include evapotranspiration, unsaturated and saturated water flow, solution-precipitation of slightly soluble salts, ion exchange, ion pairing, nitrogen transformations, crop uptake of nitrogen, and the movement and redistribution of salts and nutrients. The dynamic non-steady-state model predicts the concentrations of calcium, magnesium, sodium, ammonium, bicarbonate, carbonate, chloride, sulfate, N03-N, and Urea-N contained in soil, aquifer, and drain water. Concentrations of organic-N; exchangeable calcium, magnesium, sodium, and ammonium; and gypsum are predicted within the soil and aquifer materials. Users ' manuals for each basic subprogram are included, and a sample problem illustrates the use of the model. Model output can serve as input to the conjunctive use model. Model output can serve as input to the conjunctive use model described in Volume III; serve as input to other models on a nodal or point source basis; or stand alone depending on the type and scope of the particular study.

The objective of this report is to describe the surface circulation during open water. The investigation was conducted primarily in the region between Icy Cape and Point Barrow and seaward to the pack ice edge. A chart of this study area is shown. Analysis of the surface currents inside the 18m depth contour taken in August 1976, in the Chuckchi Sea show a southerly flow under the influence of the prevailing easterly-northeasterly winds and that this flow is reversed with little observable time lag when the wind is from the southwest or west. The statistical correlation between wind and water movement gives a means for predicting the rate of movement of pollutants released into this arctic coastal environment. The importance of this southerly flow is that if oil moving offshore or in a spill were to occur offshore, oil could become entrained into the current and be carried south rather than north as the surface currents closer to shore might suggest.

Large as it is, the park does not include the northern and eastern reaches of the swamp, although it remains dependent upon the continued flow of water from those areas. Currently, the park 's most critical concern is over an area known as Taylor Slough, approximately ninety square miles of which lie outside of the park. The immediate economic interests of private corporations seem to favor responding to increased pressure for agricultural, industrial and residential development in the region. Section 208 of the FWPCA which establishes state responsibility for water management planning to achieve comprehensive state plans controlling future use and development of waters within the state is a key provision which has been selected for special demonstration projects. Although the proposed 208 demonstration project for the park is only beginning to take shape in raw outlines, the future of both the plan and the park looks bright.

The basic assumption is that the recreational use of a river is the most demanding of a high water quality compared to the other uses of the river. Types of decisions for which the model can be used as a basis are given; the usefulness of the model is discussed via two hypthetical situations.

Federal and state policies, agencies, and water rights are often in conflict with one another and with those claiming rights under state laws such as farmers and cattlemen. The Bureau of Reclamation has in addition entered into contracts with major energy companies for sale of water rights, sparking an interagency dispute. Indians of Montana 's Crow and Northern Cheyenne Reservations and Wyoming 's Arapahoe and Shoshone Tribes of the Wind River Reservation are directly affected by the conflicts. This paper traces the development and implications of the conflicting federal, state, and Indian claims under four headings: (1) development of federal and Western water law, (2) the clash of federal and state water rights, (3) nature and extent of Indian water rights, and (4) federal resource programs and Indian water rights. Several judicial decisions are reviewed, including the crucial Winters v. United States (1906) which enjoined the defendant against diverting water away from a Montana reservation. Underestimating water needs for coal-related industrial projects has been a major cause of the problems. (Lynch-Wisconsin) JF - Law and Contemporary Problems Vol. 40, No. 1, p 77-96, 1977. 118 ref.

Laboratory studies were conducted to determine effects of xylene on rainbow trout, Salmo gairdneri, and to measure dissipation of xylene residues in irrigation waters as treated water flowed through canals, irrigated fields, and into return flows. Rainbow trout exposed to emulsified xylene for 2 hours survived a concentration of 7.1 p/m (parts per million), but suffered 100 percent mortality at 16.1 p/m. An off-flavor was produced in fillets of rainbow trout after exposure to 7.1 p/m of xylene for 2 hours, or to 0.36 p/m for 56 days, and was dependent on concentration and exposure. Residues of xylene in fillets of rainbow trout and off-flavor was directly related. Xylene dissipated downstream in irrigation canals, from treatment concentrations of 548 to 760 p/m to an average concentration of 100 p/m or below after the water traveled 10 miles. Xylene residues dissipated in treated irrigated field waters during furrow irrigation from 150 p/m at the head ditch to less than 0.2 p/m in return flows. The xylene residues entering aquatic habitats in return flows from irrigated fields should not seriously affect fisheries or other segments of the aquatic environment.

Use of the methods and values suggested can reasonably predict the initial (no time effect) deflection of buried flexible pipe under fills up to 15 m (50 ft.). The E ' values vary according to the type of soil placed beside the pipe and the degree of compaction. The accuracy of predicted deflections varies according to the degree of compaction. Laboratory soil container tests and data from over 100 field installations were used in the investigation. (Bur Reclam) JF - Report REC-ERC-77-1 January 1977. 60 p, 12 fig, 2 tab, 13 ref, 4 append.

The services available in U.S.A. include critical reviews prepared by information analysis centres, indexing and abstracting services, coupled with the publication of abstracts journals, and U.S. Government information services organized by various government departments and agencies which store data obtained from monitoring programmes as well as publications from government and other sources. Finally the function and capabilities of the Water Resources Scientific Information Centre of the U.S. Office of Water Research and Technology are outlined. This organization identifies institutions with existing data collections and areas of competence and arranges for the abstracting and indexing of widely held documents with the aid of standard precoded forms, these representing the input to the central data bank. Based on this information a journal entitled Selected Water Resources Abstracts is published twice a month, together with certain topical bibliographies as required. A further data bank holds a catalogue of water-related research projects. The nature of the computer searching and retrieval systems are briefly outlined.

Other forms of energy from converting coal require water. Sources where substantial water supplies are available are limited, but there are some that could serve Montana, Wyoming, and North Dakota. Sources are primarily in Upper Missouri River Basin and tributaries. The Yellowstone River Compact allocates water between Montana and Wyoming on four interstate tributaries. Existing storage impoundments are preferred. Locations, capacities, and streamflow are shown. Possible routes and cost of water conveyance have been determined in studies by the Bureau of Reclamation. Energy companies hold options to some stored waters. Ground water from Madison Formation deep beneath the Fort Union-Powder Basin Coal Region is possible as an alternative water source. Federal and state cooperation is required to make developments possible, and developers are required to satisfy environmental statues.

Forecasts indicate more will be needed in the years ahead. Their tasks are constantly changing and they are being required to adapt to amplified responsibilities in connection with the search for new and varied sources of energy in which water plays a critical role. In addition, our engineers are being asked to adopt the role of educator in training and inspiring the engineers of developing nations in order that these countries may become self-sufficient in food and power production. The ways in which formal engineering education itself should modify the traditional approach and broaden the social and political consciousness of the developing engineer and aid the practicing professional are covered. The future requirements for Federal manpower are explored. The varied disciplines necessary to solve new problems in desalting, wastewater treatment, and weather modification are summarized.

Values so obtained may be substantially greater or less than those obtained by laboratory analyses of water samples from the same zones. Therefore, it is necessary to establish calibrating coefficients by borehole sampling and laboratory analyses.

Twin Lakes is a pair of Rocky Mountain glacial lakes on Lake Creek, an Arkansas River tributary, in Lake County. The lakes are classified as relatively oligotrophic, second-class dimictic lakes, although the benthic fauna is more characteristic of mesotrophic lakes. The water temperature range is 0-20C; the lakes freeze over from December to May. Benthic samples were collected from both lakes during June 1974-April 1975. The ubiquitous mysis shrimp (Mysis relicta) was found on and within the bottom environment. Few benthic macrofauna were found, but were much more abundant in the lower lake than the upper lake, even though there is little limnological difference between the lakes. The upper lake presently has the most sparse benthic fauna of any lake reported , while the lower lake is about average. Mollusks included fingernail clams (Pisidium casertanum and P. pauperculum) and Diptera included midge-fly larvae (Chironomus sp, Phaenopsectra sp, and Dicrotendipes modestus). Chironomus was the most abundant group, increasing with depth; clams were found almost exclusively in the lower lake. A severe winter usually results in anaerobic bottom conditions and dissolved heavy metals in the upper lake.

Samples were obtained during June-September 1975, prior to the opening of the Mt. Elbert Pumped-Storage Powerplant. Bottom samples from four permanent stations show that bottom muds are relatively free of coliform bacteria (less than 100 per gram), but contain high concentrations of iron bacteria (40-2400 MPN/g) and detectable amounts of sulfur bacteria. It is concluded that pipe corrosion could occur where buried pipe would be wet most of the time and anaerobic conditions exist. Large, high-velocity pipes highly aerobic water may not be affected unless stagnant areas develop near pipe walls and seams. Twin Lakes, a pair of glacial lakes in the Rocky Mountains, is a popular recreation area and thus susceptible to bacterial water pollution. Samples taken on the upper lake yielded higher total coliform counts (mean 3.1-6.4 than the lower lake; the highest counts on the upper lake (10-25) were recorded during September, probably due to higher air temperatures and increased visitor use.

This data, combined with existing quantitative data, will provide a comprehensive base of ecological information on the lakes. The lakes are being enlarged to serve as the powerplant afterbay for the Mt. Elbert Pumped-Storage Powerplant. The plants pumpback capability and generation mode have the potential to substantially modify the aquatic ecosystem. Qualitative data are in the form of plant and animal observations, underwater photography, aquatic plant identification, and descriptions of bottom characteristics. Results show that both lakes contain numerous rocks ideal for lake trout spawning areas. Mysis shrimp were observed in both lakes with a high density near the powerplant tailrace. Fish observed include lake trout, suckers, rainbow trout, and smelt. Lake bottoms were found to be rocks and gravel interspersed with vegetation in shallow areas and easily disturbed glacial flour in the deep flat bottom areas. Details of diving methods are provided to illustrate the use of SCUBA diving in ecological studies of high altitude lakes.

This is approximately 25 percent of the total project cost at current price levels. The decision of the Secretary of the Interior to allocate Central Arizona Project water to central Arizona Indian tribes is cited as the most important single decision affecting the project. It paved the way for negotiations for the sale of CAP water to municipal, industrial, agricultural and other water-user agencies. The Orme Dam and Reservoir and its possible exclusion from the project is discussed. Negative publicity towards certain aspects of the CAP is described as a powerful weapon against the project.

Computer simulation studies of the operation of the Unit were conducted to estimate the quantity, quality, and timing of irrigation return flows and determine their effects on the James River. This analysis included detailed investigations of the irrigation water and lands to be irrigated, the major elements of return flow (deep percolation, canal seepage, and operational wastes), augmentation releases of water to the James River, natural flow of the river, and operation of project features for storage and regulation of water for irrigation of the Unit. Under natural conditions, total dissolved solids (TDS) levels of James River streamflow are relatively high, averaging about 786 mg/l at Huron. Study results show that TDS levels of the river could be maintained below 1,000 mg/l (current South Dakota water quality standard for the river reach immediately below the project) during the irrigation season, but concentrations during the winter season would frequently exceed that level. Streamflow would be stabilized, however, eliminating very low and highly concentrated flows.

The model simulates one-dimensional unsaturated flow and two-dimensional saturated flow (to tile drains), as well as chemical reactions and transport processes involving the major cations and anions, and nitrogenous species. The program also includes crop uptake of water and nutrients. A numerical integration technique is utilized to solve the appropriate differential equations, and generate transient predictions throughout the soil-aquifer system, and at the drains. Utilization of a master site technique allows application of the model to predict irrigation return flow quality and quantity from large irrigated areas involving thousands of acres. Verification has been accomplished on large acreages as well as field plots, lysimeters, and laboratory columns. The model has a well-documented user 's manual and has been applied to several large irrigation projects.

This test was performed to determine the effect of different angles of pullout on the load resistance of these two footing types which were cast-in-place in a compacted silty clay. The tests were performed on instrumented, reinforced concrete model footings. The results show that the greatest load resistance is obtained with a belled footing and also is greater when the pullout force is at an angle. (Bureau of Reclamation).

A computerized mathematical temperature model, incorporating the conservation of heat equation and an equilibrium temperature approach to heat exchange, was developed for this purpose. The model was calibrated, using 1974 average daily meteorological and hydrological data, to observed temperatures at three river stations, covering a total distance below the dam of 70.0 kilometres (43.5 river miles). The average monthly error between predicted and observed mean daily river temperatures at these stations ranged from 0 to 1.2C (0 to -2.2F). The calibrated model was used to simulate river temperatures for the case of only two penstock intake structures modified for selective withdrawal and for all three intakes modified. Simulation results indicate that, while the two-intake modification strategy would result in river temperatures significantly nearer the optimum fishery range than those recorded in 1974, operation with all three intakes modified would generally result in optimum fishery temperatures from May through September. The computer model developed in this study could be adapted to a variety of data and stream conditions.

The alluvium of the North Platte is extensively developed for irrigation purposes and the effects of large-scale pumpage are of major concern. Actual withdrawals are estimated to by 46,000 acre-feet. Should pumping reach potentially higher levels an overdraft is expected. Effect of ground water withdrawals are established from projections of the flow regime within the alluvial aquifer. A time dependent, numerical model was employed to predict aquifer response to increased withdrawals. The results suggest that more efficient use of surface waters and/or increased use of ground water will reduce the annual subsurface return flow to the North Platte River and its tributaries by an amount equal to the reduced ground water increment. Alternatives are available for management of the lower North Platte alluvial aquifer. The preferred course is to correlate surface and subsurface water rights, in light of convenience, economics, and best means of storage for maximum utilization of the single water resource.

In arid western lands where water is of critical importance, non-Indian demands on a limited supply of water have already diminished the economic potential of some reservations. Very often the Department of the Interior and other federal agencies have encouraged these non-Indian demands in derogation of the fiduciary duty owed the Indian people. For example the Supreme Court has recognized Indian tribes ' retention of sufficient water rights in the Upper Missouri River Basin. Developments in that area now indicate that the government has failed to fulfill its responsibility. Agencies have entered into contracts and issued memoranda which encroach upon Indian water rights established in the landmark decision of Winters v United States. The Winters Doctrine places an affirmative duty upon the federal government to protect Indian water rights, present and future. However, an examination of six main stem dams on the Missouri River reveals a pattern of taking of Indian property for public use without payment. As the need for industrial water grows, this pattern is likely to be continued. (Molloy-Florida) JF - South Dakota Law Review Vol 21, No 2, p 282-309 (Spring 1976). 1 map, 86 ref.

In situ low-strain shear wave velocity determinations have been performed on a number of existing zoned earthfill dams and an earth dam under construction. These field measurements of shear wave velocity by geophysical exploration methods have become an integral part and standard procedure at the Bureau for obtaining input parameters for dynamic analyses of earth dams. In the course of shear wave velocity measurements, various borehole methods, such as downhole, crosshole, and uphole, as well as seismic refraction have been used. Shear wave velocity measurements have been performed with explosive and nonexplosive impulsive energy sources using cased and uncased test holes. The results of these field studies have not only provided input parameters for dynamic analyses, but have also provided information as to which method or combination of methods should be used to obtain optimum results. Test methods and results of the various in situ measurements are compared and evaluated. (Bur of Reclam) JF - Report REC-ERC-76-6 April 1976. 40 p, 30 fig, 29 ref.

Quality, specifically total dissolved solids, may be successfully generated jointly with flow. In actual application to the Colorado River Basin, results were obtained which are valuable for planning and evaluation purposes. By using stochastically generated flows and qualities, the effects of various structural or nonstructural measures in the basin may be more realistically assessed under a variety of potential future flow and salinity conditions. If the measures had been analyzed with the set of historical flows and salinities, the assessment would have been incomplete and biased. This approach is expected to be applicable to other basins with similar success.

These high dissolved gas levels, which are caused by the deep penetration of the flow into the spillway stilling basin pool, have had adverse effects on the fishery. Structural modifications were considered which included a flattening of the trajectory of the jet from the 762-mm (30-inch) bypass and the addition of a deflector or flip lip to the auxiliary outlet works. A 1:48 scale hydraulic model was used to refine and evaluate these modifications. Depth of jet penetration, degree of energy dissipation, strength of back eddies returning into the stilling basin, potential for cavitation development below the flip lip, and simplicity of design were factors considered in the evaluation.

The neutron probe design has been changed to combine the scaler with the shield and provide a useful field tool from what has traditionally been used almost exclusively for research. The technique used for scheduling irrigation requires only the identification of the refill point for each field and the neutron measured water content with time. Evidence collected from 40 fields with 7 crops during the summer of 1975 shows inconsistent irrigation timing with respect to available moisture. Consistent timing alone could improve water use efficiently by more than 10 percent. The neutron probe measurements of soil moisture depletion yield values of transient water use by plants as well as transient water loss by drainage. These two values together, divided by the water applied yield the efficiency for the field.

The 1957 degradation study, based on a detailed bottom sediment sampling program in 1956 and an analytical approach to sediment transport and armor, resulted in a prediction of about a 1.22-meter (4-foot) degradation immediately below the dam and 8.26 million cubic meters (6,700 acre-feet) of erosion to take place in the reach above the mouth of the Paria River in about 14 years. To verify changes since closure of the dam, resurveys of cross sections in the approximate 24-kilometer (15-mile) reach of the Colorado River from Glen Canyon Dam to the mouth of the Paria River near Lees Ferry were made in 1959, 1963, 1965, and 1975. Bottom sediment samples were also collected in 1966 and 1975 to analyze the changes in material size as a result of the degradation and armoring process. The resurveys confirmed the 1957 predictive study by noting that sufficient armoring material remained to control excessive degradation with about 9.87 million cubic meters (8,000 acre-feet) of material scoured from the channel bottom by 1975. This paper summarized the 1957 predictive study of probable degradation and described the changes that have taken place in the channel from 1956 to 1975.

The findings of studies conducted in 1973-74 on the sediment-clam deposition problem in the DMC were summarized and it was concluded that sediment in the water is bound by the excreta of the Asiatic clam (Corbicula manilensis). This accumulation of sediment-clam deposits causes a reduction in canal capacity, in addition to the design deficiency loss. Also, sediment transport characteristics of the DMC and the California Aqueduct were compared. Significant differences between the two intake facilities were indicated. Approximately 70% of the sediment entering the Aqueduct was deposited in Clifton Court Forebay and Bethany Reservoir, while only 10% was deposited in the DMC intake channel. The difference in sediment deposition was attributed to differences in design and operation of the intake facilities. The concentration of total suspended solids entering the DMC was found to vary directly with total delta export and vary inversely with the solids concentration of the Sacramento River, the primary source of delta export water.

However, along much of the lower Colorado River, channel and bank stabilization work is still required to reduce the sediment transport to a practical minimum within multi-purpose concepts for control and usage of the river facility. In the 238 kilometer (148 mile) meandering river channel from Parker Dam to Imperial Dam, sediment is continuing to be transported downstream in large quantities. The amount transported is largely contingent on the flow in the river and the degree of stabilization. Some reaches of the river have received stabilization treatment while other reaches have not. Since about 1963 water has been released from storage at Parker Dam only in the amount required for downstream irrigation and domestic uses and for scheduled deliveries of Treaty water to Mexico. As a result of these conditions, an annual average of about 726,000 metric tons (800,000 U.S. tons) of sediment have passed Imperial Dam in recent years. In addition, however, there has been a continued buildup of sediment in the reservoir. In the design of Imperial Dam, quite different sediment control facilities were provided for the two canal diversions. The All-American Canal desilting facilities consist of three double basins with 12 large rotating scrapers in each half basin. On the Gila Gravity Main Canal a flushing-type settling basin was used. Sediment from the control facilities is returned to the river below Imperial Dam where it is sluiced downstream to Laguna Settling Basin. At this location sediment is periodically removed by dredge. Dredging is also required periodically to keep a channel open to the Gila Canal headworks.

Storage in the 27,000,000 acre-foot reservoir began in 1963. Preconstruction studies indicated that sediment would accumulate at an average rate of 85,400 acre-feet per year over a 100 year period. In 1968, 1970, and 1973 the Bureau of Reclamation conducted limited, reconnaissance grade surveys in the delta areas of the reservoir in order to monitor the sediment build-up and its relationship to recreational uses on the lake. Deltas in the two major tributary arms of the reservoir were found to be developing approximately as expected, with their configuration, at this early stage in the reservoir 's life, strongly influenced by the original channel topography and the rising water surface. Relatively large delta build-ups have been noted in some of the smaller tributary canyons. Experience and data gained during these limited surveys will be put to use in laying out a monumented sediment range network when the time comes for the first complete volumetric survey of the reservoir. Baseline data for the volumetric survey will come from existing large scale, small contour interval topographic maps of the reservoir basin.

Tests indicated that movement of riverbed material results from operation of the river outlet works at discharges greater than 3 ,000 cu ft/s (85 cu m/s). Several solutions to the problem were suggested, including a limitation on operation of the river outlet to 3,000 cu ft/s (85 cu m/s). Studies were conducted to determine the effectiveness of the spillway discharge in clearing various amounts of deposited material from the basin. As a result of these studies, a recommended spillway discharge was applied to the Canyon Ferry stilling basin to clean 900 cu yd (688 cu m) of riverbed material from the basin. Soundings of the basin were taken immediately after the suggested release and confirmed the model results.

Public demands also receive major consideration in the decision-making process. The experience of the Bureau of Reclamation in the Mohave Valley after construction of Parker Dam was discussed. Aggradation above Lake Havasu caused a critical situation near Needles, California, where railroad facilities and other developments were inundated or threatened by the rising river. This prompted passage of Federal legislation and authorized the Bureau of Reclamation to take the needed action. In its early stages, the river management program centered on reconstruction of the river channel by dredging and related work. It evolved by stages into a comprehensive program which now includes the improvement of the river and related features for fish and wildlife, general recreation, and other uses. The gathering of sediment and hydraulic data is an essential part of the overall program. Selected information from the data collection program was summarized to illustrate some of the changes brought about. The changing requirements in the Mohave Valley were discussed. Future management will be governed increasingly by publicly expressed environmental concerns. Methods of assuring appropriate input in program planning such as formation of the Lower Colorado River Management Program Coordinating Committee were described.

During early stages of the new diversions, the effect of the increased flow in the channel was observed. After a period of years, during which these increased flows will be carried in the Lake Fork Channel, data will be collected which should throw additional light on the processes involved in mountain stream channel adjustment.

Transport characteristics of suspended sediment in the upper San Francisco Bay-Delta system east of San Pablo Bay were discussed. Analysis of the river discharge and suspended solids data (1960-1969) indicated that over 88% of the sediment discharge by the rivers to the Delta originates in the Sacramento River basin. The analysis also indicated that during the November through April period, 80% of the annual sediment discharge from the rivers enters the Delta. Suspended solids transport through the Estuary was primarily controlled by river inflow, export pumping, tidal exchange, two-layered flow estuarine circulation, and surface wave action. A brief summary of sediment discharge to the Bay-Delta Estuary and a general description of the factors influencing transport of sediments through the Estuary were presented.

A byproduct, fly ash, collected from the flue gases of coal burning powerplants will be produced in large quantities. Since bituminous coal fly ash has been used in concrete to considerable advantage for several years now, it is quite likely that similar use could be made of lignite and subbituminous coal fly ashes. If so, this material could provide a plentiful supply of a potentially low cost cementing medium for use with portland cement in concrete. Fly ashes were obtained from five western United States powerplants. A complete chemical and physical analysis of each lignite and subbituminous ash was made, and none was found to meet all requirements for a Class F pozzolan according to Federal Specification SS-P-570b. Concrete mixes were made with 15 and 25% replacement of cement, by weight, with these fly ashes and compared to a mix containing no fly ash and to mixes containing 15 and 25% replacement of fly ash meeting the requirements for a Class F pozzolan. The resulting hardened concrete was found to have adequate compressive strength, reduced drying shrinkage, and satisfactory freeze-thaw durability, but, in some cases, drastically reduced resistance to sulfate attach.

However, its accessibility depends upon proper resolution to conflicting federal, state and Indian claims regarding the distribution of water resources in the area. Indian claims to the water resources stem from treaties entered into with the early European explorers and subsequently ratified by treaties with the United States. Montana and Wyoming , the states composing the Yellowstone River Basin, adhere to the Western Water Law theory that one may appropriate all water passing upon his property provided beneficial use is made of it. State and federal government conflicts center around whether the federal government has delegated to the states the power to regulate the use of water on federal and Indian lands by virtue of statutes permitting appropriations according to state laws and, absent specific delegation, to what extent states may exercise regulatory control over waters that pass through their jurisdictions. Plans for developing coal-related industries in the Yellowstone River Basin should take into account the highly fluctuating water supplies and the needs of those already holding vested water rights. Mistakes in these estimates may prove disastrous for residents. (Moorhouse-Florida) JF - Law and Contemporary Problems Vol. 40, No. 1, p. 77-96, Winter, 1976.

Estimated recoverable petroleum resources for the proposed 206 tract sale area range from 180 to 650 million barrels. Contingent upon actual discovery of this quantity of oil, production is expected to span a period of about 20 years. An oilspill risk analysis was conducted to determine relative environmental hazards of developing oil in the North Atlantic Outer Continental Shelf lease area. The study analyzed probability of spill occurrence, likely path of pollutants from spills, and locations in space and time of recreational and biological resources likely to be vulnerable. These results are combined to yield estimates of the overall oilspill risk associated with development of the lease area.

AN - 17992627; 5257372 AB - In static tests of the toxicity of 2 herbicides, dinoseb (2, 4- dinitro-6-sec-butylphenol) and picloram (4-amino-3, 5, 6- trichloropicolinic acid), to cutthroat (Salmo clarki) and lake trout (Salvelinus namaycush), the 96-h LC50s ranged from 32 to 1,400 {mu}g/liter for dinoseb and from 2,050 to 8,600 {mu}g/liter for picloram. Decreasing pH from 8.5 to 6.5 increased in toxicity of dinoseb by a factor of 43 and decreased that of picloram by a factor of 0.5. Generally, toxicity increased with increasing water temp. Sensitivity of both spp increased with water hardness in tests of dinoseb but was not affected by water hardness in tests of picloram. The toxicity of both chemicals was not changed by aging in water for up to 4wk or by exposing the fish >96h. Rate of yolk sac absorption and growth of lake trout fry was reduced in flow-through tests at concns as low as 0.5 {mu}g/liter dinoseb or 35 {mu}g/liter picloram. Chronic toxicity of both cpds on early life stages of lake trout is more significant than might be anticipated on the basis of only acute tests with fingerlings.

THE METHOD INVOLVED MEASUREMENT OF THE AGI PLUME STRUCTURE AT TWO DOWNWIND DISTANCES FROM THE GROUND GENERATOR(S). DISTANCES BETWEEN THE NINE AVAILABLE PAIRS OF DOWNWIND MEASUREMENT PLANES RANGED FROM APPROXIMATELY 10 TO 100 KM. AN NCAR ACOUSTICAL ICE NUCLEUS COUNTER IN A LIGHT TWIN AIRCRAFT WAS USED TO SAMPLE THE AGI PLUMES. A SERIES OF PASSES WAS MADE THROUGH THE ENTIRE VERTICAL AND HORIZONTAL EXTENT OF THE PLUME AT EACH DOWNWIND DISTANCE. THESE MEASUREMENTS, TOGETHER WITH PILOT BALLOON OBSERVATIONS, PERMITTED CALCULATION OF THE FLUX OF AGI THROUGH EACH VERTICAL CROSS-SECTIONAL PLANE. THE DIFFERENCE IN FLUX MEASUREMENTS YIELDED AN ESTIMATE OF THE PERSISTENCE OF THE SEEDING AGENT OVER THE PERIOD OF TRANSPORT BETWEEN THE TWO VERTICAL PLANES. THIS METHOD WAS APPLIED AT THREE SEPARATE LOCATIONS, DURING DIFFERENT SEASONS, AND WITH VARIOUS DEGREES OF CLOUDINESS. RESULTING ESTIMATES OF DEACTIVATION RATES OF THE ICE NUCLEATING ABILITY OF AGI RANGED FROM NO LOSS TO 70% LOSS PER HOUR. THE IMPLICATIONS FOR POSSIBLE CLOUD SEEDING EFFECTS BEYOND THE INTENDED TARGET AREA WERE DISCUSSED.

INORGANIC WATER QUALITY WAS TAKEN TO REFER TO THE CONCENTRATIONS OF INORGANIC CONSTITUENTS FOUND DISSOLVED IN THE STREAM WATER. NATURAL STREAMS WERE DEFINED AS THOSE STREAMS WHICH ARE FREE OF MAN'S INFLUENCE, ALTHOUGH SOME COMPROMISE OF THIS DEFINITION WAS NECESSARY IN ACTUAL APPLICATION. THE RELATIONSHIP STUDIED WAS THE NEGATIVE CORRELATION BETWEEN INORGANIC WATER QUALITY AND DISCHARGE WHICH IS FOUND IN VIRTUALLY ALL STREAMS. STUDY WAS LIMITED TO 13 INORGANIC CONSTITUENTS.

THE PLANTS WERE DOMINANTLY PONDWEEDS WITH NUMEROUS SUBDOMINANT SPECIES. FILAMENTOUS GREEN ALGAE ALSO COMMONLY GROW AMONG THE WEEDS BUT ARE SELDOM AS DOMINANT AS THEY ARE ON CONCRETE-LINED CANALS. THE MOST SIGNIFICANT DIFFERENCES BETWEEN CANALS SUPPORTING WEEDS AND THOSE THAT DID NOT WERE THAT THOSE WITHOUT WEEDS HAD 70% LESS AVAILABLE NITRATE-NITROGEN, 71% LESS TOTAL IRON, AND 40% LESS TOTAL DISSOLVED SOLIDS. ALL OTHER MEASURED PARAMETERS WERE STATISTICALLY SIMILAR. SMALL STATISTICAL DIFFERENCES OCCURRED IN WATERS THAT HAD GREATER AMOUNTS OF CALCIUM, MAGNESIUM, AND ANIONS OTHER THAN NITRATES BUT THE VARIATIONS BETWEEN INDIVIDUAL IONS WERE SMALL. DISSOLVED OXYGEN LEVELS WERE FOUND TO BE AT SATURATION OR GREATER. FREE CARBON DIOXIDE WAS SELDOM FOUND BECAUSE OF THE GREATER ALKALINITY OF THE WATERS, WHICH HAD PH LEVELS OF 7.4 TO 8.1. THE INDICATIONS ARE THAT MEASURABLE INCREASES OF MINERAL NUTRIENT INPUT WAS THE MAJOR FACTOR IN CAUSING GREATER INCIDENCE OF WEED GROWTH AND SHOULD BE CONSIDERED WHEREVER IRRIGATION RETURN FLOWS AND URBAN SEWAGE EFFLUENTS ENTER IRRIGATION WATERS.

THE SALINITY CONTROL PROBLEM ON THE COLORADO RIVER IS EXAMINED IN RELATION TO THE FEDERAL WATER QUALITY ACT, PL 92-500. EVEN BASIN-WIDE SALINITY CONTROLS AS PRESENTLY ENVISIONED WILL NOT BE ABLE TO MEET ANTICIPATED SALINITY STANDARDS AND THE 'ZERO DISCHARGE' GOALS OF THE ACT. DESCRIBED IS THE COLORADO RIVER WATER QUALITY IMPROVEMENT PROGRAM (CRWQIP), ONLY ONE ELEMENT OF AN ENTIRE MATRIX OF MANAGEMENT PLANS IN THE COLORADO RIVER BASIN. CRWQIP HAS FIVE CATEGORIES OF CONTROL UNDER PRESENT STUDY: RIVER SYSTEM MANAGEMENT; POINT SOURCE CONTROL; DIFFUSE SOURCE CONTROL; IRRIGATION SOURCE CONTROL; AND RETURN FLOW UTILIZATION. OPTIONS THAT MAY BE REQUIRED FOR THE PRESENT NONDEGRADATION POLICY ARE: MINIMIZE DEEP PERCOLATION LOSSES FROM IRRIGATION; DESALT RETURN FLOW AND DIVERT BRINE STREAM FROM THE SYSTEM; DESALT WATER PRIOR TO SELECT USE; DIVERT AND REUSE SALINE FLOWS FOR NONAGRICULTURAL USE; AND COMBINATIONS OF FOREGOING. DISCUSSED IS THE USE OF THE COLORADO RIVER SIMULATION MODEL. A NEW PLANNING STRATEGY OF TOTAL WATER MANAGEMENT IS SUGGESTED TO IDENTIFY AND EVALUATE WATER NEEDS, WATER RESOURCES, PHYSICAL TECHNOLOGY, MANAGEMENT TECHNOLOGY, AND OTHER NONPHYSICAL CONSTRAINTS. THUS, SPECIFIC ECONOMIC LIMITATIONS AND INSTITUTIONAL CONSTRAINTS IDENTIFIED UNDER THE VARIOUS MANAGEMENT OPTIONS WILL ASSIST IN SETTING ATTAINABLE SALINITY LEVELS WITHIN A RIVER BASIN IN LIEU OF MEETING RIGID ZERO DISCHARGE LIMITATIONS FOR EACH USER. SYSTEMS ANALYSIS TOOLS ARE ADVOCATED FOR COMPREHENSIVE BASINWIDE MANAGEMENT.

The gate members are oppositely rotatable through an arc of approximately 90 deg between an open position and a closed position just downstream of the outlet. In the closed position, the gate members are closed together along a lip seal at the center of the conduit. A collar seal, mounted to the conduit, is urged against the gate members to block peripheral fluid discharge from the outlet. When the gate is fully or partially open, a portion of the outlet extends downstream of the lip seal to minimize ' fan out ' of the discharge. In the fully open position, the gate members are open symmetrically beyond the diameter of the outlet for unrestricted fluid discharge through the outlet. The gate members are pivotally attached to trunnion members at each side of the conduit through support arm plates. In one embodiment, the support arm plates contain elongated slots approximately perpendicular to the gate members that act as cam surfaces for controlling rotation of the gate members. Rotation of the gate members is caused by longitudinal movement of control shafts, guided by the trunnion members. The shafts are connected to follower pins that ride the elongated slots in the support arm plates to provide the camming action. This arrangement produces a closing torque that progressively increases during closure of the gate members.

To better exploit the rapid startup potential, the latitudes and constraints of synchronizing are examined and means are developed to expedite the synchronizing process. A special synchronizer is developed with compensation for acceleration and with sensitivity to residual voltage. By this means, transients of induction synchronizing are reduced, pull-in torque may be increased, and full voltage synchronizing may be achieved at higher acceleration and in less time for start up of emergency standby units.

This investigation was conducted within the Bureau 's Colorado River Basin Weather Modification Program, with primary emphasis away from the demonstration and testing of the LANDSAT Data Collection System toward its use as an operational tool in monitoring weather conditions for cloud seeding control. Five LANDSAT Data Collection Platforms were operated during the reporting period and proved to be reliable weather resistant units suitable for the collection of hydrometeorological data from remote, severe winter environments. The data relayed by LANDSAT satellite were available in near real-time for project forecasting. A significant accomplishment toward improving the LANDSAT DCS was the development of a system for averaging wind speed and wind direction data and on-site storage of hourly averaged data.

The paper begins with a history review and then considers plan formulation, formulation to emphasize national economic development evaluation, environmental quality evaluation, regional development evaluation, evaluation of social factors, cost allocations, and the coordination and review of planning studies. It is concluded that new or improved procedures are needed in every area that demands the characteristics of multi-objectives, externalities, social values, etc. All effects, tangible and intangible, primary and secondary, on the multi-objectives need to be evaluated and considered in planning for water resources development.

It considers multiple use planning with its variety of objectives as synonomous with multiple objective planning; the Water Resources Council (WRC) Principles and Standards are merely evaluation procedures that can be applied to evaluating the effectiveness of its multiple use planning system. Only recently has the Bureau become seriously involved in trying to apply the WRC standards to evaluating its land management practices. It now plans to test the standards for evaluating its land management programs, and a team has been assigned to test the procedures on specified activities in Oregon and New Mexico. It is anticipated that procedures will be developed from these tests for Bureau-wide implementation of the WRC standards in its planning system. This paper considers the Bureau 's involvement in multiple use (multiple objective) planning to date; the paper attempts to outline the history of planning in the Bureau, current status and components of the planning system, and some deficiencies that have been noted.

SEVERAL TECHNIQUES FOR EVALUATION ARE PROPOSED. AESTHETIC OPPORTUNITY IS RELATED TO THE RELATIVE STATE OF PHYSIOLOGICAL AND PSYCHOLOGICAL SECURITY ENJOYED BY AN INDIVIDUAL. CONSIDERED ARE HUMAN DEVELOPMENT AND GROWTH IN TERMS OF NEEDS AND GOALS. WHETHER OR NOT MAN IS CONSCIOUSLY CONCERNED ABOUT THE AESTHETICS OF HIS ENVIRONMENT, HE IS SEARCHING FOR MEANING, COHESION, AND ORDER IN HIS SURROUNDINGS. PREDICTABILITY AND RELATIVE COMPLEXITY ARE ENVIRONMENTAL QUALITIES WHICH INFLUENCE WHETHER OR NOT A PERSON HAS AN OPPORTUNITY FOR AN AESTHETIC EXPERIENCE. WITH ORDER AND COMPLEXITY BEING ESSENTIAL ENVIRONMENTAL ELEMENTS, IT IS ASSUMED THAT QUANTIFICATION OF THESE ELEMENTS COULD LEAD TO THE DEVELOPMENT OF AN ANALYTICAL PREDICTIVE MODEL FOR RESOURCE DECISION-MAKING. IT IS RECOMMENDED THAT THE SOCIAL AND BEHAVIORAL SCENCES BECOME AN INTEGRAL PART OF RESOURCE OR ENVIRONMENTAL MANAGEMENT, SINCE SOCIAL WELFARE CAN BE ACHIEVED ONLY WHEN MAN BEGINS TO PLAN, DEVELOP, AND MANAGE WITH THE ENVIRONMENT AND HIMSELF AS A COLLECTIVE ENTITY.

WATER QUALITY PROBLEMS ALSO EXIST IN THE IMPERIAL VALLEY, CALIFORNIA, BECAUSE OF THE PRESENCE OF HIGHLY SALINE SOILS AND MANY SALINE SPRINGS WHICH ADD SIGNIFICANT QUANTITIES OF SALT TO THE RIVER. GEOTHERMAL SOURCES STORED IN THE FORM OF A HOT BRINE UNDERGROUND IN THE IMPERIAL VALLEY HAVE THE POTENTIAL TO YIELD ECONOMICAL NEW SUPPLIES OF FRESH WATER BY DESALTING AND ALSO TO YIELD MINERAL BY-PRODUCTS AND THE PRODUCTION OF ELECTRICITY. A PROGRAM FOR WATER PRODUCTION FROM THE GEOTHERMAL RESOURCES CONSISTS OF THREE PROPOSED STAGES: THE RESEARCH AND DEVELOPMENT STAGE; THE DEMONSTRATION STAGE; AND, THE LARGE-SCALE DEVELOPMENT STAGE. THE RESEARCH AND DEVELOPMENT STAGE IS NOW IN PROGRESS AND INCLUDES EXTENSIVE GEOLOGICAL, GEOPHYSICAL, AND WATER CHEMISTRY INVESTIGATIONS TO DETERMINE THE POTENTIAL AND EXTENT OF THE GEOTHERMAL RESOURCE. THE DEMONSTRATION STAGE WOULD SHOW THE VIABILITY OF LARGE-SCALE DEVELOPMENT. THE LARGE-SCALE DEVELOPMENT STAGE IS THE FULLY OPERATIONAL STAGE WHICH COULD AUGMENT THE COLORADO RIVER BY SEVERAL MILLION ACRE-FEET OF DESALTED WATER ANNUALLY AND WOULD HAVE AN ASSOCIATED ELECTRIC POWER PRODUCTION. INVESTIGATIONS COMPLETED INCLUDE THE DRILLING OF TWO GEOTHERMAL WELLS, ONE TO 8030 FEET AND THE OTHER TO 6005 FEET AND THE INSTALLATION OF TWO DESALTING TEST UNITS, A MULTISTAGE FLASH UNIT AND A VERTICAL TUBE EVAPORATOR. THE PROPOSED NEXT STEP IS THE CONSTRUCTION OF A PILOT PLANT CAPABLE OF PROCESSING 200,000 TO 500,000 GALLONS PER DAY.

SALINITY CONTROL IN THE COLORADO RIVER BASIN, WHEN INTEGRATED INTO AN OVER-ALL BASIN MANAGEMENT PLAN, CAN PREVENT THE COSTLY INCREASES IN SALINITY ANTICIPATED FROM CONTINUING ECONOMIC GROWTH IN THE BASIN. TO BE IMPLEMENTABLE, THE PLAN WILL NEED TO BE SOCIALLY, POLITICALLY, ECONOMICALLY, AND ECOLOGICALLY ACCEPTABLE AS WELL AS PHYSICALLY SOUND. IN THE COLORADO RIVER SYSTEM, THE BASIN MANAGEMENT CONCEPT PROVIDES A MORE VIABLE APPROACH TO SALINITY CONTROL THAN SINGULAR APPLICATION OF THE COMPLETE WATER REUSE CONCEPT.

THE INCREASING DIVERSIONS AND CONSUMPTIVE USES ARE INCREASING THE NATURAL SALINITY LEVELS. TO ANALYZE THIS PROBLEM AND TO ASSIST IN PLANNING SALINITY ALLEVIATION MEASURES, A BASIN SIMULATION MODEL HAS BEEN DEVELOPED. THIS ARTICLE DISCUSSES THE MODEL IN TERMS OF GENERAL CAPABILITY AND OPERATION, RELATIONSHIPS WITH BASIN FEATURES, HYDROLOGICAL RELATIONSHIPS, AND SALINITY ROUTING. THIS APPROACH ALLOWS THE OPERATOR TO INTERACT WITH THE SYSTEM AND UTILIZE HIS EXPERIENCE AND INTUITION, THEREBY SOLVING EFFICIENTLY COMPLEX PROBLEMS PERTAINING TO RIVER BASINS.

POPULATION DATA SHOWED FEW DIFFERENCES BETWEEN CANALS TREATED OR UNTREATED WITH HERBICIDES. CANALS TREATED WITH COPPER SULFATE-XYLENE SHOWED SPECIES DIVERSITY DECLINES BUT RECOVERED RAPIDLY AFTER TREATMENT STOPPED. MACROINVERTEBRATES DECREASED AFTER XYLENE TREATMENT, RETURNED FOUR DAYS AFTER TREATMENT, AND REACHED PREVIOUS DIVERSITY LEVELS IN ONE MONTH; DIATOMS RECOVERED MORE SLOWLY. RELATIONSHIPS BETWEEN TAXA DIVERSITY INDICES AND STANDING CROP BIOMASS WERE MORE SIGNIFICANT FOR DIATOMS THAN MACROINVERTEBRATES. NITRATE-NITROGEN WAS HIGHER IN CANALS WITH WEED GROWTH. TAXA TYPE AND COMMUNITY STRUCTURE WERE INDICATORS OF CANAL-RIVER HABITATS. ADENOSINE TRIPHOSPHATE WAS NOT A RELIABLE INDICATOR OF LIVING BIOMASS; HOWEVER GRAVIMETRIC BIOMASS DETERMINATION MAY BE LESS SINSITIVE THAN METABOLIC ADENOSINE TRIPHOSPHATE IN DETERMINING BIOLOGICAL PRODUCTIVITY. SPECIES DIVERSITY INDICES AND CHEMICAL AND PHYSICAL WATER ANALYSES CAN INDICATE IF PESTICIDES ARE HARMING THE HABITAT. EVALUATION OF AN EXPERIMENTAL ACETAMIDE-METHYLUREA COMPOUND AND MONOCHLOROTOLUENE INDICATED THAT THEY WERE HERBICIDAL TO PONDWEEDS. A MIXTURE OF THREE SOLUBLE COPPER COMPOUNDS WITH DIQUAT HAD MORE HERBICIDAL ACTIVITY THAN COPPER SULFATE-DIQUAT. STUDIES OF HERBICIDE EFFECTS OR ADENOSINE TRIPHOSPHATE LEVELS ON PONDWEEDS AND ALGAE WERE USEFUL IN DETERMINING HERBICIDE EFFICACY.

COMPUTER OPERATED CONTROLLERS APPEAR TO HAVE ADVANTAGES FOR THESE INTERFACES. BY PLACING ATTENTION ON MORE THAN ONE METHOD OF DEVELOPING CONTROLS IT IS FELT THAT RAPID PROGRESS CAN BE MADE IN REACHING THE STATED GOAL OF IMPROVED SERVICE TO WATER USERS WITH LESS WASTE AND AT A CHEAPER COST OF OPERATION.

THE WEIR IS LOCATED SEVERAL MILES UPSTREAM FROM SACRAMENTO AND IS THE ONLY ONE OPERATED AT HIGH STAGES TO MAINTAIN A 29.0-FT. MAXIMUM STAGE AT THE SACRAMENTO 'I' STREET GAGE. HIGH INFLOW FROM THE REGULATED AMERICAN RIVER BETWEEN THE WEIR AND THE GAGE OFTEN CAUSES FLOW TO REVERSE IN A PORTION OF THE SACRAMENTO RIVER, BUT THIS COMPLICATION IS EASILY HANDLED BY THE METHOD OF CHARACTERISTICS. ALTHOUGH THE GATE-STROKING TECHNIQUE IS EXTENDED TO OPERATION OF THE SACRAMENTO WEIR, THE SAME EXTENSION CAN BE MADE TO NATURAL AND ARTIFICIAL CHANNELS IN WHICH A CONTROL STRUCTURE IS LOCATED. THE THREE SECTIONS ANALYZED ARE: (1) BASIC THEORY OF UNSTEADY FLOW AND THE DEVELOPMENT AND APPLICATION OF THE CHARACTERISTIC EQUATIONS; (2) THE GEOMETRY OF THE LOWER SACRAMENTO RIVER; AND (3) TRANSIENT CONTROL OF THE LOWER SACRAMENTO RIVER. THE GATE OPERATION TECHNIQUE ALLOWS THE DETERMINATION OF WHETHER FLOOD CONDITIONS NOW DEVELOPING IN THE SACRAMENTO OR RELEASE SCHEDULES ANTICIPATED FROM UPSTREAM DAMS CAN BE CONVEYED WITHIN THE SYSTEM WITHOUT VIOLATING THE PROJECT FLOOD PLAIN. FURTHERMORE, EXTENSION OF THIS TYPE OF SCHEME COULD PERMIT THE INTERNAL OPTIMIZATION OF RELEASE SCHEDULES AND WEIR OPERATION SUCH THAT THE OPERATION OF THE CONVEYANCE SYSTEM IS OPTIMIZED. INCLUDED IS AN APPENDIX WITH MORE DETAILED TREATMENT ON DEVELOPMENT OF THE UNSTEADY AND CHARACTERISTIC EQUATIONS.

PARTICULAR CONCERN IS FOCUSED ON THE ARID AND SEMI-ARID WESTERN STATES. AFTER EXAMINING THE LEGAL HISTORY OF INDIAN RIGHTS, THE AUTHOR CONCLUDES THAT THE POLICE POWER OF THE STATES MAY NOT BE EXTENDED TO AFFECT INDIAN WATER RIGHTS. SEVERAL REASONS SUPPORT THIS CONCLUSION: (1) THE UNBROKEN LINE OF DECISIONAL LAW; (2) THE WILL OF CONGRESS EXPRESSED IN THE ENABLING ACTS ADMITTING WESTERN STATES INTO THE UNION; (3) THE CONSTITUTIONAL DISCLAIMERS IMPOSED AS CONDITIONS TO STATE ADMISSION (UNDER WHICH THE STATES RENOUNCED ALL CLAIMS TO INDIAN LANDS); AND (4) THE OVERRIDING TRUST OBLIGATION OF THE UNITED STATES TO PRESERVE AND PROTECT THE 'INDIAN WINTERS DOCTRINE' RIGHTS TO THE USE OF WATER IN THE ARID AND SEMI-ARID WEST. THE AUTHOR STATES THAT THE PRIMARY REASON FOR THE VIOLATION OF INDIAN RIGHTS BY THE STATES HAS BEEN THE AVIDITY FOR WATER IN THE WESTERN STATES AND THE FAILURE OF THE UNITED STATES TO PREVENT THOSE VIOLATIONS.

THESE EFFECTS ARE DERIVED FROM TWO GENERAL SOURCES: (1) THE IMMEDIATE IMPACT FROM CONSTRUCTION ACTIVITY; AND (2) RECURRING SOCIAL, ENVIRONMENTAL, AND ECONOMIC IMPACTS FROM PROJECT OPERATION. CONSTURCTION ACTIVITY CREATES A DEMAND FOR A LARGE VARIETY OF PRODUCTS AND SERVICES THAT AFFECT MANY INDUSTRIES AND A WIDE NUMBER OF OCCUPATIONAL GROUPS. ONCE CONSTRUCTION IS COMPLETED AND PROJECTS GO INTO SERVICE, THEY GENERATE A STEADY STREAM OF ANNUAL MONETARY AND NONMONETARY BENEFITS. OTHER POSITIVE IMPACTS ON THE SOCIAL AND ENVIRONMENTAL QUALITY OF LIFE ARE MADE THROUGH ENHANCEMENT OF RECREATIONAL POTENTIALS, FISH AND WILDLIFE HABITAT, AND IMPROVED PUBLIC SERVICES. A TOTAL FEDERAL INVESTMENT OF $5.5 BILLION IN COMPLETED PROJECT FACILITIES DURING THE LAST 70 YEARS HAS RESULTED IN A NET INCREASE IN ECONOMIC ACTIVITY OF $4.3 BILLION EACH YEAR TO THE NATION. DEVELOPMENT OF HYDROELECTRIC POWER LED TO THE ESTABLISHMENT OF MAJOR ALUMINUM AND PHOSPHATE INDUSTRIES. AVAILABILITY OF IRRIGATION WATER HAS GREATLY IMPROVED THE ECONOMY OF MANY STATES, FOR EXAMPLE, NEBRASKA.

IN ADDITION TO ARGICULTURE, WATER-ORIENTED RECREATIONAL ACTIVITIES, AND OTHER MULTIPURPOSE FUNCTIONS, WATER IS VITAL TO EXPANSION OF EXISTING INDUSTRIES. THE DEVELOPMENT OF NEW INDUSTRIES IS OFTEN LIMITED IN AREAS THAT LACK THE NECESSARY WATER SUPPLIES. IT IS EXPECTED THAT UNITED STATES ENERGY NEEDS WILL BE MET FROM SEVEN SOURCES OF SUPPLY IN 1985. OIL, NATURAL GAS, COAL, AND HYDROELECTRIC POWER ARE CONTRIBUTORS OF LONG STANDING. NUCLEAR, SHALE OIL, AND SYNTHETIC COAL-GAS PRODUCTS ARE RELATIVE NEWCOMERS TO THE MARKET. AN EXPANSION COMPARABLE TO MORE THAN HALF OF THE EXISTING CAPABILITY OF THE PETROLEUM OR NATURAL GAS INDUSTRIES IN 1970 WILL REQUIRE TECHNOLOGICAL ADVANCES, HUGE CAPITAL INVESTMENTS, AND FEDERAL AND STATE COOPERATION WITH PRIVATE INDUSTRY. INTEREST APPEARS TO BE IN USING COAL IN A DUAL-ENERGY CAPACITY. IT CAN BE CONVERTED TO ELECTRICAL ENERGY OR SYNTHETIC HYDROCARBONS, GASOLINE, AND NATURAL GAS SUBSTITUTES. WATER IS NECESSARY TO MEET THIS TECHNOLOGICAL DEVELOPMENT. MANY INTERESTING AND COMPLEX SOCIOECONOMIC AND ENVIRONMENTAL FACTORS AS WELL AS ADMINISTRATIVE INTERACTIONS OF FEDERAL, STATE, AND LOCAL GOVERNMENTS AND THE PRIVATE SECTOR WERE DISCUSSED.

THE PROGRAM OBJECTIVE IS TO DEMONSTRATE THE COMPATIBILITY OF BENEFICIAL REUSE AND TREATMENT OF MUNICIPAL AND INDUSTRIAL WASTEWATER WITH MARSH MANAGEMENT. THE PROGRAM IS DESIGNED TO PROVIDE INFORMATION TO ASSIST THE LOCAL AREA IN MEETING ITS WASTE TREATMENT AND DISPOSAL OBLIGATIONS, TO PROVIDE INFORMATION ON THE REUSE OF WASTEWATER FOR AGRICULTURAL PURPOSES, AND TO PROVIDE THE BUREAU OF RECLAMATION WITH INFORMATION ON A SOURCE OF WATER FOR MEETING ITS RESPONSIBILITY FOR PROTECTION OF THE SUISUN MARSH. THE PROGRAM EVALUATES SEVERAL FEATURES WHICH BENEFICIALLY USE WASTEWATER AND ALSO REMOVE NITROGEN. FIELD FACILITIES INCLUDE A DETENTION RESERVOIR, A SPRINKLER-IRRIGATED AND TILE-DRAINED PASTURE, MARSH PONDS, AND IRRIGATED MARSHLAND. THE FACILITIES ARE DESIGNED TO REMOVE 90% OF THE NITROGEN FROM THE WASTEWATER THAT EVENTUALLY FLOWS TO THE MARSH CHANNELS.

TO HANDLE THIS INCREASE WORKLOAD, AN ENVIRONMENTAL STAFF WAS ESTABLISHED IN 1970-71 INFUSING THE BUREAU WITH AFFIRMATIVE ENVIRONMENTAL STANCES. THE COST OF AN ENVIRONMENTAL IMPACT STATEMENT AVERAGES OVER $25,000 AND TAKES OVER EIGHT MONTHS PREPARATION. THE PROCESS OF ENVIRONMENTAL REVIEW, STATEMENT PREPARATION, AND PUBLIC REVIEW HAS A DIRECT IMPACT IN MODIFYING AND/OR CANCELLING A NUMBER OF THE BUREAU'S PROPOSED PROJECTS.

CONSIDERED IS THE STUDY AND DEVELOPMENT OF GEOTHERMAL RESOURCES, FOCUSING ON THE NECESSITY FOR BROAD INTERDISCIPLINARY ANALYSIS. TO RELATE THE NEED FOR AN INTERDISCIPLINARY APPROACH TO A SPECIFIC CASE, THE BUREAU OF RECLAMATION'S GEOTHERMAL RESOURCES INVESTIGATION IN IMPERIAL VALLEY, CALIFORNIA IS DESCRIBED. IN THE IMPERIAL VALLEY, AND IN THE VAST MAJORITY OF KNOW GEOTHERMAL DEPOSITS, HEAT IS STORED AS HOT FLUID, PROVIDING THE POTENTIAL FOR ECONOMICAL NEW SUPPLIES OF FRESH WATER THROUGH DESALTING, CONCURRENT WITH THE PRODUCTION OF ELECTRICITY. THE BUREAU'S CONCEPT FOR DEVELOPMENT HERE INVOLVES THREE STAGES. STAGE ONE WOULD, THROUGH EXTENSIVE GEOLOGICAL, GEOPHYSICAL, AND WATER CHEMISTRY INVESTIGATIONS, DETERMINE THE POTENTIAL AND EXTENT OF THE GEOTHERMAL RESOURCE. STAGE TWO WOULD DEMONSTRATE THE FEASBILITY OF A LARGE-SCALE DEVELOPMENT. IN THE THIRD STATE, LARGE-SCALE DEVELOPMENT, THE FLOWS OF THE COLORADO RIVER WOULD BE AUGMENTED BY AS MUST AS 2.5 MILLION ACRE-FEET OF DESALTED WATER ANNUALLY WITH ELECTRIC POWER PRODUCTION OF ABOUT 10,000 MEGAWATTS. CONSIDERED IS THE BROAD SPECTRUM OF TECHNICAL, ENVIRONMENTAL, AND SOCIAL FACTORS INVOLVED IN SUCH A DEVELOPMENT PLAN. A LEAD AGENCY CAN CONTINUALLY COORDINATE THE COMPREHENSIVE, INTERDISCIPLINARY INPUT. THUS, A TRUE EVALUATION CAN BE MADE OF THE CUMULATIVE IMPACTS RESULTING FROM GEOTHERMAL RESOURCE DEVELOPMENT. INSIGHTS FROM ALL DISCIPLINES ARE ESSENTIAL FOR MOST EFFECTIVE DEVELOPMENT AND FOR A REALISTIC AND COMPREHENSIVE PERSPECTIVE OF ALTERNATIVES.

THE FIRST STEP, ASSUMING THAT DEVELOPMENT AND UTILIZATION OF NATURAL RESOURCES IN THESE AREAS IS DESIRABLE, WOULD BE THE FORMATION OF A POSITIVE PUBLIC POLICY DIRECTED TOWARD PROVIDING MORE ADEQUATELY FOR PEOPLE IN THESE DRY AREAS. AN INVENTORY OF THE HUMAN RESOURCES AS WELL AS THE TYPE AND AMOUNTS OF WATER RESOURCES PRESENT IS ALSO NECESSARY. A CRITICAL FACTOR IS WHAT TYPE OF DEVELOPMENT SYSTEM WILL BE USED TO AUGMENT WATER SUPPLIES. ALTERNATIVES MIGHT INCLUDE CONVENTIONAL STORAGE AND CONVEYANCE FACILITIES, WEATHER MODIFICATION, SEA OR BRACKISH WATER CONVERSION, GEOTHERMAL WATER PRODUCTION, INCREASING EFFICIENCIES OF PRESENT SYSTEMS OF GROUND AND SURFACE WATER SUPPLIES, AND TRANSBASIN WATER DIVERSION. TRENDS INDICATE A RAPIDLY INCREASING AMOUNT OF MALNUTRITION AND HUNGER WILL PREVAIL PLACING GREATER DEMANDS FOR WORLD FOOD PRODUCTION. WATER DEVELOPMENT IN ARID AREAS IS POSSIBLE WITH PRESENT TECHNOLOGIES, AND CONSIDERATION SHOULD BE GIVEN TO DEVELOPMENT OF THESE AREAS TO PREVENT MIGRATION TO THE ALREADY OVERBURDENED POPULATION CENTERS AND AS A MEANS OF INCREASING WORLD FOOD SUPPLIES.

This decrease may correlate with increased pumpage in the artesian Floridan aquifer which underlies the mainland. In a cooperative project with the United Nations Development Program and the Jamaica Geological Survey Department, the National Aeronautics and Space Administration took more than 17,000 frames of color and infrared color photography of Jamaica and its coastal waters in April 1971. Submarine springs on the north-central coast of Jamaica discharge primarily clear water from karstic limestone and were not discernible in the aerial photos. In contrast, submarine springs on the south coast discharge from sand and gravel aquifers and turbidity plumes are clearly visible in photographs. A significant anomaly was discovered in infrared imagery of the northeast coast of the island after the field investigation was completed. The anomaly is presumed to be evidence of submarine ground-water discharge.

THEORETICAL EQUATIONS OF THE PROCESS WERE DEVELOPED AND CHECKED BY THE MODEL STUDY. THESE EQUATIONS WERE APPLIED TO FIELD DATA FROM WELLTON-MOHAWK DIVISION, GILA PROJECT, ARIZONA, TO PREDICT FUTURE CHANGE IN SALINITY OF THE DRAINAGE EFFLUENT. HYDRAULIC MODEL STUDIES VERIFIED THE FORM OF THE EXPONENTIAL EQUATION WHICH DESCRIBES THE CHANGE IN SALINITY OF THE PUMPED EFFLUENT FROM AN AQUIFER INITIALLY FILLED WITH SALINE WATER OF HIGHER CONCENTRATION THAT THE REPLACEMENT IRRIGATION DEEP PERCOLATION WATER. ASSUMING THAT THE PUMPING OPERATION IN THE WELLTON-MOHAWK DIVISION WILL CONTINUE IN A PATTERN SIMILAR TO THAT FROM 1966 THROUGH 1972, THE AVERAGE SALINITY OF THE DRAINAGE EFFLUENT WILL DECREASE EXPONENTIALLY. SALT CONCENTRATION MEASUREMENTS MADE IN THE WELLTON-MOHAWK MAIN CONVEYANCE CHANNEL ARE THE BEST SOURCE OF DATA FOR DETERMINATION OF THE WEIGHTED AVERAGE SALINITY EFFLUENT CONDITIONS. THESE DATA WERE USED TO PREDICT FUTURE AVERAGE SALINITY VALUES FOR WELLTON-MOHAWK DRAINAGE FLOWS. A SYSTEM'S ANALYSIS STUDY HAS BEEN MADE AND A 'DRAINAGE OPERATIONS SCHEDULING MODEL' DEVELOPED.

APPROXIMATELY 50 CASE HISTORIES OF RIPRAP SLOPE PROTECTION WERE STUDIED. ECONOMICS OF PROVIDING UPSTREAM SLOPE PROTECTION, INCLUDING ORIGINAL AND LIFETIME MAINTENANCE COSTS, IS THE PREDOMINANT FACTOR IN SELECTING, DESIGNING, AND CONSTRUCTING THE UPSTREAM SLOPE PROTECTION. ALTHOUGH EXPERIENCE INDICATES THAT ROCK FRAGMENTS LARGER THAN 1 CU YD WOULD BE REQUIRED ON MANY BUREAU EARTH/DAM STRUCTURES TO PROTECT SLOPES AGAINST OCCASIONAL SEVERE STORMS, FEW ROCK SOURCES CAN PROVIDE FRAGMENTS OF THAT SIZE. HENCE, A 36-INCH BLANKET OF RIPRAP GRADED UP TO 1 CU YD IS CONSIDERED THE MAXIMUM PROTECTION THAT CAN BE REASONABLY OBTAINED. SPECIFICATIONS SHOULD BE REVISED TO INCLUDE: (1) A GRADATION THAT CONTAINS MORE OF THE LARGER SIZES, (2) STRICTER PLACING REQUIREMENTS TO OBTAIN/A DENSER RIPRAP BLANKET, (3) GREATER SELECTIVITY OF QUARRY MATERIAL, AND (4) CLOSER CONTROL OF QUARRY BLASTING TECHNIQUES. DETAILED INSTRUCTIONS TO INVESTIGATORS OF RIPRAP SOURCES ARE INCLUDED. (WOODARD-USGS) JF - AVAILABLE FROM NTIS, SPRINGFIELD, VA. 22151 AS PB-219 834; PRICE $3.00 PRINTED COPY; $1.45 MICROFICHE.

THE LANDSLIDE DAMAGED THE PARTIALLY CONSTRUCTED SPILLWAY AND FORCED THE CONTRACTOR TO ALTER HIS INITIAL PLANS. USING A SCALE MODEL, A DESIGN WAS DEVELOPED FOR A NEW SPILLWAY STRUCTURE. AN ELBOW WAS CONSTRUCTED FOR THE SPILLWAY CONDUIT AND MAJOR CONSIDERATION HAD TO BE GIVEN TO THE DESIGN OF A STILLING BASIN DUE TO THE UNSYMMETRICAL APPROACH OF THE FLOW RESULTING FROM THE CIRCULAR CURVE IN THE UPSTREAM CONDUIT. BY USING VARIOUS COMBINATIONS OF BAFFLE BLOCKS, A SUITABLE REALIGNMENT OF THE SPILLWAY WAS DETERMINED IN LABORATORY TESTS. THE NEW SPILLWAY DESIGN WAS USED WITHOUT MUCH DELAY IN CONSTRUCTION TIME. TO IMPROVE THE STABILITY OF THE LANDSLIDE MATERIAL, A PLAN WAS DEVELOPED TO PROVIDE FOR DRAINAGE AND FOR BUTTRESSING THE TOE OF THE SLIDE MASS BY ADDING GRAVEL AND COBBLE FILL MATERIAL AT THE BASE.

ENVIRONMENTAL ALTERNATIVES MUST BE ACCEPTABLE, EFFECTIVE AND EFFICIENT AS WELL AS REPRESENTATIVE OF RECOGNIZED PRACTICES IN THE SOCIAL, NATURAL AND PHYSICAL SCIENCES FOR FORMULATION OF PLANS. THE 1968 COLORADO RIVER BASIN PROJECT ACT CONDUCTED TWO INTERRELATED STUDIES: (1) TO DETERMINE THE FEASIBILITY OF AUGMENTING SUPPLIES OF THE COLORADO RIVER; AND (2) TO DEVELOP COMPREHENSIVE RECONNAISSANCE PLANS TO MEET WATER NEEDS OF THE 11 STATES WEST OF THE CONTINENTAL DIVIDE. ENVIRONMENTAL PLANNING ENTAILS SEVERAL STEPS AS DESCRIBED BY THE WATER RESOURCES COUNCIL: (1) IDENTIFICATION OF EXISTING AND PROJECTED PROBLEMS; (2) EVALUATION OF RESOURCE CAPABILITIES AND FUTURE CONDITIONS; (3) FORMULATION OF ALTERNATIVE PLANS TO ACHIEVE VARYING LEVELS OF CONTRIBUTIONS TO THE ENVIRONMENTAL QUALITY OBJECTIVE; (4) EVALUATION OF DIFFERENCES AMONG ALTERNATIVE PLANS; AND (5) A SELECTION OF A RECOMMENDED PLAN OF ACTION FROM AMONG ALTERNATIVES DEVELOPED AND ANALYZED, BASED ON THE EVALUATION OF THE TRADEOFFS AMONG THE VARIOUS OBJECTIVES. AN INTERIM EVALUATION DEVICE HAS BEEN DEVELOPED BY THE MANAGEMENT TEAM OF THE WESTERN U.S. WATER PLAN STUDY. CRITERIA USED TO EVALUATE AND DESCRIBE ENVIRONMENTAL CONDITIONS ARE: QUANTITY, QUALITY, HUMAN INFLUENCE, UNIQUENESS, MAGNITUDE AND SIGNIFICANCE. THESE FACTORS PROVIDE PERSPECTIVES ON RELATIVE AVAILABILITY OF THE RESOURCE CATEGORY WITHIN THE PLANNING SETTING, AND PROVIDES MAXIMUM ECONOMIC EFFICIENCY FOR ENVIRONMENTAL PLANNING.

RELATIONSHIPS AMONG SOIL-WATER SUCTION, PLANT-WATER SUCTION, AND CAMBIAL ACTIVITY OF DOUGLAS-FIR (PSEUDOTSUGA MENZIESII (MIRB.) FRANCO) WERE ALSO EVALUATED. SOIL-WATER CONTENT WAS MEASURED WITH GYPSUM BLOCKS. PLANT-WATER SUCTION OF DOUGLAS-FIR BRANCH TIPS WAS MEASURED WITH A PRESSURE BOMB. THESE MEASUREMENTS WERE TAKEN EARLY IN THE MORNING AT LEAST ONCE EVERY 10 DAYS. EXPERIMENTALS SITES WERE SELECTED ON 3 SOIL SERIES AND 1 NORTH SLOPE SOIL PHASE TENTATIVELY CLASSIFIED AS XERIC AND ON 4 SOIL SERIES TENTATIVELY CLASSIFIED AS UDIC. THE 4 STUDY SITES IN THE XERIC ZONE HAD SOIL-WATER SUCTIONS EQUAL TO OR GREATER THAN 15 BARS WITHIN THE SOIL-WATER CONTROL SECTION FOR AT LEAST 60 CONSECUTIVE DAYS. NONE OF THE 4 STUDY SITES IN THE UDIC ZONE WERE DRY THAT LONG. CUMULATIVE WATER DEFICIT IN THE XERIC ZONE WAS ABOUT 75% OF THE SEASONAL TOTAL WHEN THE ENTIRE SOIL-WATER CONTROL SECTION ATTAINED 15 BARS. ALMOST ALL AVAILABLE WATER WAS REMOVED FROM THE UPPER THIRD OF THE PROFILE IN THE XERIC ZONE WHEN THE TREES STOPPED PRODUCING SPRINGWOOD. MUCH LESS WATER WAS REMOVED FROM THE UPPER THIRD OF THE PROFILE IN THE UDIC ZONE. THE SAME RELATIONSHIP HELD TRUE FOR THE AVAILABLE WATER IN THE ENTIRE PROFILE AT TIME OF DORMANCY. TREES IN THE XERIC ZONE PRODUCED SPRINGWOOD OF 23 MORE DAYS AND HAVE 26 MORE DAYS TOTAL GROWING TIME THAN TREES IN THE UDIC ZONE. CHANGES OF SOIL AND PLANT-WATER SUCTION WITH TIME SHOWED SIMILAR PATTERNS BUT DIFFERENT MAGNITUDES.

A KEY ELEMENT FOR SUCCESS IS THE REORIENTATION OF PHILOSOPHIES TO RECOGNIZE THAT RETAINING OR RESTORING NATURAL APPEARANCES, OR THE BLENDING OF MAN MADE WORKS WITH NATURE, IS A FULL-FLEDGED OBJECTIVE IN RESOURCE DEVELOPMENT AND USE. RESERVOIRS PROVIDE MANAGEMENT WITH CONSIDERABLE OPPORTUNITY TO USE IMAGINATION AND INGENUITY FOR ENVIRONMENTAL ENHANCEMENT. CAREFUL ATTENTION IS GIVEN TO MAINTAINING OPTIMUM WATER LEVELS WITHIN PERMISSIBLE OPERATING LEVELS DURING SPRING FISH-SPAWN PERIODS AND WATERFOWL NESTING SEASONS TO ENHANCE WILDLIFE PROPAGATION. SEDIMENT DEPOSITS IN RESERVOIR AREAS WHICH MAY BE UNCOVERED AND BARREN IN PERIODS OF LOW WATER HAVE BEEN TREATED WITH VEGETATION PLANTINGS ESTABLISHED FOR SOIL STABILIZATION, TO PREVENT DUST FROM BLOWING, AND FOR WILDLIFE ENHANCEMENT. FOR WATER DISTRIBUTION SYSTEM MANAGEMENT, PUMPING PLANTS MAY BE INVOLVED IN DELIVERING WATER INTO THE DISTRIBUTION SYSTEM, OR IN CONVEYING WATER THROUGH THE SYSTEM. MEANS USED TO ACHIEVE IMPROVEMENTS IN WATER DISTRIBUTION ARE AUTOMATION OF THE WATER SYSTEMS TO IMPROVE EFFICIENCIES, REHABILITATION OF OLDER WATER SYSTEMS TO SAVE WATER, ENFORCEMENT OF SAFETY REGULATIONS, CONSIDERATION OF AESTHETICS REDUCTION OF OPERATING COSTS, AND ADOPTION OF MODERNIZED OPERATIONAL PHILOSOPHIES TO FOSTER IMPROVED RECREATIONAL USE. THOUGHTFUL MANAGEMENT OF DRAINAGE SYSTEMS IS AN IMPORTANT ENVIRONMENTAL CONSIDERATION IN INTENSIVELY CULTIVATED AREAS TO IMPROVE AESTHETICS AND REDUCE POLLUTION, HEALTH AND SAFETY HAZARDS. RESPONSIBILITY FOR MANAGEMENT'S RELATIONSHIPS WITH WATER USERS IS SHARED BY THE INDUSTRY, THE PUBLIC, AND ALL LEVELS OF GOVERNMENT.

GREAT PROGRESS WAS MADE BY THE BUREAU BY EMPLOYING A WIDE VARIETY OF PROFESSIONALS TO STUDY NATURAL RESOURCES. WHEN IT CAME TIME TO IMPLEMENT NEPA, A SOUND FOUNDATION HAD BEEN PREPARED FOR ADVANCING INTENSE TREATMENT IN ALL PHASES OF ENVIRONMENTAL PROBLEMS. IN THE AREA OF IMPLEMENTATION, COMPARISONS OF ENVIRONMENTAL IMPACT STATEMENTS PREPARED BY THE BUREAU IN 1970-71 WITH THOSE PREPARED IN 1972-73 CLEARLY SHOWS THAT THE EXTRA EFFORT PUT FORTH BY THE BUREAU RESULTED IN A QUALITY PRODUCT. THE BUREAU HAS ALSO PIONEERED IN THE FIELD OF ENVIRONMENTAL EVALUATION SYSTEM ANALYSIS. IT HAS STAFFED AN ENVIRONMENTAL SPECIALIST IN EACH OF ITS REGIONAL OFFICES AS WELL AS TWO KEY MEN AT THE ENGINEERING AND RESEARCH CENTER, DENVER, TO HEAD UP THE ENVIRONMENTAL PROGRAM. A SOLID EXAMPLE OF THE BUREAU'S STRENGTH, IS ITS 'HANDLE' ON ENVIRONMENTAL POLICY WHICH ESTABLISHED THE NEW REQUIREMENT FOR MANDATORY PUBLIC HEARINGS ON FUTURE ENVIRONMENTAL STATEMENTS. AS A RESULT OF DEVELOPING NEW ATTITUDES, THE BUREAU HAS MADE SIGNIFICANT ADJUSTMENTS IN ITS FUNDING, STAFFING, AND PLANNING TO CARRY OUT THE ENVIRONMENTAL PROGRAM. MANAGEMENT HAS MADE SIGNIFICANT EFFORTS TO ACQUAINT THE BUREAU'S STAFF WITH ENVIRONMENTAL CONSIDERATIONS AND THE DEVELOPMENT OF POSITIVE ATTITUDES TOWARD ENVIRONMENTAL PROBLEMS.

NEW SPECIFICATION PROVISIONS DEALING WITH RESERVOIR AND RIGHT-OF-WAY CLEARING HAVE ALSO BEEN EFFECTIVE IN REDUCING PHYSICAL AND VISUAL IMPACT OF CONSTRUCTION ACTIVITIES. DESIGNERS OF STRUCTURES MUST NOT ONLY PROVIDE FOR OPERATING FUNCTION, BUT FOR AESTHETICS, ACCOMMODATIONS, FISH AND WILDLIFE MANAGEMENT, AND PRESERVATION OF THE NATURAL ENVIRONMENT AND WATER QUALITY. PROVIDING FOR FISH AND WILDLIFE IN ANY WATER DEVELOPMENT PROJECT IS ESSENTIAL. FISH PROPAGATION IS ASSURED AND ENHANCED BY MAINTAINING SUITABLE WATER QUALITY WHENEVER POSSIBLE AND BY PROVIDING FACILITIES FOR MIGRATING FISH SPECIES. CONCERN OVER ENVIRONMENTAL PROTECTION AND ENHANCEMENT IS A PRIMARY FACTOR IN ENVIRONMENTAL RECLAMATION. CONSIDERATION FOR PLEASANT SURROUNDINGS, AND FOR PERPETUATION OF ECOSYSTEMS HAS RISEN SHARPLY ON THE SCALE OF VALUES BY WHICH WE EVALUATE HUMAN EXISTENCE. THE BUREAU OF RECLAMATION HAS ACTED POSITIVELY TO INCLUDE GREATER CONSIDERATION OF THESE FACTORS IN ALL DESIGN AND CONSTRUCTION OF ITS PROJECTS. MANY ASPECTS OF DESIGN AND CONSTRUCTION ARE AIMED AT PROVIDING WATER RESOURCE PROJECTS WHICH ARE SATISFACTORY IN BOTH FUNCTION AND ENVIRONMENTAL ACCEPTABILITY.

THE MANURE STILL CONTAINED ABOUT 20 TO 25 PERCENT ESTIMATED DIGESTIBLE DRY MATTER. THE MINERAL CONTENT OF THE MANURE WAS HIGHER THAN THE RATION. INCREASING THE DRYING TEMPERATURE FROM 100 TO 200F, RESULTED IN AN INCREASE IN FIBER, LIGNIN AND SILICA AND A REDUCTION IN DIGESTIBILITY. THERE WERE LITTLE DIFFERENCES IN CHEMICAL COMPOSITION OR DIGESTIBILITY OF MANURE DRIED AT 14 PERCENT VERSUS 8 PERCENT, BUT 1 PERCENT INCREASED SILICA, FIBER AND LIGNIN.

IN MOST INSTANCES, PARTICULARLY FOR STRUCTURES IMPOUNDING CONSIDERABLE STORAGE, THE INFLOW DESIGN FLOOD IS THE MAXIMUM PROBABLE FOOD, WHICH IS DEFINED AS THE LARGEST FLOOD THAT CAN REASONABLY BE EXPECTED TO OCCUR ON A GIVEN STREAM AT A SELECTED POINT. DETERMINATION OF TBLE FLOOD IS BASED ON RATIONAL CONSIDERATION OF THE CHANCES OF SIMULTANEOUS OCCURRENCE OF THE MAXIMUM OF THE SEVERAL ELEMENTS OR CONDITIONS WHICH CONTRIBUTE TO THE FLOOD. A MAJOR CONSIDERATION IS THE DETERMINATION OF THE RUNOFF THAT WOULD RESULT FROM AN OCCURRENCE OF A PROBABLE MAXIMUM STORM BASED ON METEROLOGICAL FACTORS. THIS HYDROMETEOROLOGICAL APPROACH IS NECESSARY BECAUSE STREAMFLOW RECORDS ARE OF SUCH RELATIVELY SHORT DURATION IN THE UNITED STATES THAT STATISTICAL ANALYSES THEREOF DO NOT PROVIDE RELIABLE BASES FOR ESTIMATES OF MAXIMUM PROBABLE FLOODFLOWS. METHODS OF DETERMINING THE MAGNITUDE AND FREQUENCY OF FLOODS AS INDICATED BY STATISTICAL ANALYSES OF STREAMFLOW RECORDS ARE PRIMARILY FOR USE IN CONNECTION WITH ESTIMATING DIVERSION REQUIREMENTS DURING CONSTRUCTION, ESTABLISHING FREQUENCY OF USE OF EMERGENCY SPILLWAYS USED IN CONJUNCTION WITH OUTLETS OR SMALL SPILLWAYS, DETERMINING PEAK DISCHARGE ESTIMATES FOR DIVERSION DAMS, OR PROVIDING OTHER INFORMATION USEFUL TO THE DESIGNERS.

PRIOR TO IMPLEMENTING RESOURCE UTILIZATION AND EXTRACTION ACTIVITIES, THE LAND MANAGER MUST BE AWARE OF THE EVENTUAL IMPLICATIONS OF ANY PROPOSED DECISION AND ITS IMPACT ON FUTURE PRODUCTIVITY AND USE OF EACH FINITE COMMODITY. EVEN A MINOR SURFACE DISTURBANCE MAY ALTER THE THERMAL BALANCE SUFFICIENTLY TO INDUCE PERMAFROST THAWING, WHICH MAY RESULT IN SUBSIDENCE OR SOIL EROSION OR BOTH, AND AFFECT SUCH FEATURES AS SURFACE RELIEF, ACCESS, SILTATION, AND WILDLIFE HABITAT. CHANGES IN SURFACE RELIEF, SUCH AS DEPRESSIONS FROM SUBSIDENCE OR GULLIES FROM EROSION BY WATERS OF MELTING SOIL ICE INTERFERE WITH SUBSEQUENT CONSTRUCTION OR LAND TRAVEL. ERODING SOIL SOLIDS BECOME DEPOSITED AT SOME LOWER POINTS IN THE WATERSHED OR DRAINAGEWAY, WHICH FURTHER LIMIT UTILIZATION OF THE LAND.

ANALYSIS OF OPEN CHANNEL FLOW IN OUTLET WORKS, EITHER IN AN OPEN WATERWAY OR IN A PART FULL CONDUIT, IS BASED ON THE PRINCIPLE OF STEADY NONUNIFORM FLOW CONFORMING TO THE LAW OF CONSERVATION OF ENERGY.

ORDINARILY, THE EXCESS IS DRAWN FROM THE TOP OF THE POOL CREATED BY THE DAM AND CONVEYED THROUGH AN ARTIFICIAL WATERWAY BACK TO THE RIVER OR TO SOME NATURAL DRAINAGE CHANNEL. AMPLE CAPACITY IS OF PARAMOUNT IMPORTANCE FOR EARTHFILL AND ROCKFILL DAMS, WHICH ARE LIKELY TO BE DESTROYED IF OVERTOPPED, WHEREAS CONCRETE DAMS MAY BE ABLE TO WITHSTAND MODERATE OVERTOPPING. IN ADDITION TO PROVIDING SUFFICIENT CAPACITY, THE SPILLWAY MUST BE HYDRAULICALLY AND STRUCTURALLY ADEQUATE AND MUST BE LOCATED SO THAT SPILLWAY DISCHARGES WILL NOT ERODE OR UNDERMINE THE DOWNSTREAM TOE OF THE DAM. THE SPILLWAY'S BOUNDING SURFACES MUST BE EROSION RESISTANT TO WITHSTAND THE HIGH SCOURING VELOCITIES CREATED BY THE DROP FROM THE RESERVOIR SURFACE TO TAILWATER, AND USUALLY SOME DEVICE WILL BE REQUIRED FOR DISSIPATION OF ENERGY AT THE BOTTOM OF THE DROP.

BESIDES PROVIDING UPWARD OF 2.5 MILLION ACRE-FEET OF HIGH QUALITY WATER ANNUALLY, THE USE OF GEOTHERMAL RESOURCES COULD ADD UP TO 10 MILLION KILOWATTS OF ELECTRICAL ENERGY TO THE PACIFIC-SOUTHWEST POWER SYSTEMS. PRELIMINARY INVESTIGATIONS SHOW THAT SEVERAL BILLION ACRE-FEET OF HOT BRINE EXIST IN THE IMPERIAL VALLEY GEOTHERMAL FIELD AND WHEN TAPPED BY A DEEP WELL WILL TURN INTO A MIXTURE OF STEAM AND HOT BRINE WATER. THE STEAM CAN BE USED TO POWER TURBINES AS WELL AS BE CONVERTED INTO WATER. THE HOT BRINE CAN BE DEMINERALIZED FOR THE MINERAL BY-PRODUCTS AS WELL AS PROVIDING FRESH WATER, OR COULD BE REINJECTED INTO THE GEOTHERMAL REGION. THE BUREAU OF RECLAMATION IS DEVELOPING THIS PROGRAM IN THREE STAGES: (1) RESEARCH AND DEVELOPMENT, (2) LIMITED-SCALE DEMONSTRATION, AND (3) LARGE-SCALE PRODUCTION.

MAXIMUM ARSENIC CONCENTRATIONS FOUND IN THE FIRST WATER RELEASED THROUGH DEWATERED LATERALS WERE 0.54, 0.12, AND 0.29 PPM, DROPPING BELOW THE MANDATORY US PUBLIC HEALTH SERVICE DRINKING WATER STANDARDS FOR ARSENIC WITHIN 10 MIN. MAXIMUM ARSENIC CONCENTRATIONS IN FULL CANAL SYSTEMS FOLLOWING MSMA HERBICIDE APPLICATION TO DITCHBANKS WERE 0.16, 0.17, AND 0.86 PPM, BUT DROPPED RAPIDLY AFTER A PERIOD OF TIME. TEST RESULTS SHOW THAT LOW LEVELS OF ARSENIC OCCUR IN IRRIGATION WATER FOR SHORT PERIODS OF TIME FOLLOWING DITCHBANK APPLICATIONS OF MSMA. THEORETICAL CALCULATIONS INDICATE THAT FROM 0.002 TO 0.04 LB OF ARSENIC PER ACRE PER TREATMENT COULD REACH THE FARMLAND DURING A 24-HR PERIOD USING 6 IN. OF IRRIGATION WATER.

AN EXAMPLE USING THIS PROCEDURE IS GIVEN FOR THE SAN JUAN RIVER AND INDICATES 58% OF THE ANNUAL SEDIMENT YIELD OCCURS DURING THE THUNDERSTORM PERIOD, ALTHOUGH THE RUNOFF DURING THAT PERIOD IS ONLY 36% OF THE AVERAGE ANNUAL VALUE. IN ANOTHER SITUATION WHERE ALAMO DAM WAS CLOSED UPSTREAM OF LAKE HAVASU, SEDIMENT YIELD RATE CURVES WERE USED TO CALCULATE THE NEW SEDIMENT YIELD. THESE CURVES ARE DEVELOPED BY PLOTTING THE SEDIMENT YIELD PER UNIT AREA PER YEAR AGAINST THE DRAINAGE AREA FOR WATERSHEDS WITH SIMILAR CLIMATIC, TOPOGRAPHIC, AND GEOLOGIC CONDITIONS.

TO AVOID STRUCTURAL PROBLEMS CAUSED BY DIFFERENTIAL SETTLEMENT FROM FUTURE IRRIGATION ALONG THE WATER DISTRIBUTION SYSTEM, COLLAPSING SOILS ARE WETTED BEFORE CONSTRUCTION TO PRODUCE A MORE STABLE FOUNDATION CONDITION. TO EVALUATE METHODS OF WETTING COLLAPSING SOILS, TEST SECTIONS WERE INSTALLED USING FLOODING AND SPRINKLING METHODS WITH AND WITHOUT VERTICAL INFILTRATION WELLS. RESULTS INDICATE: (1) SURFACE FLOODING OR SPRINKLING IN CONJUNCTION WITH 40-FT DEEP WELLS ON 40-FT CENTERS COLLAPSED A 50-FT DEPTH OF SOIL IN ONLY 30 DAYS; (2) SURFACE FLOODING OR SPRINKLING WITHOUT WELLS CONSERVES WATER, BUT TAKES 60 TO 90 DAYS TO REACH A 50-FT DEPTH, PROVIDING IMPERVIOUS LAYERS DO NOT PREVENT VERTICAL INFILTRATION; AND (3) SURFACE FLOODING WITH 100-FT DEEP WELLS ON 100-FT CENTERS REQUIRED 4 MONTHS WETTING TIME TO REACH A DEPTH OF 110 FT.

UNDER THE BUREAU OF RECLAMATION'S LEADERSHIP, A PROGRAM CALLED PROJECT SKYWATER HAS GROWN FROM A BUDGET OF $100,000 COVERING 3 CONTRACTS TO AN ANNUAL BUDGET OF $6,600,000 COVERING 49 CONTRACTS. FROM THE BEGINNING, ATTENTION WAS FOCUSED ON THE GREAT PLAINS REGION. A TABLE LISTS THE CONTRACTS INVOLVED IN THE GREAT PLAINS REGION AND THE COMPLETION DATES. ABOUT 90% OF PROJECT SKYWATER FUNDS ARE SPENT IN THE FIELD BY THE PARTICIPATING CONTRACTORS, MANY OF WHOM ARE IN PRIVATE SECTOR. A BUREAU STAFF OF 25, INCLUDING PEOPLE EXPERIENCED IN WEATHER MODIFICATION, METEOROLOGY, OTHER SCIENCES, ENGINEERING, AND ADMINISTRATION, IS CENTRALLY LOCATED IN DENVER TO PLAN AND DIRECT THE PROGRAM. HYGROSCOPIC SEEDING IS A RELATIVELY NEW TYPE OF SEEDING BEING DEVELOPED WHICH PROMISES TO BE VERY EFFECTIVE IN MODIFYING CLOUDS UNAFFECTED BY SILVER IODIDE. IN HYGROSCOPIC SEEDING, SUCH MATERIALS AS COMMON SALT AND A MIXTURE OF AMMONIUM NITRATE/UREA MAY BE USED. THEY HAVE THE UNIQUE ABILITY TO ABSORB WATER VAPOR FROM THE SURROUNDING AIR. IT IS THE BUREAU OF RECLAMATION'S CONTENTION THAT SCIENTIFICALLY SOUND LOCAL, STATE, AND FEDERAL COOPERATIVE PROGRAMS CAN BE IMPLEMENTED TO PROVIDE BOTH THE NECESSARY LEARNING AND THE IMMEDIATE BENEFITS OF ADDITIONAL WATER.

CONSEQUENTLY, ANY UNSTEADINESS IN THE FLOW MAY BE AMPLIFIED, DEPENDING UPON THE CHARACTERISTICS OF THE SYSTEM. THE STUDY WAS PERFORMED TO ESTABLISH PARAMETERS FOR USE IN DESIGN OF LOW-PRESSURE PIPE SYSTEMS BY PREDICTING AMPLITUDE AND FREQUENCY OF UNSTEADY FLOW OCCURRING AT FLOW RATES BELOW THE DESIGN VALUE. A SYSTEM MUST BE DESIGNED SO THAT SMALL DISTURBANCES IN ONE REACH ARE NOT AMPLIFIED IN A SUCCEEDING REACH; WHEN THE NATURAL PERIOD OF A DOWNSTREAM SECTION EXCEEDS THE PERIOD OF THE INCOMING DISTURBANCE BY A FACTOR OF 1.43, THEN INCOMING SURGES ARE NOT LIKELY TO OCCUR. AN ANALYTICAL STUDY OF SURGE DYNAMICS WAS CONDUCTED. TABULATIONS DISPLAY THE RESULTS, AND NUMEROUS CURVES ARE GIVEN TO SHOW DIMENSIONLESS DISCHARGE VARIATIONS VERSUS A FUNCTION OF DIMENSIONLESS TIME AND DIMENSIONLESS DISCHARGE CUTBACK RATIO. OTHERS SHOW SURGE AMPLITUDES AS A FUNCTION OF A RESISTANCE COEFFICIENT. AN APPENDIX GIVES COMPUTER PROGRAMS FOR DIMENSIONLESS AQUEDUCT PARAMETERS AND SURGE CHARACTERISTICS.

IRRIGATION MANAGEMENT HAS BEEN MADE POSSIBLE BY ADAPTATION OF A COMPUTER PROGRAM TO THE JENSEN-HAISE METHOD OF COMPUTING CROP CONSUMPTIVE USE. A DAILY SOIL MOISTURE LEVEL BALANCE IS AVAILABLE BY INSERTING CLIMATIC PARAMETERS FOR A COMPUTER PRINTOUT AT A SPECIFIC TIME. THESE PRINTOUTS ARE PRESENTED TO IRRIGATORS WHO CAN BE SHOWN WHEN THE NEXT IRRIGATION APPLICATION WILL BE REQUIRED FOR A SPECIFIC FIELD. THIS WILL IMPROVE IRRIGATION EFFICIENCIES BECAUSE THE WATER WILL BE APPLIED WHEN THE SOIL MOISTURE LEVEL IS DEFICIENT. DATA PREVIOUSLY COLLECTED INDICATED THAT IRRIGATORS WERE UNAWARE OF SOIL MOISTURE LEVELS WHEN APPLYING WATER. IRRIGATION MANAGEMENT SERVICES BEING CONDUCTED BY BUREAU OF RECLAMATION PERSONNEL IN KANSAS AND WYOMING ARE PRESENTED. DATA FOR THE IRRIGATION MANAGEMENT HAVE BEEN ANALYZED SHOWING RESULTS DURING 1971. THE FUTURE OF IRRIGATION MANAGEMENT IS EXPLOITED AND INCORPORATED WITH OPERATION OF IRRIGATION SYSTEMS.

IN EACH INSTANCE THE DAMAGE WAS READILY TRACEABLE TO MISALIGNMENT OR IRREGULARITY IN THE FLOW SURFACE. A SMALL AMOUNT OF AIR SUPPLIED TO THE SIDES AND BOTTOM OF A JET WILL PREVENT CAVITATION DAMAGE DOWNSTREAM FROM REGULATING GATES. MODEL STUDIES WERE CONDUCTED TO DEVELOP A METHOD OF AERATING THE JET. THESE STUDIES RESULTED IN THE DEVELOPMENT OF A 12-INCH-SQUARE AERATION GROOVE IN THE SIDEWALLS OF THE EXISTING CONDUIT IMMEDIATELY DOWNSTREAM FROM THE GATE FRAME. TO CAUSE THE FLOW TO CLEAR THE GROOVES, A 1-INCH DEFLECTOR WILL BE PLACED IN EACH SIDEWALL IMMEDIATELY UPSTREAM FROM THE GROOVE. SEVERAL GATE CONFIGURATIONS WERE TESTED TO DEVELOP GENERAL GUIDELINES FOR AERATING THE FLOW FROM OUTLET GATES. RATHER THAN USING AERATION GROOVES WHICH WERE USED ON EXISTING STRUCTURES AND WHICH MUST BE CAREFULLY DESIGNED TO PREVENT THEM FROM FILLING WITH WATER, THE BUREAU OF RECLAMATION PLANS TO PROVIDE OUTWARD OFFSETS ON THE SIDEWALLS AND INVERT OF FUTURE STRUCTURES. IN GENERAL, AN OFFSET ON THE INVERT EQUAL TO ONE-SIXTH THE WIDTH OF THE GATE AND OFFSETS ON THE SIDEWALLS EQUAL TO ONE-TWELFTH OF THE GATE WIDTH ARE ADEQUATE TO AERATE THE JET AND MINIMIZE FINS OF WATER IN THE DOWNSTREAM FLOW PASSAGE.

TOLERANCES FOR CONCRETE SURFACES, EMBEDDED MATERIALS, AND MECHANICAL EQUIPMENT WERE STUDIED TO DETERMINE THEIR INFLUENCE ON REQUIRED ACCURACY OF CONTROLS. TO OBTAIN A HIGHER ACCURACY THAN MAY BE NEEDED IS MUCH MORE ECONOMICAL THAN TO LOWER THE ACCURACY AND BE PLAGUED BY RESULTS THAT DO NOT MEET SPECIFIED TOLERANCES AND MAY REQUIRE COSTLY REMEDIAL WORK.

BECAUSE OF THE VARIETY OF SOIL CONDITIONS FOUND ALONG A TRANSMISSION LINE AND THE NUMBER OF FOOTINGS INVOLVED, ECONOMICAL BUT ADEQUATE FOOTING DESIGNS ARE IMPORTANT. CONCRETE BELLED AUGER FOOTINGS BEST SATISFIED DESIGN REQUIREMENTS. THESE FOOTINGS ARE CONSTRUCTED BY AUGERING A HOLE OF A CERTAIN DEPTH INTO THE FOUNDATION MATERIAL, ENLARGING THE BOTTOM OF THE HOLE TO FORM A BELL, AND FILLING THE HOLE WITH CONCRETE. DURING 1947, FULL-SCALE TESTS OF BELLED AUGER TOWER FOOTINGS WERE PERFORMED BY THE BUREAU OF RECLAMATION AT SEVERAL LOCATIONS IN CALIFORNIA. NO ADDITIONAL TESTS WERE MADE UNTIL 1960, WHEN THE FORT PECK-DAWSON COUNTY 230-KV LINE WAS BUILT IN AN AREA OF SILTY SAND FOUNDATION MATERIAL. THE LAST FULL-SCALE FIELD TESTS WERE MADE DURING JUNE 1967, ON THE MEAD-LIBERTY 345-KV LINE. THE FOOTING TESTS, ALL OF WHICH PROVED THE ADEQUACY OF DESIGN, ARE DISCUSSED.

EACH TEST SECTION, COMPOSED OF 12% CEMENT MIXED WITH SILTY SAND, WAS ABOUT 1,200 FT SQ AND 2.54 FT THICK. THE SEEPAGE WATER FLOWED INTO A LAYER OF PERVIOUS SAND AND THEN DRAINED INTO A COLLECTION TANK. CALCULATED SEEPAGE RATES VARIED FROM AS HIGH AS 0.15 FT/DAY INITIALLY, TO AN AVERAGE OF 0.005 FT/DAY IN WARM MONTHS, AND ABOUT 0.04 FT/DAY IN COLDER MONTHS. THESE RATES WERE SOMEWHAT GREATER THAN THE RATE FROM A STANDARD LABORATORY TEST, INDICATING THAT CONSIDERABLE SEEPAGE FLOWED THROUGH SHRINKAGE CRACKS AND CONSTRUCTION CONTACT PLANES BETWEEN LAYERS.

BASIC DATA OBTAINED DURING CONSTRUCTION OF THE DAM WERE ANALYZED TO COMPARE THE 2 METHODS. DATA INCLUDED PORE WATER PRESSURE READINGS, INTERNAL COMPRESSION OF 10-FT LIFTS, CONSTRUCTION REPORTS, AND RESULTS OF CONSTRUCTION CONTROL TESTING. RESULTS INDICATE THAT GIBSON'S METHOD WOULD NOT HAVE SUCCESSFULLY PREDICTED TRINITY DAM PORE PRESSURES, BUT IN EMBANKMENTS WHERE THE SOIL IS COMPACTED AT OR SLIGHTLY WETTER THAN OPTIMUM WATER CONTENT, THE METHOD SHOULD YIELD BETTER RESULTS. HILF'S METHOD PREDICTED PORE PRESSURES CLOSER TO MEASURED VALUES; ALLOWANCE FOR NEGATIVE PORE PRESSURES WOULD HAVE IMPROVED THE PREDICTION.

AS THE YEARS PASSED, THE BUREAU APPLIED THE METHOD TO MANY ANALYTICAL PROBLEMS INCLUDING IN SITU ROCK, CONCRETE DAMS, EARTH AND ROCKFILL DAM FOUNDATIONS, STRUCTURES AND FLOW NETS. RESULTS OF GRAND COULEE FOREBAY DAM FOUNDATION ANALYSES WERE USEFUL IN DETERMINING THE AMOUNT OF CONCRETE TREATMENT NECESSARY IN A FAULT ZONE UNDER THE DAM, FOR CHECKING THE ADEQUACY OF THE PROPOSED FOUNDATION DRAINAGE SYSTEM, AND FOR DETERMINING THE STABILITY OF THE DAM FOUNDATION ALONG A MAJOR JOINT SYSTEM. STATIC ANALYSES OF STRESSES AND DEFORMATIONS IN EARTH AND ROCKFILL DAMS ARE MADE USING A PROGRAM THAT MODELS THE SEQUENTIAL CONSTRUCTION OF EMBANKMENTS AND THE NONLINEAR, STRESS-DEPENDENT BEHAVIOR OF THE MATERIALS. AS APPLICATIONS TO LARGER PROBLEMS GREW, METHODS TO SIMPLIFY INPUT OF DATA IMPROVED WITH AUTOMATIC GENERATION OF THE FINITE ELEMENT MESH AND MUCH OF THE INPUT DATA. IMPROVING THE MATERIALS ANALYSIS TO ALLOW TRULY REPRESENTATIVE VALUES AND COMPARING ACTUAL STRUCTURAL BEHAVIOR WITH PREDICTED BEHAVIOR ARE AREAS IN WHICH MORE WORK SHOULD BE DONE.

THE FLUME HAS SIDE SLOPE ANGLES OF 45 DEG. THE ANGLES OF CONVERGENCE OF THE INLET TRANSITION AND DIVERGENCE OF THE OUTLET TRANSITION WERE 5 DEG. THE INLET TRANSITION THROAT AND OUTLET TRANSITION WERE 3 FT LONG. THE THROAT BOTTOM WIDTH WAS 4 IN. THE MEASURING STATION WAS ONE-HALF FT UPSTREAM FROM THE START OF THE CONVERGENCE. THE FLUME WAS CALIBRATED FOR A PAINTED WOOD SURFACE AND A SAND-COATED SURFACE. THE DISCHARGE RANGE WAS 0.5 TO 5.0 CFS. THE MEASURING HEAD FOR THE SAND ROUGHENED FLUME WAS 2% HIGHER AT 0.5 CFS AND 1% HIGHER AT 5.0 CFS THAN FOR THE PAINTED WOOD FLUME. ERRORS IN DISCHARGE FROM 2-1/2 TO 4-1/2% OCCUR WHEN FRICTION IS NEGLECTED IN COMPUTING THE DISCHARGE FROM EQUATIONS DEVELOPED FOR THE PAINTED WOOD FLUME. ENERGY LOSSES FOR THE FLAT-BOTTOM TRAPEZOIDAL VENTURI FLUME ARE FROM 30 TO 50% OF THE LOSSES FOR THE 1-FT PARSHALL FLUME WHICH HAS ABOUT THE SAME DISCHARGE RANGE. BACKWATER COMPUTATIONS CAN BE USED TO CALCULATE MEASURING HEAD ELEVATION. HOWEVER, PRIOR KNOWLEDGE OF FRICTION AND EDDY LOSS FACTORS IS REQUIRED.

USUALLY, A SERIES OF ESTABLISHED MIXES IS USED THROUGHOUT THE JOB; HOWEVER, CHANGING AGGREGATE MOISTURES AND GRADATIONS REQUIRE FREQUENT ADJUSTMENT OF SCALE WEIGHTS TO ACHIEVE CONCRETE UNIFORMITY. TEST BATCHES ARE TAKEN, YIELD QUANTITIES ARE CALCULATED, AND DETAILED RECORDS KEPT. SEVERAL HOURS EACH DAY ARE SPENT PERFORMING AND CHECKING THESE ITERATIVE CALCULATIONS. BY USING A TELETYPE LOCATED AT THE MIXING PLANT OR IN THE PROJECT LABORATORY, A LARGE COMPUTER CAN BE INSTRUCTED TO MAKE THESE ROUTINE CALCULATIONS. MORE EXACT CONTROL IS ACHIEVED, AND MOISTURE, GRADATION, AND SCALE WEIGHTS CAN BE CALCULATED IN A FRACTION OF THE TIME PRESENTLY REQUIRED. THE AVERAGE BATCH PLANT TECHNICIAN CAN BE TAUGHT TO USE THE TECHNIQUE IN A FEW HOURS. RECORDS OF SCALE WEIGHTS AND YIELD QUANTITIES CAN BE STORED IN THE COMPUTER AND RECALLED AT ANY TIME. THE PRACTICALITY OF USING A COMPUTER FOR CONCRETE CONTROL HAS BEEN DEMONSTRATED AT A BUREAU OF RECLAMATION PROJECT.

THREE MATERIALS UNDER INVESTIGATION ARE: (1) POLYMER-IMPREGNATED CONCRETE (PIC--PRECAST PORTLAND CEMENT CONCRETE IMPREGNATED WITH MONOMER WHICH IS SUBSEQUENTLY POLYMERIZED IN SITU); (2) POLYMER-CEMENT CONCRETE (PCC--A PREMIXED MATERIAL, IN WHICH MONOMER OR POLYMER IS ADDED DURING THE MIXING OF PORTLAND CEMENT CONCRETE); AND (3) POLYMER-CONCRETE (PC--A COMPOSITE MATERIAL FORMED BY POLYMERIZING A MONOMER AND AGGREGATE MIXTURE). INVESTIGATIONS TO DATE SHOW THE MOST SUCCESS WITH PIC, SOME PROMISE FOR PC, AND THE LEAST SUCCESS WITH PCC. SEVEN MONOMER SYSTEMS FOR PIC ARE CURRENTLY UNDER TEST FOR NORMAL TEMPERATURE APPLICATIONS AND SEVERAL ARE BEING EVALUATED FOR HIGH TEMPERATURE APPLICATIONS. ALL MONOMER PIC SYSTEMS SHOW REMARKABLE IMPROVEMENTS IN DURABILITY AND STRUCTURAL PROPERTIES COMPARED WITH CONVENTIONAL CONCRETE. COMPRESSIVE STRENGTHS AS HIGH AS 27,200 PSI HAVE BEEN MEASURED. PROCESS TECHNOLOGY IMPROVEMENTS INCLUDE USE OF STEAM-CURED CONCRETE, POLYMERIZATION UNDER WATER, AND ENCAPSULATION METHODS TO REDUCE MONOMER LOSSES. PIC IS BEING STUDIED FOR USE IN DESALTING PLANTS, DRAINTILE, CULVERT AND SEWER PIPE, BRIDGE DECKS, MARINE APPLICATIONS, AND PRECAST TUNNEL LINERS AND SUPPORTS.

ELBERT PUMPED-STORAGE POWERPLANT IN COLO. THE MAIN PURPOSE FOR THE STUDIES WAS TO DEVELOP A DESIGN TO PROVIDE A UNIFORM VELOCITY DISTRIBUTION AT THE TRASHRACKS DURING THE PUMPED CYCLE. UNIFORM VELOCITY DISTRIBUTION WOULD MINIMIZE THE POSSIBILITY OF FORMING STRONG VORTEX SHEDDING AND REDUCE THE FORCES CAUSING TRASHRACK FATIGUE FAILURE. FLOW CONDITIONS FOR THE GENERATING CYCLE WERE EVALUATED TO ENSURE A UNIFORM VELOCITY DISTRIBUTION FREE OF AIR ENTRAINING SURFACE VORTICES. HEAD LOSS MEASUREMENTS WERE MADE FOR THE INLET-OUTLET STRUCTURE AND A PORTION OF THE PENSTOCKS. A HORIZONTAL DEFLECTOR WITH FLIP BLOCKS WAS DEVELOPED TO IMPROVE THE VERTICAL VELOCITY DISTRIBUTION AT THE TRASHRACK POSITION. A FLAT UPWARD SLOPING FLOOR WAS DEVELOPED TO REPLACE THE ORIGINAL CONCAVE FLOOR IN THE STRUCTURE. BOTH A RAFT-TYPE STRUCTURE AND A LATTICE-LIKE WALL STRUCTURE WERE DEVELOPED TO SUPPRESS GENERATION OF SURFACE VORTICES. NEITHER STRUCTURE ELIMINATED THE VORTICES, BUT DID ELIMINATE AIR INTAKE INTO THE PENSTOCKS. (USBR) JF - BUREAU OF RECLAMATION REPORT REC-ERC-72-5, JAN 1972. 16 P, 16 FIG.

TO AVOID FUTURE PROBLEMS, AN AERATION SLOT WAS ADDED AND DAMAGED AREAS WERE REPAIRED. METHODS AND MATERIALS USED TO REPAIR THE DAMAGED AREAS DEPENDED ON REPAIR DEPTHS: EPOXY BONDED EPOXY MORTAR FOR DEPTHS LESS THAN 1-1/2 TO 2 IN., EPOXY BONDED CONCRETE FOR DEPTHS FROM 2 TO 6 IN., AND BONDED CONCRETE FOR DEPTHS OVER 6 IN. EPOXY BONDED EPOXY MORTAR IS DIFFICULT TO APPLY. BEFORE PLACING THE EPOXY MORTAR, THE CONCRETE SURFACE MUST BE DRIED AND SANDBLASTED. WATER SEEPAGE THROUGH HAIRLINE CRACKS HAMPERED THE DRYING PROCEDURE UNTIL A CHEMICAL GROUT SUCCESSFULLY REDUCED THE FLOW. AFTER HEATING THE PREPARED CONCRETE SURFACE TO BETWEEN 60 AND 70 DEG F, THE 2 COMPONENTS OF THE EPOXY BOND COAT WERE MIXED AND APPLIED. THE EPOXY MORTAR WAS A MIXTURE OF EPOXY RESIN AND CLEAN, DRY, WELL-GRADED SAND. DURING REPAIRS, THE EPOXY MORTAR PRESENTED SOME PROBLEMS IN MIX DESIGN, FINISHING, CURING, PLACING, AND PAINTING.

DURING 1940, RHEINGANS SUMMARIZED EXPERIENCES AND PRESENTED AN EQUATION FOR ESTIMATING THE EXPECTED FREQUENCY OF SURGING. INVESTIGATORS NOW ACCEPT THE FACT THAT THE DRAFT TUBE SURGE IS A HYDRODYNAMIC INSTABILITY OCCURRING IN THE DRAFT TUBE AS A RESULT OF ROTATION REMAINING IN THE FLUID AS IT LEAVES THE TURBINE RUNNER AND ENTERS THE DRAFT TUBE THROAT. EXPERIMENTAL ANALYSIS AND LABORATORY PROCEDURES ARE DISCUSSED. DRAFT TUBE SHAPES WERE STUDIED AND SURGE DATA OBTAINED FOR OVER 50 DISTINCT DRAFT TUBE SHAPES. CONCLUSIONS ARE: (1) DEGREE OF DIVERGENCE OF A DRAFT TUBE IS THE MOST SIGNIFICANT GEOMETRIC FEATURE AFFECTING SURGING CHARACTERISTICS; (2) SURGING CAN BE MINIMIZED BY USING AN EQUIVALENT EXPANSION ANGLE OF ABOUT 15 DEG THROUGH THE ENTIRE LENGTH OF THE DRAFT TUBE; AND (3) RESONANCE WITH KNOWN NATURAL FREQUENCIES OF OTHER FEATURES OF THE POWERPLANT CAN BE CHECKED USING RESULTS PRESENTED. RESONANCE CAN BE AVOIDED BY SELECTING PROPER GEOMETRIC COMPONENTS IN DRAFT TUBE DESIGN.

THE LITERATURE SURVEY CONSISTS OF AN ANNOTATED BIBLIOGRAPHY OF 68 ARTICLES PUBLISHED BETWEEN 1910 AND 1970. THE REVIEW IS RESTRICTED TO 3 MAJOR AREAS: EXPERIMENTS WITH ELEMENTARY MODELS, EXPERIMENTS WITH MODEL AND PROTOTYPE TURBINES, AND FIELD EXPEDIENTS TO REDUCE SURGING. VELOCITY DISTRIBUTIONS AND SURGE FREQUENCIES ARE GIVEN SPECIAL ATTENTION IN THE FIRST 2 AREAS. PRESENT KNOWLEDGE IS SUFFICIENT FOR PREDICTING THE ORDER OF MAGNITUDE OF DRAFT TUBE SURGE FREQUENCIES AND RELATIVE SURGE AMPLITUDES. ADDITIONAL STUDIES ARE NEEDED TO REFINE AND EXTEND THE SCOPE OF PREDICTION METHODS TO INCLUDE PUMPS AND PUMP-TURBINES. MODEL TESTING AT FULL PROTOTYPE HEADS IS NOT REQUIRED TO INVESTIGATE DRAFT TUBE SURGING. (USBR) JF - BUREAU OF RECLAMATION REPORT REC-ERC-71-42, DEC 1971. 25 P, 7 FIG, 68 REF.

THE PROGRAM INCLUDED ROCK MOVEMENT MEASUREMENTS, CONCRETE LINING MEASUREMENTS, AND A LINING PER FORMANCE TEST. NO ROCK MOVEMENT PATTERN RELATING TO THE OVERBURDEN, ROCK TYPE, OR JOINTING COULD BE DETECTED. LARGE MOVEMENTS OCCURRED WHERE LOCAL FALLOUT WAS COMMON. AT DEPTHS OF 800 FT OR MORE, HORIZONTAL AND VERTICAL DIAMETERS CONVERGED; AT LESSER DEPTHS, AN ELLIPTICAL SHAPE DEVELOPED WITH THE VERTICAL DIAMETERS CONVERGING AND THE HORIZONTAL DIAMETERS DIVERGING. THE CONCRETE LINING INSTRUMENTATION SHOWED CONCRETE SHRINKAGE AWAY FROM THE ROCK AND DEFORMATION OF THE LINING INTO A SLIGHTLY ELLIPTICAL SHAPE. EXCEPT IN THE SHOTCRETED SECTION, THE JOINT METERS INDICATED THE ROCK WAS PLACING A LOAD ON THE LINING. STRAIN METERS MEASURED THE STRAIN INDUCED BY THE ROCK. FROM THE STRAINS, THE CONCRETE STRESSES COULD BE COMPUTED. RESULTS FROM THE SHOTCRETED SECTION SUGGEST THAT THE SHOTCRETE PROTECTED THE SHALE AND PREVENTED CHANGES IN THE STABILITY OF THE ROCK MASS. THE LINING PERFORMANCE TEST SHOWED THE EXPANSIVE CHARACTERISTICS OF THE SHALE AND THEIR EFFECT ON THE LINING. PRESSURES DEVELOPED IN THE SHALE WERE SUFFICIENTLY HIGH TO CAUSE CRACKING AND RELATIVELY LARGE MOVEMENTS IN THE CONCRETE LINING.

FURTHER FIELD OPERATION AND EXPERIENCE ARE NECESSARY TO FULLY EVALUATE MECHANICAL DESIGN OF THE NEW DEVICES. DURING LABORATORY TESTS, OPERATIONAL DIFFICULTIES SUCH AS LEAKAGE, FAILURE TO INTERNALLY RECOGNIZE CLOSURE INITIATION, AND SLOWNESS OF OR EVEN REFUSING TOCONTROL FLOW, WERE EXPERIENCED WITH BOTH VERSIONS OF THE DEVICE. THESE DIFFICULTIES WERE MOSTLY RELATED TO LOW LINE PRESSURE OR PRIOR PERIODS OF NO LINE PRESSURE. LABORATORY TESTS ALSO INDICATE THAT PUMP OPERATIONS CAN CAUSE TEMPORARY OVERDELIVERY. LOW HEAD CONDITIONS AND OVERDELIVERY IN RESPONSE TO PRESSURE INCREASE SHOULD BE CONSIDERED IN TERMS OF SPECIFIC PROJECT REQUIREMENTS DURING DESIGN.

THE DAMAGE WAS CAUSED BY CAVITATION INITIATED BY SURFACE IRREGULARITIES IN THE TUNNEL LINING. THE MAJOR DAMAGE WAS CONCENTRATED IN THE VERTICAL BEND AND IN THE TUNNEL JUST DOWNSTREAM FROM THE BEND. AN AERATION SLOT TO INTRODUCE AIR INTO THE FLOWING WATER WAS TO BE CONSTRUCTED CONCURRENTLY WITH TUNNEL REPAIRS. A LABORATORY MODEL OF THE TUNNEL WAS USED TO STUDY VARIOUS LOCATIONS AND CONFIGRUATIONS OF AERATION SLOTS. AS A RESULT OF THE MODEL STUDY, ONE AERATION SLOT WAS DESIGNED THAT WAS SUITABLE FOR ALL SPILLWAY DISCHARGES. THE OPTIMUM LOCATION FOR THE SLOT WAS DETERMINED TO BE JUST UPSTREAM FROM THE VERTICAL BEND. (USBR) JF - BUREAU OF RECLAMATION REPORT REC-ERC-71-47, DEC 1971. 11 P, 18 FIG.

THESE PROBLEMS CAN BE SOLVED BY RAPID COMPUTERIZED ADJUSTMENTS OF MIX PROPORTIONS DURING BATCHING AND MIXING. THE BATCH PLANT MUST HAVE A TELEPHONE AND A PORTABLE TIME-SHARING COMPUTER TERMINAL. A BATCH PLANT TECHNICIAN DOES NOT REQUIRE COMPUTER EXPERIENCE TO LEARN, IN ABOUT 2 HR, TO MAKE MIX ADJUSTMENTS USING THIS EQUIPMENT. ANOTHER RESULT OF THE SEARCH FOR IMPROVED CONCRETE IS THE DEVELOPMENT OF CONCRETE-POLYMER MATERIALS. CONCRETE IMPREGNATED WITH POLYMERS HAS GREATLY IMPROVED DURABILITY AND STRENGTH. POLYMER-IMPREGNATED CONCRETE SHOWS PROMISE FOR USE IN DESALTING PLANTS, PRECAST TUNNEL LINERS, CONCRETE PIPE, PILES, BRIDGE DECKS, AND IN MANY OTHER STRUCTURES EXPOSED TO HARSH CONDITIONS. DEVELOPMENT OF POLYMER-IMPREGNATED CONCRETE REQUIRES NEW METHODS AND NEW APPLICATIONS OF LABORATORY ANALYTICAL TECHNIQUES TO ENSURE UNIFORMLY GOOD QUALITY. THESE METHODS INCLUDE SONIC MEASUREMENTS, DIELECTRIC MEASUREMENTS, THERMOVISION, NEUTRON RADIOGRAPHY, ELECTRON MICROSCOPY, INFRARED SPECTROSCOPY, AND THERMAL ANALYSIS.

THE INSTALLATION RATE FOR THESE REACHES WAS ABOUT 4 FT/MIN, 2 TO 3 TIMES FASTER THAN FOR EQUIVALENT LENGTHS OF CONCRETE OR CLAY PIPE. PHASE 2 WAS TO LOCATE A MACHINE CAPABLE OF LAYING TUBING AT A FASTER RATE. ONE MACHINE HAVING THIS POTENTIAL IS A GERMAN-MADE, HOES GIGANT TRENCHER, USED IN A FIELD DEMONSTRATION NEAR COURTLAND, KANS, TO INSTALL 2,000 FT OF POLYETHYLENE TUBING. THE DRAINS WERE INSTALLED 7.5 FT DEEP, WITH GRAVEL ENVELOPE, AT AN AVERAGE RATE OF 15 FT/MIN. THIS DEMONSTRATION INDICATED THAT BY USING NEW PIPE MATERIALS AND HIGH SPEED TRENCHING MACHINES, DRAINAGE COSTS MAY BE REDUCED. (USBR) JF - RECLAMATION ERA, VOL. 57, NO. 4, P 14-20, NOV 1971. 7 FIG.

THE WWS IS A COMPLETE RECONNAISSANCE TO DEVELOP A GENERAL PLAN WITH THE FOLLOWING OBJECTIVES: (1) TO PROJECT THE FUTURE POPULATION, INDUSTRY, AGRICULTURE, ENVIRONMENT, AND SOCIAL MAKEUP OF THE WEST, (2) TO DETERMINE POTENTIAL WATER SUPPLY FROM ALL AVAILABLE SOURCES, (3) TO TRANSLATE PROJECTIONS OF FUTURE CONDITIONS INTO WATER REQUIREMENTS AND BALANCE THESE REQUIREMENTS AGAINST AVAILABLE AND POTENTIAL WATER SUPPLY, AND (4) TO DEVELOP AN OPTIMUM PLAN TO MEET THESE NEEDS. THE WWS ORGANIZATION CONSISTS OF 4 BASIC GROUPS: POLICY, ADVISORY, MANAGEMENT, AND IMPLEMENTATION. THESE GROUPS WILL STUDY SEVERAL WATER RESOURCE POTENTIALS, INCLUDING WEATHER MODIFICATION, DESALTING, GEOTHERMAL DEVELOPMENT, AND WASTEWATER RECLAMATION; AND CONSIDER THE PROTECTION AND ENHANCEMENT OF THE ENVIRONMENT DURING DEVELOPMENT. FINDINGS AND RECOMMENDATIONS WILL PROVIDE NEW PERSPECTIVES ON WATER RESOURCE DEVELOPMENT AND WILL HAVE AN IMMEASURABLE INFLUENCE ON WESTERN AND NATIONAL GROWTH FOR MANY YEARS.

THE PREDOMINATELY AMPHIBOLITE ROCK FOUNDATION MASS WAS THOROUGHLY INVESTIGATED AND IS CHARACTERIZED BY NUMEROUS JOINTS, SHEARS, TALC SEAMS, AND FAULTS. THE IN SITU INVESTIGATION INCLUDED TESTS OF DIRECT SHEAR, CYLINDRICAL AND UNIAXIAL JACKING, PLATE GOUGE JACKING, AND STRESS RELIEF. LABORATORY INVESTIGATIONS INCLUDED STANDARD PROPERTY AND DIRECT SHEAR TESTS. INDIVIDUAL FOUNDATION BLOCKS AND GROUPS OF BLOCKS WERE ANALYZED FOR STABILITY AND COMPATIBILITY OF DEFORMATIONS UNDER LOADINGS FROM THE DAM AND RESERVOIR. THE DEFORMATION MODULI OF THE FOUNDATION WERE DETERMINED BY COMBINING TEST RESULTS AND ANALYTIC PROCEDURES. DEFORMATION MODULI FOR LOCAL MASSES OF ROCK WERE EVALUATED FROM IN SITU JACKING TESTS. A JOINT-SHEAR INDEX WAS DEVELOPED TO RELATE THESE MODULI TO LABORATORY CORE TESTS. THE INDEX WAS USED TO DETERMINE DEFORMATION MODULI IN LOCAL ROCK MASSES THROUGHOUT THE FOUNDATION. THESE MODULI WERE FURTHER MODIFIED TO ACCOUNT FOR DISCONTINUOUS SHEARS. THE MODULI FROM THE LOCAL ROCK MASSES WERE COMBINED WITH MODULI FROM MAJOR FAULTS AND SHEARS IN A FINITE ELEMENT SOLUTION TO DETERMINE EFFECTIVE DEFORMATION MODULI THROUGHOUT THE FOUNDATION.

AN UPLIFT LOAD WAS APPLIED TO EACH FOOTING AND VERTICAL AND HORIZONTAL MOVEMENTS AND ROTATIONS WERE MEASURED. THE FOOTING TYPES TESTED WERE: (1) ANCHOR BAR--A CONCRETE CAP CONNECTED TO 4 REINFORCED GROUT COLUMNS, (2) PRESSED PLATE--A STEEL PLATE AND STEM PLACED IN COMPACTED SOIL, AND (3) SCREW ANCHOR--A CONCRETE CAP CONNECTED TO 3 OR 4 STEEL SCREW ANCHORS. GENERALLY, SCREW ANCHOR FOOTINGS WERE THE MOST RESISTANT TO MOVEMENT UNDER LOAD, FOLLOWED BY THE PRESSED PLATE, AND THEN THE ANCHOR BAR. THREE INDIVIDUAL VERTICAL ANCHOR BAR COLUMNS ALSO WERE TESTED. ANALYSES INDICATED THESE COLUMNS RESISTED MORE THAN 3 TIMES THE PREDICTED UPLIFT LOADS. THE RESULTS APPEAR TO INDICATE THAT LATERAL PRESSURES IN THE DUNE SAND INCREASED CONSIDERABLY AS THE COLUMNS MOVED THROUGH THE SOIL. FURTHER RESEARCH IS NEEDED TO ACCURATELY PREDICT THE MOVEMENT OF FOOTINGS UNDER UPLIFT LOADS. (USBR) JF - BUREAU OF RECLAMATION REPORT REC-ERC-71-40, OCT. 1971. 41 P, 43 FIG, 2 TAB, 9 REF, APPEND.

PA CONCRETE IS PLACED BY FILLING THE FORMS WITH CLEAN, PROPERLY GRADED COARSE AGGREGATE AND THEN INJECTING A STRUCTURAL-QUALITY GROUT INTO THE VOIDS. A HIGHER PERCENTAGE OF COARSE AGGREGATE IN POINT-TO-POINT CONTACT CAUSES PA CONCRETE TO HAVE A HIGHER MODULUS OF ELASTICITY THAN CONVENTIONAL CONCRETE.

WITH A PROPERLY PROPORTIONED GROUT MIX AND GOOD CONSTRUCTION PRACTICES, THE SAME ALLOWABLE WORKING STRESSES CAN BE USED WITH PA CONCRETE AS WITH CONVENTIONAL CONCRETE. TO PRODUCE SATISFACTORY PA CONCRETE: (1) THE COARSE AGGREGATE SHOULD BE CLEAN, (2) THE VOID CONTENT OF THE AGGREGATE IN PLACE SHOULD BE 38 TO 48%, (3) THE GROUT MUST HAVE THE PROPER FLUIDITY AND STRENGTH, (4) THE FORMS SHOULD BE OF GOOD QUALITY TO PREVENT LEAKAGE, AND (5) RELIABLE GROUT PIPING SYSTEMS AND GROUTING METHODS MUST BE USED.

A SHORT DISTANCE DOWNSTREAM, LEAKAGE INTO THE UNDERGROUND POWERPLANT DRAINAGE TUNNEL REACHED 429 GPM. A CATIONIC ASPHALT EMULSION GROUT, TRIGGERED WITH A HYDRATED LIME SLURRY, WAS CHOSEN TO PLUG THE LARGE FLOWING WATER CHANNELS. SEVERAL TYPES OF PUMPS WERE UNSATISFACTORY FOR INJECTING THE ASPHALT EMULSION INTO NX-SIZE HOLES; AIR-PRESSURIZED TANKS WERE MORE EFFECTIVE. INJECTION OF 10,000 GAL OF ASPHALT EMULSION REDUCED LEAKAGE INTO THE POWERPLANT DRAINAGE TUNNEL BY APPROXIMATELY 65%. THE LONG-TERM EFFECTIVENESS OF THE ASPHALT EMULSION INJECTION WAS DIFFICULT TO EVALUATE BECAUSE THE RESERVOIR WAS BEING LOWERED DURING THE INJECTION AND REMAINED LOW UNTIL AFTER THE CEMENT GROUTING. 7,823 SACKS OF CEMENT WERE USED TO GROUT 3,696 FT OF EX-SIZE GROUT HOLE. LONG STRINGS OF ASPHALT EJECTED FROM HOLES DURING THE ASPHALT GROUTING AND SUBSEQUENT CEMENT GROUTING, INDICATED THAT THE ASPHALT RESIDUE WAS PLASTIC RATHER THAN HARD.

THE HETRONGENITY OF THE FOUNDATION REQUIRED DEVELOPMENT OF METHODS FOR EVALUATING DEFORMATION MODULI THROUGHOUT THE FOUNDATION, INCLUDING EFFECTS OF MINOR DISCONTINUITIES IN A ROCK MASS. THE EFFECTS OF JOINTS, BREAKS ALONG CLEAVAGE, AND SHEARS WERE QUANTIFIED, AND THEIR FREQUENCY AND DISTRIBUTION WERE USED TO DETERMINE THE ROCK DEFORMATION MODULUS. THE PRIMARY METHOD USED WAS THE JOINT-SHEAR INDEX GIVING A NUMERICAL VALUE TO EACH DISCONTINUITY ACCORDING TO TYPE, CONDITION, AND LOCATION. THE INDEX IS THE SUM OF THE VALUES OF ALL WEIGHTED DISCONTINUITIES OBSERVED IN THE CORE TAKEN FROM AN INSTRUMENTATION HOLE. THE RATIO OF IN SITU DEFORMATION MODULUS TO ELASTIC CORE MODULUS CORRELATED EXCELLENTLY WITH THE JOINT-SHEAR INDEX. THIS CORRELATION ENABLED PREDICTION OF THE REDUCTION IN MODULUS AT ANY DRILL HOLE LOCATION OVER THE ENTIRE LENGTH OF HOLE.

TECHNOLOGICAL PROWESS MUST BE APPLIED IN HARMONY WITH SOCIAL AND ENVIRONMENTAL GOALS TO ACHIEVE THIS BALANCED GROWTH. TODAY'S WATER PROGRAM IS CHARACTERIZED BY A POLARIZATION OF VIEWS--THE DEVELOPERS ON ONE SIDE AND THE PRESERVATIONISTS ON THE OTHER. BASIC COMMUNICATION BETWEEN THEM IS THE NEWS MEDIA AND/OR THE COURTS. COMBINING ENVIRONMENTAL AND ECONOMICAL VALUES IN A PROPER BALANCE CAN RESULT IN THE GOOD LIFE. TO PARTICIPATE IN REASSESSMENT OF WATER PLANNING, THE BUREAU OF RECLAMATION HAS ESTABLISHED A SPECIAL STUDIES PROGRAM TO: (1) PREPARE GUIDELINES FOR MULTIOBJECTIVE PLANNING, (2) EVALUATE PROCEDURES FOR ENHANCING EFFICIENCY AND CAPABILITY, (3) EXAMINE SYSTEMS ANALYSIS AS AN IMPROVED PLANNING TOOL, (4) ANALYZE BUDGETS AND SCHEDULES, AND (5) REVIEW ECONOMIC ISSUES AND CONCEPTS. DATA FROM AN INVENTORY BEING COMPILED OF WATER NORMALLY WASTED TO THE OCEAN, STREAMS, OR LAKES WILL BE ANALYZED TO IDENTIFY OPPORTUNITIES FOR RECYCLING AND REUSE, AN IMPORTANT METHOD OF STRETCHING LIMITED WATER SUPPLIES. IMPROVED PROCEDURES ARE NEEDED FOR PROJECTING PROBLEMS, NEEDS, AND REQUIREMENTS.

WHEN EVIDENCE EXISTS THAT A PROJECT HAS PROMISE AFTER A RECONNAISSANCE INVESTIGATION, AUTHORITY FOR A FEASIBILITY INVESTIGATION IS REQUESTED OF CONGRESS. THE FEASIBILITY INVESTIGATION TESTS THE ENGINEERING, ECONOMIC, FINANCIAL AND EFFECT ON ENVIRONMENT ASPECTS OF THE PROPOSED PROJECT. ALL OF THESE MUNICIPAL WATER PROJECTS ARE MULTIPURPOSE PROJECTS. THE PURPOSES OTHER THAN M AND I SUCH AS FLOOD CONTROL, FISH AND WILDLIFE, AND RECREATION NORMALLY SHARE THE HIGH COST OF PRESENT DAY WATER RESOURCE DEVELOPMENT. THE REIMBURSABLE MUNICIPAL AND INDUSTRIAL WATER SUPPLY COST ALLOCATION IS DETERMINED THROUGH AN EQUITABLE ALLOCATION PROCEDURE. THE M AND I ALLOCATION IS REIMBURSABLE WITH INTEREST OVER A PERIOD OF NOT MORE THAN 50 YEARS. THE OTHER PURPOSES CITED ARE NONREIMBURSABLE EXCEPT FOR THOSE PROJECTS TO WHICH THE FEDERAL WATER PROJECT RECREATION ACT APPLIES.

MAJOR ICING CONDITIONS THAT HAVE OCCURRED ON BUREAU OF RECLAMATION PROJECTS ARE REVIEWED. FORMATION OF FRAZIL ICE, BORDER ICE, AND ICE COVER IS EXPLAINED. THE STABILITY OF ICE COVER IS REVIEWED AND EQUATIONS DEVELOPED RELATING TO THICKNESS OF THE UPSTREAM EDGE OF THE ICE COVER TO A MODIFIED FROUDE NUMBER. ROUGHNESS COEFFICIENTS FOR THE UNDER SURFACE OF AN ICE COVER ARE DISCUSSED. GENERALLY, THE COEFFICIENTS GRADUALLY DECREASE DURING THE WINTER. THE MAXIMUM COEFFICIENT IS OBSERVED DURING THE FIRST 3 DAYS OF FREEZEUP. AN EQUATION FOR DETERMINING THE COEFFICIENT OF ROUGHNESS IS GIVEN. AS THE COVER OF ICE JAMS FORM IN A NATURAL RIVER, THE ICE PRODUCTS ADDED HEAD LOSS AND THE UPSTREAM WATER LEVELS RISE, CAUSING FLOODING.

THE MATHEMATICAL MODEL PREDICTED THAT THE RESERVOIR WOULD BE STRATIFIED DURING A FEW MONTHS IN THE SPRING BUT WOULD BE ISOTHERMAL DURING THE SUMMER AND FALL. EFFECTS OF AN EXISTING BARRIER DAM WERE ESTIMATED BY MATHEMATICAL AND PHYSICAL MODELS. STRATIFICATION PATTERNS UPSTREAM FROM THE BARRIER, PREDICTED BY THE MATHEMATICAL MODEL, WERE USED IN A 1:60 HYDRAULIC MODEL TO STUDY CONDITIONS DOWNSTREAM FROM THE BARRIER. THE BARRIER ACTED AS A SKIMMER, CAUSING THE FLOW OF WARMER WATER FROM HIGHER LEVELS IN THE RESERVOIR TO ENTER THE REGION DOWNSTREAM FROM THE BARRIER. THE RIVER OUTLETS AND MUNICIPAL OUTLET OPERATION IN DRAWING DOWN THE ISOTHERMS CAUSED WARMER TEMPERATURES OF WITHDRAWAL AT THE HATCHERY OUTLETS. A HIGHER HATCHERY OUTLET WAS RECOMMENDED, IN ADDITION TO THE 3 HATCHERY OUTLETS INCLUDED IN THE PRELIMINARY DESIGN.

PROBABLY THE BEST APPROACH TO THE PROBLEM OF WATER, MAN, AND NATURE IS AN INTERDISCIPLINARY ONE, AND MAY BE THE ONLY ONE THAT HAS A REASONABLE CHANCE OF CONSISTENT SUCCESS. UP TO THE TURN OF THE CENTURY, MOST WATER PROJECTS WERE SINGLE-PURPOSE AND LOCALLY ORIENTED. THEY WERE BUILT TO SOLVE PROBLEMS OF WATER SUPPLY OR CONTROL; THEIR EFFECTS BEYOND THE LOCAL AREA WERE NEGLIGIBLE. THE HAVE BEEN LARGELY SUCCESSFUL; BUT, AS WATER PROJECTS BEGAN TO GROW IN SIZE AND SCOPE, SIDE EFFECTS SUCH AS FISH AND WILDLIFE DEPRESSION, DRAINAGE CONTAMINATION, AND OTHERS, HAD TO BE CONSIDERED. SOME BUREAU PROJECTS ARE GIVEN TO EXEMPLIFY THE INDEPENDENT AND INTERDISCIPLINARY APPROACHES TO WATER PROJECTS. WHEN BIOLOGISTS AND ENGINEERS POOLED THEIR TALENTS, SUCCESS HAS BEEN CONSISTENT. WHEN INTERDISCIPLINARY COOPERATION BROKE DOWN OR DID NOT EXIST, LIMITED SUCCESS WAS ACHIEVED AT THE COST OF LOST OPPORTUNITIES FOR BETTER WATER USAGE. CHANGES ARE TAKING PLACE RAPIDLY IN WATER RESOURCE DEVELOPMENT POLICIES, AND THE AMERICAN PUBLIC IS BEGINNING TO EXPECT SYNERGISTIC RESULTS.

THIS METHOD PROVIDES THE DESIGNER WITH A RANGE OF FRICTION ANGLES AND COHESION INTERCEPTS AND IS CONSIDERED A SUPERIOR METHOD FOR MOST PROBLEMS AND DESIGN APPLICATIONS. THE PROCEDURES, RESULTS, AND INTERPRETATIONS OF 4 TESTS AT GRAND COULEE THIRD POWERPLANT AND 2 TESTS AT AUBURN DAM ARE GIVEN. AFTER ROCK EXCAVATION, NORMAL AND SHEAR FORCES ARE APPLIED TO OBTAIN THE INITIAL SHEAR TEST RESULTS. SLIDING RESISTANCE TESTS ARE THEN PERFORMED BY SHEARING THE DISTURBED SAMPLE UNDER A SERIES OF NORMAL FORCES. ASSUMING COHESION IS NEARLY ZERO AFTER THE INITIAL SHEAR TEST, THE ANGLE OF SLIDING FRICTION FORCE TO NORMAL FORCE CAN BE DETERMINED FOR EACH SLIDING RESISTANCE TEST AND AN ENVELOPE CAN BE DRAWN USING THE MAXIMUM AND MINIMUM ANGLES. BASED ON HIS DESIGN PHILOSOPHY, THE DESIGNER CAN CHOOSE THE DESIRED VALUES. THE RESULTS COMPARE CLOSELY WITH THE COULOMB-NAVIER ANALYSIS.

SOME HYDROETEOROLOGICAL FACTORS CONSIDERED IN CHOOSING THE TARGET AREA ARE PRESENTED. THE OPERATIONAL USE OF WEATHER MODIFICATION ON A LARGE SCALE RAISES DIFFICULT QUESTIONS ABOUT LEGAL RESPONSIBILITIES, CONFLICTING SOCIAL DESIRES, AND APPROPRIATE GOVERNMENTAL REGULATORY ACTIVITIES. HYDROMETEOROLOGY WILL SUPPLY THE FACTUAL BASIS FOR DECISIONMAKING IN EACH PROBLEM AREA. HISTORICALLY, EVALUATION OF THE EFFECTS OF WEATHER MODIFICATION HAS BEEN THE WEAK LINK BETWEEN THE WEATHER MODIFIER AND THE PUBLIC.

OF PARTICULAR CONCERN WERE THE VELOCITY DISTRIBUTION AND TURBULENCE CONDITIONS AT THE TRASHRACK LOCATION DURING THE PUMPING CYCLE. THE STUDIES SHOWED THAT THE FLOW WAS NOT EVENLY DISPERSED IN THE INITIAL STRUCTURE WHICH HAD 20.5 DEG DIVERGING SIDEWALLS AND PARALLEL FLOOR AND ROOF. AUXILIARY PIERS AND HORIZONTAL AND VERTICAL DEFLECTORS IMPROVED THE VELOCITY DISTRIBUTION, BUT THE VELOCITY DISTRIBUTION CHANGED SO RADICALLY FOR A SMALL CHANGE IN PIER LOCATION THAT THEY WERE NOT USED. THREE ADDITIONAL INTAKE-OUTLET STRUCTURES WITH LESSER SIDEWALL DIVERGENCE WERE STUDIED. ULTIMATELY SELECTED WAS A STRUCTURE WITH 13 DEG 10 MIN DIVERGING SIDEWALLS AND 5 DEG DIVERGENCE IN THE FLOOR AND ROOF. PRIMARILY FOR STRUCTURAL REASONS, THE STRUCTURE INCLUDED ONE PIER AT THE PENSTOCK END AND THREE PIERS AT THE RESERVOIR END. FLOW DISTRIBUTION WAS ADEQUATE. ALTHOUGH VELOCITIES VARIED FROM 1.0 FPS TO ABOUT 12.5 FPS IN DIFFERENT TRASHRACK SECTIONS, THE VELOCITY DIFFERENCE IN ANY ONE SECTION WAS USUALLY CONSISTENT. HEAD LOSSES IN THE STRUCTURE WERE FROM 0.6 TO 0.77 OF A VELOCITY HEAD DURING THE PUMPING CYCLE, AND ABOUT 0.19 OF A VELOCITY HEAD DURING THE GENERATION CYCLE.

INSTALLATION OF A CONVENTIONAL HYDRAULIC JUMP STILLING BASIN OR FLIP BUCKET TO HANDLE THE DESIGN FLOOD WAS IMPRACTICAL BECAUSE OF POOR FOUNDATION CONDITIONS. HOWEVER, PRELIMINARY INVESTIGATIONS SHOWED THAT IF THE ALLOWABLE UNIT DISCHARGE OF A BAFFLED APRON DROP COULD BE INCREASED FROM 60 CFS/FT OF WIDTH TO ABOUT 80 CFS, SUCH A STRUCTURE COULD BE BUILT ON SOUND ROCK. HYDRAULIC MODEL STUDIES WERE PERFORMED TO CONFIRM A DESIGN FOR A BAFFLED APRON DROP BASED ON A UNIT DISCHARGE OF 77.7 CFS/FT OF WIDTH. THE TESTS SHOWED THAT THE HIGHER CAPACITY STRUCTURE WAS AN EFFECTIVE AND SAFE ENERGY DISSIPATOR, AND COULD HANDLE UNIT DISCHARGES UP TO TWICE THE DESIGN DISCHARGE. THE EFFECT OF BAFFLE PIER LOCATION ON THE RESERVOIR ELEVATION FOR MAXIMUM DISCHARGE WAS DETERMINED. AN OPTIMUM CONFIGURATION FOR THE CHANNEL BED DOWNSTREAM OF THE CONCRETE APRON WAS DEVELOPED TO PREVENT EROSION OF THE APRON.

These are north to south from the Savannah River Entrance to the St. Marys River Entrance: Wassaw Sound, Ossabaw Sound, St. Catherines Sound, Sapelo Sound, Doboy Sound, Altamaha Sound, St. Simons Sound, and St. Andrews Sound. Salt water is diluted by fresh water from the Savannah, Ogeechee, Altamaha, Satilla, and St. Marys rivers. The coastal or inshore waters extend from the mounts of the sounds and from the barrier beaches to a depth of about 60 feet. The offshore waters of the continental shelf lie beyond. The continental shelf along the Georgia coast is 70 to 80 miles wide with a gentle slope of about two feet per mile. Information on the physical characteristics, sediments, fauna, fishery resources, productivity and energy flow, and food webs is outlined.

SPILLWAY OPERATION AND DAMAGE, AND SUBSEQUENT MODEL TESTS, REPAIRS, MODIFICATIONS, AND PROTOTYPE TESTS ARE DESCRIBED. CAVITATION INITIATED BY SURFACE IRREGULARITIES IN THE TUNNEL LINING CAUSED THE DAMAGE. HEAVIEST DAMAGE WAS CONCENTRATED IN THE VERTICAL BEND OF THE TUNNEL AND THE NEAR HORIZONTAL REACH JUST DOWNSTREAM FROM THE BEND. REPAIRS CONSISTED OF BACKFILL CONCRETE IN THE HEAVILY DAMAGED AREAS AND APPLICATION OF AN EPOXY-BONDED EPOXY-MORTAR VENEER TO COVER MINOR SURFACE IRREGULARITIES. MODIFICATION CONSISTED OF CONSTRUCTING AN AIR SLOT TO INTRODUCE AIR ALONG THE FLOW SURFACES OF THE VERTICAL BEND. MODEL TESTS OF THE TUNNEL SHOWED THAT THE OPTIMUM LOCATION OF THE AIR SLOT WAS JUST UPSTREAM FROM THE VERTICAL BEND. THE AIR SLOT PROVIDED POSITIVE AIR INDUCTION ALONG THE FLOW SURFACES AND WORKED SATISFACTORILY FOR ALL RANGES OF DISCHARGE.

THE PROJECT INVOLVES BRINGING WATER FROM THE MOUNTAINS ON THE WEST SLOPE OF THE CONTINENTAL DIVIDE THROUGH A TUNNEL TO THE EAST SIDE WHERE IT WILL SUPPLEMENT THE ARKANSAS RIVER FOR IRRIGATION, MUNICIPAL, AND INDUSTRIAL NEEDS. STUDIES WERE PERFORMED ON A 1:56 SCALE HYDRAULIC MODEL OF PUEBLO DAM SPILLWAY AND PLUNGE BASIN TO DETERMINE IF THE UNUSUAL DESIGN COULD HANDLE THE REQUIRED RELEASES SAFELY. THE MODEL CONTAINED THE FLIP-TYPE SPILLWAY, PLUNGE BASIN, RIVER OUTLETS, AND A SECTION OF DOWNSTREAM RIVER CHANNEL. CHANNEL EROSION, BASIN IMPACT PRESSURES, NAPPE OSCILLATIONS, CREST RATING, AND FLOW PROFILE STUDIES WERE MADE. FLOW SPLITTERS WERE ADDED TO THE SPILLWAY TO ELIMINATE NAPPE OSCILLATIONS. THE PLUNGE BASIN INITIALLY CONTAINING 2 FLOOR ELEVATIONS WAS ENLARGED TO THE LEVEL OF THE DEEPER SECTION TO MINIMIZE IMPACT PRESSURES. A TECHNIQUE OF DATA COLLECTION WAS USED IN OBTAINING IMPACT PRESSURES WHICH PROVIDED AN ELECTRONIC STATISTICAL ANALYSIS. A CURVE WAS OBTAINED TO RELATE BASIN FLOOR EFFECTIVE PRESSURE HEAD TO SPILLWAY DISCHARGE FOR THE NORMAL RIVER TAILWATER CONDITIONS.

THE MODEL WAS AT A 1.24 SCALE AND INCLUDED THE INLET-OUTLET STRUCTURE, A RECTANGULAR-TO-CIRCULAR TRANSITION, AND THE PENSTOCK DOWN TO THE SPIRAL CASE. VELOCITY DISTRIBUTION AND HEAD LOSS MEASUREMENTS WERE MADE FOR THE PENSTOCK AND INLET-OUTLET STRUCTURE. TWO VERTICAL WALLS WERE PLACED IN THE STRUCTURE TO IMPROVE THE HORIZONTAL VELOCITY DISTRIBUTION AT THE TRASHRACK POSITION. A LOW-VELOCITY AREA WAS REMOVED BY MAKING THE FLOOR OF THE STRUCTURE NONDIVERGENT. THE STRUCTURE WAS THEN LENGTHENED TO RESTORE THE INITIAL TRASHRACK AREA.

OF PARTICULAR CONCERN WERE THE VELOCITY DISTRIBUTION AND TURBULENCE CONDITIONS AT THE TRASHRACK LOCATION DURING THE PUMPING CYCLE. THE STUDIES SHOWED THAT THE FLOW WAS NOT EVENLY DISPERSED IN THE INITIAL STRUCTURE WHICH HAD 20.5 DEG DIVERGING SIDEWALLS AND PARALLEL FLOOR AND ROOF. THREE ADDITIONAL INTAKE-OUTLET STRUCTURES WITH LESSER SIDEWALL DIVERGENCE WERE STUDIED. ULTIMATELY SELECTED WAS A STRUCTURE WITH 13 DEG 10 MINUTE DIVERGING SIDEWALLS AND 5 DEG DIVERGENCE IN THE FLOOR AND ROOF. PRIMARILY FOR STRUCTURAL REASONS, THE STRUCTURE INCLUDED ONE PIER AT THE PENSTOCK END AND THREE PIERS AT THE RESERVOIR END. FLOW DISTRIBUTION WAS ADEQUATE. ALTHOUGH VELOCITIES VARIED FROM 1.0 FPS TO ABOUT 12.5 FPS IN DIFFERENT TRASHRACK SECTIONS, THE VELOCITY DIFFERENCE IN ANY ONE SECTION WAS USUALLY CONSISTENT. HEAD LOSSES IN THE STRUCTURE WERE FROM 0.6 TO 0.77 OF A VELOCITY HEAD DURING THE PUMPING CYCLE, AND ABOUT 0.19 OF A VELOCITY HEAD DURING THE GENERATION CYCLE.

CHARACTERISTICS OF DUNE STRUCTURES WERE EXAMINED IN THE FIELD BY INTRODUCING MARKER BEDS OF MAGNETITE AT TIMES OF SAND DEPOSITION, THUS RECORDING ORIGINAL SURFACES AND MAKING POSSIBLE THE DETERMINATION OF SUBSEQUENT CHANGES. AVALANCHING IN SAND IS OF TWO TYPES: SAND FLOW AND SLUMPING. DEFORMATIONAL STRUCTURES CHARACTERISTIC OF EACH WERE RECORDED IN THE FIELD AND WERE REPRODUCED IN THE LABORATORY. ANALYSIS OF THESE STRUCTURES SUGGESTS CRITERIA FOR DISTINGUISHING COMPRESSIONAL TYPES (LOWER DUNE SLOPE) FROM TENSIONAL TYPES (UPPER DUNE SLOPE). THE ANALYSIS OF DEFORMATIONAL STRUCTURES ALSO SERVES TO DISTINGUISH BETWEEN FORMS DEVELOPED IN COHESIVE SAND AND THOSE IN NON-COHESIVE SAND. SINCE THE DEGREE OF COHESION IS LARGELY A FUNCTION OF THE AMOUNT OF MOISTURE IN THE SAND THE STRUCTURES PROVIDE A MEANS FOR RECOGNIZING ORIGINAL MOISTURE CONTENT.

THE BOLTS WERE INSTALLED IN THE NAVAJO SANDSTONE AT GLEN CANYON DAM, ARIZ. LOAD CELLS FOR THE BOLTS WERE CALIBRATED FOR 10 LOADS RANGING FROM 0 TO 25,000 LB. INITIAL LOADS ON THE BOLTS VARIED FROM 9,000 TO 12,000 LB. TWO BOLTS WERE NOT ANCHORED PROPERLY TO THE ROCK AND WOULD NOT ACCEPT THE DESIRED LOAD. LOAD-TIME GRAPHS ARE PRESENTED FROM THE TIME OF INITIAL LOADING IN OCT 1968 TO DEC 1970. LOAD CELLS SHOWED A LOAD RELAXATION IN THE BOLTS FOR 11 DAYS AFTER LOADING; RELAXATION VARIED FROM 17 TO 44% OF THE INITIAL LOAD. LOADS CARRIED BY THE BOLTS DROPPED SLIGHTLY OVER A 1-YR CYCLE OF TEMPERATURE STRESSING, BUT LEVELED OUT IN SUBSEQUENT YEARS.

A SECOND INSTALLATION IN OPERATION FOR ONE SEASON CONTROLS RELEASES TO THE MAIN SUPPLY CANALS FROM THE DIVERSION DAM. INFORMATION ON THE ECONOMICS FOR SELECTING SUCH A SYSTEM, AND A DESCRIPTION OF THE EQUIPMENT INSTALLED ARE PRESENTED. AUTOMATION OF WATER SUPPLY AND DISTRIBUTION SYSTEMS FOR AN IRRIGATION UNIT REQUIRES CONSIDERABLE STUDY. A DETAILED OPERATING PLAN MUST INCLUDE SUCH DATA AS CANAL SIZE, CONTROL STRUCTURE LOCATION, WEATHER RECORDS, AND PLANNED OPERATING STAFF. MAIN POINTS OF CONTROL THAT MUST BE DETERMINED ARE: RESERVOIR HEADWORKS, PRINCIPAL CANAL HEADWORKS, KEY CHECKS, AND WASTEWAYS. A COST STUDY MUST BE MADE TO DETERMINE WHETHER THE PROPOSED INSTALLATION WILL RESULT IN AN OPERATIONAL SAVINGS IN MANPOWER AND WATER.

AN OPEN AND CLOSED CONDUIT SYSTEMS INVESTIGATION OF FOUR PROPRIETARY MATERIALS PROPOSED AS CANAL SOIL SEALANTS ON SILTY SAND IN LABORATORY PERMEAMETERS AN - 19010709; 7110201 AB - FOUR PROPRIETARY MATERIALS PROPOSED FOR CANAL SEALANTS WERE EVALUATED IN THE BUREAU OF RECLAMATION LABORATORY. TESTS ON SILTY SAND SPECIMENS OF 12-IN. (30.5-CM) LENGTH WERE CONDUCTED IN 1-IN. (2.5-CM)-DIA PLASTIC PERMEAMETER TUBES. PERMEABILITY RATES OF THE SOIL SPECIMENS WERE DETERMINED BEFORE AND AT TIME INTERVALS AFTER TREATMENT. TREATMENTS AT RATES FROM 50 TO 800 LB/ACRE (56 TO 896 KG/HA) WERE GENERALLY ACCOMPLISHED BY MIXING THE SEALANTS WITH WATER AND PONDING THEM OVER THE SOIL SPECIMEN SURFACES. INCREMENTS OF THE SOIL WERE REMOVED FROM A SPECIMEN TOP UNTIL THE PERMEABILITY ROSE TO THE ORIGINAL PRETREATMENT RATE. THE TOTAL DEPTH OF SOIL REMOVED WAS CONSIDERED TO BE THE EFFECTIVE DEPTH OF PENETRATION FOR THE SEALANT. ONE SEALANT, APPLIED AT THE RATE OF 100 LB/ACRE (112 KG/HA), SIGNIFICANTLY REDUCED SOIL PERMEABILITY AND PENETRATED THE SOIL AT LEAST 2 IN. (5.1 CM). THIS SEALANT IS RECOMMENDED FOR FURTHER TESTING IN OTHER SOIL CONDITIONS. ANOTHER SEALANT REDUCED PERMEABILITY BUT DID NOT PENTRATE THE SOIL. THE REMAINING 2 SEALANTS DID NOT SIGNIFICANTLY REDUCE THE PERMEABILITY RATE. IN SEVERAL TESTS, SEALANTS THAT SWELL INTO SOFT GELS WHEN WETTED WERE SPREAD ON THE SOIL SURFACES. THE GELS DID NOT SEAL THE SOIL AS WELL AS SEALANTS APPLIED MIXED WITH WATER. JF - AVAILABLE FROM THE NATIONAL TECHNICAL INFORMATION SERVICE AS PB-197 911, $3.00 IN PAPER COPY, $0.95 IN MICROFICHE.

THREE MATERIALS BEING INVESTIGATED ARE: (1) POLYMER-IMPREGNATED CONCRETE (PIC - PRECAST PORTLAND CEMENT CONCRETE IMPREGNATED BY A MONOMER SYSTEM WHICH IS SUBSEQUENTLY POLYMERIZED IN SITU); (2) POLYMER-CEMENT CONCRETE (PCC - MONOMER IS ADDED DURING MIXING OF PORTLAND CEMENT, WATER, AND AGGREGATE, FOLLOWED BY POLYMERIZATION); AND (3) POLYMER-CONCRETE (PC - A COMPOSITE FORMED BY POLYMERIZING A MONOMER AND AGGREGATE MIXTURE). INVESTIGATIONS INDICATE THAT THE MOST SUCCESSFUL CONCRETE-POLYMER MATERIAL FOR CONSTRUCTION IS PIC, BUT PRESENT STUDIES ARE INCLUDING PC AND PCC BECAUSE OF POTENTIAL APPLICATIONS IF FEASIBLE FABRICATION METHODS CAN BE DEVELOPED. COMPARED TO CONVENTIONAL CONCRETE, PIC SHOWS IMPRESSIVE IMPROVEMENTS IN STRENGTH AND DURABILITY. TESTS SHOW THAT PIC MADE WITH ORDINARY CONCRETE HAS ESSENTIALLY THE SAME PROPERTIES AS PIC MADE WITH A MORE EXPENSIVE HIGH-STRENGTH CONCRETE. APPLICATIONS FOR PIC BEING INVESTIGATED ARE DESALTING PLANTS, DRAINTILE, CULVERT AND SEWER PIPE, BEAMS AND WALL PANELS IN HOUSING, BRIDGE DECKS, ROADS, LUMINARIES, AND UNDERWATER STRUCTURES.

PURPOSE OF THE RESEARCH WAS TO DEVELOP A METHOD FOR MAKING DISCHARGE MEASUREMENTS ACCURATELY, QUICKLY, AND WITH A MINIMUM OF PERSONNEL AND EQUIPMENT. MEASUREMENTS WERE MADE ON THE FLATIRON POWER AND PUMPING PLANT PENSTOCK TO COMPARE THE RELATIVE ACCURACY OF USING THE RADIOISOTOPE-VELOCITY, INTEGRATED SAMPLE, DILUTION, AND TOTAL-COUNT METHODS. MEASURING EQUIPMENT WAS INSTALLED AT THE POLE HILL POWERPLANT FOR MEASURING TURBINE DISCHARGE AT THE SINGLE-UNIT PLANT. RESULTS INDICATED NO SUPERIORITY OF ANY OF THE 3 METHODS USED TO MEASURE THE DISCHARGE RADIOISOTOPE. DISCHARGE MEASUREMENTS SHOWED CONSISTENT RESULTS WITH AN ACCURACY OF PLUS OR MINUS 1.5%. GENERAL OBSERVATIONS ARE GIVEN FOR ALL 4 RADIOISOTOPE MEASUREMENT METHODS.

STREAMSIDE INSTRUMENTATION AUTOMATICALLY REGISTERS STREAMBORNE TRACER CONCENTRATIONS AS A FUNCTION OF TIME ON A GELATIN-COATED FILM. THE FILM IS ROUTED THROUGH A DEVICE WHICH PASSES A CONTINUOUS SAMPLE-ALIQUOT DIVERTED FROM THE TRACER-DOSED STREAM OVER A SMALL SEGMENT OF THE FILM. THE EXPOSED FILM IS GATHERED PERIODICALLY FROM STREAMSITES AND ANALYZED IN A LABORATORY-BASED FLUOROMETER. USE OF THE SYSTEM IS STUDIED FOR GAGING STREAMFLOW TO: (1) PRODUCE A HYDROGRAPH, (2) MEASURE STREAM DISCHARGE INSTANTANEOUSLY, AND (3) DETERMINE TIME-OF-STREAM-TRAVEL. HYDROGRAPHS RESULTING FROM 640 HR OF GAGING 2 COLORADO MOUNTAIN STREAMS WITH THE SYSTEM ARE COMPARED TO THOSE OBTAINED FROM CLOSELY LOCATED SHARP-CRESTED WEIRS. THE MAXIMUM INSTANTANEOUS DEVIATION BETWEEN HYDROGRAPHS REACHES 10%, THE AVERAGE ABSOLUTE DEPARTURE EQUALS 1.8%, AND THE ALGEBRAIC DEPARTURE AVERAGES PLUS 0.3%. THE SYSTEM CAN BE USED WHEN AN EXPENSIVE, TEMPERATURE-SENSITIVE FLUOROMETER CANNOT BE STATIONED STREAMSIDE, AND WHEN THE PARTICULAR OBJECTIVES OF STREAM MEASUREMENTS DO NOT JUSTIFY THE COST OF CONVENTIONAL TECHNIQUES, BUT FAIR ACCURACY AND CONTINUOUS RECORDS OF SHORT TO MODERATE DURATION ARE DESIRED.

THIS PROBLEM WAS FIRST INVESTIGATED DURING THE INITIAL FILLING OF LAKE MEAD BY MAKING SEISMIC RECORDINGS AT 3 LOCATIONS NEAR THIS LAKE. DATA OBTAINED FROM THESE RECORDINGS INDICATED THAT CRUSTAL LOADINGS PRODUCED BY THE RESERVOIR DID NOT CAUSE AN INCREASE IN LOCAL EARTHQUAKES. A SIMILAR STUDY WAS MADE DURING THE FILLING OF SAN LUIS RESERVOIR, A 2,100,000-ACRE-FT BODY OF WATER LOCATED NEAR LOS BANOS, CALIF. THE RESERVOIR IS IN AN AREA WHICH HAS BEEN SUBJECTED TO INTENSE ACTIVITY. A PORTION OF THE ORTIGALITA FAULT EXTENDS BENEATH THE LAKE AREA, AND THE SAN ANDREAS FAULT PASSES WITHIN 22 MI OF THIS LOCATION. DATA OBTAINED DURING THE SAN LUIS SEISMIC INVESTIGATION ALSO FURNISH LITTLE OR NO INDICATION THAT RESERVOIR LOADINGS ON THE EARTH'S CRUST CAUSE AN INCREASE IN LOCAL EARTHQUAKES.

DESPITE THE DIVERSITY OF DIMENSIONS AND THE VARIETY OF ROCK ENCOUNTERED DURING EXCAVATION, THE 6 TUNNELS HAVE ONE MAJOR CHARACTERISTIC IN COMMON: EXCAVATION WAS SIGNIFICANTLY EXPEDITED BY THE USE OF BORING MACHINES. BORING MACHINES MAKE POSSIBLE SMOOTHER WALLS AND UNIFORM DIAMETER, AND MORE IMPORTANTLY IN THE TUNNEL LINING, CONSIDERABLY LESS CONCRETE IS REQUIRED TO MAINTAIN THE SPECIFIED UNIFORM THICKNESS THAN IS REQUIRED FOR THE ROUGH, IRREGULAR WALLS OF A CONVENTIONALLY DRIVEN TUNNEL. ONE EXAMPLE CITED WAS ESTIMATED TO REQUIRE 3-1/2 TIMES MORE CONCRETE FOR LINING A CONVENTIONALLY EXCAVATED TUNNEL THAN WAS USED FOR LINING THE BORED TUNNEL.

THE INVESTIGATION DETERMINED COSTS AND BENEFITS ASSOCIATED WITH DESALTING SALINE WATER AT CONCENTRATIONS OF 1500, 900, 400, 200 AND 50 PPM. BENEFITS FROM DESALTING ARE GENERATED BY SHIFTS TO MORE PROFITABLE CROPS, REDUCED COSTS FOR DRAINAGE, AND REDUCED FERTILIZER AND LABOR REQUIREMENTS WITH BETTER QUALITY WATER. COSTS ARE BASED ON PROJECT FEATURES SUCH AS DESALTING PLANTS, RAW WATER DIVERSION FACILITIES, STORAGE RESERVOIRS, CONVEYANCE AND DISTRIBUTION SYSTEMS, BRINE DISPOSAL, BLENDING FACILITIES, AND GYPSUM ADDITION SYSTEMS. HYDROLOGIC STUDIES DETERMINED CROP IRRIGATION REQUIREMENTS, WATER DEMAND SCHEDULES, DESALTED WATER STORAGE REQUIREMENTS, BRINE DISPOSAL REQUIREMENTS, AND SIZE OF FACILITIES REQUIRED. RECONNAISSANCE DESIGN LAYOUTS WERE MADE FOR PRODUCING DESALTED WATER USING A COMBINATION OF 14 SCHEMES. BENEFIT-COST RATIOS RANGE FROM 0.4 TO 1.0 FOR 1500 PPM IRRIGATION WATER TO 0.8 TO 1.0 FOR 50 AND 200 PPM WATER. INVESTMENT COSTS PER ACRE ARE HIGH, RANGING FROM $12,900 TO $20,900. IRRIGATION BENEFITS ARE BASED ON THE INCREASE IN PRODUCTION FROM A DESERT CONDITION WITH NO WATER SUPPLY TO THE IRRIGATION CONDITIONS STUDIED.

OF MAJOR CONCERN WERE NOISE LEVELS IN THE RESIDENTIAL AREAS PRODUCED BY THE TRANSFORMERS, EXPOSURE OF O AND M PERSONNEL TO HIGH NOISE LEVELS INSIDE THE POWERPLANT, AND EXPOSURE OF VISITORS TO HIGH NOISE LEVELS IN THE TURBINE PITS AND ON A CROSSOVER BRIDGE ABOVE THE TRANSFORMERS. PROCEDURES, EQUIPMENT, NOISE LEVEL MEASUREMENTS MADE, AND METHOD OF ANALYSIS USED TO STUDY THE PROBLEM ARE PRESENTED. CONCLUSIONS ARE: (1) LOWERING THE TRANSFORMER NOISE LEVEL SPECIFICATION FROM 89 TO 80 DBA, COUPLED WITH THE BARRIER EFFECT OF THE POWERPLANT SUPERSTRUCTURE AND NORMAL ATTENUATION WITH DISTANCE WILL PREVENT ANY APPRECIABLE RISE OF NOISE LEVEL IN THE RESIDENTIAL AREAS; (2) SINCE THE THIRD POWERPLANT WILL BE OPERATED REMOTELY, O AND M PERSONNEL WILL SPEND ONLY SHORT PERIODS OF TIME IN THE NOISIER PARTS OF THE PLANT, AND HEARING PROTECTORS CAN BE USED MOST EFFECTIVELY; (3) REDUCED TRANSFORMER NOISE LEVELS, COUPLED WITH THE BARRIER EFFECT OF THE BRIDGE STRUCTURE, WILL RESULT IN ACCEPTABLE NOISE LEVELS ON THE CROSSOVER BRIDGE; AND (4) NOISE BARRIERS ARE NECESSARY IN THE TURBINE PITS TO PROTECT VISITORS FROM DISCOMFORT AND DIFFICULTY IN CONVERSING.

FROM 1905 TO 1951 PIEZOMETRIC GROUNDWATER LEVELS ALONG THE ALIGNMENT DECLINED UP TO 200 FEET. CANAL DELIVERIES STOPPED THE OVERDRAFT, BUT CONTINUING READJUSTMENT OF PORE PRESSURES CAUSED SOME 'RESIDUAL SUBSIDENCE' TO CONTINUE AT GRADUALLY DIMINISHING RATES. THE SUBSIDENCE HAS AFFECTED THE DOWNSTREAM 35-40 MILES OF THE CANAL, LOCALLY EXCEEDING 6 FEET FROM 1953 TO 1966. ESTIMATES OF ULTIMATE FUTURE SUBSIDENCE, VARYING FROM TRACES TO 3.6 FEET, WERE DERIVED FROM BENCH MARK DATA TREATED AS AN EXPONENTIAL DECAY FUNCTION. ABOUT 80 MILES OF THE SAN LUIS CANAL, CONSTRUCTED IN 1963-67, ARE SUBSIDING DUE TO GROUNDWATER OVERDRAFT. FROM 1905 TO 1962, PIEZOMETRIC LEVELS ALONG THE ALIGNMENT DECLINED UP TO 470 FEET, CAUSING UP TO 18 FEET OF SUBSIDENCE. HYDROCOMPACTION OF LOW-DENSITY SEDIMENTS ABOVE THE WATER TABLE OCCURS IN TWO PORTIONS OF THE SAN LUIS CANAL. THE PHENOMENA MAY BE RELATED TO FREEZING SWELLING AND FOLLOWING FREEZE-DRYING OF PLEISTOCENE MUDFLOWS. ULTIMATE AMOUNTS OF HYDROCOMPACTION RANGING FROM TRACES TO 20 FEET WERE CALCULATED FROM AVERAGE DRY DENSITIES OF SEDIMENTS AND 'ULTIMATE' DENSITY VALUES OBTAINED IN A FEW LONG-FLOODED AREAS.

THEY ARE THE COACHELLA VALLEY DISTRIBUTION SYSTEM IN SOUTHERN CALIFORNIA AND THE CANADIAN RIVER PROJECT IN NORTHWESTERN TEXAS. OPERATIONAL PROBLEMS IN THE 2 SYSTEMS, LABORATORY AND FIELD TESTS CONDUCTED BEFORE AND AFTER CONSTRUCTION, AND SOLUTIONS ADOPTED FOR SURGE AND AIR ENTRAINMENT PROBLEMS DURING DESIGN AND CONSTRUCTION ARE REVIEWED. PROBLEMS IN UPSTREAM CONTROL SYSTEMS HAVE BEEN MORE SEVERE THAN IN DOWNSTREAM CONTROL SYSTEMS. AN UPSTREAM CONTROL SYSTEM IS FEASIBLE FOR ECONOMICAL REASONS WHERE THE TOPOGRAPHY LENDS ITSELF TO SUCH A SYSTEM. PAST EXPERIENCE AND BETTER TOOLS FOR ANALYSIS WILL REDUCE THE MAGNITUDE OF FUTURE PROBLEMS IN UPSTREAM CONTROL SYSTEMS. FUTURE SYSTEMS ARE DISCUSSED, INCLUDING METHODS OF ANALYSIS FOR SURGING AND AIR ENTRAINMENT, AND TYPES OF STRUCUTRES THAT MAY BE USED.

THE U. S. BUREAU OF RECLAMATION'S WATER QUALITY SURVEILLANCE PROGRAM IN THE SAN FRANCISCO BAY-DELTA ESTUARY IS AN EXCELLENT EXAMPLE OF A COOPERATIVE STUDY. THE DELTA PLAYS A KEY ROLE IN THE BUREAU'S CENTRAL VALLEY PROJECT AND IN CALIFORNIA'S STATE WATER PROJECT, AS IT SERVES AS THE COLLECTION AND EXPORT POINT FOR WATER STORED IN RESERVVOIRS IN NORTHERN CALIFORNIA. WATER IS RELEASED FROM STORAGE AND IS PUMPED FROM THE DELTA CHANNELS TO BE SENT VIA CANALS TO AGRICULTURAL LANDS IN THE SEMIARID SAN JOAQUIN VALLEY. DATA COLLECTION FOR THE PROGRAM IS CARRIED OUT UNDER THE SUPERVISION OF THE BUREAU CORRELATIONS OF RESULTS USING DIFFERENT METHODS OF ANALYSIS ARE MADE SO THAT THE RESULTS CAN BE PLACED ON A COMMON BASIS.

FIELD TESTS WERE PERFORMED IN THE SUMMERS OF 1965, 1966, AND 1967. IODINE-131 AS NAI WAS APPLIED IN THE MEASUREMENT OF GROUND-WATER VELOCITY USING THE SINGLE DRILL HOLE METHOD. VELOCITY MEASUREMENTS WERE MADE WHEN THE RESERVOIR WAS DRY, AND RESULTS WERE COMPARED TO THOSE OBTAINED WHEN WATER WAS IMPOUNDED BEHIND THE DAM. TRITIATED WATER WAS ADDED TO THE RESERVOIR LEAKAGE, AND WATER SAMPLES WERE OBTAINED FROM DRILL HOLES LOCATED NEAR THE RESERVOIR FOR ANALYSIS OF TRITIUM CONTENT. RESERVOIR LEAKAGE IS THROUGH A SYSTEM OF UNDERGROUND CAVERNS WHICH HAVE OPENED TO THE SURFACE PREDOMINANTLY AT A FEW DISCRETE AREAS ON THE NORTH AND NORTHEAST SIDES OF THE RESERVOIR. GROUND-WATER DISSOLVED OXYGEN CONTENT, TRITIUM TRACER EXPERIMENTS, AND GROUND-WATER LEVEL SHOWED THAT THE WATER CASCADES INTO A CAVERNOUS SYSTEM AND IS CARRIED FROM THE RESERVOIR AREA IN A MAJOR ESCAPE ROUTE, WITH A RELATIVELY SMALL AMOUNT BEING ADDED INDIRECTLY TO THE NORMAL GROUND-WATER SYSTEM.

THE WATER RESOURCES OF THE BASIN MAY BE OVERCOMMITTED UNDER THE PRESENT FORM OF USAGE. DROUGHT DURING THE LATE 1940'S AND THE 1950'S CAUSED DISASTROUS REDUCTIONS IN STREAMFLOW. WATER DELIVERED TO NEW MEXICO AND TEXAS DECLINED MUCH MORE THAN DID THE ANNUAL RAINFALL OVER THE RIO GRANDE BASIN IN COLORADO OR THE STREAMFLOW UPSTREAM OF AREAS OF SIGNIFICANT DIVERSIONS AND USE. PART OF THE CLINE IN SURFACE WATER PRODUCTION MAY BE ATTRIBUTABLE TO SMALL CONSERVATION TANKS AND OTHER WATER-RETARDING DEVELOPMENTS. THE LOSS OF WATER IN THE MIDDLE SECTION TO NONBENEFICIAL EVAPOTRANSPIRATION IS ESTIMATED AT OVER ONE-HALF MILLION ACRE-FEET. DELIVERIES UNDER THE RIO GRANDE COMPACT HAVE NOT CLOSELY REFLECTED CLIMATOLOGICAL OR HYDROLOGICAL CONDITIONS. THE ECONOMIC EFFECTS CAUSED BY THE REDUCTION OF WATER IN THE LOWER REACHES OF THE BASIN HAVE BEEN VERY SEVERE. THE PRINCIPAL CAUSE SEEMS TO BE STREAM DEPLETIONS IN COLORADO.

MOST CRACKING IN MASS CONCRETE OCCURS BECAUSE OF STRESSES CAUSED BY RESTRAINT AGAINST VOLUMETRIC CHANGES INCLUDING TEMPERATURE CHANGE, DRYING SHRINKAGE, AND AUTOGENOUS SHRINKAGE. PRIMARY CONTROL METHODS ARE MIX DESIGN, TEMPERATURE CONTROL, AND USE OF CONTRACTION, EXPANSION, AND CONSTRUCTION JOINTS. BECAUSE OF THE HEAT GENERATED BY HYDRATION OF THE CEMENT, THE CONCRETE MIX SELECTED ONE SHOULD PROVIDE THE REQUIRED STRENGTH AND DURABILITY WITH THE LOWEST CEMENT CONTENT. EXPANSION AND CONTRACTION JOINTS ARE USED TO ACCOMMODATE VOLUMETRIC CHANGES. CONSTRUCTION JOINTS ARE USED TO FACILITATE CONSTRUCTION AND TO REDUCE CRACKING TENDENCIES. TEMPERATURE CONTROL MEASURES USED ARE PRECOOLING CONCRETE INGREDIENTS, POSTCOOLING BY MEANS OF EMBEDDED PIPE SYSTEMS, AND RESTRICTING THE TIME OR SEASON OF CONCRETE PLACEMENT. PRESSURE INJECTION OF PORTLAND CEMENT GROUT IS THE MOST ECONOMICAL METHOD OF REPAIRING CRACKS. EPOXY GROUTS STOP LEAKS AND CAN RESTORE THE STRUCTURAL STRENGTH OF CONCRETE, BUT CRACKS MUST BE DRY FOR EFFECTIVE BONDING. CHEMICAL GROUTS HAVE BEEN USED TO SEAL SMALL CRACKS. (USBR) JF - INT. COMM.

FOUR VIEWPOINTS EXAMINING THIS POSSIBILITY ARE: (1) FEDERAL STUDIES, (2) THE MISSISSIPPI RIVER COMMISSION STUDIES, (3) THE STATE OF LOUISIANA DEPARTMENT OF PUBLIC WORKS STUDIES, AND (4) THE STATE OF TEXAS WATER DEVELOPMENT BOARD STUDIES. NO WATER PROJECT IN HISTORY REMOTELY APPROACHES THE SIZE OF THE IMPORT PROJECT NEEDED TO MAINTAIN THE ECONOMY OF THE TEXAS-NEW MEXICO AREA. THE PROJECT CANNOT BE PLANNED AND DEVELOPED SOLELY AS A WATER SUPPLY FOR WESTERN TEXAS AND EASTERN NEW MEXICO. THERE IS NO ASSURANCE THAT A SINGLE DROP OF MISSISSIPPI RIVER WATER WILL EVER BE AVAILABLE FOR EXPORT. SUCH ASSURANCE WOULD REQUIRE THE CONCURRENCE AND SUPPORT OF THE STATES THAT DEPEND ON THE LOWER MISSISSIPPI RIVER SYSTEM TO SUSTAIN MAJOR SECTIONS OF THEIR ECONOMIES.

THE TESTS, CONDUCTED DURING 1969, WERE ON 363 ACRES NEAR MCCOOK, NEBRASKA AND 260 ACRES NEAR TORRINGTON, WYOMING. THE PRINCIPAL CROPS IN THE TEST AREAS WERE: CORN, SUGARBEETS, BEANS, ALFALFA AND SMALL GRAINS. DUE TO DISEASES THE PREVIOUS YEAR DIRECT CORRELATION OF YIELDS WAS IMPOSSIBLE. HOWEVER, A SIGNIFICANT INCREASE WAS SHOWN. THE COST OF THE SERVICES, ON A COMMERCIAL BASIS, IS ESTIMATED AT BETWEEN $1.50 AND $4.00 PER ACRE PER YEAR, DEPENDING ON HOW MUCH OF THE DATA IS COLLECTED BY THE FARMER. WATER SAVINGS OF FROM 10 TO 15 PERCENT WERE OBSERVED. OTHER BENEFITS ARE: REDUCED LABOR COSTS, REDUCED FERTILIZER REQUIREMENTS, INCREASED NET RETURNS, AND FEWER DRAINAGE PROBLEMS.

THE PURPOSE WAS TO DETERMINE ANY BENEFICIAL EFFECTS ON THE PROPERTIES OF SOIL-CEMENT AS USED IN BUREAU OF RECLAMATION CONSTRUCTION. BY THE PREFORMED METHOD, SOME SPECIMENS WERE IMPREGNATED WITH MMA AND POLYMERIZATION WAS BY GAMMA RADIATION FROM COBALT 60. OTHER SPECIMENS BY THE PREMIX METHOD HAD 3% OR 6% MMA WITH 1% BENZOIL PEROXIDE AS A CATALYST INCORPORATED DURING SPECIMEN PREPARATION; POLYMERIZATION WAS BY HEAT. THE COMPRESSIVE STRENGTH OF THE PREFORMED SPECIMENS CONTAINING SILTY SAND WAS INCREASED ABOUT 3.4 TIMES THAT OF SPECIMENS WITHOUT MMA, BUT THE PREMIX SPECIMENS DID NOT INCREASE IN STRENGTH. RESULTS OF FREEZE-THAW TESTS DID NOT SHOW CONCLUSIVE TRENDS, BUT THERE WERE INDICATIONS OF IMPROVEMENT WITH THE ADDITION OF MMA. THE MMA REDUCED SIGNIFICANTLY THE PERMEABILITY OF THE SILTY SAND SPECIMENS. PETROGRAPHIC EXAMINATIONS SHOWED THAT THE MMA PENETRATION AND FILLED THE VOIDS OF PORTIONS OF THE SILTY SAND SPECIMENS, BUT THE VOIDS IN THE SILT SPECIMENS WERE NEARLY EMPTY.

THESE ISLANDS PROVIDE AN EXCELLENT OPPORTUNITY TO STUDY THE ECOLOGY AND PHYSIOGRAPHY OF BARRIER ISLANDS STILL IN THEIR NATURAL STATE. MAN IS THE BARRIER ISLAND'S WORST ENEMY, NOT THE SEA. BARRIER ISLANDS HAVE AN INTRINSIC MECHANISM FOR SURVIVING ENORMOUS OCEANIC FORCES. MAN'S INTERFERENCE WITH THIS MECHANISM WITH THE THOUGHT HE IS IMPROVING OR RESTORING THE 'NATURAL ECOLOGY' MAY, IN FACT, LEAD TO THE VERY BREAKDOWN HE IS TRYING TO PREVENT. THE VEGETATION THAT SURVIVES ON LOW BARRIER ISLANDS IS WELL ADAPTED TO CONDITIONS OF OVERWASH (THE PROCESS WHEREBY STORM-DRIVEN SEA WATER COMPLETELY INUNDATES THE BARRIER ISLANDS AND SAND MOVES FROM THE BEACH FACE TOWARD THE BACK OF THE ISLAND. CONTRARY TO GENERALLY ACCEPTED INTERPRETATIONS, THIS PROCESS IS NOT DESTRUCTIVE, BUT CONSTITUTIVE, IF UNDISTURBED BY MAN. IT IS THE MEANS BY WHICH THE OCEAN BUILDS AND MOVES THE BARRIER ISLANDS, AND THIS MOVEMENT IS ESSENTIAL FOR THEIR CONTINUED SURVIVAL. (WOODARD-USGS) JF - APRIL 8, 1970. 37 P, 14 FIG, 22 REF.

STORAGE SYSTEM LOSSES, CONVEYANCE SYSTEM LOSSES, EVAPORATION FROM WATER SURFACES, CONSUMPTIVE USE OF NONCROP PLANTS, SURFACE RUNOFF, DEEP PERCOLATION LOSSES, AND LEACHING WATER REQUIREMENTS ARE OTHER COMPONENTS OF THE TOTAL IRRIGATION DIVERSION REQUIREMENT. TWO NEAR-TERM POSSIBILITIES EXIST FOR IRRIGATORS TO SAVE WATER. FIRST, INCREASE THE EFFICIENCY OF IRRIGATION SYSTEMS, AND SECOND, DEVELOP MEANS FOR ACHIEVING MORE EFFICIENT USE OF WATER ON THE FARM. IRRIGATION EFFICIENCY CAN BE INCREASED BY ADVANCED SYSTEM DESIGN, AND WATER USE CAN BE MADE MORE EFFICIENT BY ADOPTING PRACTICAL METHODS OF IRRIGATION SCHEDULING AND AUTOMATION OF FARM IRRIGATION SYSTEMS. THESE CHANGES NEED TO BE COUPLED TO ADVANCES IN KNOWLEDGE CONCERNING EVAPOTRANSPIRATION.

THE METHOD IS BASED ON MEASURING THE DIAMETRICAL CHANGE IN A BOREHOLE CAUSED BY OVERCORING WITH A LARGER-DIAMETER BIT, AND INDICATES THAT MEASUREMENTS IN 2 NONPARALLEL, NONPERPENDICULAR DRILL HOLES ARE SUFFICIENT TO DETERMINE ALL 6 COMPONENTS OF 3-DIMENSIONAL STRESS. NECESSARY EQUIPMENT WAS FABRICATED, CALCULATIONS FOR THE 2-DRILL HOLE APPROACH WERE PROGRAMED FOR COMPUTER ANALYSIS, AND STRESS RELIEF TESTS WERE PERFORMED ON 3 BIAXIALLY LOADED CONCRETE BLOCKS. TEST RESULTS WERE ANALYZED, BUT SOLUTIONS WERE UNOBTAINABLE. FURTHER STUDY INDICATED THAT 3 DRILL HOLES ARE REQUIRED TO OBTAIN SOLUTIONS. A COMPUTER PROGRAM WAS PREPARED FOR DETERMINING STRESSES FOR 3 OR MORE DRILL HOLES, ADDITIONAL STRESS RELIEF TESTS WERE PERFORMED USING 3 DRILL HOLES, AND SATISFACTORY SOLUTIONS WERE OBTAINED. CONCLUSIONS ARE: (1) 3 NONPARALLEL DRILL HOLES ARE REQUIRED TO OBTAIN A 3-DIMENSIONAL STRESS SOLUTION; (2) THE STRESS-RELIEF METHOD USING THE BOREHOLE GAGE REQUIRES COMPLEX AND PRECISE PROCEDURES; AND (3) THE METHOD IS SUITABLE FOR OBTAINING STRESSES IN LARGE MASSES.

OVERIRRIGATION MAY RESULT IN WATERLOGGED SOILS, A CONDITION WHICH REDUCES YIELDS AND GENERALLY RESULTS IN INCREASED COSTS FOR WATER, FERTILIZER, AND DRAINAGE. WATER USE IS AT A MINIMUM WHEN THE AMOUNT OF WATER APPLIED IS JUST EQUAL TO THE CONSUMPTIVE USE AND THE LEACHING REQUIREMENT. TO ACHIEVE HIGHER IRRIGATION EFFICIENCIES, PRESENT IRRIGATION SCHEDULING PRACTICES MUST BE IMPROVED. IRRIGATION SCHEDULING USING CLIMATE-CROP-SOIL DATA, COMPUTERS TO FACILITATE THE TEDIOUS COMPUTATIONS, AND FIELD OBSERVATIONS BY EXPERIENCED PERSONNEL IS A SERVICE THAT APPEARS TO BE VERY ATTRACTIVE TO THE MODERN IRRIGATION FARM MANAGER. THIS SERVICE HAS THE POTENTIAL OF INCREASING THE MANAGEMENT SKILLS OF THE FARMER AND HIS NET RETURN AT A REASONABLE COST. IT SUPPLEMENTS THE ART OF IRRIGATION OR EXPERIENCED JUDGEMENT WITH THE RESULTS OF RECENT ADVANCES IN IRRIGATION SCIENCE.

THE DITCHBANKS ALONG THESE CANALS RECEIVED ROUTINE APPLICATIONS OF 2,4-D FOR CONTROL OF WEEDS. MAXIMUM CONCENTRATION OF 2,4-D FOUND IN EACH CANAL RANGED AS FOLLOWS: 6 TO 28 PPB IN 9 CANALS, 38 TO 100 PPB IN 8 CANALS, AND 214 PPB IN ONE CANAL. IN THE 9 CANALS HAVING THE VERY LOW CONCENTRATIONS, THE DECLINE OF THE PEAK LEVEL OF 2,4-D WAS VERY GRADUAL AS THE WATER MOVED DOWNSTREAM. THE PEAK LEVELS IN THE CANALS WITH THE HIGHER CONCENTRATIONS SHOWED SOME RISES AND DECLINES AT SAMPLING STATIONS BELOW THE FIRST SAMPLING SITE. THIS STUDY INDICATES THAT THE DIMETHYLAMINE FORMULATION OF 2,4-D IS PERSISTENT FOR SEVERAL MILES IN IRRIGATION WATER WITHOUT MUCH DECLINE IN CONCENTRATION. IN MOST CASES, THOSE CANALS CARRYING THE GREATER QUANTITY OF WATER (74 TO 840 CFS) CONTAINED THE LOWEST LEVELS OF 2,4-D, AND THE HIGHER LEVELS OCCURRED IN FLOWS RANGING FROM 6.8 TO 56 CFS. WATERFLOW, APPLICATION RATE, AND HERBICIDE SPRAY OVERLAP ONTO THE WATER SURFACE ARE MAJOR FACTORS INFLUENCING HERBICIDE CONCENTRATION IN IRRIGATION WATER.

Each employs the individual as the basic unit of analysis. It is suggested that work & 'not-work' differ in a systematic manner in terms of the basic unit of analysis appropriate for study, the distribution of social approval, characteristic emotional states experienced by participants, & the age classes of appropriate participants. Social institutions are ordered in terms of these 2 principles of social organization. Implications for the study of leisure are examined.

THIS SPECIAL AND LIMITED FORM OF ECONOMIC ANALYSIS HAS BECOME SO STANDARDIZED IN BENEFIT-COST STUDIES OF FEDERAL RESOURCE INVESTMENT ALTERNATIVES (ESPECIALLY IN THE AREA OF WATER DEVELOPMENT) AS TO VIRTUALLY RULE OUT OTHER, AND MORE USEFUL, FORMS OF ANALYSIS. THE AUTHORS ARGUE THAT INFORMATION CONTAINED IN CONVENTIONAL BENEFIT-COST ANALYSIS DOES NOT DISPEL THE UNCERTAINTY REGARDING THE CONSEQUENCES OF ALTERNATIVE LINES OF ACTION, IS SOMETIMES MISLEADING, AND TENDS TO INHIBIT THE SEARCH FOR ACCEPTABLE ALTERNATIVES. THE ARGUMENT IS BASED ON THE AUTHOR'S EXPERIENCE IN HELPING TO DESIGN, TEST AND IMPLEMENT A COMPREHENSIVE PLANNING SYSTEM FOR USE BY THE U.S. DEPARTMENT OF THE INTERIOR'S BUREAU OF LAND MANAGEMENT (BLM) AND IS SUPPORTED BY EXAMPLES DRAWN FROM THIS EXPERIENCE. AMONG THE SUBJECTS DISCUSSED ARE: THE NATURE AND SCOPE OF BLM ACTIVITIES, PLANNING AS A MANAGEMENT TOOL, ECONOMIC EFFICIENCY AS A GUIDE TO PLANNING, INCIDENCE RATHER THAN EFFICIENCY. THE AUTHORS CONCLUDE THAT IF THE ECONOMIST IS TO BE MORE USEFUL IN THE PLANNING PROCESS, HE WILL HAVE TO DETERMINE WHAT PEOPLE WANT AND HOW THEY GO ABOUT SATISFYING THESE WANTS. THE ECONOMIST WILL HAVE TO ABANDON EXCLUSIVE RELIANCE ON AN ANALYTICAL TOOL DESIGNED TO GUIDE PRIVATE MANAGERIAL DECISIONS, AND INSTEAD, DEVELOP TOOLS CAPABLE OF GUIDING PUBLIC DECISIONS AIMED AT ACHIEVING MULTIPLE OBJECTIVES. FURTHER, HE MUST REMEMBER THAT THE SEARCH FOR ACCEPTABLE ALTERNATIVES IS A POLITICAL BARGAINING PROCESS.

A FEATURE NEW TO BUREAU OF RECLAMATION DESIGN IS A PAD OF CONCRETE TO BE PLACED AS AN INTEGRAL PART OF THE DAM THROUGHOUT THE PROFILE OF THE DAMSITE BETWEEN THE ARCH AND ABUTMENT ROCK. THE PAD WILL IMPROVE THE SYMMETRY OF THE ARCHES AND REDUCE THE LOAD INTENSITY BETWEEN THE ARCH SECTION AND ABUTMENTS BY DISTRIBUTING THE PRESSURE MORE UNIFORMLY ON THE FOUNDATION. EXTENSIVE FOUNDATION INVESTIGATIONS AND TESTS WERE MADE BECAUSE OF THE SIZE OF THE DAM AND THE COMPLEXITY OF THE GEOLOGICAL FORMATION AT THE DAMSITE.

THE WESTERNMOST THREE ARE IN YELLOWSTONE NATIONAL PARK. ALL ARE ASSOCIATED WITH ABUNDANT SULFUR AND THERMAL SPRINGS AND VENTS. FOUR ARE SURROUNDED AND UNDERLAIN BY VOLCANIC ROCKS, WHICH RANGE IN AGE FROM EOCENE TO PLEISTOCENE. THE FIFTH EMERGES FROM PALEOZOIC STRATA. THE SOURCE OF THE HYDROCARBONS COULD BE PALEOZOIC OR MESOZOIC SEDIMENTARY ROCKS THAT UNDERLIE THE SURFICIAL VOLCANICS, BUT AT RAINBOW SPRINGS THE OIL MIGHT HAVE BEEN DISTILLED FROM PLEISTOCENE NONMARINE ALGAE AT SHALLOW DEPTH. SULFUR ISOTOPE ANALYSES DO NOT INDICATE CONCLUSIVELY WHETHER THE SULFUR IS OF IGNEOUS OR BACTERIOGENIC ORIGIN. IN AT LEAST TWO OF THE LOCALITIES, HOT WATER AND STEAM THAT DERIVE THEIR HEAT FROM AN IGNEOUS SOURCE BELOW THE SEDIMENTS ARE BELIEVED TO RELATE DIRECTLY TO THE EXTRACTION OF THE HYDROCARBONS, TRANSPORT UPWARD ALONG CONDUITS, AND EXTRUSION ON THE SURFACE.

A CIRCULAR CURVE IN AN INCLINED PLANE WAS USED TO CONNECT THE UNDAMAGED APPROACH CONDUIT AND THE RELOCATED STILLING BASIN. HYDRAULIC MODEL STUDIES WERE PERFORMED TO ASSURE SATISFACTORY FLOW CONDITIONS IN THE CONDUIT AND STILLING BASIN UNDER LIMITED TAILWATER CONDITIONS AND WITH UNSYMETRICAL APPROACH FLOW RESULTING FROM A CIRCULAR CURVE IN THE UPSTREAM CONDUIT. A DEFLECTOR VANE WAS INSTALLED IN THE CROWN OF THE TUNNEL DOWNSTREAM FROM THE CURVE TO PREVENT THE FLOW FROM CROSSING OVER THE TOP AND SEALING THE PORTAL. VANES WERE DEVELOPED FOR THE STILLING BASIN APPROACH CHUTE TO IMPROVE FLOW DISTRIBUTION IN THE BASIN. UNIQUE DAFFLE BLOCKS WERE DEVELOPED TO PROVIDE GOOD ENERGY DISTRIBUTION IN A BASIN THAT HAD INSUFFICIENT TAILWATER DEPTH TO FORM A CONVENTIONAL HYDRAULIC JUMP.

THE PRESENT STATUS IN THE FIELD CAN BE DESCRIBED AS EXTREMELY ENCOURAGING WHEN ATTENTION IS GIVEN TO SINGLE CLOUD EXPERIMENTS OR LIMITED AREA SEEDING IN WINTER STORMS. A NUMBER OF CLOUD-SEEDING TECHNIQUES HAVE BEEN DEVELOPED. GROUND-BASED SEEDING, USING SILVER IODIDE GENERATORS, IS THE MOST COMMONLY USED TECHNIQUE, ESPECIALLY FOR WINTER STORMS IN MOUNTAINOUS TERRAIN. AIRBORNE SEEDING, USING SILVER IODIDE OR CRUSHED DRY ICE, IS FREQUENTLY EMPLOYED WITH SUMMER CONVECTIVE STORMS. CAREFUL ATTENTION MUST BE GIVEN TO MATCHING THE TECHNIQUES (OR TOOLS) NEEDED TO FORM A BALANCED SYSTEM TO ACCOMPLISH THE JOB. A TRUE PRECIPITATION MANAGEMENT SYSTEM SHOULD HAVE: (1) A COMPONENT TO ANALYZE THE PRESENT AND EXPECTED WATER NEEDS AND WATER SOURCES, PLUS THE ANTICIPATED EFFECTS OF PRECIPITATION MANAGEMENT; (2) A COMPONENT TO RECOGNIZE WEATHER IN WHICH PRECIPITATION MANAGEMENT WOULD RESULT IN THE DESIRED EFFECT (OR UNDESIRABLE EFFECTS); (3) A COMPONENT TO SELECT THE PROPER TREATMENT MATERIAL AND DELIVERY SYSTEM; AND (4) A COMPONENT TO ASSESS THE RESULTS.

LARGE- AND SMALL-SCALE STRUCTURAL QUALITIES OF ARCH DAMS AND ADAPT TO MORE DIFFICULT SITE CONDITIONS. LARGE- AND SMALL-SCALE STRUCTURAL MODELS ARE USED FOR ARCH DAM ANALYSIS; DEVELOPMENT OF ELECTRONIC COMPUTERS HAS MADE THE USE OF SEVERAL COMPLEX AND COMPREHENSIVE METHODS OF ANALYSIS FEASIBLE, INCLUDING THE TRIAL-LOAD, SHELL-THEORY, FINITE ELEMENT, AND DYNAMIC-RELATION METHODS. THE METHODS PERMIT RAPID, RELIABLE EVALUATION OF MANY ALTERNATIVE SOLUTIONS FOR EACH SITE, SUBJECTED TO ALL ANTICIPATED LOADING CONDITIONS. GOOD COMPARISONS BETWEEN COMPUTED AND MEASURED PROTOTYPE BEHAVIOR HAVE SUBSTANTIATED DESIGN ANALYSES. BETTER UNDERSTANDING OF FOUNDATION REQUIREMENTS AND ROCK MECHANICS HAS CONTRIBUTED GREATER SAFETY AND EFFICIENCY TO ARCH DAM DESIGN. COMPUTED SAFETY FACTORS OF 4 TO 1 ARE USUALLY REQUIRED FOR ARCH DAMS FOR NORMAL LOADING CONDTIONS, WITH A REDUCTION PERMITTED FOR UNUSUAL LOADING. IF DESIGN FEATURES PERMIT THEIR CONSIDERATION, ORIFICE OR OVERFLOW FREE-FALL SPILLWAYS MAY BE MORE ECONOMICAL THAN TUNNEL OR SIDE CHANNEL SPILLWAYS USUALLY DESIGNED FOR ARCH DAMS.

THE POWER PRODUCED IS A BONUS TO THE SYSTEMS. THE BUREAU OF RECLAMATION HAS 21 REVERSIBLE PUMP-TURBINE UNITS OPERATING IN 4 PLANTS. FOUR ADDITIONAL UNITS TO BE INSTALLED IN 2 PLANTS ARE IN THE DESIGN STAGE. THE 4 OPERATING PUMPED STORAGE PLANTS AND THE 2 PLANTS BEING DESIGNED ARE DISCUSSED. WHEN POWER SYSTEM EMERGENCIES OCCUR, RAPID REVERSAL FROM PUMPING TO GENERATING WITHIN A FEW SECONDS IS AN ASSET TO THE SYSTEM. PUMP-TURBINE DESIGN, OPERATION, AND MAINTENANCE CONSIDERATIONS ARE GIVEN. USE OF WICKET GATES OR DISCHARGE VALVES DEPENDS ON THE NEEDS OF INDIVIDUAL PLANT AND POWER SYSTEMS. BUREAU STARTUP PROBLEMS HAVE BEEN MINIMAL. EXPERIENCE SHOWS THAT MAJORATION BETWEEN MODEL AND PROTOTYPE CAN BE GREATER THAN THE MANUFACTURER ANTICIPATES.

THE MOVEMENT WAS ASSOCIATED WITH A LARGE ROCK POLYHEDRON FORMED IN PART BY 2 INTERSECTING FAULTS AND THE POWERPLANT ROCK WALL. INVESTIGATIONS INDICATED THAT FURTHER MOVEMENT WAS POSSIBLE, NECESSITATING INSTALLATION OF A PERMANENT RESTRAINT SYSTEM. GEOLOGY OF THE DAMSITE AND POWERPLANT AREA, PRECONSTRUCTION ROCK STABILITY ANALYSIS, INSTRUMENTATION, ROCK MOVEMENT, ANALYSIS TO EVALUATE ROCK MOVEMENT, AND MEASURES TO STOP THE MOVEMENT ARE DESCRIBED. ANCHOR BARS, LONG ROCK BOLTS, POSTSTRESSED TENDONS, AND FLAT JACKS WERE SELECTED TO PROVIDE THE REQUIRED SUPPORT. THE RESTRAINT SYSTEM, DESIGNED OUT OF NECESSITY BY INTUITIVE ENGINEERING JUDGEMENT, PROVED TO BE PROPERLY DESIGNED ON THE BASIS OF AN IMPROVED METHOD OF ROCK MECHANICS ANALYSIS.

THE PRINCIPAL CAUSE OF CONSTRUCTION ACCIDENTS HAS BEEN INABILITY TO COPE FULLY WITH THE HUMAN ELEMENT. A 4-YR STUDY OF ACCIDENT CAUSES THROUGHOUT THE DEPARTMENT OF THE INTERIOR SHOWS THAT 86% OF ALL ACCIDENTS INVOLVING USE OF CONSTRUCTION EQUIPMENT RESULTED FROM PERSONAL CAUSES. THE BASIC FAULT LIES WITH THE FAILURE OF MANAGEMENT AND LABOR TO PROVIDE EFFECTIVE SAFETY EDUCATION AND TRAINING. EXPERIENCE SHOWS THAT THE SAFETY TRAINING COURSE FOR CONSTRUCTION SUPERVISORS SPONSORED BY THE ASSOCIATED GENERAL CONTRACTORS OF AMERICA IS AN EFFECTIVE PROGRAM. BECAUSE OF THE LENGTH AND EXPENSE OF THE PROGRAM, IT IS REACHING ONLY A FEW HUNDRED PEOPLE A YEAR, WHEN TO BE TRULY EFFECTIVE IT SHOULD BE REACHING THOUSANDS. A PROGRAM (BASED ON THE AGC COURSE) PLANNED BY THE BUREAU OF RECLAMATION WITH THE AIM OF BEING MADE AVAILABLE TO ALL CONTRACTOR FOREMEN ON BUREAU JOBS IS OUTLINED.

THE VOLUMES EXTRACTED FROM THE PROBES AND COLLECTED IN THE LEACHATES WERE RECORDED. ALL OF THE SAMPLES WERE ANALYZED FOR CHLORIDES, AMMONIA, TOTAL NITROGEN AND ATOM PERCENT EXCESS N. THE NITRATE LEVELS IN LEACHATES COLLECTED DURING INITIAL LEACHING AND BEFORE FERTILIZATION RANGED FROM 20,000 PPM IN THE OXALIS CLAY TO 2,500 PPM IN THE PANOCHE FINE SANDY LOAM. THESE HIGH NITRATE LEVELS INDICATE HOW RELATIVELY LOW LEVELS OF NATIVE NITRATES CAN BE CONCENTRATED IN THE GROUNDWATER BY LEACHING. THE HIGHEST PERCENTAGE OF FERTILIZER -N WAS LEACHED FROM SOILS TO WHICH KNO3 WAS APPLIED. IN PANOCHE FINE SANDY LOAM AND LETHENT SANDY CLAY LOAM, RESPECTIVELY, 82 AND 65% OF THE TOTAL NITROGEN COLLECTED IN THE SOIL EXTRACT WAS FERTILIZER-N. BY COMPARISON, ONLY 14 TO 24% OF THE N IN THE EXTRACT WAS FERTILIZER -N WHEN AMMONIUM SULFATE AND SULFUR-COATED UREA WERE THE N SOURCES. MUCH OF THE ADDED NH4-N IS TIED UP BY THE CLAY COMPLEX OF THE SOIL NEAR THE SOIL SURFACE. SINCE ONLY 30% OF SULFUR-COATED UREA WAS READILY SOLUBLE AND THE REMAINDER WAS TREATED TO DISSOLVE SLOWLY, MOVEMENT OF NITROGEN AS UREA COULD BE EXPECTED TO BE APPROXIMATELY 30% OF N MOVEMENT FROM KNO3 ASSUMING APPRECIABLE HYDROLYSIS DID NOT OCCUR.

AIR IS ENTRAPPED IN CONCRETE CAPILLARIES DURING MOVEMENT OF WATER IN THE AGGREGATE CAPILLARIES FROM THE PERIPHERY TO THE CENTER OR DURING UNILATERAL CONTACT OF POROUS MATERIALS WITH WATER DUE TO NONUNIFORM WATER MOVEMENT IN CAPILLARIES OF DIFFERENT DIAMETERS. A PRESSURE GRADIENT DEPENDING ON THE DENSITY INCREASE IN THE CEMENT PASTE DEVELOPS IN THE CONTACT BETWEEN THE CEMENT PASTE AND THE AGGREGATE. THIS PHENOMENON EXPLAINS WHY LIGHTWEIGHT CONCRETE CAN HAVE GREATER COMPRESSIVE STRENGTH AND IMPERMEABILITY THAN ORDINARY CONCRETE MADE UNDER EXACTLY COMPARABLE CONDITIONS. PRESSURE OF ENTRAPPED AIR CAN SIGNIFICANTLY EXCEED 1 ATM. THIS PRESSURE IS DETERMINED BY COMPUTATIONS BASED ON EXPERIMENTAL DATA. APPARATUS AND METHODS USED TO MAKE THE NECESSARY MEASUREMENTS ARE DESCRIBED AND THEN THE COMPUTATIONS GIVEN TO CONVERT THEM TO VALUES FOR THE VOLUME AND PRESSURE OF ENTRAPPED AIR. THIS METHOD CAN ALSO BE USED TO DETERMINE THE ACTUAL TOTAL VOLUME OF INTERCONNECTED (OPEN) AND CLOSED PORES AND CAPILLARIES AND THE RATE OF WATER ABSORPTION FOR NEGATIVE AND ATMOSPHERIC PRESSURES.

UNTIL THE 1930'S USE OF THESE LANDS WAS A TRIAL AND ERROR ATTEMPT TO ADAPT INSTITUTIONS AND LAWS OF A HUMID LAND TO AN ARID LAND. IT DID NOT WORK. SUCCESSFUL LAND RECLAMATION FOR LARGE IRRIGATION PROJECTS REQUIRED VAST SUMS OF MONEY AND TECHNICAL KNOW-HOW GENERALLY AVAILABLE ONLY AT THE FEDERAL LEVEL. UNCONTROLLED USE OF NON-IRRIGATED LANDS FOR MINERAL EXPLORATION AND EXPLOITATION AND FOR GRAZING PUT SUCH PRESSURE ON THE FINE ECOLOGICAL BALANCE OF THE ARID LANDS THAT THEY BEGAN TO DETERIORATE. WHERE WATER WAS AVAILABLE FOR IRRIGATION, FEDERAL RECLAMATION PROGRAMS WERE DEVELOPED ON A LONG TERM PLANNING BASIS. IN 1934 THE TAYLOR ACT PLACED THE REMAINING LANDS, WHERE ONLY LIMITED MOISTURE OF AN ARID CLIMATE WAS AVAILABLE, UNDER FEDERAL CONTROLS WHICH CLOSED IT TO ALL BUT CAREFULLY PLANNED AND MANAGED USE. THE AUTHOR REVIEWS DEVELOPMENT OF LAND CLASSIFICATION SCHEMES AND PROGRAMS FOR LAND-USE DECISIONS - HOPEFULLY BASED ON KNOWLEDGE OF THEIR CONSEQUENCES. HE EMPHASIZES THAT OUR ARID LANDS ARE OUR LAST FRONTIER. THERE IS NO PLACE ELSE TO MOVE IN THE U.S. IF WE MAKE MISTAKES. IF THE ARID LANDS ARE MISMANAGED THEY COULD BECOME AN ECOLOGICAL DISASTER.

A GOVERNMENT-INDUSTRY COOPERATIVE STUDY OF RPM PIPE WAS INITIATED WITH THE OBJECTIVE OF GENERATING SUFFICIENT PERFORMANCE DATA AND KNOWLEDGE TO PERMIT PREPARATION OF BUREAU OF RECLAMATION SPECIFICATIONS FOR OBTAINING RELIABLE PIPE. LABORATORY TESTS WERE DESIGNED TO: (1) EVALUATE CHANGES IN PHYSICAL PROPERTIES AFTER ENVIRONMENTAL EXPOSURE, (2) DETERMINE IF PERFORMANCE OF LARGE-DIAMETER PIPE CAN BE CORRELATED TO PERFORMANCE OF SMALL-DIAMETER PIPE BY SCALING FACTORS, AND (3) RELATE STIFFNESS DATA FOR VARIOUS CLASSES OF RPM PIPE. TESTS WERE ALSO MADE TO DETERMINE DEFORMATION OF RPM PIPE BURIED IN COMPACTED SOIL AND UNDER EXTERNAL LOAD. FIELD STUDIES INCLUDED TESTS ON A 15-IN.-DIA PIPE IN A TEST SECTION IN THE WESTLANDS IRRIGATION DISTRICT, CALIF, AND A 39-IN.-DIA PIPE IN THE LOWER YELLOWSTONE IRRIGATION DISTRICT, MONT. RESULTS TO DATE SHOW THAT PERFORMANCE IS AS EXPECTED, AND IF PRESENT TRENDS CONTINUE, RPM PIPE EVENTUALLY MAY BE SPECIFIED AS AN ALTERNATE TO OTHER TYPES OF WATER PIPE. (USBR) JF - PAPER, AMER. SOC.

DESALINATION FOR IRRIGATION IS MOST FAVORABLE IN AREAS PRODUCING CROPS THAT YIELD HIGH NET FARM INCOMES UNDER YEARLONG GROWING SEASONS. IRRIGATION DEVELOPMENTS OF ABOUT 10,000 ACRES REQUIRE LARGE-SCALE MULTISTAGE FLASH DISTILLATION PLANTS UTILIZING NUCLEAR ENERGY, BUT ELECTRODIALYSIS IS MORE FAVORABLE FOR SMALLER IRRIGATED AREAS. THE SODIUM ADSORPTION RATIO AND BORON CONTENT OF PRODUCT WATER MUST BE REDUCED TO ASSURE SUSTAINED PRODUCTIVITY. BENEFIT-COST ANALYSIS INDICATES THAT 400 PPM (TDS) IS THE OPTIMUM PRODUCT WATER QUALITY. UNIT WATER COST WAS LEAST IN LARGER PLANTS.

AN EVALUATION OF THE ELECTRICAL, MECHANICAL, AND HYDRAULIC DUTIES ON THE UNITS AND THE ASSOCIATED EQUIPMENT SHOWED THAT NO ABNORMAL STRESS FOR THE PROPOSED RAPID REVERSAL EXISTED. EXTENSIVE CONTROL MODIFICATIONS WERE MADE ON ONE OF THE UNITS, PERMITTING A SERIES OF TESTS THAT HAVE VERIFIED THE FEASIBILITY OF THE RAPID REVERSAL MODE. REVERSALS FROM PUMPING TO GENERATING TAKE FROM 40 SEC AT LOW HEAD TO 27 SEC NEAR THE MAXIMUM HEAD. ONE MAJOR ADVANTAGE OF THIS RAPID REVERSAL WILL BE SYSTEM SUPPORT IN THE CASE OF DECAYING SYSTEM FREQUENCY. OTHER OPERATIONAL ADVANTAGES ARE ALSO SEEN. THE RAPID REVERSAL MODE MAY BE SUITABLE IN PART FOR MORE CONVENTIONAL PUMP-STORAGE INSTALLATIONS.

IN THE COURSE OF THEIR FEEDING, THESE ORGANISMS CONSTANTLY REMOVE SUSPENDED INORGANIC AND ORGANIC PARTICLES FROM WATER, COMBINE THEM WITH ORGANIC BINDER, AND DEPOSIT THEM AS EXCRETA. THE 'STICKY' EXCRETA (AND SHELLS) TRAP SAND AND OTHER PARTICLES AND CONTRIBUTE TO SEDIMENTATION. THE AMOUNT OF CLASTIC SEDIMENTS DEPOSITED IN THIS MANNER IS SIGNIFICANT, FOR EXAMPLE, IN THE 113-MILE-LONG DELTA-MENDOTA CANAL IN THE WESTERN SAN JOAQUIN VALLEY, CALIFORNIA. THE SEDIMENTS CONSIST OF 20-35% 'FINES' WHICH WERE PROBABLY PRECIPITATED AS EXCRETA, 35-50% SAND, AND 30% CLAMSHELLS. HIGHLY EUTROPHIC, TURBID DELTAIC WATER WHICH IS PUMPED INTO THE CANAL SUPPORTS AN ABUNDANT, VARIED BIOTA.ASIATIC CLAMS (CORBICULA FLUMINEA) ARE PARTICULARLY NUMEROUS. THE AVERAGE NUMBER OF LIVE CLAMS PER SQ FT OF SEDIMENTS IS IN THE ORDER OF 1000. LABORATORY PUMPING RATE OF A ONE-YEAR CORBICULA APPEARS TO BE ABOUT 20 CC/HOUR. THERE IS A GENERAL DECLINE OF CLAM INFESTATION IN THE DOWNSTREAM DIRECTION, AWAY FROM THE DELTA: IN 1965-66, BIOMASSES OF CORBICULA DECLINED FROM ABOUT 140 (POOL 1) TO 25 (POOL 18) TONS PER LINEAR MILE. AVERAGE SEDIMENTATION RATES DECLINE FROM ABOUT 292 CU YD/MI/YR IN POOLS 1 THROUGH 5, TO 9 CU YD/MI/YR IN POOLS 15 THROUGH 19. APPARENTLY SMALLER PUMPING-DEPOSITION OF SUSPENDED PARTICLES BY CLAMS IN DOWNSTREAM REACHES RESULTS IN CORRESPONDINGLY LOWER SEDIMENTATION RATES.

BY THE MID-1940'S, FREEZE-THAW TESTING OF CONCRETE WAS ADOPTED AS AN ACCEPTANCE TEST FOR CONCRETE AGGREGATES AND AUTOMATICALLY CONTROLLED EQUIPMENT WAS BUILT. THE APPARATUS TESTS 3-IN.-DIA SPECIMENS CONTAINED IN RUBBER TUBES AND COVERED WITH TAP WATER. TEST SPECIMENS ARE ALTERNATELY FROZEN AND THAWED BY RECIRCULATING REFRIGERATED BRINE AND HEATED BRINE SYSTEMS. A LARGE WALK-IN AIR-FREEZE AND WATER-THAW APPARATUS WAS BUILT IN L956 TO ACHIEVE GREATER FLEXIBILITY FOR TESTING LARGE OR UNUSUALLY SHAPED SPECIMENS AND FOR VARYING THE PERIOD OF FREEZING AND THAWING. RESULTS OF FREEZE-THAW STUDIES ARE SUMMARIZED ON AIR ENTRAINMENT, EFFECTS FROM FINENESS OF GRINDING PORTLAND CEMENT, CORRELATION WITH SODIUM SULFATE SOUNDNESS TESTS, AND CORRELATION WITH FIELD PERFORMANCE. EXACT CORRELATION BETWEEN LABORATORY TESTS AND FIELD PERFORMANCE HAS NOT BEEN ACHIEVED BECAUSE OF THE MANY VARIABLES THAT CANNOT BE FULLY EVALUATED.

THE PARAMETERS NEEDED ARE POISSON'S RATIO AND MODULUS OF DEFORMATION. A METHOD OF STUDYING THE RATIO IS TO PERFORM TRIAXIAL TESTS HOLDING LATERAL STRAIN TO ZERO; AS THE VERTICAL STRESS IS INCREASED, ANY TENDENCY FOR LATERAL DEFORMATION IS RESISTED BY AN INCREASE IN CHAMBER PRESSURE. THE PROCEDURE IS REFERRED TO AS A K SUB O TEST, K SUB O BEING THE NOTATION FOR COEFFICIENT OF EARTH PRESSURE AT REST. TWO GRAVELS WITH A MAXIMUM PARTICLE SIZE OF 3 IN. WERE STUDIED. GRAVEL A WAS POORLY GRADED AND FREE DRAINING, AND GRAVEL B CONTAINED CONSIDERABLE SILTY AND CLAYEY FINES AND WAS RELATIVELY IMPERVIOUS. EACH GRAVEL WAS TESTED AT 2 GRAVEL CONTENTS, 50 AND 65%. THE SPECIMEN SIZE FOR ALL TESTS WAS 6 IN. IN DIAMETER BY 15 IN. HIGH. THE TESTS WERE CONDUCTED UNDER CHAMBER PRESSURES VARYING FROM ZERO TO 1000 PSI. THE K SUB O VALUES FOR BOTH GRAVELS AND GRAVEL CONTENTS WERE IN THE RANGE OF 0.2 TO 0.4. THE VALUES OF POISSON'S RATIO WERE THE SAME FOR ALL TESTS, RANGING FROM ABOUT 0.15 TO 0.30.

A SERIES OF DISCHARGE MEASUREMENTS WAS MADE IN 1968, AT FLATIRON POWER AND PUMPING PLANT NEAR LOVELAND, COLO, TO EVALUATE TECHNIQUES AND EQUIPMENT. MEASUREMENTS WERE MADE ON A 6000-FT-LONG, 6-FT-DIA PENSTOCK AT A DISCHARGE OF 300 CFS. THIRTY-SEVEN INJECTIONS OF RADIOACTIVE BROMINE-82 WERE MADE FOR DISCHARGE MEASUREMENTS BY THE VELOCITY METHOD, 17 FOR THE INTEGRATED-SAMPLE METHOD, AND 8 FOR THE DILUTION METHOD. THE INJECTIONS ENABLED COMPUTATION OF 33 DISCHARGES BY THE VELOCITY METHOD, 26 BY THE INTEGRATED SAMPLE METHOD, 45 BY THE DILUTION METHOD, AND 34 BY THE TOTAL-COUNT METHOD. A 4-POINT INJECTION SYSTEM, 45 DEG FROM THE VERTICAL AND HORIZONTAL CENTERLINES OF THE PIPE, WAS USED FOR MOST MEASUREMENTS. MIXING LENGTHS RANGED FROM 36 TO 919 PIPE DIAMETERS. MIXING LENGTHS OF 100 PIPE DIAMETERS PRODUCED THE SAME ORDER THE ACCURACY AS MIXING LENGTHS OF 919 DIAMETERS. STUDIES ARE CONTINUING TO INCREASE MEASUREMENT ACCURACY USING PIPE LENGTHS AS SHORT AS 30 PIPE DIAMETERS.

FEDERAL RECLAMATION PROJECTS HAVE BEEN DESIGNED TO HELP MEET THESE NEEDS AND PLAY AN INCREASINGLY IMPORTANT ROLE IN SUPPLYING FUTURE NEEDS. NATIONAL PHILOSOPHY HAS BEEN THAT ALL RECLAMATION PROJECT COSTS FOR THE PURPOSE OF IRRIGATION, POWER, AND MUNICIPAL AND INDUSTRIAL SUPPLY SHOULD BE REPAID IN FULL. REPAYMENT OF ALL REIMBURSABLE PROJECT COSTS AND OPERATION AND MAINTENANCE COSTS IS A RESPONSIBILITY OF PROJECT BENEFICIARIES. MUNICIPAL AND INDUSTRIAL WATER SUPPLY COSTS ARE REPAID IN 50 YR (WITH INTEREST) BY REVENUES FROM WATER USERS. MANY WESTERN CITIES RELY ON WATER SUPPLIES DEVELOPED OR BEING DEVELOPED BY RECLAMATION, AND DEMAND IS INCREASING WITH POPULATION EXPANSION. MUNICIPAL AND INDUSTRIAL WATER DEMANDS IN THE WESTERN WATER REGIONS FOR A POPULATION OF OVER 160 MILLION BY THE YR 2020 ARE ESTIMATED TO INCREASE FROM 7.8 TRILLION GAL. IN 1965 TO 62.1 TRILLION GAL. IN 2020.

FACTORS INFLUENCING THE CHANGING ROLE OF GROUNDWATER RESERVOIRS ARE: (1) NON-AGRICULTURAL USES INCREASING FASTER THAN AGRICULTURAL ONES, (2) MUNICIPAL AND INDUSTRIAL WATER REQUIREMENTS DISPLACING THE SAME LAND AREAS PREVIOUSLY DEVOTED TO IRRIGATED AGRICULTURE, (3) WATER THAT WAS PREVIOUSLY REQUIRED FOR AGRICULTURE IS USUALLY MORE THAN AMPLE TO PROVIDE FOR THIS CHANGING USE, AND (4) THIS TRANSITION OF USE MAKES MORE WATER AVAILABLE FOR REUSE AT LOCALIZED POINTS AND WITH MORE CONVENIENCE THAN WOULD BE ASSOCIATED WITH RETURN FLOW FROM IRRIGATION. THESE CHANGING CONDITIONS REQUIRE THAT GROUNDWATER RESERVOIRS NOW MUST ASSUME DIVERSE FUNCTIONS BEYOND SIMPLE EXPLOITATION AND BECOME PART OF A TOTAL WATER RESOURCE SYSTEM. TOTAL WATER RESOURCE SYSTEM PLANNING, WITH THE USE OF COMPUTER-ORIENTED TECHNIQUES, WILL ASSUME NEW IMPORTANCE IN THE ARID LANDS OF THE WESTERN UNITED STATES.

THE BUREAU OF RECLAMATION HAS MADE THE FOLLOWING ADVANCES IN MEASURING NEGATIVE PORE PRESSURES: (1) THE EXPOSED END PLATE METHOD OF MEASURING THE INITIAL NEGATIVE PORE PRESSURE OF SOILS. NEGATIVE PORE PRESSURE CAN BE DETERMINED ON A ROUTINE LABORATORY TESTING BASIS WITHOUT DAMAGING THE SPECIMENS FOR FURTHER TESTING. (2) MEASURING CAPILLARY PRESSURE THROUGHOUT THE VOLUME CHANGE RANGE AS THE UNDRAINED (SEALED) SPECIMENS ARE COMPRESSED FROM INITIAL NEGATIVE PORE PRESSURE TO THE POINT WHERE THE CAPILLARY PRESSURE BECOMES ZERO AT SATURATION. RESULTS OF THIS TEST CONDUCTED ON ONE OF A SERIES OF SPECIMENS, TOGETHER WITH RESULTS OF THE EXPOSED END PLATE TEST ON EACH SPECIMEN OF THE SERIES ARE APPLIED IN THE ANALYSIS OF SOIL STRENGTH FROM SHEAR TEST RESULTS. (3) IMPROVED ACCURACY IN MEASURING PORE AIR PRESSURE BY SEPARATING THE WATER FILM IN THE SOIL FROM THE END PLATE MEASURING DEVICE AND CONTROLLING THE END PLATE SO THAT WATER IS NOT DRAWN INTO OR FROM THE SOIL. VARIABLE SOIL STRESS CONDITIONS THAT WOULD BE INTRODUCED BY CHANGING SOIL MOISTURE CONDITIONS ARE ELIMINATED. (USBR) JF - BUR RECLAM REP NO EM-761, JUNE 1969. 56 P, 38 FIG, 3 TAB, 10 REF, 3 APPEND.

HARDENING IS INDICATED BY A DECREASE IN PENETRATION AND DUCTILITY AND AN INCREASE IN SOFTENING POINT. THESE CHANGES WERE REFLECTED IN THE AGING INDEXES. THE 14-DAY AGING TEST PRODUCED GREATER ASPHALT HARDENING. AN AGING INDEX OF 63.4 WAS OBTAINED FOR ASPHALT CEMENTS SUBJECTED TO THE 14-DAY AGING TEST, COMPARED TO AN AGING INDEX OF 73.7 FOR SAMPLES OF THE SAME ASPHALT CEMENTS SUBJECTED TO THE THIN FILM OVEN TEST. NEW ASPHALT CEMENTS, BY DEFINITION, HAVE AN AGING INDEX OF 100. COMPARING LABORATORY AGING WITH FIELD AGING INDICATED THAT THE 14-DAY, 140 DEG F OVEN AGING TEST PRODUCED ASPHALT HARDENING SIMILAR TO THAT OBTAINED AT 14 YR FIELD EXPOSURE.

THE PERFORMANCE OF THE ANCHOR BAR FOOTING IN SANDY SILT WAS OF SPECIAL INTEREST. THE STRAIGHT AUGER, BELLED AUGER, AND PRESSED PLATE FOOTINGS WERE TESTED TO PROVIDE A COMPARISON WITH THE ANCHOR BAR FOOTING RESULTS. EACH FOOTING WAS TESTED IN NATURAL AND PONDED SOILS CONDITIONS. FOR THE ANCHOR BAR FOOTING AT VERTICAL FAILURE MOVEMENT (1/2 IN.), THE LOAD RESISTED WAS OVER 110 KIPS IN NATURAL SOIL AND ABOUT 115 KIPS IN PONDED SOIL. FOR THE OTHER 3 TYPES OF FOOTINGS, LOADS AT VERTICAL FAILURE MOVEMENT WERE: 55 TO 105 KIPS FOR STRAIGHT AUGER, 80 TO 100 KIPS FOR BELLED AUGER, AND 17.5 TO 25.0 KIPS FOR PRESSED PLATE. DESIGN LOADS WERE 28.7 KIPS FOR CONCRETE FOOTINGS AND FROM 14.1 TO 18.0 KIPS FOR PRESSED PLATE FOOTINGS. SOIL SAMPLES WERE ANALYZED IN THE LABORATORY.

THE BULK OF THE COST OF THE STORAGE PROJECT IS BEING PAID BY POWER PRODUCTION. PROJECT WATER USE COMES IN THE FORM OF ELECTRIC ENERGY OVER A WIRE. PROJECT POWER INCOME IS NOW ABOUT $20 MILLION PER YEAR. WITH THE COMBINED EFFECT OF STREAMFLOW PLUS THE HEAD VERSUS VOLUME RELATIONSHIP BEING UNIQUE AT EACH RESERVOIR WITH A POWERPLANT, THE DISTRIBUTION OF STORAGE AMONG THE RESERVOIRS IS AIMED AT DEVELOPING MAXIMUM SYSTEMS ENERGY AND CAPACITY. THE STREAMFLOW FORECASTING METHOD USED BY THE BUREAU OF RECLAMATION IS BASED ON A CORRELATION OF STREAMFLOW AT A PARTICULAR SITE WITH THE ACCUMULATED PRECIPITATION AT SELECTED GAGING STATIONS PLUS SNOW DEPTHS AT SPECIFIC COURSES WITHIN THE CONTRIBUTING DRAINAGE BASIN. ABOVE GLEN CANYON DAM, THE BUREAU USES PRECIPITATION STATIONS AND 48 SNOW COURSES. EMPHASIS IS PLACED ON THE APPLICATION OF THE PROBABILITY OF THE FORECAST RUNOFF DEVIATING FROM THE ACTUAL RUNOFF. MOST MANAGEMENT DECISIONS RECOGNIZE A DEVIATION RANGE EXCEEDED LESS THAN ONE OUT OF TEN TIMES IN THE PAST.

LIQUEFACTION IS A CRITICAL PROBLEM IN LOW-DENSITY SANDS AND SILTS WHEN SATURATED AND A REAL DANGER DURING EARTHQUAKES. THE FOUNDATION ENGINEER MUST DETERMINE THE CRITICAL NATURE OF IN SITU CONDITIONS. THE STANDARD PENETRATION-RESISTANCE TEST IS USEFUL FOR EVALUATING RELATIVE DENSITY OF SAND DEPOSITS AND CHECKING THIS CONDITION AFTER DENSIFICATION. LABORATORY TESTS OF SANDS AT VARIOUS CONDITIONS, USING CYCLIC LOADS AND THE NUMBER OF CYCLES TO REPRESENT EARTHQUAKE EFFECTS, MAY BE PERFORMED TO DETERMINE SHEAR STRESSES NECESSARY FOR LIQUEFACTION AND FAILURE. SEISMIC COEFFICIENTS AND DESIGN EARTHQUAKES ARE SELECTED FROM A REVIEW OF THE EARTHQUAKE HISTORY IN THE CONSTRUCTION AREA TO COMPUTE EXPECTED SHEAR STRESSES FOR COMPARISON WITH SHEAR STRESSES NECESSARY TO CAUSE LIQUEFACTION. THE PRACTICING FOUNDATION ENGINEER IS CONCERNED MOSTLY WITH ACCEPTABLE DENSITIES IN SANDS SUSCEPTIBLE TO LIQUEFACTION AND COHESIVE SOILS COMPACTED IN EMBANKMENTS.

THE MOST OBVIOUS REASONS FOR USING ELECTRONIC COMPUTING EQUIPMENT ARE: TO REDUCE THE TIME AND COST REQUIRED TO CARRY OUT NUMERICAL CALCULATIONS; TO PROVIDE MORE DATA UPON WHICH MORE INTELLIGENT DECISIONS CAN BE BASED; AND TO FREE THE ENGINEER OR SCIENTIST FROM THE DRUDGERY OF ROUTINE MANUAL COMPUTATIONS.

FOR EXAMPLE, SIMULATION OF GROUND-WATER SYSTEMS ON A DIGITAL COMPUTER AND ANALYSIS OF WATER QUALITY REQUIREMENTS ARE INTIMATELY INTERCONNECTED. TO ANALYZE WATER RESOURCE PROBLEMS IN AN APPROPRIATE MANNER, THE BUREAU OF RECLAMATION IS ATTEMPTING TO INTEGRATE SURFACE WATER SYSTEMS, GROUND-WATER SYSTEMS, AND WATER QUALITY CONTROL IN PROJECT PLANNING AND OPERATION STUDIES. SUCH INTEGRATED ANALYSES ARE POSSIBLE ONLY BY USING HIGH-SPEED ELECTRONIC COMPUTING EQUIPMENT.

The general historical, cultural and environmental setting in which European land policy developed is reviewed in Chapter 1. Chapter 2 discusses the growing scarcity of urban land in Europe, and the actions taken by European governments. Chapter 3 focuses briefly on European physical planning principles and processes, and their increasingly close relationships with economic planning. It also examines the methods used to carry out such planning to achieve more socially and economically desirable land use. Chapter 4 reviews the available data on major European growth patterns, and considers the comparative costs of alternative forms of urban expansion. The role played by infrastructure as a tool of urban land policy, with particular attention to the development of urban centers in economically lagging areas, is examined in Chapter 5. Chapter 6 summarizes and comments on the lessons learned from European experience. (Lantz-PTT) JF - Department of Housing and Urban Development, Washington DC.

A PROCEDURE FOR CONTROLLING THREE CANADIAN WELLS IS OUTLINED. BASICALLY, THE METHOD CONSISTS OF USING A BENTONITE MUD TO TEMPORARILY COMPLETELY SHUT OFF THE FLOW OF WATER IN BOTH CASING AND ANNULAR SPACE, AND THEN DISPLACING THE MUD WITH CEMENT FROM THE BOTTOM BY MEANS OF A PERFORATED DROP PIPE. IT IS EMPHASIZED THAT ALL EQUIPMENT AND MATERIALS SHOULD BE ASSEMBLED AT THE WORK SITE IN ORDER THAT THE CEMENT BE PLACED BEFORE THE MUD GELS. IF THE MUD GELS, HIGHER PUMPING PRESSURES ARE REQUIRED FOR DISPLACEMENT OF THE MUD. ALTHOUGH NOT INEXPENSIVE, THIS PROCEDURE SHOULD BE CHEAPER THAN DRILLING A NEW WELL.

THIS CHANGE IS THE SUBSTITUTION OF MACHINE POWER FOR HUMAN POWER WHENEVER POSSIBLE. THE PRINCIPAL REASON FOR THE CHANGE IS THAT TODAY'S HIGHLY SKILLED WORKMEN ARE USED MOST ECONOMICALLY WHEN THEIR SKILLS AND NOT THEIR MUSCLES ARE EXPLOITED. WHILE THE USE OF AVAILABLE SKILLS IS BASICALLY THE CONSTRUCTION CONTRACTOR'S PROBLEM, THE DESIGN ENGINEER HAS THE RESPONSIBILITY TO GIVE THE CONTRACTOR THE OPPORTUNITY FOR OPTIMUM USE OF THE SKILLS AND POWER OF HIS CRAFTSMEN. FOR EXAMPLE, WITH CONSTRUCTION CONTRACTORS PROPOSING UNIT PRICES FOR CONCRETE OF $200 AND MORE, THE DESIGNER MUST RECOGNIZE THAT THE CHEAPEST COMPONENTS OF STRUCTURAL CONCRETE ARE CEMENT AND AGGREGATE. COSTS ARISE FROM WASTEFUL USE OF HIGHLY SKILLED WORKMEN IN FABRICATING AND SETTING INTRICATE FORMS AND UNNECESSARY REQUIREMENTS FOR PLACING CONCRETE IN CONFINED AND CONGESTED FORMS.

THE BUREAU REACHED THE FOLLOWING CONCLUSIONS: (1) THE MOST SIGNIFICANT FACTOR IN DETERMINING ECONOMIC JUSTIFICATION FOR CANAL LINING IS THE VALUE OF WATER WHICH THE LINING CONSERVES. (2) CANAL LININGS ARE GENERALLY ECONOMICALLY JUSTIFIED IN AREAS WHERE IRRIGABLE LAND EXCEEDS AVAILABLE WATER SUPPLY. (3) OTHER TANGIBLE BENEFITS OF CANAL LINING INCLUDE REDUCED RIGHT-OF-WAY COSTS, REDUCED INVESTMENT COSTS FOR STORAGE AND DRAINAGE SYSTEMS, AND REDUCED OM AND R COSTS. (4) AMONG THE INTANGIBLE BENEFITS ARE SUCH ITEMS AS IMPROVED SAFETY AND FARM APPEARANCE AND REDUCTION IN WATER CONTAMINATION BY HERBICIDES. STUDY OF A SAMPLE AREA SHOWED THAT LINED CANALS WITH OPEN-LINED LATERALS HAD THE HIGHEST BENEFIT-COST RATIO AND THE GREATEST EXCESS OF BENEFITS OVER COSTS. (SEE W70-06026).

MUCH SOPHISTICATED AND EXOTIC EQUIPMENT IS AVAILABLE FOR RESEARCH INSTRUMENTATION, BUT A SIMPLE INSTRUMENTATION SYSTEM IS ADEQUATE FOR MOST ROUTINE STRUCTURES. COLLECTING AND EVALUATING PERFORMANCE DATA ARE CONTINUING OPERATIONS. THE PROCESS PRODUCES CRITICAL AND INTERESTING DATA SO INFREQUENTLY THAT WITHOUT SPECIAL EFFORT AN INSTALLATION MAY BE NEGLECTED OR ABANDONED BEFORE AN EVENT OCCURS THAT PRODUCES SIGNIFICANT RESULTS. AN EARTH DAM HAS 3 PRINCIPAL PROPERTIES WHOSE VARIATION DURING THE LIFE OF THE STRUCTURE IS OF INTEREST: RESISTANCE TO WATER MOVEMENT, RESISTANCE TO DEFORMATION, AND STRENGTH. THE GENERAL PRINCIPLES BY WHICH DATA COLLECTED FROM AN INSTRUMENT SYSTEM CAN BE ANALYZED TO PRODUCE AN UNDERSTANDING OF BEHAVIOR ARE DESCRIBED. A FEW OF THE MORE NOTICEABLE BEHAVIOR OBSERVATIONS ARE DESCRIBED AND OPPORTUNITIES FOR FURTHER EXPANSION OF STRUCTURAL BEHAVIOR THROUGH STRUCTURE INSTRUMENTATION ARE LISTED.

ONE FACTOR GREATLY INFLUENCING THE ACTIVATION PROCESS IS THE CHLORIDE ION. THIS STUDY WAS MADE ON THE MECHANISM OF PASSIVATION AND DEPASSIVATION OF STEEL IN A SIMULATED CONCRETE ENVIRONMENT UNDER THE CONTROLLING INFLUENCE OF THE CHLORIDE ION. TESTS WERE PERFORMED TO DETERMINE WHETHER (1) PASSIVATED STEEL TENDS TO MAINTAIN PASSIVITY WHEN EXPOSED TO A NONPASSIVATING ENVIRONMENT, (2) CHLORIDE IONS TEND TO ACCELERATE DEPASSIVATION OF STEEL, OR (3) FILM FORMATION IS RETARDED BY THE PRESENCE OF CHLORIDE. RESULTS INDICATED THAT: (1) DEPASSIVATION OF STEEL OCCURS QUICKLY AFTER REMOVAL OF THE PASSIVATING ENVIRONMENT; (2) CHLORIDE ACCELERATES FILM BREAKDOWN IN THE CASE OF A PASSIVATED SPECIMEN AND AIDS IN ESTABLISHING ACTIVE CORROSION CELLS IN UNPASSIVATED SPECIMENTS; AND (3) THE PRESENCE OF 0.08M CHLORIDE IN NORMALLY PASSIVATING SOLUTIONS OF SATURATED CALCIUM HYDROXIDE IS SUFFICIENT TO PREVENT PASSIVATION OF STEEL, AND CORROSION CAN OCCUR (SUBJECT TO LOCAL CONDITIONS) AT CHLORIDE CONCENTRATIONS AS LOW AS 0.02M.

THE ANCHOR BAR FOOTING CONSISTS OF A REINFORCED CONCRETE CAP WITH 4 ANCHOR BARS (REINFORCING BARS SURROUNDED BY GROUT) EXTENDING OUT OF THE CAP BASE DOWNWARD INTO THE SOIL. AT THE FAILURE MOVEMENT OF 1/2 IN., THE UPLIFT LOAD WAS ABOUT 30 KIPS AND THE MAXIMUM UPLIFT LOAD RESISTED WAS 48 KIPS. MOST FOOTING MOVEMENT WAS CAUSED BY ROTATION RATHER THAN TRANSLATION. THE SOIL RESISTING THE FOOTING MOVEMENT WAS A SANDY SILT AND A LEAN CLAY. FOR AN INDIVIDUAL ANCHOR BAR, SOIL STRENGTH VALUES INDICATED THAT ABOUT 3.5 KIPS COULD BE RESISTED, WHILE A STATIC ANALYSIS INDICATED THAT ABOUT 8.2 TO 10.7 KIPS WERE ACTUALLY RESISTED. THE DIFFERENCE BETWEEN COMPUTED AND ACTUAL LOADS IS ATTRIBUTED MAINLY TO THE FOLLOWING FACTORS NOT INCLUDED IN THE COMPUTATIONS: (1) THE DIRECTION OF THE LOAD WAS OBLIQUE TO THE AXIS OF THE ANCHOR BAR, AND (2) A 1-1/2-FT SECTION OF THE GROUTED HOLE IN A SAND AND GRAVEL LAYER HAD AN ENLARGED DIAMETER. THE ANALYSIS WAS COMPLICATED BECAUSE THE BOTTOM ONE-THIRD TO ONE-HALF OF THE ANCHOR BAR REINFORCEMENTS EXTENDED INTO SOIL OUTSIDE THE GROUTED HOLES.

WATER TESTS OF EXPLORATORY HOLES ARE THE MOST COMMONLY USED INDICATORS FOR ESTIMATING DRILLING AND GROUTING QUANTITIES. GROUTING SPECIFICATIONS SHOULD REMAIN FLEXIBLE TO ALLOW THE FOUNDATION TREATMENT TO BE MODIFIED TO FIT THE CONDITIONS AS THE FOUNDATION IS UNCOVERED AND DRILLING AND GROUTING GET UNDERWAY DURING CONSTRUCTION. THE GENERAL GROUT PLAN FOR THE HYPOTHETICAL DAM PROVIDES FOR SHALLOW LOW-PRESSURE BLANKET GROUTING TO FILL VOIDS IN THE CAVERNOUS LIMESTONE NEAR THE SURFACE TO PROTECT THE DAM EMBANKMENT AND FOUNDATION CONTACT. TWO DEEP, HIGH-PRESSURE GROUT CURTAINS WILL PROVIDE A CUTOFF AND INCREASE THE PERCOLATION PATH UNDER THE DAM. THE CIRCULATING LINE AND MANIFOLD OF THE GROUT EQUIPMENT ARE VITAL TO CLOSELY REGULATE GROUT PRESSURES. THE METHOD OF CLOSURES OR SPLIT SPACING DETERMINES WHEN THE GROUT PROGRAM IS ADEQUATE. USING A GROUT WITH AN OPTIMUM WATER-CEMENT RATIO WITHOUT SLUGGING THE HOLE IS ESSENTIAL FOR REPAIRING THE FOUNDATION TO FIT REQUIREMENTS FOR A SAFE STRUCTURE.

THE MAIN CONCERN AT RUEDI WAS THAT THE GYPSUM WAS A PLUG CONTAINING MAJOR CAVITIES AND CHANNELS OR THAT THE GYPSUM WOULD DISSOLVE; EITHER SITUATION WOULD PROVIDE MAJOR ESCAPE ROUTES FOR THE RESERVOIR WATER. EXTENSIVE EXPLORATIONS SHOWED THAT GYP HILL WAS FORMED BY GYPSUM BEDS DEFORMING UNDER PLASTIC FLOW UNDER RELATIVELY LOW DIFFERENTIAL STRESSES. THIS PROCESS PREVENTS LARGE OPENINGS FROM DEVELOPING BY SOLUTION AT GREAT DEPTHS. THE PLASTICITY OF THE GYPSUM RENDERS THE MASS ESSENTIALLY IMPERVIOUS TO ANY LARGE PASSAGE OF WATER, ESPECIALLY DOWNSTREAM OF RUEDI DAM WHERE THE LOAD CONSISTS OF OVER 4000 FT OF ROCK. DESIGN FEATURES INCORPORATED IN CONSTRUCTING THE DAM INCLUDED: (1) SELECTIVE EXCAVATION, (2) EXTENSIVE GROUTING, AND (3) ROCK BOLTING. THE DAM WAS COMPLETED IN 1968, AND IMPOUNDED WATER TO A DEPTH OF OVER 190 FT THE FIRST YEAR. (USBR) JF - PAP, WATER RESOUR ENG CONF, AMER SOC CIV ENG, NEW ORLEANS, LA, FEB 1969. 28 P, 9 FIG, 4 REF.

THE PARTIAL SOLUTIONS WHICH ARE AVAILABLE TO US ARE ENCOMPASSED BY TWO BROADER CATEGORIES, (1) THOSE ACTIVITIES WHICH ARTIFICIALLY AUGMENT NATURAL WATER SOURCES, AND (2) THOSE MEASURES WHICH OBTAIN THE MAXIMUM BENEFICIAL USE OF A GIVEN WATER SUPPLY. THE PARTIAL SOLUTIONS IN THE FIRST CATEGORY INCLUDE (1) PRECIPITATION MANAGEMENT OR 'CLOUD SEEDING,' (2) DESALINATION OF OCEAN WATER, AND (3) INTERBASIN TRANSFERS. CONTROLLED EXPERIMENTS SUGGEST THAT PRECIPITATION MANAGEMENT MAY WELL BE A VIABLE ALTERNATIVE, WHILE OTHER STUDIES INDICATE THAT LARGE-SCALE DESALINATION PLANTS COULD POSSIBLE PRODUCE RELATIVELY CHEAP WATER. SOLUTIONS IN THE SECOND CATEGORY INCLUDE (1) WASTE WATER RENOVATION, (2) NATURAL POLLUTION ABATEMENT, (3) WATERSHED TREATMENT, (4) WATER HARVESTING THROUGH SOIL TREATMENT, (5) PHREATOPHYTE ERADICATION AND CONTROL, (6) GROUNDWATER RECOVERY, (7) EVAPORATION REDUCTION, (8) IMPROVEMENTS IN CANAL LINING, AND (9) IMPROVEMENTS IN WATER SCHEDULING. THE NEED FOR THESE PARTIAL SOLUTIONS IS ILLUSTRATED BY THE CENTRAL ARIZONA PROJECT WHICH DOES NOT SUPPLY ENOUGH WATER TO MEET THE NEEDS OF THE AFFECTED AREA.

NITRATE CONTENT OF WATER BEFORE IRRIGATION AND OF DRAINAGE WATER WAS OF SPECIFIC INTEREST. DURING 30-YEAR PERIOD AMOUNT OF NITROGEN FERTILIZER APPLIED INCREASED BY 35- TO 100-FOLD. DECREASING ANNUAL RIVER FLOWS WERE MAJOR CAUSE OF SIGNIFICANT INCREASE OF AVERAGE ANNUAL NITRATE LOAD OF RIVER BETWEEN 1954-1963 PERIOD. INCREASED USE OF NITROGEN FERTILIZER IN THREE AREAS HAS NOT INCREASED OVERALL NITRATE NITROGEN IN UPPER RIO GRANDE. EL PASO VALLEY HAS SLIGHTLY INCREASED RIVER NITRATE NITROGEN DUE TO VERY LOW FLOWS AND SEWAGE EFFLUENT. INSIGNIFICANT CONTRIBUTION OF NITRATE NITROGEN LOAD TO RIVER FROM RINCON AND MESILLA VALLEYS WAS RESULT OF DENITRIFICATION OF LEACHED NITRATE NITROGEN UNDER ANAEROBIC CONDITIONS IN WATER SATURATED SOIL.

OTHER IMPORTANT SOCIAL AND ECONOMIC GOALS MAY BE IDENTIFIED UNDER THE OVERRIDING MANDATE TO ENHANCE THE WELL-BEING OF THE PEOPLE--REGIONAL GROWTH, PROVISION OF ECONOMIC OPPORTUNITY, STABILIZATION OF COMMUNITIES, AND PROVISION OF A SATISFYING HUMAN ENVIRONMENT. QUANTITATIVE MEASURES OF THESE DEVELOPMENTAL OR OPPORTUNITY GOALS ARE NEEDED IN ADDITION TO PRESENT MEASURES OF ECONOMIC EFFICIENCY. A COMPREHENSIVE ANALYSIS OF MEANS TO ACHIEVE THESE GOALS SHOULD RECOGNIZE ALTERNATIVE WATER MANAGEMENT SCHEMES AND ALTERNATIVE APPROACHES SUCH AS TRANSPORTATION IMPROVEMENT, BUSINESS STIMULATION, AND PROVISION OF INCREASED EDUCATIONAL OPPORTUNITIES IN ECONOMICALLY LAGGING AREAS.

PRELIMINARY EXPLORATION INDICATED THAT THE GENERAL QUALITY OF THE ROCK WAS EXCELLENT, BUT BECAUSE OF FAULTS, JOINTS, AND CLAY SEAMS, EXTENSIVE GEOLOGICAL INVESTIGATIONS AND MAPPING WERE REQUIRED TO OBTAIN SUFFICIENT INFORMATION FOR THE FINAL DESIGN OF THE DAM AND APPURTENANT STRUCTURES. DIAMOND DRILL CORING, SEISMIC STUDIES, AND DRILL HOLE PERCOLATION TESTS WERE PERFORMED. SOME PROBLEMS ANTICIPATED WERE SEEPAGE, EXTRA EXCAVATION TO REACH SOUND ROCK, AND PINNING OF CERTAIN AREAS TO PREVENT POSSIBLE MOVEMENT. THE SEEPAGE PROBLEM WAS RELATIVELY MINOR, REQUIRING EXTENSION OF THE MAIN CUTOFF GROUT CURTAIN DEEPER INTO BOTH ABUTMENTS. ABUTMENT ROCK WAS PINNED TO ASSURE STABILITY AND TO PREVENT ROCKFALLS. SHALE SEAMS IN THE KEYWAY AREAS WERE TREATED BY PLACING CONCRETE CUTOFF WALLS IN THE SHALE BEDS AT THE HEEL AND TOE OF THE DAM. AS THE RESERVOIR WAS FILLED FOR THE FIRST TIME, SEVERAL SMALL SLUMPS OCCURRED IN SLOPES ALONG THE SIDES OF THE RESERVOIRS. ONE MOVEMENT OF A LARGE BLOCK OF ROCK PRESENTED A POTENTIAL HAZARD TO BOATERS AND IS UNDER CAREFUL OBSERVATION. AT THE PRESENT TIME, THE LANDSLIDE AREAS ARE NOT CONSIDERED HAZARDOUS.

THE FORMING PROCESSES OF SOILS ARE MANY AND VARIED. THESE PROCESSES PRODUCE NATURAL DEPOSITS AND FORMATIONS THAT ARE SELDOM HOMOGENEOUS, AND SOIL COMPONENTS HAVING A VARIETY OF CHARACTERISTICS. THE JOB OF THE SOILS ENGINEER IS LARGELY ONE OF INVESTIGATION TO DETERMINE PHYSICAL PROPERTIES OF THE MATERIAL AND REACTIONS OF THE SOIL MASS TO IMPOSED CONDITIONS. COMPARED WITH OTHER COMMON BUILDING MATERIALS, SOILS ARE DIFFICULT TO SAMPLE AND TEST. TO OBTAIN MEANINGFUL DATA FOR DESIGNING EARTH STRUCTURES AND FOUNDATIONS, CONSIDERATION MUST BE GIVEN TO GEOLOGICAL HISTORY, PRESENT CONDITIONS, CONSTRUCTION SEQUENCES, AND ANTICIPATED OPERATING CONDITIONS. PROPER CONSTRUCTION CONTROL PROCEDURES ARE IMPORTANT TO ASSURE THAT THE PROPERTIES ASSUMED IN THE DESIGN ARE OBTAINED. WHILE ADVANCES HAVE BEEN MADE IN THEORY, IN DETERMINING MEANINGFUL PARAMETERS, AND IN UNDERSTANDING SOIL MASS BEHAVIOR, PRACTITIONERS OF THE DISCIPLINE STILL RELY HEAVILY ON EMPIRICAL PROCEDURES AND JUDGMENT DEVELOPED BY TRAINING AND EXPERIENCE.

RESULTS WERE CORRELATED WITH THOSE FROM A SMALL NUMBER OF 6-IN.-DIA CORES FROM NONCRITICAL AREAS TO EVALUATE THE BRIDGE CONCRETE. ADDITIONAL TESTS WERE PERFORMED ON CONCRETE IN AREAS SHOWING MINOR DISTRESS. THE CONCRETE IN THE BRIDGE IS IN EXCELLENT CONDITION, HAVING A COMPRESSIVE STRENGTH OF 8700 PSI (612 KG/SQ CM) IN THE DECK AND 7630 PSI (536 KG/SQ CM) IN THE VERTICAL WALLS. PULSE VELOCITIES INDICATE THAT THE ARCH CONCRETE IS HIGH QUALITY AND THAT CONCRETE IN THE DECK IS SLIGHTLY LOWER IN QUALITY, PROBABLY BECAUSE OF MINOR DETERIORATION OF THE SURFACE CAUSED BY TRAFFIC.

RELIABLE TECHNIQUES AVAILABLE FOR SUCH SCHEDULING HAVE BEEN FIELD TESTED ON A FARM-BY-FARM BASIS. THESE TECHNIQUES MUST BE TESTED ON AN ENTIRE PROJECT BASIS. SEVERAL METHODS OF AUTOMATING ON-FARM IRRIGATION SYSTEMS HAVE BEEN USED ON A FIELD BASIS FOR DIFFERENT CROPS. RESEARCH BY PRIVATE INDUSTRY, STATE UNIVERSITIES, AND GOVERNMENT AGENCIES IS REFINING THESE METHODS AND DEVELOPING NEW METHODS. ELECTRONIC CONTROLS ARE AVAILABLE FOR REMOTE AND SUPERVISORY CONTROL, TELEMETERING, STREAM GAGING, AUTOMATIC GATE OPERATION, AND OTHER FORMS OF PROJECT IRRIGATION SYSTEM AUTOMATION. ALL OF THESE STEPS LEND THEMSELVES TO AUTOMATIC DATA PROCESSING AND, IN THE CASE OF LARGE IRRIGATION SYSTEMS, TO COMPUTER ANALYSIS TECHNIQUES. IMPLEMENTATION IS LARGELY DEPENDENT ON KNOWLEDGE OF THE VERY COMPLEX SOIL-WATER-PLANT RELATIONSHIP THAT MAKES PRECISE SCHEDULING DIFFICULT AND THE DIRECT EVIDENCE THAT AUTOMATION IS PROFITABLE FOR A FARMER AND PROJECT. ALTHOUGH REFINEMENTS MUST BE MADE IN EXISTING TECHNIQUES AND EQUIPMENT, 'IRRIGATION AUTOMATION' IS FAR MORE THAN A DREAM OR CLICHE.

THE INVESTIGATION DETERMINED THE ASSOCIATED COSTS AND BENEFITS AND GAVE BENEFIT-COST RATIOS. BENEFITS FROM DESALTING ARE GENERATED BY SHIFTS TO MORE PROFITABLE CROPPING PATTERNS, INCREASING CROP YIELDS, REDUCING WATER USE, REDUCING COSTS FOR WATER APPLICATION AND DRAINAGE, AND INCREASING THE FLOW OF FARM PRODUCTS. COSTS ARE BASED ON PROJECT FEATURES SUCH AS DESALTING PLANTS AND STEAM GENERATING EQUIPMENT, RAW WATER COLLECTION FACILITIES, STORAGE RESERVOIRS, CONVEYANCE AND DISTRIBUTION SYSTEMS, BRINE DISPOSAL SYSTEMS, BLENDING FACILITIES, GYPSUM ADDITION SYSTEMS, AND WATER TREATMENT FACILITIES. DESALTING IS EXPECTED TO FIND MANY IMPORTANT APPLICATIONS TO AGRICULTURE IN THE NEAR-TERM FUTURE.

PRECONSTRUCTION GEOLOGIC INVESTIGATIONS INDICATED THAT THE FOUNDATION WAS COMPETENT AND ESSENTIALLY WATERTIGHT. BECAUSE OF THE GEOLOGIC COMPLEXITIES AT THE SITE, DESIGN ENGINEERS WERE APPREHENSIVE OF THE INTERPRETATIONS OF THE GEOLOGISTS, PRINCIPALLY REGARDING THE COMPETENCE AND WATERTIGHTNESS OF THE FOUNDATION SITE. THE DESIGNERS' DISTRUST OF THE GEOLOGISTS' INTERPRETATION RESULTED IN A SIGNIFICANT OVERESTIMATE OF THE GROUTING REQUIREMENT AND AND A SUBSTANTIALLY HIGHER GROUTING COST THAN WOULD HAVE BEEN REQUIRED. DURING CONSTRUCTION, THE GEOLOGIC INTERPRETATIONS WERE FOUND TO BE ESSENTIALLY CORRECT. GEOLOGIC JUDGMENT WAS A CHALLENGING BUT NECESSARY PART OF PRECONSTRUCTION STUDIES FOR ARBUCKLE DAM.

A study was conducted on the aging characteristics of this lining. Of 112 field samples evaluated, over 80% demonstrated satisfactory membranes resistance to field aging, and should provide adequate seepage control for many years beyond the 14-year service age studied. A study is described on a method of reducing canal seepage by injecting an asphalt emulsion under the soil to form an impervious membrane. This application is intended for use in unlined canals with water delivery commitments that do not allow dewatering for conventional lining construction.

MODELS OF 2 ALTERNATIVE DESIGNS OF THIS RUNNER WERE TESTED AND THE DATA COMPARED WITH THAT OF RUNNER RO-697, THE FRANCIS RUNNER USED AT KRASNOIARSK. THE ONLY DIMENSIONAL DESIGN CHANGE IS THAT THE FLARE ANGLE OF THE LOWER BAND IS 13 DEG INSTEAD OF THE 20 DEG OF RO-697. THE MODEL TESTS AND DATA ANALYSIS LED TO THESE CONCLUSIONS: (1) SINCE SPECIFIC SPEED AND DISCHARGE CAPACITY OF THE COMBINED RUNNER ARE SIGNIFICANTLY HIGHER THAN FOR RO-697, USING THIS RUNNER AT KRASNOIARSK WOULD INCREASE UNIT CAPACITY AT THE GENERATOR TO 580 MW AND REDUCE THE TOTAL NUMBER OF UNITS BY ONE. (2) ENERGY FACTORS FOR THE IMPROVED MODEL DESIGN SHOWED THAT EFFICIENCY WAS ONLY 0.5 OR 1% LESS THAN THAT OF RO-697. (3) CAVITATIONAL QUALITIES WERE ABOUT EQUAL. (4) PRESSURE SURGES BEYOND THE NEW RUNNER WERE 30-40% LOWER THAN BEYOND RO-697, REDUCING TURBULENCE IN DESIGN OPERATING CONDITIONS AND ALSO DURING STARTUP AT REDUCED HEADS. THE COMBINED RUNNER'S GREATER DISCHARGE CAPACITY WILL INCREASE ITS OPERATIONAL RELIABILITY OVER THAT OF RO-697.

THE MAIN PROBLEM IS NOT A SHORTAGE OF WATER, BUT A SHORTAGE OF IDEAS, TECHNOLOGY, AND MANAGEMENT ABILITIES TO UTILIZE THE AVAILABLE SUPPLIES MORE EFFECTIVELY. TO SOLVE THIS PROBLEM, NEW RESEARCH, WELL FUNDED AND ORGANIZED, MUST BE UNDERTAKEN. NEW LEGISLATION BY CONGRESS, THE WATER RESOURCE RESEARCH ACT OF 1964, THE WATER RESOURCE PLANNING ACT OF 1965, THE WATER QUALITY ACT OF 1965, AND THE CLEAN WATER RESTORATION ACT OF 1966, HAS CONTRIBUTED TO ADVANCEMENTS IN RESEARCH PLANNING AND DEVELOPMENT. SEVEN GOALS ARE OUTLINED WHICH SHOULD DIRECT THE BASIC RESEARCH UNDERTAKEN. PRESENT EXPENDITURES IN FEDERAL RESEARCH EFFORTS ARE REVIEWED AND 'SHORT FALL AREAS' WHERE INVESTMENT IN RESEARCH HAS NOT BEEN SUFFICIENT ARE DISCUSSED. EIGHT POSSIBLE APPROACHES TO THE SOLUTION OF THE WATER PROBLEM: (1) PURIFICATION OR TREATMENT OF WASTES TO MAKE THE WATER USABLE; (2) REUSE TREATMENT AFTER EACH MAJOR USE; (3) RESTRICTED OR CURTAILED USE THROUGH METERING OR HIGHER CHARGES; (4) USE CLASSIFICATIONS FOR WATER QUALITY; (5) IMPROVED MANAGEMENT OF WATERSHEDS TO INCREASE WATER RECHARGE; (6) DESALTING; (7) WEATHER MODIFICATION; AND (8) IMPORTATION FROM OTHER AREAS.

THE MAIN ITEMS OF INVESTIGATION ON FLEXIBLE PIPE ARE SOIL PRESSURES ON THE PIPE AND LOAD-DEFLECTION RELATIONSHIPS. FIVE LOAD TESTS WERE PERFORMED ON BARE STEEL PIPE AND ONE TEST ON REINFORCED-PLASTIC MORTAR PIPE. PIPES ARE BURIED IN A PORTABLE SOIL CONTAINER 7 FT DEEP, 6 FT WIDE, AND 7 FT LONG, WITH SURCHARGE APPLIED TO THE SURFACE OF THE SOIL BY A LARGE UNIVERSAL TESTING MACHINE. MEASUREMENTS OF SOIL PRESSURES ON THE PIPE AND SOIL CONTAINER WALLS, CHANGING DIMENSIONS OF THE PIPE, SOIL MOVEMENT AROUND THE PIPE, AND STRAIN ON THE INNER SURFACE OF THE PIPE ARE MADE DURING A 1-DAY LOADING SEQUENCE. THE PROGRAM EVENTUALLY WILL COVER TESTS ON 18-, 24-, AND 30-IN.-DIA STEEL PIPE WITH WALL THICKNESS OF 7, 10, AND 14 GAGE. FURTHER TESTS ON REINFORCED-PLASTIC MORTAR PIPE WILL BE INCLUDED.

IN GENERAL TERMS DROUGHT IS A SUSTAINED PERIOD OF SIGNIFICANTLY SUBNORMAL WATER OR MOISTURE SUPPLY. TO DEFINE PRECISELY THE TERMS 'SUSTAINED PERIOD' AND 'SIGNIFICANTLY SUBNORMAL SUPPLY' IS DIFFICULT. THE GEOGRAPHIC DISTRIBUTION OF NATURAL ELEMENTS LIKE CLIMATE AND SOILS MAKES IT VIRTUALLY IMPOSSIBLE TO APPLY THE SAME PRECISE DEFINITION TO ALL AREAS. THE HYDROLOGIST USUALLY THINKS OF DROUGHT IN TERMS OF A DEFICIENCY IN PRECIPITATION OR RUNOFF. THE DEFINITIONS OF HYDROLOGIC DROUGHT, AS USED IN THE US, ARE GIVEN. AGRICULTURALISTS ARE USUALLY CONCERNED WITH SOIL-MOISTURE DEFICIENCIES AS THEY RELATE TO CROP YIELD. SOME INVESTIGATORS CONSIDER THE WATER NEEDS FOR ESTABLISHED HUMAN ACTIVITIES TO BE ESSENTIAL CRITERION FOR DROUGHT CONDITIONS. DROUGHT IS A 'NON-EVENT' OR SITUATION AS OPPOSED TO A DISTINCT EVENT, SUCH AS A FLOOD. UNTIL RECENTLY, MOST OF THE CRITERIA USED TO IDENTIFY DROUGHT HAVE BEEN ARBITRARY AND SUBJECTIVE. METHODS SUCH AS THE PALMER METHOD ARE BEING DEVELOPED TO DEFINE DROUGHT OBJECTIVELY AND CLASSIFY ITS SEVERITY.

A 30-million-lb radial jacking test was made in a gallery of an exploratory tunnel driven into a proposed dam abutment to determine the effects of joints, fractures, and other weaknesses on the deformation characteristics of the rock mass. This paper describes the radial test equipment, instrumentation, and test procedures. A newly developed borehole extensometer was used to measure rock movements at many positions behind the loaded rock surface. This gage could distinguish between closure of joints and elastic deformations of intact rock. Deformations caused by closure of joints and fractures were much greater than those caused by elastic properties of intact rock.

This paper reviews current methods of producing required data on the tunnel site in the preconstruction stage. Consideration is directed toward constructing a free-flow tunnel in fractured rock formations without any requirements for the rock-mechanics type of in situ tests usually made for pressure tunnels or large underground openings. Preliminary office studies, on-site investigations, geophysical surveys, drill holes, exploration excavations, and laboratory tests are discussed. Factors involved in making geologic predictions include physical obstacles and shortage of time and money. Experience indicates present technology is not used fully, and a more realistic allocation of time, money, and qualified personnel is required to achieve the best results. The immediate opportunity for improvement of those results relies more on developing men whose judgment determines the answer and less on developing additional tests for seemingly precise data on minute samples.

THE PURPOSE OF THESE INSTALLATIONS WAS TO OBTAIN STRUCTURAL BEHAVIOR MEASUREMENTS THAT WOULD INDICATE STRESSES AND TEMPERATURES DEVELOPED IN THE LINERS AND REINFORCEMENT DURING OPERATION OF THE PENSTOCKS. MEASUREMENTS WERE MADE DURING A 10-YR PERIOD. STRESSES BASED ON THESE MEASUREMENTS INDICATE THAT 7 TO 30% OF THE TOTAL STATIC HEAD IS RESISTED BY THE LINERS. LINER AND REINFORCEMENT STRESSES VARIED FROM 5-KSI COMPRESSION TO 10-KSI TENSION DURING THE MEASUREMENT PERIOD.

THE REGIONAL GEOLOGY AND STRATIGRAPHY HAVE BEEN STUDIED EXTENSIVELY, BUT LITTLE DATA ARE AVAILABLE ON THE STRATIGRAPHY AND OCCURRENCE OF THE VALLEY FILL. THE UNCONSOLIDATED RECENT ALLUVIUM IS SEVERAL HUNDRED FEET THICK AND COMPOSED OF INTERBEDDED SAND, SILT, AND CLAY. MAIN CAUSES OF SUBSIDENCE INCLUDE: OVERDRAFT OF GROUND WATER, WITHDRAWAL OF CRUDE OIL AND GAS, OXIDATION AND ALTERATION OF PEAT, AND HYDROCOMPACTION. THE FIRST 2 CAUSES ARE MAJOR CONTRIBUTORS TO THE SUBSIDENCE. IRRIGATION OVERDRAFT OF GROUND WATER CANNOT EXPLAIN SUBSIDENCE IN DRY RANGE LANDS SURROUNDING THE VALLEY. SEVERAL OIL AND GAS FIELDS SCATTERED AROUND THE VALLEY ARE PROBABLY RESPONSIBLE FOR THE MINOR SUBSIDENCE IN HILLS. SOME SUBSIDENCE IN THE VALLEY IN AREAS OF OIL FIELDS COULD BE PARTIALLY RELATED TO THE PUMPAGE OF OIL AND GAS. RECENT ACCELERATION OF SUBSIDENCE IN COALINGA, CALIF., INDICATES THAT MOST SUBSIDENCE IS RELATED TO THE OVERDRAFT OF GROUND WATER. COMPARISONS OF 1887 RAILROAD ELEVATIONS WITH 1955 ELEVATIONS INDICATE ABOUT 4.5 FT SUBSIDENCE AT COALINGA AND 7 FT SUBSIDENCE IN THE PASAJERO GAP DURING THAT INTERVAL.

Results apply to Grand Coulee Third Powerplant for 615-mva generators and 500-kv lines, but are of a general nature. Influences of generator rotor losses, saturation and related parameters, transformer and line impedances, and fault phase angles were investigated. Harmonic overvoltage is primarily a function of the generator saliency ratio and line impedances. Generator saturation and losses reduce overvoltages, but saturation may increase overvoltages of generators with intercooling and large amortisseurs. To keep overvoltages within 1.5 and 2.5 per unit, the generator should have normal saturation, a saliency ratio between 1.15 and 1.35, and system design should prevent harmonic resonant line lengths. However, resonance apporached through overspeed of load rejection is not serious. A simplified flow chart is given for the harmonic overvoltage digital program.

As the result of a value engineering study of the problem made by the Bureau of Reclamation, a modified entrance structure was designed. A smaller bellmouth and gate were used based on the premise that entrances for low-velocity penstocks need not be as large as those for high-velocity conduits. Hydraulic model tests were used to prove this concept and develop a design for comparison with an existing conventional design. Estimated savings of $13,000,000 in construction costs will be realized when similar bellmouth, gate, hoist, trashrack, and appurtenant structures are used in the new Grand Coulee Third Powerplant penstock entrances. This powerplant, to be added to the existing Grand Coulee Dam, is planned to contain ultimately twelve 600,000-kw units. Hydraulic model tests, made to confirm general hydraulic concepts and to develop an exact bellmouth shape for the Grand Coulee Third Powerplant, indicated that smaller bellmouths were not only economically desirable but could be designed to perform better hydraulically.

The powerplant, ultimately to be the world's largest, is a major feature of the Bureau of Reclamation's Columbia Basin Project. Also discussed is permanent handling equipment to lift and convey the 2000-ton rotors for the 6000,000-kw generators, the 500-ton turbine runners, and other unusually large and heavy equipment components within the powerplant. Railways can by special routing and in special multiaxle cars, carry loads up to 300 tons, provided clearance requirements can be met. Oversize components will be transported on special trucks or by a combination of barges and special land equipment. An investigation was conducted by the Bureau to determine the adequacy of the bridge spanning the existing spillway to carry loads up to 350 tons. Contractors will be responsible for transporting all equipment and materiels to the construction site without damage to existing facilities.

The effect of cement hydration was isolated by comparing form pressures developed by concrete with a similar but nonhydrating mixture having the same plastic properties as concrete. Oil-filled pressure cells were used to measure form pressures. Tests indicate 3- to 4-in. slump concrete does not behave as a fluid for any appreciable time without some outside energizing force such as vibration. The arching action of aggregate is the earliest factor limiting development of form pressure. Hydration of cement was the next factor to limit form pressure; however, revibration substantially increases form pressure until about 4 hr after placement. The nonhydrating mixtures develop higher form pressures than concrete. Water-reducing, set-retarding admixtures only slightly lower form pressures developed by concrete. The duration, magnitude, and location of the vibratory effort are more important than any other factors considered in development of form pressure and should be consistent with form design. JF - J.

A PRIMARY RESISTANCE INCREASE DEVELOPES RAPIDLY DURING THE FIRST HOURS OF OPERATION AFTER WHICH A SECONDARY RESISTANCE INCREASE OCCURS AT A SLOWER RATE. THE RESISTANCE INCREASES ARE OF GREAT CONCERN BECAUSE OF THE INCREASE IN POWER CONSUMPTION WHICH CONTRIBUTES TO A HIGHER COST FOR PRODUCT WATER. LABORATORY INVESTIGATIONS INDICATED THAT THE MAJOR CAUSE OF THE RESISTANCE INCREASE IS AN ACCUMULATION OF AN IRON-RICH GEL ON MEMBRANE SURFACES. THE GEL WAS OBSERVED CHIEFLY ON THE DIALYSATE SIDE OF CATION MEMBRANES. A HYPOTHETICAL MECHANISM FOR THE FORMATION OF THE IRON-RICH GEL WAS POSTULATED, WHICH INVOLVED THE REACTION OF FERROUS IONS IN THE FEED WATER WITH HYDROXIDE IONS WHICH FORM ON THE DISSOCIATION OF WATER ('WATER SPLITTING'). SULFURIC ACID INJECTED INTO THE DILUTION STREAM ELIMINATED THE SECONDARY RESISTANCE INCREASE WHEN THE PRODUCT ACIDITY WAS LOWERED TO PH 5.1. USING PRODUCT PH 5.5 AS THE BASIS, THE COST OF SULFURIC ACID INJECTION WAS ABOUT 2 CENTS/KGAL./1,000 PPM TDS REMOVED FOR WATER OF DALPRA WELL NO. 1 COMPOSITION. HOWEVER, BECAUSE OF A LOWER OVERALL MEMBRANE STACK ELECTRICAL RESISTANCE, A SAVINGS IN POWER CONSUMPTION OF 2.5 CENTS/KGAL./1,000 PPM TDS REMOVED WAS OBTAINED. ADDITIONAL SAVINGS WILL BE REALIZED THROUGH MORE RELIABLE OPERATION WITH LESS MAINTENANCE AND MEMBRANE REPLACEMENT.

OF THE 112 FIELD SAMPLES EVALUATED FROM 20 DIFFERENT CANAL INSTALLATIONS, MORE THAN 80 PERCENT DEMONSTRATED SATISFACTORY RESISTANCE TO FIELD AGING. THE MEMBRANES IN POOR CONDITION RESULTED FROM ACCELERATED AGING PRIMARILY DUE TO DEFECTIVE CONSTRUCTION PRACTICE. TEST RESULTS INDICATED THAT THICKNESS IS ONE OF THE MORE IMPORTANT FACTORS CONTRIBUTING TO LIFE OF THE ASPHALT MEMBRANE. FOR A MAJORITY OF THE MEMBRANES EVALUATED, THE CHANGE IN PHYSICAL PROPERTIES DUE TO FIELD AGING DID NOT MATERIALLY AFFECT THEIR ABILITY TO PROVIDE A FLEXIBLE, WATERTIGHT LINING. TESTS INDICATED THAT THE GREATEST PORTION OF THIS CHANGE OCCURS DURING THE FIRST 6 YEARS OF SERVICE. AFTER THIS PERIOD, THE RATE OF CHANGE IS SLOWER. AN AGING INDEX WAS CALCULATED THROUGH A COMPUTER PROGRAM TO DETERMINE THE RELATIVE CHANGE IN THE PHYSICAL PROPERTIES OF THE MEMBRANE. THIS STUDY REAFFIRMS THE POINT THAT ADEQUATE SEEPAGE CONTROL WILL BE MAINTAINED FOR MANY YEARS IF THE MEMBRANE IS INSTALLED IN ACCORDANCE WITH CURRENT SPECIFICATIONS.

THE RESERVOIR SITES ARE LOCATED IN PLEISTOCENE-EOLIAN DEPOSITS IN CENTRAL AND WESTERN NEB AND KANS AND NORTHEASTERN COLO. INITIAL PESSIMISM ON THE FEASIBILITY OF CONSERVATION RESERVOIRS IN PERMEABLE CONTINENTAL SEDIMENTS OF THE LOESS AND SAND DUNE REGION HAS CHANGED TO CAUTIOUS OPTIMISM THROUGH KNOWLEDGE GAINED FROM CONSTRUCTION AND SUCCESSFUL OPERATION OF MANY RESERVOIRS. LOESS AND DUNE SANDS ARE MODERATELY PERMEABLE BUT DO NOT PRESENT MAJOR LEAKAGE PROBLEMS. SEEPAGE OCCURS MAINLY THROUGH PLEISTOCENE ALLUVIAL SANDS AND GRAVELS AND THROUGH ZONES OF UNCEMENTED SANDY BEDS IN THE OGALLALA FORMATION. TREATMENT CONFINED TO THE AREA OF THE DAM AND ADJACENT PARTS OF ABUTMENTS AND CHANNEL HAS BEEN SUFFICIENT TO CONTROL LOSSES TO ACCEPTABLE AMOUNTS. CUTOFFS AND BLANKETS OF IMPERMEABLE MATERIAL FROM REQUIRED EXCAVATION HAVE BEEN USED SUCCESSFULLY TO REDUCE SEEPAGE. THOROUGH DRAINAGE AT THE TOE OF THE DAM IS NECESSARY; ADDITIONAL DRAINAGE BY DITCHES OR RELIEF WELLS IS NEEDED AFTER THE RESERVOIR STARTS FILLING WHEN REQUIREMENTS CAN BE PROPERLY DETERMINED. SEEPAGE LOSSES HAVE NOT IMPAIRED THE PLANNED OPERATION OF THE PROJECTS.

Two types of aquifers were studied: (1) a 1:40 scale, two-part aquifer (coarse and find sand) representing a vertical cross section through an idealized portion of an irrigated valley; and (2) a fine sand, single-part aquifer used to evalute a formula derived from the Ghyben-Herzberg principle for computing depth to a saline-fresh water interface. Salt water was flushed from the aquifers into subsurface drains by applying fresh water to the surface. Test results for both aquifer types showed that tile drains placed near the ground surface will not intercept and discharge surface-applied fresh water if all or part of the aquifer contains salt water. The fresh water displaces the salt water without appreciable mixing and moves it into the drains forming a stable fresh water-salt water interface. Reducing the spacing of drains reduces the amount of salt water that will be removed from the aquifer. The aquifers were charged with salt water having sodium chloride concentrations of 4,000 to 79, 770 ppm and colored blue for visual identification. Progress of the tests was recorded in still- and timed-sequence motion pictures. JF - Bur Reclam Res Rep No 13, 1968. 42 p, 49 fig, 2 tab, 11 ref.

Purpose of the installation was to obtain structural behavior measurements for information on the amount of total static head resisted by steel liners. Three strain meters and 2 pressure meters were installed at 6 tunnel stations. Installation of these meters and interpretation of test results are discussed. Measurements were made over a 5-year period. Results indicated one-fifth of the total head was resisted by the liners and permanent stress changes were not produced in the liners from backfill grouting. Exterior surfaces of some liners were subjected to hydrostatic pressures produced by ground water or by water leaking from the conduit. Measurements taken after placing backfill concrete showed that compressive stresses developed in the liner before the conduit was filled. Additional measurements will be required before an explanation can be given for the conditions producing initial compressive stresses in the liner.

Results indicate that sustained compressive modulus of elasticity and creep of concrete, after any particular period of constant load, can be predicted easily from the intial modulus value at load application and fixed R-line relationships. An R-line represents graphically the relationship between initial secant modulus and sustained secant modulus of loaded concrete. The effects of many variables on R-lines are reported and discussed. Some of these are: intensity and zolans and admixtures; age of concrete; moisture conditions; removal of stress; uneven stress; and temperature. Moduli relations for some epoxy resin mortars and concretes and some rock materials under sustained compressive loads are discussed. JF - Advance Manage J, Vol 33, No 1, pp 56-62, Jan 1968. 7 p.

Creep, compressive strength, and modulus of elasticity were measured on concrete dried at temperatures of 73, 130, 180, 230, and 290 deg F over a period of 6 mo. Results show creep at 290 deg F is about 5 times the creep at 73 deg F. Compressive strength is lowest at 180 deg F; elastic modulus is lowest at 230 deg F and about one-half the modulus at 73 deg F. Variations in concrete properties indicate that possible changes in the composition of concrete occur at temperatures above 180 deg F. Data on strength and moduli changes during storage, strain of unloaded concrete specimens, and weight loss at the different temperatures are reported.

Elastic-plastic strain energy, derivable from an engineering stress-strain curve, is proposed as a new parameter. The proposed parameter is shown to correlate well with observed cavitation resistance of the alloys tested. The total strain energy concept is shown to conform with experimental observations of: (1) critical wave energy or threshold velocity concept, (2) ordering of observed cavitation resistance of the alloys, (3) accelerated cavitation damage observed on some alloys in cavitation environments, and (4) varying ratio between the cavitation resistance of some alloys when exposed to different cavitation wave energies.

Complete results are reported from investigations started in 1951. Fifty-eight materials were evaluated for resistance to stresses developed by wetting and drying of clay soils and to puncturing from hard clods and rocks. Exposure conditions were simulated by the soil stress test, subjecting specimens buried in a clay soil to wetting and drying conditions. Resistance to puncturing was measured by an indentation test. Fifteen protective coating systems offered good resistance to soil stresses and indentation. JF - Bur Reclam Lab Rep ChE-64, Chem Eng Br, Nov 1967. 76 p, 62 fig, 3 tab, 3 ref, append.

A vertical slide gate device (baffle gate) was developed for cleaning the gravel spawning bed of the canal. The gate can be moved along the length of the canal and positioned in the water to produce a jet of higher velocity flow beneath the gate. A secondary use of the baffle gate is to provide a 50-fps velocity barrier for controlling movements of small fish in the canal. Model tests were made to determine whether this velocity barrier could be maintained without eroding the gravel bed and to determine baffle gate settings to produce the 5-fps velocity barrier for given discharges. A photograph and drawing of the model flume, test data, and a gradation curve of model gravel are included. JF - Bur Reclam Lab Rep Hyd-579, Hydraul Br, Nov 1967. 26 p, 14 fig, 4 tab, 1 ref.

The effect of filling Lake Powell on the water quality of Lake Mean is evaluated. General limnological principles and the present limnology of Lake Mean are discussed. Lake Mead has a warm monomictic annual temperature cycle characterized by spring overturn, summer stratification, and continuous circulation throughout the winter; temperatures never fall below 39 deg F (4 deg C). During Stratification, lower dissolved oxygen values were recorded in the thermocline than in the epilimnion. Mineral content increased from the upper to the lower end of Lake Mead; the greatest increase is in calcium and sodium sulfates and chlorides, although there is an overall decrease in bicarbonate. Filling of Lake Powell intensified the deterioration of water quality in Lake Mean during 1965, as evidenced by increased temperature, conductivity, and total disolved solids and decreased dissolved oxygen. Las Vegas Bay reach was found to be a major source for degradation of water quality in Lake Mead because of its large input of dissolved salts and algae nutrients. The monitoring station at Hoover Dam has been a useful indicator of water quality in the lower reach of Boulder Basin.

BECAUSE OF A FAILURE OF THE BOLTED CONNECTION OF A RUNNER TO A TURBINE SHAFT, THE LENINGRAD METALWORKS DEVISED TEST PROCEDURES AND EQUIPMENT TO INVESTIGATE THE RELAXATION OF THE INITIAL STRESSES IN BOLTED CONNECTIONS OF HYDRAULIC UNITS. THE EQUIPMENT AND PROCEDURES ARE DESCRIBED AND GRAPHS SHOWING THE RESULTS OF THE TESTS ARE GIVEN. CONCLUSIONS ARE: (1) RELAXATION OF INITIAL STRESSES IN THE BOLTS IS MAINLY DUE TO RESIDUAL STRESSES IN THE THREADS GROWING IN PROPORTION TO THE NUMBER OF CYCLES OF CHANGES IN LIVE LOAD. (2) DEGREE OF RELAXATION IS REDUCED IN PROPORTION TO THE INCREASE IN INITIAL TORQUE. (3) THE BASIC CAUSE OF THE FAILURE INVESTIGATED WAS INSUFFICIENT TORQUE OF THE BOLTS, WHICH LEAD TO INTENSIVE RELAXATION OF THE INITIAL STRESSES CORRESPONDING TO AN INCREASE IN THE ADDITIONAL STRESSES DUE TO THE ACTION OF EXTERNAL LOADS AND FINALLY TO FATIGUE.

The resulting augmented spring runoff, regulated by existing reservoirs, can provide additional water to meet growing demands for the region where present water supplies are becoming critically short. Increasing the November through April precipitation by 15% over 14,200 sq mi of target areas generally located at elevations above 9500 ft will yield an average additional runoff of 1,870,000 acre-ft annually. This practical capability to enhance the winter snowfall should be developed by the mid-1970's through the $25 million applied research field program outlined in the paper. Exclusive of initial research costs, regular production costs by weather modification are estimated at $1.00 to $1.50 an acre-ft for the new water. Average additional benefits are estimated to be $20 to $25 million annually for a highly favorable benefit-cost ratio of about 10 to 1.

The deformation was caused by seasonal temperature variations, long-term gradual warming of concrete, and loading imposed by impounded reservoir water. Two measurement systems were used: first-order triangulation surveys and plumbline measurements. The measurement systems, field programs, apparatus, observation practices, and procedures adopted to increase efficiency and accuracy are described; representative results are given. Each year, the top of the dam moves about one-half in. during a 60-deg temperature range. The total deformation from the initial measurements to the maximum temperature period in 1966 was about 1-1/2 in. upstream. Surveying methods offer a convenient and reasonably accurate means for measuring dam deformation. More than 1 baseline is recommended in a behavior triangulation net. The time-consuming procedure of turning angles for precise triangulation could be supplemented by using presently available electronic distance measuring devices to reduce the cost and time involved. With these devices, all measured lengths in the control net would be comparable to computed baselines. Experiences indicate dam measurements should be initiated during either the high- or low-temperature period. JF - Paper, ASCE Ann Mgt & Water Resrcs Conf, New York, N Y Oct 1967.

Canal capacity, particularly in concrete-lined sections, can be reduced significantly by this growth. The Madera Canal capacity was reduced by 29% when algae was allowed to grow unchecked. In a large canal such as the Friant-Kern a loss of 10% of capacity amounted to 900 acre ft/day. Furthermore, with algae conditions present, developing an accurate stage-discharge relationship in the canals for measurement purposes is impossible. Of several different soil sterilants and methods tried, the most successful was dumping fine copper sulfate crystals into the flowing water. Satisfactory algae control was obtained with only 1 lb of crystals per cfs in the Friant-Kern Canal and 2 lb/cfs in the Madera. A description of the successful technique used and breakdown of costs are given. JF - Paper, ASCE Water Resrcs Conf, New York, N Y, Oct 1967. 25 p, 5 fig, 6 photo, 1 tab.

With a maximum designed capacity of 183 cfs, the system has pipe vaying from 96- to 10-in.-id with hydrostatic design heads of 25 to 500 ft. The terrrain varies from steep, abrupt, eroded badlands, to relatively flat cultivated land. Conventional methods of pipelaying were abandoned by the contractor after the 1st month, and more efficient and economical procedures were devised. Traveling cradle-cutting machines were developed which excavated the cradle 2 in. below pipe bottom grade. Plastic soil-cement was used for filling the 2-in. space under the pipe. Among other innovations were bell excavating machines attached to power takeoffs of farm tractors. The new pipelaying procedures reduced initial costs by approximately 30%.

PRELIMINARY DATA SHOW THAT THE MOST COMMON CAUSE OF LOWER THAN OPTIMUM IRRIGATION EFFICIENCIES, AFTER DIFFERENCES OF SOIL TYPE, SLOPE, AND CLIMATE HAVE BEEN ELIMINATED, IS LACK OF SUFFICIENT INFORMATION ON THE PART OF THE IRRIGATOR ABOUT WHEN TO APPLY WATER AND HOW MUCH TO PUT ON. FARM EFFICIENCIES HAVE A GREAT EFFECT ON WATER PROJECTS. FOR EXAMPLE, A CHANGE FROM 50% TO 60% FARM IRRIGATION EFFICIENCY WOULD RESULT IN A 17% REDUCTION IN WATER REQUIREMENT FOR THE AREA OR A 20% INCREASE IN THE AREA WHICH SOULD BE SERVED. THIS DOES NOT TAKE INTO ACCOUNT ANY DOWNSTREAM REUSE OF RETURN FLOW, BUT IT POINTS OUT THAT IN SOME AREAS IMPROVED EFFICIENCE OF USE OF PRESENT WATER SUPPLIES MAY BE MORE ATTRACTIVE IN TERMS OF COSTS AND BENEFITS THAN DEVELOPMENT OF NEW SUPPLIES.

Surges developed when the downstream portion of the check structures did not flow full. The surges were initiated by releasing air entrained in the downstream leg of the check structures, and were amplified as the flow passed through the successive pipe reaches. The experiments were made of various inflows steady at the upstream end of the system. Plots of surge magnitude against inflow rate showed 2 peaks. One peak resulted from surges initiated by air release through the vent downstream of the check structures; the other peak originated from surges initiated by air release through the downstream leg of the check structure. The nonlinear momentum equation was integrated numerically to predict the growth of the discharge surge from 1 pipe reach to the next. Results were in good agreement with the experiments for different head loss conditions and for pipe reaches with and without surge tanks.

The minimum cost distribution system will deliver just enough water to meet peak demands with sprinklers operating almost continuously. An equation is developed to determine cost differential between this minimum capacity system and one using large pipe to allow part-time sprinkling. A method for economic sizing of pipe in a gravity system is developed and its use illustrated; an economic sizing method for pump discharge lines with lateral turnouts is developed also. Use of graduated-size pumps is recommended to provide greatest flexibility in operation with a reasonable number of units.

At 2 large dams, concrete-lined spillway tunnels used for river diversion during construction suffered extensive erosion from river gravel and construction debris churned in the turbulent hydraulic jump. Rock debris fallen or thrown into a spillway hydraulic jump stilling basin caused extensive erosion of the floor, walls, and dentates. An example is cited of serious cavitation damage to concrete surfaces in hydraulic jump outlet stilling basins caused by improperly installed outlet gates and poor workmanship. At 3 projects, erosion and structural problems were encountered with high-efficiency hollow-jet valve stilling basins. Channel riprap was dislodged and conveyed by reverse roller action into the basin, devastating the basin floor and walls. The intense turbulence in hollow-jet valve basins imposes high dynamic forces on divider walls, producing high bending moments and vibrations approaching a resonance condition. The knowledge gained from these experiences had led to changes in design and construction procedures for stilling basins. Techniques for corrective and preventive maintenance are discussed.

Measurements were made in the Salt River Project irrigation system in concrete pipelines 2, 2.5, and 3.5 ft in dia. A pitot velocity method was used to measure the discharge for comparison with the discharge measured by the sudden injection or total count radioisotope method. The sample tank and infinite medium techniques were used for counting the radioisotope acticity. Accuracy of the radioisotope measurement method could not be evaluated extensively because of the limited number of tests. Although relatively good repeatability was shown in measuring a given discharge by the radioisotope method, discharges computed by the 2 methods differed by -7.3 to -15.7%.

All criteria and instructions for operation and maintenance of each dam are being assembled in a volume containing: (1) administrative procedures for reporting, decision making, and coordinating with other agencies; (2) detailed information and instructions on the operation and maintenance of the dam and related facilities; and (3) reservoir operating criteria including storage allocations, filling and release procedures, hydrologic forecasting, and flood opeating criteria. Maintanance at each dam is reviewed by project supervisors and engineers periodically. A program is in progress to review flood hydrology for older dams to determine adequacy of spillways. Consideration is given to geologic and seismic conditions and possible alkali-aggregate reaction in concrete at older structures. The competence of dams designed and constructed by local interests above Reclamation dams is being cooperatively reviewed. Reclamation is urging Federal legislation to assist in preventing and correcting dangerous conditions at all storage dams.

Drainage was achieved by pumping ground water from 100 wells and moving it out of the area by way of a 73-mi-long concrete lined conveyance channel. In March 1962, when the first Depth to Ground-water map was prepared, almost 26,000 acres of the 60,000 acres of land in the valley had a depth to ground water of 8 ft or less. By March 1964, the area with a 8 ft or less water table had been reduced to 7250 acres. The discharge from drainage wells was salty and caused a salinity problem with Mexico. This was solved when a bypass channel around Morelos Dam, Mexico's principal point of diversion on the Colorado River was placed in operation. Other factors, such as floodflows in the Gila River, have complicated the ground water and salinity control measures. The presence of bacteria in the wells has led to the use of corrosion-resistant materials for construction.

The leakage path was found to be through the abutment, although the first impression was that it was through the dam or along the contact. Emergency measures consisted of opening the main outlet which had been closed for minor repair and opening outlets on both abutments leading to canal systems that had not been constructed. The prompt action lowered the reservoir before erosion from the flow could cause a breakthrough. The difficulty occurred on first filling of the reservoir, unusually rapid because of extremely large inflows. Repairs consisted of thorough grouting of the foundation and restoration of the embankment damaged by the sudden flow. The experience illustrates the need for slow, controlled filling of reservoirs where unfavorable foundation conditions are known to exist. Foundation conditions, design, and construction practices are examined to determine why this situation developed despite the precautions taken in the original design and construction because of known unfavorable geologic conditions. Modifications needed to prevent a recurrence at this dam and other simialar sites are discussed.

Pilot studies into the use of electronic equipment in the analysis of random pressure fluctuations in models of 2 distinct types of stilling basins are described. The models investigated represented Morrow Point Dam with a free-fall spillway with impact-type energy absorbing pool at the base of the dam and Crystal Dam outlet works having a hydraulic jump stilling basin with a center wall separating the jets from 2 high-pressure slide gates. Data from the 2 models showed marked differences in the frequency spectra. The studies were restricted to determining dynamic loads acting on the structures, without regard to the dynamic response of the structures. The analyses described allow solution to 2 problems encountered in the design of hydraulic structures: (1) determination of stresses caused by the application of a periodic force at a given frequency, such as the natural frequency of the structure; and (2) determination of stresses resulting from the complete spectrum of forces and frequencies under nonresonant conditions.

This study is concerned with cleaning deposited sediment from the 2.5-ft-deep gravel spawning bed in the dual-purpose channel and related problems. Exploratory tests were made in a 2- x 2- x 8-ft-long flume to determine which of various possible cleaning methods might be successful. These preliminary tests considered underdrains, water and air jets, a floating barge with and without underwater baffles, a mechanical cleaning device, and a baffle gate by which the sediment was washed from the gravel as the gravel was moved a short distance downstream. Based on these tests, the baffle gate method was studied in detail in a larger flume 4 ft wide, 8 ft deep, and 80 ft long. Tests were made with prototype-size gravel (3/4 to 6 in) up to the depth and discharge capacity of the flume. To test the full prototype depth, gravel sizes were reduced to a 1:2 scale. Depth that the gravel would be scoured was related to 2 variables: position of the baffle gate above the gravel and differential head across the gate. Requirements for successful spawning by salmon are discussed and hydraulic design criteria for the facility are included.

The engineer must consider earthquakes in his design and provide sufficient resistance to this phenomenon. Three major problems are encountered when selecting design criteria for concrete dams subjected to earthquake: (1) a method for analyzing the dynamic response of the structure and the resulting loads, (2) a definition of structural failure under seismic loads, and (3) selection of criteria based on these items. Based on the premise that concrete dams are elastic structures and can be excited to resonance by earthquakes, a method is presented for determining dynamic loads and computing the resulting stresses. The earthquake response spectrum concept is used, and hydrodynamic effects, structural damping, and dynamic response of the dam are included. Results of a controlled vibration test are compared with estimated dynamic properties for one arch dam. The possiblility and degree of structural failure are investigated because of the development of relatively large stresses from dynamic loading. Design criteria are proposed, based on compressive strength of concrete as the most important measure of the strength of the dam.

FOR MOMENT AND HORIZONTAL FORCES WHERE THE SPIRAL ATTACHES TO THE SPEED RING, THE LATTER CAN BE CONSIDERED AS A RIGID TORUS-SHAPED SHELL OR, FOR WELDED SPIRAL CASES, AN IMAGINARY CONICAL SHELL CAN BE SUBSTITUTED AND EQUATIONS FOR DEFORMATION OF CONICAL SHELLS USED. FOR COMPUTING DIFFERENT TYPES OF RIBBING DEPENDING ON STRESS DISTRIBUTION, CHANGE OF MOMENT, AND BOUNDARY STRESSES. EXPERIMENTS SHOW THAT STRESSES ARE DISTRIBUTED VERY UNEVENLY IN EACH SECTION, THE GREATEST BEING WHERE THE SPIRAL IS JOINED TO THE SPEED RING BANDS.

After 3 yr of observing these test sections, the following conclusions were drawn: (1) Steel jacks are more effective in arresting bank erosion than piling and fencing. Jacks were installed for about $3.40 per lin ft, whereas piling and fence are much more costly. (2) Minimum radius for jack alinement should be about 50 ft. (3) The rate at which a line of jacks can develop efficient sediment deposit to form a new stailized bank line depends primarily on the trapped debris, sediment carried by the stream, and reduction in stream velocity behind the jacks. (4) The best position for individual jacks is such that one axis of the jack is on a plane 10 to 50 deg downstream from a line normal to streamflow. (5) Bank stabilization can be expedited by sloping the bank behind the jacks, allowing vegetation to get an early start; also, sediment deposit can be accelerated by placing trees and brush between the jacks and bank. (6) Use of retard lines should be limited to locations where a wide area of sediment deposit is desired. (7) Generally, jacks should be placed close to the existing bank in areas of clear water. (8) Placing double rows of parallel jacks is normally of little advantage. JF - ASCE Proc, Jour Wtrwys & Hbrs, Vol 93, No WW3, paper 5396, pp 89-108, Aug 1967. 20 p, 25 fig.

With this means of structural analysis, design of rock structures can be resolved into the familiar pattern applied to any structure, but somewhat different procedures and parameters are involved. The method includes the following steops: (1) isolate an appropriate geostructural block containing the opening or excavation from the rock mass for structural analysis; (2) determine the geology of the geostructural block; (3) determine forces acting upon and within the geostructural block; (4) determine mechanical properties of rock; (5) determine stress distribution within the geostructural unit; (6) determine if failure conditions exist; and (7) if collapse conditions exist, determine structural support required to stabilize openings. Each of the steps is discussed and 2 examples (an underground opening and a cut slope) of structural analysis of rock using this method are given.

Physical processes in frictional sliding and effects of surface roughness and confining pressure on the coefficient of friction are reported. Changes in friction with displacement, load dependence of friction, and effects of water are discussed. At high confining pressures, fricition between ground surfaces of granite reaches a maximum value after 0.1 cm displacement and then decreases to a nearly constant value after sliding 0.5 cm. This maximum value is nearly the same as the initial value for perfectly mated rough surfaces. Decrease in friction is probably caused by rolling on wear particles. Under increasing confining pressures, friction decreases with increases in normal stress. Sliding movements occur with violent stick-slip and appear to be controlled by brittle fracture. Test results on granite are not in agreement with the Coulomb theory of rock fracture but are consistent with the effective stress theory as applied to friction.

The site was investigated by the Bureau of Reclamation from 1961 to 1964 to delimit the contact of evaporite and carbonate facies, establish that the carbonate rocks were a ground water barrier, and determine the site's acceptability as a suitable reservoir basin and damsite. Techniques included coring, percolation tests, water sampling, electric and gamma ray logging, and water table measurements. The rocks form a gently dipping homocline disrupted in places by hydration and solution of evaporites. Karstic terrain prevails in much of the area. The reservoir, on cavernous evaporite and pervious breccia, abuts tight carbonate rocks down-dip. Ground water conditions are favorable, leakage will be small, no deep percolation is foreseen, and conservation storage is practical. Brantley damsite on carbonate rocks was determined to be sound.

The embankment was raised in 3 stages to 35 ft above original ground surface, permitting strength increase in the foundation between each stage. Strength increase was measured by means of the Bureau of Reclamation field vane test. These tests indicated that the measured strenth increased concurrently with consolidation and drainage of the subsurface strata and that the variation of the maximum vane shear strength, vertically and horizontally beneath the embankment, coincided with a computed embankment vertical stress distribution. Strength increases as much as twice the initial values were measured beneath the center of the embankment. Preconstruction investigations and studies during construction are discussed, foundation conditions are described, and field vane test procedures and results are presented.

Such logging can be used to determine quantitatively the density of the rock and its lithology and porosity. The scattered gamma radiation is a function of several parameters: (1) rock density, (2) density of the drill hole fluid, (3) radius of the drill hole, (4) shielding of the iron jacket of the gamma ray detecting device used in the drill hole, and (5) distance between the gamma ray source and the detector. The relationship between the gamma ray intensity and the density of the rock is determined by a diffusion equation for the absorbing medium. This equation and other equations required a presented and discussed in detail. JF - Bur Transl 710, July 1967. 17 p, 2 fig, 7 ref.

This was shown by measurements taken during construction of the San Luis Pumping-Generating Plant. The installation of 8 units afforded an opportunity to study the effects of varying amounts of cooling water circulation. Concrete temperature increases resulting from heat of hydration of the cement were recorded, as were deformations to head cover seats and lower stationary wearing rings. No correlation could be distinguished between increased temperatures in the concrete and measured pump-turbine component deformations.

A concrete-lined section between Friant Dam and Mile 29 and an earth-lined section between Mile 35 and Mile 53 served as the test reaches. Eight radioisotope injections were made, resulting in 24 individual discharge rate determinations. The discharge values obtained with the radioisotope measurements ranged from 2643 to 3128 cfs and were compared to the results of current meter measurements and the discharges indicated by calibrated hollow-jet valves at Friant Dam. Measurement accuracies based on the above comparison were all within 9.5%, but many were within 2%. The integrated sample and total count methods were used to determine the discharge with radioisotopes. A water proof scintillation counter and 2 Geiger counters were used in the tests. New methods of field calibration of the immersed counter were tested successfully to calibrate the scintillation counter.

Formerly, water quality sampling programs consisted chiefly of collecting spot samples at selected sites in an area of study. Such samples, taken on a monthly, weekly, or even a daily basis, show general long-term trends in water quality but fail to show short-term fluctuations. Diurnal variations in quality can be caused by biological activity and sunlight and air temperature variations. Other cyclic fluctuations can be caused by changing weather conditions, sporadic discharge of sewage and industrial effluent, and tide stage in areas subject to tidal influence. The paper describes several automatic monitoring instruments and discusses their use in the water quality management program of the Bureau of Reclamation in Region 2.

These applications include asphalt canal linings, asphaltic concrete dam facings, plastic canal linings, plastic cutoff curtains, plastic pipe, and chemical soil sealants. A summary of different types and costs of canal linings installed on Bureau projects is given. Average installation costs of bituminous linings range from $1.50 to $3.00/sq yd for asphaltic concrete, $1.35 to $1.75/sq yd for prefabricated asphalt membrane, and $0.90 to $1.10/sq yd for buried asphalt membrane. The most promising plastic canal lining appears to be polyvinyl-chloride; over 127,000 sq yd of buried 10-mil-thick-polyvinylchloride membrane have been installed at a cost as low as $0.75/sq yd. Design and construction of hot-mix asphaltic concrete dam facings for Bonny Dam, Colo; Glen Anne Dam, Calif; and Montgomery Dam, Colo, are discussed. Laboratory and field investigations of chemical soil sealants are somewhat encouraging although no material thus far has met completely all requirements satisfactorily.

Lancelets were collected with a sand dredge and Campbell grab from North Carolina to Florida. Concentrations of lancelets were found south of Cape Hatteras. There is a 2 to 18 km wide belt that is rich in lancelets extending from Charleston, South Carolina, to at least Cape Kennedy, Florida. The largest numbers are off South Carolina and Georgia, where population densities reach 200/m super(2) (Campbell grab) or 57/liter (sand dredge). Most specimens were taken from coarse, shelly, siliceous sand. A few were occasionally collected from finer sands, but none from silt. Most were taken from depths between 10 and 30 m.

CALCULATING AND TEST WORK IN THIS FIELD HAVE ESTABLISHED THE FACT THAT THE RUNNER BAND VIBRATES EITHER AS A RING OR IS DISPLACED AS A SOLID BODY DURING VIBRATION OF THE RUNNER SYSTEM. ALTERNATION OF VIBRATIONAL FREQUENCIES AND MODES IS INVOLVED LATER IN THE ACTUAL DESIGN OF THE RUNNER; SO, AT THIS STAGE, CONSIDERING THAT THE BAND VIBRATES AS A RING AND THE MASS OF BLADES DOES NOT SUBSTANTIALLY AFFECT THE FREQUENCY, IT IS SATISFACTORY TO ASSUME THAT WHEN THE NUMBER OF BLADES IS LARGE, THE ACTION ON THE BAND CAN SUBSTITUTE FOR THE ACTION ON ANY EQUIVALENT ELASTIC FOUNDATION. THUS, THE PROBLEM IS REDUCED TO AN EXAMINATION OF VIBRATIONS OF A RING ON AN ELASTIC FOUNDATION. THIS IS VALID ONLY FOR THE SEVERAL PRIMARY MODES. SAMPLE CALCULATIONS ARE GIVEN, THE RESULTS OF WHICH COMPARE FAVORABLY WITH TEST VALUES OF FREQUENCIES. JF - AVAILABLE FROM NTIS AS PB-193 631T, $3.00 IN PAPER COPY, $0.95 IN MICROFICHE.

Particular attention is directed to the growth, form, and collapse of the vapor cavity in a horizontal pipe of small diameter. Column separation is described and investigated in terms of governing fluid dynamics. Partial differential equations of continuity and momentum, including nonlinear friction losses, are used to mathematically represent the transient movement of liquids in full and partially full pipes. Systems of equations are programmed for numerical simulation of the column-separation phenomenon, using a digital computer and the method of characteristics. Theoretical time-pressure information derived from mathematical simulation is compared with the corresponding experimental information obtained from laboratory investigation. Despite higher-than-anticipated energy losses in the prototype flow, the general comparison of the 2 sets of information is favorable.

These measurements were interpreted to obtain seismic velocity and electrical resistivity of rock behind the disturbed rock surrounding the pilot bore. Velocity and electrical resistivity were found to have quite good correlation with time rate of construction, construction cost per foot, rock quality, set spacing, percentage lagging and blocking, type of steel support required, height of tension arch, and vertical load. Results indicate that predictions of engineering and economic parameters could be made for a new tunnel if correlations such as these could be established either during the initial stages of construction or from pervious measurements of another similar tunnel constructed in similar rock. Additional seismic and resistivity surveys were made on the surface and in holes drilled from the surface over the line of the pilot bore. Reasonably accurate predictions are possible from surface measurements and would be useful for selecting a site if several alternative routes were under consideration. With an established predictive capability, tunneling efficiency can be improved and costly pilot bore construction probably could be eliminated.

Data can be obtained on source, velocity, and chemical quality of ground water; location, extent, geometry, bulk density, porosity, permeability, and specific yield of aquifers and associated strata; and position of casings, casing collars, leaks, perforations, and cement. The radiation logs employed include natural gamma, gamma-gamma, neutron-gamma, neutron epithermal-neutron, and radioactive tracer. Radioisotopes used were cobalt-60, plutonium-239, americium-241, and iodine-131. Typical radiation logs obtained by various techniques are described and examples given of applications of radiation logging to ground water investigations. Applications cited are studies of perched water in basaltic rocks and associated sedimentary strata; porosity, moisture content, and position of zones into which water was injected in volcanic tuff; position of the interface between brine and fresh water in fine-grained carbonate rocks and associated fine clastic rocks; interpretation of porosity from a neutron log; and location by means of a radioactive tracer of the more permeable fracture zones in a well penetrating crystalline rock.

UNDER SIMILAR SOIL CONDITIONS BUT WITH DIFFERENT FREEZING DEPTH, THE RATIONAL SOLUTIONS OF THIS PROBLEM MAY DIFFER. FOR WATER-PERMEABLE NONCOHERENT SOIL CONDITIONS THE RELATIONSHIP BETWEEN THE DEPTH OF THE DRAINS AND THE DISTANCE BETWEEN THEM IS SUFFICIENTLY WELL ESTABLISHED, AND AMONG THE SPECIALISTS NO DIFFERENCES OF OPINION EXIST ON THE PROBLEM OF THE OPTIMUM DRAIN DEPTH. HOWEVER, THERE ARE DIFFERENT OPINIONS ON THE DEPTH AT WHICH A DRAIN SHOULD BE PLACED IN CLAYEY SOILS AND GROUND. THE QUESTION OF THE NECESSARY DEPTH FOR DRAINS IN CLAYEY LOAM AND CLAYEY SOIL-GROUND IS EXAMINED. JF - TRANSLATED FROM: GIDROTEKHNIKA I MELIORATSIYA VOL 18, NO 6, P 44-51, 1966.

THE RUNNERS WERE LOADED ONE AT A TIME AT THE LMZ PIER FROM RAILROAD TRANSPORT FLATCARS TO A LIGHTER. AT THE LENINGRAD COMMERCIAL SEAPORT THEY WERE UNLOADED BY THE HARBOR FACILITIES AND THEN RELOADED TOGETHER WITH TWO GENERATOR THRUST BEARING TANKS INTO THE HOLD OF A SINGLE SEA-GOING BARGE. THE ROUTE WAS THROUGH THE WHITE SEA-BALTIC SEAWAY, CONTAINING NUMEROUS, RELATIVELY SMALL, ONE- OR TWO-CHAMBERED LOCKS, WHERE THE HELP OF TUGS AND WARPING HAWSERS WAS NEEDED TO LOCK THE BARGE. THROUGH THE NORTHERN SEAWAY ALONG THE COAST OF THE ARCTIC OCEAN, FOGS, ICEPACKS, AND STORMY WEATHER WERE ENCOUNTERED, BUT THE METHOD OF LOADING AND LASHING THE RUNNERS PROVED TO BE SATISFACTORY. THE ENISEI RIVER HAS MANY RAPIDS AND SANDBARS FROM ITS MOUTH TO THE UNLOADING POINT AT DIVNOGORSK. THESE REQUIRED THE HELP OF SPECIAL LOCAL TUGS AND A RIVER PILOT. DOCKING AND UNLOADING THE RUNNERS EACH REQUIRED LESS THAN 24 HOURS TO ACCOMPLISH. SUCCESS IN HANDLING THESE LOADS CONFIRMS THE POSSIBILITY OF HANDLING AND TRANSPORTING THE RUNNERS FOR THE ASWAN HIGH DAM TURBINES TO THE UAR IN THE SAME WAY.

NEW METHODS INTRODUCED BY USSR HYDROTURBINE MANUFACTURERS FOR CALCULATING SHAFT STABILITY SHOULD CONSIDER THE GENERATOR NOT ONLY AS A CONCENTRATED MASS BUT ALSO FOR THE ELECTROMAGNETIC FIELD IT CREATES. THIS LEADS TO NEW PHENOMENA, ESPECIALLY IN DETERMINING CRITICAL SPEEDS FOR TRANSVERSE VIBRATIONS. AN EQUIVALENT MECHANICAL SYSTEM WITH PARAMETERS DEPENDING ON CHARACTERISTICS OF GENERATOR WINDINGS AND OPERATING CONDITIONS CAN BE SUBSTITUTED FOR THE ELECTROMAGNETIC FIELD IN DETERMINING NATURAL FREQUENCIES OF TORSIONAL VIBRATIONS. SOLVING THE DIFFERENTIAL EQUATIONS SHOWS THAT ELECTROMECHANICAL VIBRATION FREQUENCY IS FROM 0.5-2.5 CPS, INDICATING THAT CALCULATION OF THESE VALUES IS OBLIGATORY TO CONSTRUCT A FULL FREQUENCY SPECTRUM. FOR TRANSVERSE VIBRATIONS, A 1-SIDED ELECTROMAGNETIC PULL BETWEEN THE ROTOR AND STATOR AND FORCES OF INERTIA ON THE DEFLECTION OF THE SHAFT MUST BE CONSIDERED. THE AUTHOR CONCLUDES THAT CALCULATING THE ELECTROMAGNETIC FIELD FOR TORSIONAL VIBRATIONS GIVES A SMALLER VALUE FOR NATURAL VIBRATION FREQUENCY AND FOR TRANSVERSE VIBRATIONS LEADS TO A LOWERING OF THE PRIMARY CRITICAL SPEED.

THE PRIMARY CONCLUSION DRAWN WAS THAT THE USE OF THIS METHOD MUST BE EVALUATED SEPARATELY FOR EACH PROJECT IN RELATION TO LOCAL CONDITIONS AND DESIGN CRITERIA. TO EFFECT ACTUAL ECONOMICS, DESIGNERS CAN STANDARDIZE THE RECURRING COMPONENTS OF SEPARATE PARTS OF POWERPLANTS, SUCH AS ENCLOSURES FOR SPIRAL CASES AND DRAFT TUBES; EMBEDDED STRUCTURAL SLOTS, KEYS, DRAINS, ETC.; INSPECTION AND DRAINAGE GALLERIES; AND REINFORCED PANELS FOR RUN-OF-THE-RIVER POWERPLANTS WITH NOT OVER 50 M OF HEAD. ONLY FOR RUN-OF-THE-RIVER PLANTS WITH HEADS LESS THAN 20 M CAN THE EXCLUSIVE USE OF THESE COMPONENTS IN A STRUCTURE BE JUSTIFIED TECHNICALLY AND ECONOMICALLY. MANUFACTURING COSTS CAN BE REDUCED TO 40-45 RUBLES CU M TO EFFECT IN-PLACE COSTS OF 50-60 R/CU M. IDEAL USE IS BUILDING A SERIES OF 20 SUCH PLANTS IN SEQUENCE OF 2-3 AT A TIME, SERVED BY THE SAME MOBILE PRODUCTION-LINE MANUFACTURING PLANT AND CONSTRUCTION EQUIPMENT.

THE TREATMENTS WERE TO LEACH THE SOIL WITH WATER ALONE AND TO USE WATER PLUS ELECTRICITY. EACH TEST CONSISTED OF A BOXLIKE BLOCK OF SOIL BOUNDED SO THAT ELECTRICITY WAS CONFINED TO MOVING IN A DIRECT PATH FROM ONE END OF THE BOX TO THE OTHER. THE CHEMICAL TRENDS SHOWN MAY BE CONSIDERED FAVORABLE TOWARD RECLAIMING ALKALI SOIL. ELECTRICAL TREATMENT APPEARS TO PROMOTE CALCIUM CARBONATE, WHICH IS GENERALLY UNAVAILABLE FOR EXCHANGEABLE SODIUM, ENCOURAGE REPLACEMENT WITH CALCIUM, AND INCREASE MOVEMENT OF SOLUBLE SALTS, PARTICULARLY SODIUM SALTS, TOWARD THE CATHODE. ELECTRICAL TREATMENT WAS FOUND TO INCREASE THE REACTION OF CARBONATES, THUS RELEASING CALCIUM FOR EXCHANGE. ALTHOUGH ELECTRICITY ENCOURAGED SOLUTION MOVEMENT AND PROMOTED DESIRABLE REACTIONS, LEACHING AND DRAINAGE WERE CONSIDERED MAJOR FACTORS IN CARRYING THE UNDESIRABLE MATERIALS AWAY. IN THE LABORATORY TESTS, ELECTRICAL TREATMENT APPEARED TO CAUSE A DESIRABLE ENVIRONMENT THAT MAKES LEACHING AND DRAINAGE MORE EFFECTIVE WHEN COMPARED TO SIMILAR TESTS WITHOUT ELECTRICITY.

SINCE NONE OF THE PLANTS NEARBY PRODUCED CEMENT OF THE REQUIRED QUALITY, ESPECIALLY FOR LOW-HEAT EVOLUTION, A PROGRAM WAS INITIATED TO DEVELOP A CEMENT THAT WOULD PRODUCE CONCRETE OF THE REQUIRED QUALITY. STARTING WITH THE CEMENTS NEAREST TO MEETING THE REQUIREMENTS, A SPECIAL INGURSK HYDROTECHNICAL CEMENT WAS DEVELOPED BY SUBSTITUTION OF DIATOMITE FOR A PART OF THE CLAY COMPONENT OF THE CLINKER, RECALCINATION OF THE CLINKER, VIBROMILLING AFTER REGULAR MILLING, AND ADDITION OF FLY ASH. TESTS SHOWED THAT THIS CEMENT WITH A COEFFICIENT OF SATURATION OF 0.84 COULD BE CLASSED AS A LOW-HEAT CEMENT AND THAT IT PRODUCED CONCRETE WITH A COMPRESSIVE STRENGTH OF 500 KG/SQ CM.

THE GOOD STORAGE PROPERTIES AND WETTABILITY OF THIS CEMENT WERE OBTAINED BY ADDING MONOETHANOLAMINE DURING MILLING. BECAUSE A BETTER STORING CEMENT WAS NEEDED FOR COLD HUMID CONDITIONS, A RESEARCH TEAM FROM SEVERAL INSTITUTES COOPERATED TO DETERMINE WHAT ADDITIVES YIELDED THE BEST PLUGGING CEMENT IN TERMS OF WETTABILITY, STRENGTH, VISCOSITY, AND OTHER PROPERTIES. AMINO ALCOHOLS, MONO-, DI-, AND TRIOTHANOLAMINE, WERE TESTED USING BOTH HIGH- AND LOW-ALUMINATE CEMENTS WITH AND WITHOUT SODIUM CHLORIDE. THE PAPER DISCUSSES THE PROPERTIES NEEDED IN THE NEW CEMENT, DEVELOPMENTAL TEST METHODS, AND RESULTS LEADING TO THE CHOICE OF MONOETHANOLAMINE AS THE MOST EFFECTIVE ADDITIVE FOR COLD OR HOT DRILL HOLES AT THE RECOMMENDED RATE OF 0.5 TO 1%, BY WEIGHT OF CEMENT. SLAG-PORTLAND CEMENT (40% SLAG) WITH ADMIXTURES OF 1% NACL AND 0.5% MONOETHANOLAMINE DURING MILLING KEPT A HIGHER STRENGTH AND FLOWABILITY IN SPITE OF THE NACL CONTENT (ADDED TO RAISE THE HYGROSCOPIC PROPERTIES). MONOETHANOLAMINE LOWERS WATER PERMEABILITY OF CEMENT MORTAR, DOES NOT CORRODE IRON, INTENSIFIES THE MILLING PROCESS TO PRODUCE FINER GRINDS, INCREASES WATER-CEMENT RATIO, AND LOWERS THE SPECIFIC WEIGHT OF THE GROUT (IMPORTANT WHEN GROUTING DEEP DRILL HOLES).

OTHER ADVANTAGES OF THIS METHOD ARE THAT IT USES NESTEROV'S PRINCIPLES FOR LARGE WETTED SURFACES, FAMILIAR TO SOVIET SOIL SPECIALISTS; THE TEST ARRANGEMENT IS SIMPLE TO SET UP AND MEASUREMENTS ARE MADE EASILY; AND IT IS CAPABLE OF AUTOMATION. DISADVANTAGES ARE THE LONGER TIME REQUIRED FOR OBSERVATIONS AND THE LARGE QUANTITY OF WATER USED. SEEPAGE MEASUREMENTS WERE CONDUCTED ON SEVERAL TEST PLOTS IN THE GOLODNAIA STEPPE OF CENTRAL ASIA OVER A 3-YEAR PERIOD. THE 2.6-M-DIA METAL INNER RING SET IN A 10-CM FURROW AND THE 7.8-M-DIA EARTH OUTER RING FACED WITH POLYETHYLENE FILM AUTOMATICALLY WERE KEPT FILLED WITH WATER TO A CONSTANT DEPTH OF 30 CM. SOIL MOISTURE WAS MEASURED BY NEUTRON METERS INSERTED INTO OBSERVATION DRILL HOLES. BEFORE-AND-AFTER MEASUREMENTS PERMITTED FIXING CHANGES IN THE POSITION OF THE WETTING FRONT, AND WITH TIME, COMPUTING THE WETTING AND SEEPAGE RATES HORIZONTALLY AND VERTICALLY. TESTS SHOWED THAT WETTING RATE WAS AT FIRST GREATER THAN SEEPAGE; BUT LATER THEY BECAME APPROXIMATELY EQUAL AND THE CURVES BECAME FLAT SLOPES, INDICATING A STABLE SEEPAGE RATE.

DESIGN CALCULATIONS FOR MODERN POWERFUL HYDRAULIC UNITS, SUCH AS AT KRASNOIARSK POWERPLANT IN THE USSR, SHOULD INCLUDE THESE FACTORS. THE ROTOR IS CONSIDERED AS A VIBRATING STRING WITH 2 OR 3 SEATED MASSES ALONG IT, DIVIDING IT INTO SEVERAL PARTS. A. N. KRYLOV'S METHOD OF INITIAL PARAMETERS CAN BE USED FOR CALCULATING SHAFTS ON AN ELASTIC FOUNDATION AND CRITICAL SPEEDS OF ROTORS. THE METHOD IS EQUIVALENT TO SUBSTITUTING A SYSTEM OF DIFFERENTIAL EQUATIONS WITH CONSTANT COEFFECIENTS FOR DIFFERENT ROTOR PARTS FOR A DIFFERENTIAL EQUATION WITH VARIABLE COEFFICIENTS. THE SOLUTION IS WRITTEN WITH THE HELP OF FUNCTIONS FORMED BY NORMAL FUNDAMENTAL SYSTEMS. THE INITIAL PARAMETERS USED VALUES FOR WEIGHTS, MOMENTS OF INERTIA OF THE MASS, AND FLEXIBILITY OF THE SUPPORT. EXAMPLES OF SOLUTIONS ARE GIVEN AND COMPARED WITH RESULTS OF CALCULATIONS FOR CRITICAL SPEEDS WITHOUT CONSIDERING THESE FACTORS. IF ELECTRONIC COMPUTERS ARE USED, THE FUNCTIONS CAN BE CALCULATED ACCORDING TO FACTORIZATION FORMULAS, CONTAINING 3 TO 4 FACTORS. JF - TRANSLATION OF: ENERGOMASHINOSTRVENIE NO 11, P 6-10, 1964.

THE DIFFERENTIAL EQUATIONS OF MOTION SHOW THAT THE VELOCITY OF MOVEMENT OF THE MONOMOLECULAR FILM IS PROPORTIONAL TO THE WIND VELOCITY. HOWEVER, THE DIRECTION OF MOTION OF THE FILM DOES NOT COINCIDE WITH THE WIND DIRECTION, DUE TO THE EFFECT OF THE CORIOLIS FORCE. ACCORDING TO THIS THEORETICAL DERIVATION, THE RATIO OF WIND SPEED TO FILM SPEED IS EQUAL TO 32; WHEREAS FIELD OBSERVATIONS SHOW THAT THIS RATIO IS APPROXIMATELY EQUAL TO 20. THIS DISCREPANCY IS ATTRIBUTED TO THE EFFECT OF VARIOUS SIMPLIFYING ASSUMPTIONS; E.G., THE SIMPLIFICATION OF THE EQUATIONS OF MOTION OF THE ATMOSPHERE, THE ASSUMPTION THAT THE WIND VELOCITY IS UNIFORM, AND THE DISREGARD FOR THE EFFECT OF TEMPERATURE DIFFERENCES BETWEEN VARIOUS POINTS IN THE ATMOSPHERE.

The procedures used for providing levee protection under the early conditions of no storage dams on the river generally involved large quantities of quarry-run stone placed on the levee by means of railroad cars. Conditions in 1961, with a high degree of flood protection provided by Hoover, Davis, and Parker Dams call for different methods. Channelization activities on the Lower Colorado River still provide levee protection to surrounding land areas; however, greater stress is given to bank stabilization along the normal stage channel banks in order to maintain the channel in its designed location and alinement and to control the movement of sediment from the alluvial banks. The methods being used by the Bureau of Reclamation are the result of 50 yr of experience. Innovations in the methods of placing riprap stone for bank stabilization purposes have resulted in the development of fast and economical procedures that have proven entirely satisfactory when used on the non-cohesive, alluvial banks typical of the Lower Colorado River.

The structure of the Central Interior region and the Atlantic and Gulf Coastal Plains is shown by contours drawn on different rock units. Deformed and metamorphosed Precambrian and Paleozoic rocks in the Eastern States and Paleozoic and Mesozoic rocks in the Western States are shown by various color patterns. Intrusive igneous rocks, such as batholiths, laccoliths, stocks, plugs, and dikes, and the extensive areas of volcanic rocks of different ages are shown. The tectonic map is of special interest in the search for petroleum, natural gas, and ore deposits, for it provides a geologic and tectonic framework for the delineation of major mineral provinces.

Brief reports on selected topics taken from geological investigations in these areas are given. Geologic mapping in the Central region covered parts of the Black Hills, North and South Dakota; the Gas Hills and Hiland areas, Wyoming; the Maybell-Lay area, Colorado; and the Tucumcari-Sabinoso area, New Mexico. Brief accounts of activities and findings in these areas are presented. The Turtle Lake quadrangle, Washington, is described, as is the geology of the Mauch Chunk area, Pennsylvania. Compilation of data on Paleozoic and Mesozoic rocks of the Colorado Plateau region continued, with emphasis on Triassic lithology, Entrada sandstone of the San Rafael group, and diatremes. Other geologic topical studies include investigations of Dripping Spring quartzite, Inyan Kara group, and Morrison formation; regional synthesis of eastern Montana and the Dakotas; radioactivity of Devonian and Mississippian black shales of the Midcontinent region; reconnaissance for U in Alaska; and U in organic substances in alpine meadows of California. Geophysical investigations comprised regional studies in the Colorado Plateau and Texas Gulf Coastal Plain, physical properties of ore and host rock, development and maintenance of radiation-detection equipment, gamma-ray logging studies, and correlation of airborne radioactivity data and areal geology. Distribution of elements studies, botanical and geochemical research, mineralogy and geochemistry of U deposits in Karnes County, Texas, and mineralogical and radioactivity investigations are described. Accounts of analytical services rendered and progress on techniques research are given. Projects under study in the trace elements research program include: physical behavior of Rn, absorption and scattering of gamma-rays, organic geochemistry of U, distribution of U in igneous complexes, synthesis and solution chemistry of U-bearing minerals, stable isotope analysis, nuclear geology, geochronology, isotope geology of Pb, natural radioactivity of the atmosphere, thermoluminescence of radioactive materials, geology and geochemistry of Th, geologic thermometry of radioactive materials, and crystallography of U and associated minerals.

The average percentage transmission of surface light intensity, at the Secchi disc depth, was 14.7 percent. Discrepancies in the relationship of disc readings to percentage transmission of surface light are related to the condition of the sky and sea. It is suggested that these discrepancies can best be explained on the basis of the spectral sensitivity of the human eye and its response to surface glare.

IT DEALS PRINCIPALLY WITH IRRIGATION WELLS, BUT MUCH OF THE CRITERIA ARE APPLICABLE TO DOMESTIC, INDUSTRIAL, AND MUNICIPAL WATER WELLS. THE CRITERIA GENERALLY DO NOT APPLY TO WELLS FOR GROUND WATER OBSERVATIONS, GROUND WATER RECHARGE, DRAINAGE, EXCAVATION DE-WATERING, DRILLING WATER SUPPLY OR FOR OTHER TEMPORARY OR SPECIAL PURPOSES. THE BUREAU DRILLS WELLS IN THE 17 WESTERN STATES AND IN SOME OF THE TERRITORIES. AVAILABLE DRILLING EQUIPMENT AND MATERIALS, WELL CONSTRUCTION METHODS, AND LOCAL PHYSICAL CONDITIONS VARY WIDELY OVER THIS LARGE AREA. THE AIM OF WELL DESIGN IS ALWAYS THE BEST POSSIBLE WELL FOR THE PURPOSE, TAKING INTO CONSIDERATION THE DEMAND, REQUIRED PERIOD OF SUSTAINED PUMPING, EFFECTIVE LIFE, INITIAL INVESTMENT, OPERATION AND MAINTENANCE COSTS, LOCAL REGULATIONS AND PRACTICES, AND NORMAL PRECAUTIONS ON SANITARY CONSTRUCTION AND AQUIFER CONTAMINATION. ACCORDINGLY, THE OBJECTIVE IS TO DESIGN THE MOST EFFICIENT AND ECONOMICAL WELL FOR ANY GIVEN AQUIFER AND PURPOSE.

Vermillion Cliffs areas, Utah; and Grants and Laguna areas, New Mexico. Brief reports on selected topics taken from geologic investigations in these areas are given. Geologic mapping in the Black Hills, South Dakota and Wyoming; the southern Powder River basin, Gas Hills, and Hiland-Clarkson Hill areas, Colorado; Thomas Range, Utah; and Tucumcari-Sabinoso area, New Mexico, is described. Activities involved in the geologic mapping of Turtle Lake quadrangle, Washington; Jarbridge quadrangle, Nevada; Mauch Chunk area, Pennsylvania; and phosphate deposits, especially their "leached zones," in Florida are outlined. Drilling on the Colorado Plateau from 1947 to 1956 is summarized, and ore reserves discovered as a result are analyzed. Coincidence of U occurrences with certain stratigraphic features in the major U-producing regions has permitted investigations of Triassic strata, Entrada sandstone of the San Rafael group, regional synthesis, localization and origin of U-V deposits, and diatremes on the Colorado Plateau. Petrographic analyses of some sandstone beds in the Inyan Kara group and associated rocks are outlined, as are those of the Dripping Spring quartzite. Recounted are findings from the regional synthesis of eastern Montana and the Dakotas and general research and resource studies. Progress in study of Permian strata of N. Texas and S. Oklahoma and Pennsylvanian sediments in the Midcontinent, and in reconnaissance for U in Alaska is reported. Regional geophysical studies of the Colorado Plateau and Texas Gulf Coastal Plain, gamma-ray logging studies, development and maintenance of radiation- detection equipment, correlations of airborne radioactivity data and areal geology, and other geophysical investigations are developed. A brief resume of geochemical, botanical, and mineralogical investigations is presented. Analytical services and research on techniques in the fields of radioactivity, spectroscopy, chemistry, and mineralogy are described. Physical behavior of Rn, absorption and scattering of gamma radiation, Rn and He studies, U in natural waters, organic geochemistry of U, distribution of U in igneous rocks, synthesis and solution chemistry of U-bearing minerals, stable isotopes, nuclear geology, geochronology, isotope studies of Pb, natural radioactivity of the atmosphere, thermoluminescence of radioactive minerals, geology and geochemistry of Th, and geologic thermometry of radioactive minerals are projects under study in the trace-elements program which are outlined in this report.

This study, dealing with new data, largely from extensive excavations and detailed topographic maps made by the U. S. Bureau of Reclamation in developing the great Columbia Basin Irrigation Project, returns to the earliest of the four interpretations: that channeled scabland is almost wholly the consequence of catastrophic flooding of glacial water across this part of the Columbia Plateau which remade preglacial valleys into an anastomosing complex of great river channels with huge cataracts, deep rock basins, and bars attaining magnitudes unknown elsewhere on earth. The new evidence is held to establish firmly the following points: JF - Bulletin of the Geological Society of America AU - BRETZ, J HARLEN AU - SMITH, HTU AU - Neff, George E AD - UNIVERSITY OF CHICAGO; CHICAGO 37, ILLINOIS; UNIVERSITY OF MASSACHUSETTS, AMHERST, MASS.; U.

Recent experimental test diets have produced specific deficiency syndromes for most of the vitamins and have indicated the possibility of developing specific deficiencies for amino acids, fatty acids, and other basic nutrients. During the past 3 years the first evidence of susceptibility to bacterial disease in lots of fish with sub-clinical manifestations of vitamin deficiencies has opened an entire new field in fish-disease study. In this review (a portion of a symposium on fish diseases) the nutrition of salmonids is emphasized. Advancements within the last 10 years in the fields of avitaminosis, hypervitaminosis, susceptibility to disease and general malnutrition are mentioned and a table is included which compares the specific avitaminosis syndromes observed in fish with those observed in other experimental animals.

Its character has been controlled and changed as the result of construction of Hoover and Davis Dams. The composition of the fish fauna has changed, also. There are now known from the area 3 native and 11 exotic species. Six additional fishes native to the Colorado River Basin and two other alien forms may occur. Competition with the exotic species and changes in ecological conditions of the river have apparently brought about decline in the numbers of native fishes. This peculiar fauna, so poorly known at present, should be the object of more scientific investigation and survey before it becomes extinct or its composition is further altered. Introduced species have increased since the building of Hoover Dam. The largemouth black bass is the most important game species in Lake Mead and the rainbow trout is the leading sport fish in Lake Mohave. It is probably unnecessary to have a closed fishing season because the exotic game fishes are so firmly established. Introduction of additional alien species is not recommended. Further stocking of the largemouth black bass or forage fishes in Lake Mead is discouraged, although continued planting of rainbow trout below. Hoover Dam is necessary to meet anglers' demands. Further investigation of the sport fishery in Lake Mead National Recreational Area is desirable. JF - Transactions of the American Fisheries Society AU - Wallis, Orthello L AD - U. S.

Fishes taken for sport and food are the eastern brook trout, rainbow trout, smallmouth black bass and rock bass. Rainbow trout are used to fill the gap between the waters capable of supporting eastern brook trout and those in which smallmouth bass are native. Native species are stocked in virgin waters, in research areas, and in streams where rainbow trout are not well established. A modern trout hatchery, operated by the U. S. Bureau of Fisheries, and thirty-five concrete rearing pools make up the physical plant. More rearing pools are planned. All stocking has been done in the fall, but later at least part of the fish may be planted in the spring prior to the opening of the fishing season. The prohibition of natural baits insures the preservation of native stream organisms and prevents the introduction of undesirable exotic species. A creel census on representative watersheds promises to give accurate information on the yield of the streams.
