Assessment Of Control Alternatives For The Great Salt Lake, L. Douglas James, David S. Bowles

Reports

Introduction: Over the last few years, the rising level of the Great Salt Lake has changed Utah. It has inundated vast waterfowl feeding areas, crippled the salt industry, required raising transcontinental freeways and railroads, threatened metropolitan waste treatment plants, caused a major electrical outage, and damaged many properties. If nothing is done, approximately $3.6 billion of damages in 1985 dollars can be expected by 2050 (James et al, 1985, p.4). This threat led the State Legislature to set aside $100 million (an amount approximating the damages that had then occurred) in January 1985 to identify, select, and implement remedial measures. …

Evaluation Of Miramat Under High Velocity Flows, C. Earl Israelsen, Frank W. Haws

Reports

Introduction: Newly constructed earth channels and steep cut and fill slopes on construction projects need temporary protection from water erosion until a protective cover of vegetation can be grown. In some instances the temporary protective measures can be left in position to serve as part of the permanent system. Various kinds of vegetative and chemical mulches are available for use as temporary control measures, and other materials such as jute, fiberglass roving, and excelsior blanket are also in use. However, for large volumes of flow and for high velocities, more substantial materials are required. One class of such materials is …

A Statistical Comparison Of A Direct Filtration And A Conventional Water Treatment Facility In The Intermountain Region, Susan K. Burns, V. Dean Adams

Reports

Interest in low-cost direct filtration facilities and their effectiveness in treating the potable water sources of the Intermountain Region is increasing as the need for treated water supplies increase. Direct filtration is a water treatment scheme which does not include sedimentation and in some cases flocculation. Compared to conventional treatment, direct filtration has lowered capital costs, reduced space requirement, and decreased sludge quantities. Moreover, the direct filtration process may offer large reductions in coagulant dosages and costs.

Currently information comparing a direct filtration system to a conventional water treatment system in the Intermountain area is not readily available. The specific …

Sediment-Phosphorus Relationships In Deer Creek Reservoir, Jay J. Messer, Thomas B. Hardy, Jean M. Ihnat

Reports

Summary and Conclusions: Laboratory analyses of sediment samples recovered from Deer Creek Reservoir showed the sediments to have amoderate potential for serving as a source of phosphorus (P) for the overlying water solumn under anaerobic conditions. This source could account for the occurrence or exacerbation of blue-green algal blooms in the upper end of the reservoir when the sediment surface becomes anaerobic late in the summer. It could also delay the response of the reservoir to programs that decrease external P loading, if the upper end of the reservoir still has large enough algal blooms to render the sediment-water interface …

New Concepts For Preliminary Hydropower Design: The Powermax Slope, Binary Turbine Sizing, And Static Regain, Frank W. Haws, Eugene K. Israelsen

Reports

In Utah during the 1960s, the cost of producing electrical energy was as much, or in some cases more, by hydroelectric generation than by plants using steam from coal fired boilers. The relatively high hydropower cost was generally attributed to maintenance and replacement costs associated with plants that had been build in the 1920s. Utah Power & Light Company during the 1960 period decided not to renew power licenses and to abandon many small hdyroplants. Since 1973, rising coal and related fossil fuel costs have caused steam generation costs to accelerate and have made hydroelectric generation relatively more attractive. However, …

Management Of Groundwater Recharge Areas In The Mouth Of Weber Canyon, Calvin G. Clyde, Christopher J. Duffy, Edward P. Fisk, Daniel H. Hoggan, David E. Hansen

Reports

Proper management of surface and groundwater resources is important for their prolonged and a beneficial use. Within the Weber Delta area there has existed a continual decline in the piezometric surface of the deep confined aquifer over the last 40 years. This decline ranges from approximately 20 feet along the eastern shore of the Great Salt Lake to 50 feet along in the vicinity of Hill Air Force Base. Declines in the piezometric surface are undesirable because of the increased well installation costs, increased pumping costs, decreased aquifer storage, increased risk of salt water intrusion, and the possibility of land …

Direct Filtration Versus Conventional Water Treatment In The Intermountain Region, Susan K. Burns, V. Dean Adams, Steel B. Maloney

Reports

The direct filtration water treatment scheme does not include sedimentation and in some cases flocculation. Compared to conventional treatment, direct filtration has lowered capital costs, reduced space requirements, decreased sludge quantities, and reduced coagulant dosages. One objective of this research was the statistical comparison of the direct filtration, Utah Valley Water Purification Plant (Orem, Utah) and the conventional Little Cottonwood Water Treatment Plant (Salt Lake City, Utah).

An Economic Evaluation Of Benefits And Costs Of Maintaining Instream Flows, Rangesan Narayanan, Dean T. Larson, A. Bruce Bishop, Parvaneh Amirfathi

Reports

Instream flows enhance recreation, hydropower, fish and wildlife maintenance, and riverine ecosytems. Each use has water requirements that vary over time in unique patterns. The determination of the overall instream requirement at any given time must be considered in competition with the demand for municipal and agricultural uses. Two obstacles to integrating instream uses into the appropriation system of water law are difficulty in satisfying the legal requirements of an appropriation for a public use and the fact that instream flow uses are considered more "environmental" than "economic" in character. The extreme options for allocating flow between these user groups …

An Experimental Investigation Of The Effects Of Crude Oil On Two Freshwater Lake Ecosystems, Martin D. Werner, V. Dean Adams, Vincent A. Lamarra

Reports

Responses of two freshwater lake ecosystems of the Intermountain West to crude oil impaction were investigated. The research was conducted in two phases; in the first phase effects of crude oil were studied on an ecosystem established in three phase laboratory microcosms (gaseous-aqueous-sediment), which simulated the natural lakes. Notable responses of the microcosm ecosystem to oil impaction included: an increased oxygen demand by the biological community, nutrient immobilization, a reduction in plant biomass accumulation and a heterotrophically dominated ecosystem. The increased availability of biologically degradable reduced carbon (i.e., the oil) and nutrient immobilization, rather than toxic effects of oil on …

Effects Of Cadmium On Streams And Irrigated Agriculture In The Presence And Absence Of Oil Shale Leachate, Douglas A. Selby, Jean M. Ihnat, Fredrick J. Post, Jay J. Messer

Reports

Artificial streams, soil perfusion columns, and potted plants were exposed to 20 ug Cd/l in the presence and absence of unretorted oil shale leachate. High cadmium accumulations occurred in the stream biota, but did not measurably affect community structure or function. The presence of oil shale leachate had no effect on bioaccumulation or ecosystem structure or function. Nitrification in soil columns was enhanced by the presence of the organic fraction of oil shale leachate, but this effect was not observed when cadmium was present. Crop accumulation of cadmium was somewhat higher in alfalfa and radishes irrigated with leachate, but did …

The Evaluation Of Metals And Other Substances Released Into Coal Mine Accrual Waters On The Wasatch Plateau Coal Field, Utah, Alberta J. Seierstad, V. Dean Adams, Vincent A. Lamarra, Nancy J. Hoefs, Robert E. Hinchee

Reports

Six sites on the Wasatch Plateau were chosen representing subsurface coal mines which were discharging or collecting accrual water on this coal field. Water samples were collected monthly at these sites for a period of 1 year (May 1981 to April 1982). Samples were taken before and after each mine's treatment system. Water sampels were analyzed for major anions and cations, trace metals, physical properaties, nutrients, total organic carbon, oil and grease, trihalomethanes, and algal assay. Predictions were made as to the possible effects these coal mine accrual waters would have when used for drinking water, irrigation water, stock and …

Conjunctive Water Use Planning With Water Quality Constraints In Tooele Valley, Utah, Bhasker Rao K., Calvin G. Clyde, Rangesan Narayanan

Reports

The need for more efficient water management is gaining recognition due to the increased cost of water supply, the growth in the demand for water, and greater environmental and social impacts of water programs. "Conjunctive use" of surfact and groundwater resources provides opportunities for increasing net benefits to the water users. Past "conjunctive use" studies, however, have usually not included water quality constraints. In Tooele valley, Utah, spatial variation of groundwater qualtity (total dissolved solids) is significant. The areas of good (400-500 mg/1), fair (500-1,000 mg/1), and poor (1,000-3,000 mg/1) quality groundwaters were identified in an earlier study by the …

Reconnaissance Of Sediment-Phosphorus Relationships In Some Utah Reservoirs, Jay J. Messer, Jean M. Ihnat

Reports

Introduction: Phosphorus inputs to lakes and reservoirs from tributary streams and non-point sources are well-known contributors to nuisance algal growths that degrade water quality for potable and recreational uses in lakes and reservoirs. However, phosphours inputs to the euphotic zone may also occur from within the lake itself, as a result of releases from both oxic and anoxid sediments. Such releases may originate from phosphorus inputs to a lake or reservoir during high runoff periods in the previous winder or spring, or they may represent phosphorus trapped in the sediment many years earlier, when phosphorus contributions from natural or anthropogenic …

Hydraulics Of Solving Unsteady Debris Flow, Roland W. Jeppson, Salvador A. Rodriguez

Reports

This report describes methods for determining the depths, velocities, and flow rates of debris flows. As used herein debris flow consists of water rand solid particles sot that the density of the mixture is roughly twice as large as water, and due to the accumulation of large solid particles the viscosity of the mixture is large enough for the flow to exhibit typical laminar flow properties in which adjacent layers slide with respect to each other rather than intermix as occurs in turbulent flows of water for example. A previous report from this project proposed a basic equation for estimating …

Evaluation Of The Potential For Groundwater Transport Of Mutagenic Compounds Released By Spent Oil Shale, Robert E. Hinchee, V. Dean Adams, Jeffrey G. Curtis, Alberta J. Seierstad
