An Energy Accounting Evaluation Of Several Alternatives For Hydropower And Geothermal Development, J. Clair Batty, J. Paul Riley, William J. Grenney, David A. Bell

Reports

Alternative management strategies for hydropower and geothermal development are myriad. This study does not attempt to evaluate or even summarize the many schemes which are possible. In an era of plentiful natural resources, economic analysis procedures for selecting a particular alternative have been developed which traditionally have tended to optimize on the basis of capital and labor. The approach taken in this study is based on the notion of optimum deployment of finite resources. A legitimate question which this study has attempted to address is: Does the construction of large water management facilities, such as hydropower dams, which involve huge …

A Rationale For Furrow Irrigation System Design And Management, Safa Noori Hamad May 1976

A Rationale For Furrow Irrigation System Design And Management, Safa Noori Hamad

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Mathematical and computerized models are developed to design and optimize furrow irrigation systems. The optimization process starts with land grading design, if any is needed, followed by a prediction of maximum non-erosive furrow stream size allowed on a given soil and the associated furrow-advance function. An average depth of application per irrigation is then assumed from which the wetting pattern along the furrow and the amounts of runoff water are predicted. A design of an Irrigation Runoff Recovery System, IRRS, is then executed, if desired, and system cost is determined. Using the predicted wetting pattern and the appropriate Crop Production …


Assessment Of Possible Carcinogenic Hazards Created In Surrounding Ecosystems By Oil Shale Developments, Gerald L. Dassler May 1976

Assessment Of Possible Carcinogenic Hazards Created In Surrounding Ecosystems By Oil Shale Developments, Gerald L. Dassler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the purposes of an environmental assessment is to foresee potential problems created by the introduction of contaminants into an ecosystem and to suggest appropriate control devices to mitigate the effects of such inputs. In the case of the oil shale industry, very little is known about the potential hazards, especially those related to the emission of organic compounds with carcinogenic potency. The hazards will probably be due to chronic exposures to the emitted compounds and the effects of such exposures are likely to take years to manifest themselves, as is the case with many carcinogenic substances. A precise …

Evaluation Of The Addition Of Granular Media Filtration To Wastewater Treatment Plants To Meet New Standards, Madhusudan M. Dawda, M. L. Davidson, E. J. Middlebrooks

Reports

A dual media filtration study was carried out at the central Weber Wastewater Treatment Plant in Ogden, Utah, to evaluate its feasibility as a tertiary treatment to meet new effluent quality standards. A review of the literature indicated that dual media filters were more efficient than conventional single media sand filters because of the “in depth” filtration achieved by dual media filters. An experimental filter was operated at four different hydraulic loading rates, ranging from 3 to 6 gpm/ft 2 (122.10 to 244.20 1/min/m2), to evaluate its effects on effluent quality. Hydraulic loading rate was shown not to affect suspended …

Iron Dynamics In A Gas-Water-Sediment Microcosm, Peter A. Cowan, V. Dean Adams, Donald B. Porcella Jan 1976

Iron Dynamics In A Gas-Water-Sediment Microcosm, Peter A. Cowan, V. Dean Adams, Donald B. Porcella

Reports

Iron dynamics in eutrophic systems were studied in the laboratory utilizing gas-water-Sediment phase sealed microcosms. Sediments from Hyrum Reservoir (2.4 percent iron by weight) were placed in the dark to simulate the hypolimnetic regions of a eutrophic impoundment. Iron both chemically and physically was readily available to microorganisms of the aqueous phase because iron in these systems was soluble. In the light microcosms, which simulated shallow littoral regions of eutrophic impoundments, iron was found in higher aqueous phase concentrations than was predicted chemically and physically; this was rationalized through biological mechanisms. The experiment was conducted in two phases: Phase I …

Application Of A Hydrologic Model To The Planning And Design Of Storm Drainage Systems For Urban Areas, George B. Shih, Eugene K. Israelsen, Robert N. Parnell, Jr., J. Paul Riley

Reports

A generally applicable hybrid computer program is developed to simulate runoff from urban watersheds, and is applied to represent the outflow hydrographs of three urban watersheds located within Salt Lake County, Utah. The gaged outflow of the watersheds provided a means for comparing the observed and the simulated final outflow hydrographs. Each of the three watersheds was subdivided into spatial units or subzones, and the outflow hydrographs for each subzone were obtained by abstracting interceptions, infiltration, and depression storage from the rainfall hyetograph of each subzone. The resulting hydrograph outflow of each subzone was routed to the Jordan River, the …


The Effects Of Artificial Destratification On The Water Quality And Microbial Populations Of Hyrum Reservoir, Douglas D. Drury, Donald B. Porcella, Robert A. Gearheart Jun 1975

The Effects Of Artificial Destratification On The Water Quality And Microbial Populations Of Hyrum Reservoir, Douglas D. Drury, Donald B. Porcella, Robert A. Gearheart

Reports

Artificial destratification is being increasingly used in attempts to improve water quality and control eutrophication. Most of the artificial destratification efforts are being conducted by public water supply utilities in efforts to improve reservoir water quality for culinary purposes. At present, artificial destratification is being conducted without a complete understanding of the process or its effects on the reservoir. Whether or not artificial destratification can control algal growth and other microbial processes is a controversial question. The effect of artificial destratification on the microbial flora must be understood if it is to be used effectively as a management tool in …

Water As A Factor In Energy Resources Development, A. Bruce Bishop, Melvin D. Chambers, William O. Mace, David W. Mills

Reports

Water, in many cases, is a key factor in the development of energy resources in the western states. The total water supply available in the arid west is fixed; yet potential water uses in the region are growing continually. In fact, in many areas quantities of water desired to be put to beneficial use has already surpassed the limit of local supplies as indicated by filings for water rights. The availability of water, in adequate quantities and of suitable quality, is one of the essentials to the economic viability of some economic sectors in the states in the Colorado River …


Water Quality As An Approach To Managing Recreational Use And Development On A Mountain Watershed: South Fork Of The Ogden River-Ogden Valley Area, Bruce A. Johnson, E. Joe Middlebrooks Jun 1975

Water Quality As An Approach To Managing Recreational Use And Development On A Mountain Watershed: South Fork Of The Ogden River-Ogden Valley Area, Bruce A. Johnson, E. Joe Middlebrooks

Reports

The South Fork of the Ogden River, one of several heavily used mountain watersheds along Utah's Wasatch Front, was studied between February 1 and November 1, 1974, to determine the effects of recreation on water quality.

Although the greatest impacts on water quality occurred during spring runoff, it was found that recreational use had a definite effect on water quality. Bacteriological parameters were found to be the most sensitive indicators of contamination.

Differences between heavy weekend and light weekday recreational use were reflected by differences in bacteriological counts. Also, it appears that changes in bacterial water quality were more closely …
