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 …

An Economic Appraisal Of Reuse Concepts In Regional Water Supply Planning, Rangesan Narayanan, Bartell C. Jensen, A. Bruce Bishop, Kenneth S. Lyon

Reports

Using a conceptual model of a water supply firm, the necessary conditions for production and market efficiency are derived when renovated wastewater is considered as a potential water resource. The nature and extent of the supply augmentation due to recycled reuse is demonstrated using classical optimization techniques. Three stages of short-run supply corresponding to no recycling, partial recycled reuse and complete recycling of all reclaimable water are identified through appropriate Lagrangian Multipliers as well as graphical techniques. A mathematical programming model is structured to determine the optimal water resource allocation and pricing policy for Salt Lake County. By maximizing the …

The Effect Of Urea On The Sedimentation Coefficient Of The Curly Top Virus Dimer, Allen H. Smith

Undergraduate Honors Capstone Projects

The purpose of this project is to investigate the effect of increasing concentrations of urea on the sedimentation rate of the curly top virus dimer as measured by ultracentrifugation techniques. In general, urea causes the breaking of hydrogen bonds in macromolecules--in the case of the virus, increased concentrations of urea should cause changes in the configuration of the virus and may possibly cause a separation of the dimer into monomers. From previous centrifugation studies, we know that the dimer has a characteristic sedimentation coefficient(S) of about 80 Svedbergs; the monomer has an S value of about 55 Svedberg units. Increased …

English-Vietnamese Translation: An Internship, Blaine L. Hart

Undergraduate Honors Capstone Projects

The art of translation lies in a literary limbo, subservient to the creativity and expressions of others. Yet in attempting to bridge two different languages and cultures, it entails unique problems as difficult as those encountered in any other literary activity.

The following is the report of a project carried out with the Translation Department of the Church of Jesus Christ of Latter-Day Saints in the fall of 1975 as a senior Honors project in fulfillment of requirements for graduation from the Honors Program at U.S.U. Since this internship itself formed the bulk of my project, the following is presented …

Recent Reforms In Campaign Finance Regulations And Their Potential Effect On Federal Elections And Reflections On Washington As A Congressional Intern, Randy D. Funk

Undergraduate Honors Capstone Projects

In the spring of 1975, upon learning that I had been selected as a summer intern in Congressman Gunn McKay's office, I thought that such an experience might readily serve as the basis for my senior Honors project. I discussed this possibility with Dr. Douglas Alder, the Honors Program Director, and Dr. Wendell Anderson, the intern advisor. With their approval, I decided to write one paper on my impressions of Washington as an intern and then upon my return to school, research and write another paper on an issue related to Congress. This is the reason my thesis project is …

Colorado River Basin Modeling Studies: Proceedings Of A Seminar Held At Utah State University Logan , Utah July 16-18, 1975, Calvin G. Clyde, Donna H. Falkenborg, J. Paul Riley

Reports

Preface: Computer modeling is an important and valuable tool for water resources planning and management. In recent years many different modeling approaches and techniques have been developed. Some have been applied in the Colorado River Basin. A brief and incomplete search showed over fifty reports on modeling in the Colorado River Basin alone. The main motivation for this Seminar was the indication that (1) much duplication of effort is occuring among Colorado River modeling studies due to lack of information and (2) much of the knowledge now available on modeling is not being effectively applied to real problems. The overall …

An Empirical Comparison Of Confidence Interval For Relative Potency, Catherine H. Lung

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Biological assays are essentially biological experiments. To compare the potencies of treatments on an agreed scale is generally of more interest than to compare the magnitude of effects of different treatments.

The relative potency, R = a/b, is defined as the ratio of the means of two equally effective doses where a is the mean of A and bis the mean of B. It is an estimate of the potency of one preparation, A, relative to that of the other, B.

Different procedures have been proposed to obtain the values of R and its confidence interval. Three of the these …

Disposal Alternatives For Intermittent Sand Filter Scrapings Utilization And Sand Recovery, Jerry T. Elliott, Daniel S. Filip, James H. Reynolds

Reports

A three phase study is used to develop disposal alternatives and cost analysis for algae laden sand scrapings removed from intermittent sand filters used to polish wastewater lagoon effluent. Phase I, Irrigation Technique, explores the feasibility of supplying sufficient water to sand scrapings to leach out entrapped material. Details of removal with amount of water applied are presented. Phase II, Soil Application, tests with lysimeters soil response to application of the algae laden sand material. Physical and chemical parameters are not markedly altered where algae laden sand is applied to the soil surface. Phase III, Plant Bioassays, grew tall fescue …

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

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 …

Effect Of Salinity On Glycogen Content In The Brine Shrimp, Artemia Salinas, Of Great Salt Lake, Christon H. Merkley

Undergraduate Honors Capstone Projects

The brine shrimp, Artemia salinas, is one of the few organisms to be found in the hostile environment of the Great Salt Lake. Salt concentrations in the lake are found to exceed those in the oceans. In such an environment, the utilization of energy, even after it has been procured, presents a problem. The life inhabiting the lake has developed extraordinary adaptations to this and similar problems.

Electron micrographs produced by Dr. Nabil Youssef of Utah State University have revealed that unusual quantities of glycogen can be found in the muscle of brine shrimp taken from the Great Salt Lake. …

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

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 …
