Simulation Of Steady And Unsteady Flows In Channels And Rivers, Roland W. Jeppson

Reports

The unsteady, one-dimensional Saint-Venant equations are solved by an implicit finite difference scheme to handle general channel and river flows. The initial conditions for the unsteady flow are provided by solving the steady varied flow equation for the specified boundary conditions. The solution for the unsteady flow allows any of eight separate boundary conditions to be specified which are composed of combinations of specifying the depth or discharge as functions of time at either the upstream of downstream ends, with the stage-discharge relation or constant depth and flow rate specified at the other end. Typical solutions showing the spatial and …

Component Description Of Sediment-Water Microcosms, James Hill Iv

Reports

The development and application of complementary variables (potential and flux) for modeling environmental systems are illustrated for the hydraulic and dissolved oxygen subsystems of laboratory microcosms. These sediment-water, semi-continuous flow microcosms were used to determine nutrient interchange and mercury interactions under lighted (aerobic) and dark (anaerobic) conditions. The approach of using complementary variables to describe such systems forces a more complete conceptual understanding of the system and better attention to those parameters (many of which are unknown) requiring measurement. Complementary variables are incorporated into basic linear component equations which describe basic processes of energy transfer and transformation. The components are …

Hydrologic Model Studies Of The Mt. Olympus Cove Area Of Salt Lake County, J. Paul Riley, Vernon J. Rogers, George B. Shih

Reports

Urban development on any natural drainage basin causes marked changes in the runoff characteristics of the basin. Urbanization alters natural drainage channels and reduces average infiltration rates. Thus, flood conditions are enhanced both within the urbanizing area itself and at downstream locations, where existing channels might not be able to cope with the increased rates of water flow. The Olympus Cove area in Salt Lake County is undergoing rapid urban development, and potential flood hazards within the area and at downstream locations are thereby increasing. Recognizing this situation, officials of the Sale Lake County took the initiative in organizing an …

Review Paper: Evaluation Of Techniques For Algae Removal From Wastewater Stabilization Ponds, E. Joe Middlebrooks, Donald B. Porcella, Robert A. Gearheart, Gary R. Marshall, James H. Reynolds, William J. Grenney

Reports

Introduction: Approximately 90 percent of the wastewater lagoons in the United States are located in small communities of 5,000 people or less. These communities, many with an average daily wastewater flow of only 175,000 - 200,000 gallons, do not have the resources to keep man at the lagoon sites throughout the day (38). A high degree of technical knowhow is usually lacking in these communities. Often only periodic inspection or maintenance is carried out by the general municipal work force. Therefore, the development of a relatively inexpensive method that does not require sophisticated and constant operation or extensive maintenance is …

Evaluating Water Reuse Alternatives In Water Resources Planning, A. Bruce Bishop, William J. Grenney, Rengasan Narayanan, Stanley L. Klemetson

Reports

Water reuse is a recognized option for augmenting water supplies to provide for expanded water needs. A methodology is developed for examining optimal strategies for water reuse within the context of the total water resources system, including both the provision of water supplies for various uses and management of wastewaters. A model of the water resources system is formulated as a “transportation “ or “transshipment” problem in linear programming depicting the possible sources of supply, including effluent sources available for reuse, which can be used to satisfy the requirements of various water users. The optimizing objective in the model is …

Effect Of Temperature On Algal Removal By Alum Coagulation, Muhammad Anis H. Al-Layla, E. Joe Middlebrooks, Donald B. Porcella

Reports

Questions about the effect of temperature on algal cell coagulation and the relationships between algae removal and temperature, alum dosage, paddle speed, flocculation time, and settling time are answered. The investigations consisted of two series of tests: Studies on algae cultured under laboratory control, and algae in wastewater stabilization ponds. The jar-test technique was used for the coagulation of algal suspensions by alum. Coagulation of algae is caused mainly by the insoluble flocs of aluminum hydroxide. Other aluminum species also have coagulative properties but are far less effective. The destabilization of algal colloids results from enmeshment within the hydroxide precipitates, …

Pheasant Reproduction And Survival As Related To Agricultural Fertilizer Use, Lawrence Francis Fredrickson

Electronic Theses and Dissertations

Wing-clipped wild pheasants (Phasianus colchicus) were stocked in 1-acre and 0.5-acre pens having oat and bromegrass cover in 1972 and 1973 to test effects of fertilizer (Formulations: 34-0-0, 18-46-0, 0-46- 0, and 0-0-60) on pheasant reproduction and survival. One-half of the pens were fertilized with the recommended rate of pelleted fertilizer and the other half without fertilizer. Complete nest searches in July showed that nesting success was not significantly different (P>0.05) between treatments for both years. No significant difference (P>0.05) was found in clutch size or in number of ovulated follicles from control and experimental hens. Significantly more …

Electronic Theses and Dissertations

One thousand five hundred catchable brown trout (17-26 cm) were stocked into the South Fork of the Yellowbank River May 17, 1973. Samples were taken one month apart from May 22, 1973, through October 29, 1973. Fifteen-minute drift samples were collected every hour for 24 hours and trout were captured every 4 hours. Trout captured ruing the study varied in condition ® from 1.34 to 2.55. Condition progressively decreased through August, rose in September, and decreased again by the October sample. The average weight of brown trout increased through the September sample and decreased in October. Two peaks in number …

Rate Of Growth As A Method Of Assessing Water Quality, George L. Johnston

Masters Theses

A study of the Embarras River basin was conducted to determine if rate of growth could be used as an indicator of water quality. Six species of sucker were collected from five locations using hand seines and electrofishing gear from December 1970 to December 1971. Tests of eighteen water quality parameters were conducted from November 1970 to November 1971.

The fish were measured and scale samples taken. The rate of growth of the fish taken at the five stations was analyzed and compared using the single classification analysis of variance. Condition factors were also compared.

Fugitive Particulate From Highway Construction, Kennard F. Kosky

Retrospective Theses and Dissertations

National ambient air quality standards for particulate matter have been promulgated since April, 1971. While effects of stationary sources on these standards have been examined, little research has been accomplished on the effects of fugitive particulate. This thesis examines the environmental impact of a fugitive dust source, Highway Construction. Using the High-Volume reference method for particulate sampling, the effect of Highway construction was determined. An analysis of concentrations, distance influences, meteorological influences, particle sizes and construction influences is presented. The data obtained from this study indicates the major influence of concentrations is a function of distance and sampling height. Particle …

The Mormon Role In Irrigation Beginnings And Diffusions In The Western States: An Historical Geography, Kelly C. Harper

Theses and Dissertations

Irrigation has played an important part in the development of the Western States. Its beginnings have often been associated with the Mormon settlement in Utah. However, irrigation had its inception in the West long before the Mormons came to the Great Basin in 1847. The spatial extent of irrigation before this date included limited acreage in nearly every Western State.

Before their arrival in the Great Basin the Mormons had become acquainted with irrigation methods. Knowledge of irrigation had diffused to them primarily from the Spanish in the Southwest. Thus, they were well prepared to begin their irrigation enterprises in …
