Site Selection For Air Pollution Monitoring In The Vicinity Of Point Sources, John C. Brown

Retrospective Theses and Dissertations

Ever since air pollution became a national concern in the 1950's, more and more emphasis has been placed on collection of representative air samples for many purposed, to include (1) evaluation of the degree to which national ambient air quality standards are being met and (2) to monitor maximum emission levels from point sources. Until recently efforts were directed toward qualitative methods of siting monitors for representative sampling. Since the dispersion of effluents is most complex, the quality of the data collected on the basis of judgment and, more or less, incremental siting about the source, has become suspect. Furthermore, …

Cost Minimization For Coal Conversion Pollution Control: A Mixed Integer Programming Model, Michael F. Torpy, A. Bruce Bishop, Rangesan Narayanan

Reports

A mixed integer program was structured to identify the least cost combination of recycling and treatment alternatives that can be used to control the liquid, solid, and gas waste streams produced from a 750-megawatt coat fired steam electric power plant. The model compared methods of liquid stream recycle and waste discharge treatment to meet given air and water quality standards. The model was then used to study the effects on the optimal solution of changes in capital, operation and maintenance, and energy and water costs. In addition, the effects on optimum system design of changes in particulate and sulfur oxide …

Feasibility Of Accelerating Construction Of The Central Utah Project, Trevor C. Hughes, L. Douglas James, Frank Haws, C. Earl Israelsen

Reports

Introduction: Objective: In April, 1977 the President's statement on water projects recommended that a number of federal water development projects, including the Conneville unit of the Central Utah Project, not be completed. The ensuing efforts of project supporters brought about a review of the projected costs, benefits, and other political, social and environmental factors and consequently, the current issue is not whether or not the project should be constructed. Rather, the objective of this report is to examine the following question: Given the fact that at least the 5 units of the CUP which have already been authorized will eventually …

Utah's 1977 Drought, Trevor C. Hughes, Clark Bigler, Jerry Olds, Richard Griffin, Arlo Richardson, L. Douglas James, Norris Stenquist, James Harvey

Reports

The Utah Drought of 1976-1977 has been characterized as the wettest drought in history. It was produced by the driest winter season of record followed by summer rains which were much wetter than normal in many regions of the state. Stream-flow is highly correlated with winter rather than summer precipitation and therefore the most severe impacts of the drought were related to the record low stream-flow during 1977 plus the ski industry impacts which were directly related to 1976-1977 snowfall. Drought impacts upon several sectors of the economy plus the extensive responses of all levels of government in the form …

This study generated a limited amount of new data and gathered existing data and information related to surface and underground water within a 50-mile radius of Emery, Utah, but restricted primarily to the …

Engineering Properties And Slope Stability Settlement Analysis Related To Phosphate Mine Spoil Dumps In Southeastern Idaho, Richard E. Riker, Loren R. Anderson, Roland W. Jeppson

Reports

The engineering properties of waste spoil from phosphate mines in Southeastern Idaho were determined through field and laboratory testing. Based on these properties, the slope stability and settlement characteristics of phosphate spoil dumps were determined. Hypothetical examples illustrate possible modes of foundation failures. Such failures might occur when weak foundation soils exist of when there is a lack of embankment-foundation preparation prior to the disposal of waste material. Adequate protection against slope failure occurring through the embankment material can be accomplished by grading embankment finish slopes to 2 ½ horizontal to 1 vertical or flatter and taking proper caution to …

Reports

Based on the equations of continuity and motion for sediment transport and the dynamic equation of spatially varied open channel flow, a computer simulation of erosion is developed. The water source for the erosion simulation may be rainfall or snowmelt. To provide snowmelt a computer simulation giving the rate of snowmelt from limited climatic data has been adapted to work conjunctively with the erosion model to provide a dynamic solution to erosion and overland flow, from precipitation and other limited climatic data. The computer simulation model has been tested using climatic data at and near the phosphate mine in Southeastern …

The Impact Of Energy Resource Development Of Water Resource Allocations, John E. Keith, K. S. Turna, Sumol Padunchai, Rangesan Narayanan

Reports

This research used a linear programming model of the agricultural and energy sectors of Utah to examine the economically efficient allocation of water between agriculture and energy. Data were collected for agricultural returns, costs, and water requirements; energy returns, costs, and water requirements; and water supply costs. Results indicate that if large scale energy development occurs in the Colorado River Basin in Utah, most of irrigated agriculture will be eliminated, given Utah’s consumptive use constraint under the Upper Colorado Rive Compact. On the other hand, for two more “probable” levels of energy development, including the Energy Research and Development Administration’s …

Hydraulic Characteristics Of Pvc Pipe In Sanitary Sewers (A Report Of Field Measurements), Ronald R. Bishop

Reports

Introduction: Since pipe made of poly vinyl chloride (PVC) is relatively new, its hydraulic characteristics that cause fluid friction head loss are not as well known as those of cast iron and concrete pipe. The lack of universally accepted roughness parameters for PVC pipe is attested by the fact that most textbooks dealing with the hydraulics and the fluid mechanics do not include such values. The hydraulic characteristics of PVC pipe have been measured in the laboratory studies for both open channel flow conditions, Neale and price (1), and for full flow conditions, Jeppson (2). However, no studies are known …

Conceptual system models were developed for the hydrologic system and for the sociological system. The sociological variables were identified as they related to the steps in the process of the model. Following the conceptual decision process model the social elements of the model were calibrated from data obtained from field studies and mathematical equations were developed and tested. Finally simulations of the process were run. After adjustments were made the model was found to function. Several methodological …

Salinity Management Options For The Colorado River. Damage Estimates And Control Program Impacts, F. Bruce Brown, Joel R. Cannon, Ralph C. D'Arge, Larry Eubanks, W. T. Franklin, Charles W. Howe, Ernest B. Jackson, K. L. Leathers, Frank E. Robinson, Don Snyder, Jeffrey T. Young, Robert A. Young

Reports

Rivers draining arid basins increase in salinity content in the downstream area to the point where water users are often significantly damaged. The problem in some cases can be ameliorated by altering upstream water and land use practices. An economic trade off exists between the cost of such upstream efforts and the downstream benefits achieved. This report examines options for salinity management in the Colorado River Basin. The study sought to provide additional information to estimate 1) economic damages caused by various salt concentrations to agricultural and municipal water users and 2) economic costs of salinity control measures by upstream …

Investigations Of Inertia Effects On An Infinite Solid Cylinder Due To Thermal Shock, Roland Vanderbilt Williams

Retrospective Theses and Dissertations

In this paper the effects of inertia are explored for the case of a thermal excitation applied on the surface of an infinitely long, solid circular cylinder. The linear uncoupled field equations for a homogeneous, isotropic, thermoelastic medium are used to derive the desired field equations of stress and displacement. The solution procedure included, first, the determination of the thermal boundary value problem from the energy equation which is identically satisfied for the uncoupled condition. Secondly, substitution of the strain-displacement relationships and the previously obtained thermal relation into the equilibrium equation containing inertial effects. The equilibrium equation is the only …

Predicted And Measured Drainable Porosities For Field Soils, R. W. Skaggs, Larry G. Wells, S. R. Ghate

Biosystems and Agricultural Engineering Faculty Publications

Experiments were conducted on large field cores to determine the relationship between drainage volume and water table depth for five soils. The measured drainage volumes were less than predicted from the soil water characteristics for three soils, but were in good agreement for the other two. Drainable porosities were calculated from both theoretical and experimental drainage volume-water table depth relationships by assuming that the unsaturated zone is essentially 'drained to equilibrium, with the water table. The experimental drainable porosities thus obtained were less than predicted.

Drainable porosities for drainage in two-dimensions were calculated from experimental results for one-dimension by assuming …

The Effect Of Potassium Permanganate On The Removal Of Iron And Manganese From Ground Water, Mohammad Reza Farvardin

Electronic Theses and Dissertations

For the past three years or so, a gradual migration of iron and manganese deposits has been observed in the water mains to the west of the East Water Treatment Plant of Brookings, South Dakota. These deposits have been gradually migrating further westward from the plant (8). Routine analyses of the treated water from the East Plant indicate that the iron and manganese levels are within the USPHS recommended limits (9). Consequently, conclusive evidence that this plant is the source of the problem does not exist. However, the analyses are normally conducted on samples collected shortly before backwashing the filters. …

The work of the engineering manager, like that of any manager, is getting things done through other people. In advancing to the first formal management position, the engineer usually passes through three career stages: engineer, informal manager, and formal manager. While advancing through these career stages, the engineer must increase …

Development Of A Quadratic Finite Element Solution Of The Convective-Transport Equation., David A. Dillard

Masters Theses

"A quadratic finite element has been developed for the solution of the general three-dimensional convective-transport equation. Inherent instabilities in the numerical solution arise when the convective terms in the governing equation become significant. An application of upwinding techniques to the 20 degree of freedom serendipity element failed to produce acceptable results. Upwinding was applied to the 27 degree of freedom Lagrangian element with good results. Results of the latter element are given for several problems, including a model of a round to round metal forming process"--Abstract p. iii
