A Study To Determine The Cultural Awareness Of Engineering Students, Gordon P. Foreman

Undergraduate Honors Capstone Projects

Origins of the Study

As an engineering student in the Honors Program, I am continually faced with the stereotype of engineering students as people with no interest in social or cultural affairs and no consideration of things which cannot be tied down and measured. I decided to test this conception as best I could, even to comparing engineering students quantitatively to natural resources, history, and business majors. I attempted to get number comparisons for the index of relative awarenesses of culture. I suppose that only an engineering student would have the temerity to try to attach numerical values to something …

Multiple Uses Of Utah Irrigation Canals: Cache County As A Case Study, James J. Kennedy, Komain Unhanand

Reports

Irrigation use is an obvious benefit of Utah canals that has been recognized for over 100 years. This study attempts to illustrate other, less obvious, uses. the major use examined was recreational, but canals are presently functioning as storm drainage systems and have potential for diverting flood crests in many river systems.

Recreational use of canals falls into two categories. There is passive use such as its landscape values, affects on creating shade and bird-wildlife habitat, etc., that is difficult to quantify but no less important than active canal use such as tubing, hiking, bank-play, bicycling, etc. We selected several …

Development And Preliminary Application Of Mathematical Models To The Weber Basin, W. J. Grenney, D. S. Bowles, M. D. Chambers, J. P. Riley

Reports

The adoption of stream standards, whether for direct application or for the establishment of realistic effluent standards, creates a need to predict the impact of pollution loads on river water quality during critical flow periods or as the result of future user demands. Because of the complexity of aquatic systems, mathematical models are an excellent medium for bringing together the state-of-the-art knowledge from a variety of disciplines into a form which can be readily applied to practical problems. Applying a mathematical model to a river system has the added advantage of providing a structure for the systematic consideration of the …

Water Salvage Potentials In Utah, Volume I. Open Water Evaporation And Monolayer Suppression Potential, Trevor C. Hughes, E. Arlo Richardson, James A. Franckiewicz

Reports

An estimate of the potential in Utah for evaporation suppression by the monolayer film method is presented. The model estimates evaporation suppression as a function of wind speed, a four parameter exposure factor, and reservoir size. The estimated suppression factors vary from 0 to 30 percent and average 11 percent of the statewide total annual evaporation. Estimates of May to October evaporation and suppression potential are calculated for each of the 227 impoundments in the surface water inventory. A forthcoming report in this series will examine the potential for evaporation suppression by thermal destratification. This procedure, which is already being …

Asynchronous Logic Design With Flip-Flop Constraints, David Franklin Cox

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Some techniques are presented to permit the implementation of asynchronous sequential circuits using standard flip-flops. An algorithm is presented for the RS flip-flop, and it is shown that any flow table may be realized using the algorithm (the flow table is assumed to be realizable using standard logic gates). The approach is shown to be directly applicable to synchronous circuits, and transition flip-flops (JK, D, and T) are analyzed using the ideas developed. Constraints are derived for the flow tables to meet to be realizable using transition flip-flops in asynchronous situations, and upper and lower bounds on the number of …

Interactive Hybrid Computer Program As An Aid For Teaching Hydrology, Arif Hikmet Atali

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

The science of water resource planning and management implies the utilization of available water supplies in order to meet specific goals and objectives (Hill and Riley, 1972). Essential to effective planning and management is the consideration and analysis of all possible alternatives. Past research at Utah State University has demonstrated that the hybrid computer simulation of hydrologic processes is a reliable planning technique which provides the capability to examine many possible alternatives in a short period of time (Hill et al., 1970; Riley, 1970; and Riley et al., 1967). This technique, because of its interactive characteristics, is valuable also in …

Finite Difference Solution For Drainage Of Heterogeneous Sloping Lands, Fahd Salih Natur

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The two-dimensional problem of tile drainage on sloping heterogeneous lands was considered. The land surface and the impermeable boundaries of the problem were of a general shape. The flow in both the saturated and unsaturated zones was considered and the system was treated as one composite system. The problem was solved by a finite difference numerical method using the successive over-relaxation iterative (SOR) method for the steady state case with no local recharge, and a combined Newton inner iteration and successive over- relaxation outer iteration for the transient state case with local recharge. Both the rising water table and the …

Phosphorus Budget Of The Hyrum Reservoir - Little Bear River System, William A. Luce

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Phosphorus concentrations in the water of the Hyrum Reservoir - Little Dear River Watershed were determined by collecting 12 samples every two weeks over a seven month period and analyzing them for dissolved orthophosphate, total dissolved phosphorus, and total unfiltered phosphorus.

The concentrations obtained were used in conjunction with a water budget to determine a phosphorus budget. Apparent major inputs of phosphorus to the reservoir included a trout farm and runoff from agricultural land in the watershed.

Statistical analyses of the data were made to determine what effect precipitation, streamflow, and mileage downstream had on the concentrations of phosphorus in …

An Evaluation Of In-Stream Structures Designed To Provide Fish Habitat, Charles H. Call Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In-stream concrete structures were studied through model tests and river tests. The model studies indicated that four designs provided good habitat in the model stream. These structures were the inverted weir, the "V" structure, the slab with legs and the cylinder. Through the river studies it was determined that these structures did not influence enough of the total river area to be effective in providing good fish habitat. Also an appreciable amount of yearly maintenance would be required to free the structures from silting in, debris, and vandalism. The slab with legs was the only promising structure.

Effects Of Fertilizers On Cultured Salt Marsh Plants, Ruppia And Chara, Scott Marshall Stenquist

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 …

Water Resources Planning, Social Goals, And Indicators: Methodological Development And Empirical Test, Henry P. Caulfield

Reports

A methodology for comprehensive evaluation of water resources development and use (Techcom) has been developed and partially field tested. A model of societal goals consists of nine primary goals successively articualted into increasingly specific subgoals. Achievement of subgoals is perceived as affected by measurable social indicators whose values are perturbed by water resources actions. Linking the elements of the goals taxon by connectives result in an evaluation system. historical, political and philosophical considerations of the proposed system are discussed in Part I. Part II describes the results of the Rio Grande of New Mexico test including public perception and weighting …

An Analysis Of Water Research Programs Of The Utah Water Research Laboratory And Center For Water Resources Research, Water Resources Research Citizen Advisory Panel

Reports

Foreward: As a means of keeping water research programs at Utah State University responsive to needs in terms of both timeliness and emphasis, President Glen L. Taggart, in 1970, requested a number of Utah citizens to serve as a panel to give counsel and advice to the Utah Water Research Laboratory and Center for Water Resources Research. Membership of this 16-member panel represents a broad spectrum of water-related experience gained from a variety of professional backgrounds and organizational affiliations. The objective was to keep the panel small enough for it to be a "working" group but large enough to obtain …

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 …

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 …

A Study Of The Effectiveness Of Water Resources Planning Groups A Final Report, Daniel H. Hoggan, Jim Mulder, Sarah Jane Taylor, Dennis E. Oaks, Brent Somers, Raymond L. Richardson

Reports

Information and recommendations were developed pertaining to the organization of regional and river basin water planning studies, useful to river basin commissions and others responsible for such studies. The approach that was used included four basic components: (1) conceptualization of a planning model, based on an analysis of planning theory and organizational literature, (2) analysis and review of historical trends in water resources planned, (3) examination and comparative evaluation of 15 river basin planning studies, and (4) case studies of two planning efforts selected from the 15 examined in order to perform a more detailed analysis and to gain information …

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 …
