Natural Salinity Removal Processes In Reservoirs, Jay J. Messer, Eugene K. Israelsen, V. Dean Adams

Reports

A small but significant amount of salinity removal has been reported by various authors to occur in mainstem Colorado River reservoirs. Recalculation of some of these salinity budgets, together with a review of the data bases used, usggests taht removal has not often been conclusively demonstrated. Laboratory microcosm experiments and field data indicate that calcium carbonate precipitation, perhaps with some coprecipitation of magnesium carbonate, is the mechanism responsible for most of the salinity removal in Oneida Reservoir, Idaho. Coprecipitation processes (including ion exchange), coagulation, and bioassimilation do not appear to be important natural salinity removal mechanisms. Finally, loss of calcium, …

Televised Trials: Past And Present, Grant Greer

Undergraduate Honors Capstone Projects

In the early fifties, the television media sought to cover criminal trials with television cameras. A few states allowed some television coverage, but they were a minority. One of these states, Texas, made constitutional history when it allowed the television coverage of the criminal trial of Billie Estes in 1962. The case had been appealed all the way to the Supreme Court, where his conviction had been reversed because of the television coverage of his trial. The Supreme Court's holding in that case had been rather ambiguous because one justice in the five - man majority, while agreeing with the …

Fielding Ditch Pipeline Computer Simulation Study, Calvin G. Clyde, J. Paul Tullis, Roland W. Jeppson

Reports

The Fielding Ditch Company Pipeline is almost 3 miles long and supplies irrigation water under low pressure to adjacent fields through 33 turnouts along its length. The 24-inch non-reinforced concrete pipeline began to experience repeated structural failures soon after it was placed in operation. This study was done for the Soil Conservation Service by the Utah Water Research Laboratory to gather field data on the pipeline operating characteristics, to analyze the hydraulic transients in the pipeline with the help of a computer simulation model, and to suggest modification to protect the pipeline from future failures caused by transient pressures. Following …

The Potential For Groundwater Contamination Along Basin Margins In The Arid West: Alluvial Fans And Lake Features, Calvin G. Clyde, Robert Q. Oaks, Peter T. Kolesar, Edward P. Fisk

Reports

Many towns of the arid west were built upon alluvial fans and upon sites underlain by Pleistocene lake deposits. The objective of this study was to assess the potential impact of these activities of man upon groundwater quality within these geological features. Emphasis was placed on shallow groundwater quality after it was determined that deep groundwater is rarely contaminated at such sites. A reconnaissance of Utah and Nevada was made and four sites underlain by alluvial fans (Willard, Manti, Elsinore, and Spring City) and four sites underlain by lake shore deposits (Hyde Park, Fielding, Providence and Richmond) were selected in …

Water Quality In Pleasant Valley, Utah, Calvin G. Clyde, Dennis B. George, Kun Mo Lee, Phil Pucel, William Hay

Reports

Pollution of shallow groundwater due to wastewater disposal in Pleasant Valley, Utah, was investigated from October 1979 through August 1980. Water samples were collected from 23 wells and 5 stream sampling sites. Water quality analysis revealed pollution at several sites. Groundwater pollution caused by man’s activities in the area was observed in Bolotas and Scofield Campsite subdivisions. Severe shallow groundwater pollution measured in wells which were located in south and north profiles of the town of Scofield, Utah, could have originated from the municipal waste disposal practice in the town. Natural phenomena, however, such as pyrite oxidation, could possible have …

A very wide range of hazards to groundwater quality was found to exist. These cases cover the range …

Plant Protection As A Consequence Of An Ant-Membracid Mutualism: Interactions On Goldenrod (Solidago Sp.), Frank J. Messina

Biology Faculty Publications

In central New York, two chrysomelid beetles, Trirhabda virgata and T. borealis, frequently cause severe defoliation of tall goldenrod, Solidago altissima. This plant is also the primary host of Publilia concava (Membracidae), a sap—feeding treehopper that is tended by ants, especially Formica spp. Staged encounters indicate that Formica ants attack adult Trirhabda beetles on goldenrod stems bearing membracids. Such stems escape defoliation by Trirhabda, and show greater mean height increment and seed production than their nearest neighbors without ants. The degree of plant protection depends on the duration of Formica presence. During Trirhabda outbreaks, only stems bearing Formica ants for …

Ute Self-Determination In Setting Tribal Resource Development Policy, Herbert H. Fullerton, Mac Mckee, Roger D. Hansen

Reports

The Ute Indian Tribe of northeastern Utah has large land holdings rich in water and energy resources. Revenues from these sources have created capital that can potentially be used by the Tribe to further develop its resources and expand its agricultural and business enterprises. Realities, however, complicate this simple scenario in that the Tribal goals are broader than pure economic gain and that increased incomes may mean sacrifices in terms of these other goals. The Tribe faces the problem of how best to develop its water resources in a way that best meets its multiplicity of needs.

Vegetation Of Subalpine And Alpine Moraines In The Teton Range, Grand Teton National Park, Wyoming, John R. Spence

Biology

The vegetation on the neoglacial deposits below six glaciers in Grand Teton National Park was examined. The deposits at the six sites range from large terminal moraines to steep debris slopes to relatively flat debris accumulations. The sites are characterized by a diversity in topography, climate, and aspect. The environmental millieu the plants are occupying is dominated by disturbance, including mass-wasting, climatic fluctuations, and possible herbivory. One hundred and four species of vascular plants were collected from the six sites. Most of these are typical arctic-alpine species. Transplants of late successional species failed to survive because of dessication, snow kill, …

Antipredator Behavior And Parental Care In The American Avocet And Black-Necked Stilt (Aves: Recurvirostridae), Tex Albon Sordahl

Biology

Free-living American Avocets and Black-necked Stilts were studied during 1977 and 1978 in northern Utah. The broad objectives of the study were to: (1) describe the breeding biology of the birds and identify aspects related to predation pressure, and (2) examine the antipredator behavior of parent birds and their young. Nest success was approximately 30% at 75 avocet and 18 stilt nests studied. Fifty-seven percent of nest failures were due to predation on eggs, and another 11% were due to predation on incubating adults. Juvenal-plumaged broods contained fewer chicks than downy broods, indicating partial brood loss, which was probably due …

Irrigating For Rainbows, Jack Keller

Faculty Honor Lectures

Quite simply. irrigation is the act of applying water to land. It is usually done to improve plant growth and it lies somewhere between an art. a science. and plain hard work. Even though we do not often think about it. irrigation is very important to the well-being of the world. It is important because we need basic foods to survive. and luxury foods and pleasant views to enjoy this survival. For the many people directly involved in irrigation. especially farmers. it provides a livelihood which is both satisfying and peaceful. And for the few of us lucky enough to …

A Survey Of Selected Employers And Placement Counselors To Determine Sociocultural Factors In The Work Adjustment Of Navajo Students In Box Elder County, Utah, Dolores M. Keller

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

The primary goal of vocational education is to prepare the student to successfully enter the world of work. While the present educational structure seems to work well for most Anglo-American students, there is evidence that the system is not effective with minority students. For example , in the case of Navajo students in government-sponsored technical schools, the dropout rate (60 percent) suggests that for Native American students there are serious problems in the educational process which need to be investigated and understood.

Because of the sharply different cultural background of the Navajo student a formidable barrier frequently exists between student …
