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 …

The Effect Of Human Activity On The Middle Course Of The Tualatin River, Oregon, Lolita M. Carter

Dissertations and Theses

A diurnal study of biological, chemical, and physical parameters was made on the middle course of the, Tualatin River, which drains a 1840 km² (711 mi²) basin adjacent to metropolitan Portland, Oregon. This portion of the river lies along land in transition of use from rural agriculture to highly urbanized development.

There is no nutrient loading of the river from farming practices because there was no return of water from summer, sprinkler irrigation of commercial crops. However, irrigation significantly reduces the volume of water in the river in the summers.

Heat And Moisture Conduction In Unsaturated Soils, J. A. Havens, R. E. Babcock

Arkansas Water Resources Center Technical Reports

Mathematical models are developed for the prediction of heat transfer from hot water pipes buried in the soil. Heat transfer in the absence of moisture transfer is described as a function of the difference between the temperature of the pipe and the temperature of the soil surface. The energy balance is used to determine the longitudinal temperature distribution of the water. The method is extended to describe a system of equally spaced, parallel buried pipes. Soil temperature profiles around the pipes are presented. The model is used to calculate the land area that can be heated by an underground piping …

Evaluation Of Recovery In A Polluted Creek After Installation Of New Sewage Treatment Procedures, Robert A. Kuehne

KWRRI Research Reports

Response of Hickman Creek near Lexington, Kentucky to alleviation from serious sewage pollution was studied from January, 1973 through July, 1974. Wastes are now handled from an efficient secondary treatment facility and four sequential polishing lagoons before chlorination and discharge to West Hickman branch.

Physico-chemical tests gave no strong indication of residual pollution effects at the start of the study, approximately six months after the treatment facility opened. At low flow a slight oxygen sag, probably associated with algal growth in the lagoons, persists downstream from the outfall. Mean values for turbidity, nitrates and COD are somewhat higher at the …

Respiratory Metabolism And Energy Requirements Of Embryo, Larval And Juvenile Mountain Whitefish, Prosopium Williamsoni, Pokkavil Karunakara Rajagopal

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The upper optimum temperature for embryonic development of mountain whitefish is 6 C, and for the post yolk sac stage is 9 to 12 C. The need to know effects on all stages in the life cycle in cases of thermal pollution is demonstrated. Abnormalities caused by thermal pollution in hatched larvae were agape jaws, coloboma or fissure of the eye, monophthalmia or the presence of only one eye, monomicrophthalmia or the presence of one small eye and one case of twinning. High mortalities of eggs occurred at 9 C and higher.

Nutritional Quality And Herbage Production Of Intermediate Wheatgrass (Agropyron Intermedium [Host] Beauv.) When Infested With Black Grass Bugs (Labops Hesperius Uhler), Alan M. Gray

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two intermediate wheatgrass seedings with different levels of grass bug infestation were evaluated for herbage production, seedhead production, percent dry matter, crude protein, and cell contents. Study sites were located at different elevations on mountain summer ranges in northern (Site I) and central (Site II) Utah. Study plots at Site I and Site II were infested with 113 and 210 bugs per sweep, respectively. Herbage production appeared to be reduced in early spring on the site with the higher infestation; however, no effect on season-long herbage production could be detected on either site. Seedhead production on infested plots was reduced …

Factors Influencing Germination And Seedling Survival Of Several Varieties Of Astragalus Lentiginosus Dougl., Paul Ziemkiewicz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Astragalus lentiginosus, which consists of 36 varieties, is one of the principal locoweeds of western North America. The objectives of this study included identification of some of the major factors affecting germination of the seed and survival of the newly established seedlings for several of these varieties.

The seeds of the varieties studied exhibited two mechanisms for dormancy. One is a seed coat that is impermeable to water, and the other is a water-leachable inhibitor. The presence or absence of low-intensity incandescent light (in 14-hour day lengths) had no effect on germination. Of three temperature regimes studied, the regime …

Exploratory Sensitivity Analysis Of A Stream Ecosystem Model, Joseph H. Wlosinski

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The framework of a stream ecosystem simulation model is described. Using this framework and data from two different geographical areas, a cold desert stream and a generalized mountain stream, exploratory sensitivity analysis was performed on the model. This was accomplished by qualitatively comparing outputs of a series of simulations in which a different level of a driving variable was used in each simulation. Based on these results, recommendations are made for improving the structure of the model.

Gas Exchange And Water Relations Of Two Alpine And Two Arctic Tundra Plant Species, Douglas Allan Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Although water stress is an important selective force in many environments, it is not commonly considered to be of particular importance in tundra areas. Even though large portions of tundra may have an abundance of water, other more exposed areas may become quite dry. This microsite variability with respect to moisture stress was reflected in soil water potential measurements obtained from an alpine tundra area on Niwot Ridge in Colorado. Even though soil water potentials were consistently above -5 bars in a relatively low lying Deschampsia meadow, soil water potentials from an exposed fellfield area were often as low as …

The Influence Of Roots On The Accuracy Of Soil-Moisture Measurements Taken With A Neutron Moisture Meter, Terry L. Andreessen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effects of roots on soil-moisture measurements taken with a neutron probe were studied. These effects were observed under three different soil-moisture conditions, with different sized roots, and with varying distances between the access tube and root. The moisture conditions used were air dry, field capacity, and saturated.

Large roots can greatly affect neutron soil-moisture measurements when the access hole is drilled through the root. Positive errors as large as 52 percent were found when the soil moisture was at field capacity. With dry and saturated conditions positive errors of 43 percent and 38 percent respectively, were found.

In most …

Water Quality Impact Of Burning And Grazing On A Chained Pinyon-Juniper Site In Southeastern Utah, John C. Buckhouse

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During 1973 and 1974 a water quality study was conducted in San Juan County, southeastern Utah. In 1973, baseline water quality data was collected from study locations which had been chained to remove pinyon-juniper vegetation six years earlier. The area had been chained under two different techniques: (1) doubled chained, with debris-left-in-place and (2) chained, with debris windrowed. An "undisturbed, natural" woodland was left between these two treatments in order to serve as a control area.

In the fall of 1973 and spring of 1974 secondary treatments of burning and grazing were superimposed upon the debris-in-place and windrowed sites, respectively. …

Maritime Environment: A Systems Approach, Peter A. Roche

Marine Affairs Theses and Major Papers

Some maritime activities may be independent of each other but most are in competition and some are supportive in one way or other with most other maritime activities. Fisheries and merchant vessels rarely are at odds over matters of ocean traffic. However, both those activities may object to obstructions related to offshore oil drilling. Both municipalities and fisheries complain of merchant vessel pollution. Companies of different, states compete for offshoreoil lease rights. On the other hand, synergy and sublimation sometimes result from interworkings of maritime activities. Complexes of offshore platforms increase fish congregations. Powerplant cooling ponds transmute thermal pollution into …

The Deepwater Port Act Of 1974, James C. Moses

Marine Affairs Theses and Major Papers

During the past two years of the 93rd Congress, no less than eleven different bills were introduced to deal with the various aspects of deep-water port development. Much has been made of the supposition that with energy conservation, higher petroleum prices, import quotas and all the other gas-saving ideas in vogue, deepwater ports have become an anachronism of pre-energy crisis days, the days of world-scale 400 in tankers and dreams of million-ton ULCC's. The truth of the matter is that we shall still, for an indeterminate period, require imported oil, by the dictum of economics, it will come via the …
