The Water Resources Division, U.S. Geological Survey, is charged with (1) maintaining a hydrologic network in Nevada that provides information on the status of the State's water resources and (2) engaging in technical water-resources investigations that have a high degree of transferability. To meet these broad objections, 26 projects were active in Nevada during fiscal year 1982 in cooperation with 36 Federal, State, and local agencies. Total funds were $3,319,455, of which State and local cooperative funding amounted to $741,500 and Federal funding (comprised of Geological Survey Federal and cooperative programs plus funds from six other Federal agencies) amounted to …

An Economic Valuation Of South Dakota Wetlands As A Recreation Resource For Resident Hunters, Craig W. Johnson

Electronic Theses and Dissertations

In spite of efforts to conserve wetlands, intensified agriculture, water projects, and urban development annually diminish the quantity and quality of wetland resources (Weller 1981). Leitch and Danielson (1979) noted that when the discounted value of the returns to drainage exceed drainage costs there is an economic incentive to drain. If present drainage rates continue, Weller (1981) estimated that most wetlands will disappear by the year 2140. Research has only recently focused attention on the need to estimate the public value of wetland benefits and the social costs of drainage (Leitch and Danielson 1979). The disparity between private and social …

Angler Harvest Survey Of Lake Francis Case, South Dakota, Lawrence M. Miller

Electronic Theses and Dissertations

An angler harvest survey, consisting of two independent surveys, was conducted on Lake Francis Case, South Dakota, from May through October 1981, and April through October 1982. An aerial angler count was used to estimate angle pressure, and an angler interview survey was used to estimate catch rate. In 1981, a section of Lake Francis Case in the vicinity of the Gregory County Pump Storage Project (Zone 2) was surveyed. IN 1982, the survey was expanded to include the entire reservoir (additional Zones 1 and 3). Estimated fishing pressure for Zone 2 in 1981 was 188,631 angler-hours and in 1982 …

Sediment Oxygen Demand In Streams Receiving Sewage Effluent, John J. Schultz

Masters Theses

Sediment oxygen demand is an important factor in determining dissolved oxygen concentrations in streams and rivers subjected to sewage effluents and other sources of organic pollution. Resuspension of sediments during bottom-scouring after periods of heavy precipitation exerts an immediate and increased oxygen demand on the water and is expected to decrease sediment oxygen demand at the site.

Sediment samples were collected monthly from April through November, 1983 from three small streams subjected to sources of organic pollution. The samples collected were arbitrarily categorized into wet and dry period samples based on the total precipitation between collection dates. Sediment oxygen demand …

Direct Filtration Versus Conventional Water Treatment In The Intermountain Region, Susan K. Burns, V. Dean Adams, Steel B. Maloney

Reports

The direct filtration water treatment scheme does not include sedimentation and in some cases flocculation. Compared to conventional treatment, direct filtration has lowered capital costs, reduced space requirements, decreased sludge quantities, and reduced coagulant dosages. One objective of this research was the statistical comparison of the direct filtration, Utah Valley Water Purification Plant (Orem, Utah) and the conventional Little Cottonwood Water Treatment Plant (Salt Lake City, Utah). These treatment plants are the two most compatible treatment plants having the highest correlation of source water in the local area. The Little Cottonwood plant receives approximately 65 percent of its sources water …

The Development Of Construction And Equipment Standards To Promote Tanker Safety And Pollution Prevention, Kathleen M. Daly

Marine Affairs Theses and Major Papers

Upstaged by a dramatic series of tanker accidents in the winter of 1976-77, the Carter Administration responded by meeting drama with drama - the President proposed a bold set of recommendations that, if adopted, would surely improve tanker safety but would, at the same time, impose considerable economic hardship on an already faltering tanker industry. The purpose of this study is to examine the specific construction and equipment requirements put forth in the Presidential Initiatives, as they later became known, and trace the modifications made to them before they were incorporated into the tanker safety laws of the U.S. and …

Changes In The Lower Chesapeake Bay Food-Chain In Presence Of The Sea Nettle Chrysaora-Quinquecirrha (Scyphomedusa), David Feigenbaum, Michael Kelly

OES Faculty Publications

The abundance of 4 levels of the lower Chesapeake Bay food chain (Chlorophyll a, herbivores, ctenophore Mnemiopsis leidyi, and Scyphomedusa Chrysaora quinquecirrha) were moni­tored twice weekly at 4 stations from May 10 through Sep 30, 1982 in the Lafayette and Elizabeth Rivers (Virginia). The herbivore standing stock, largely copepods, declined sharply in late May when M. Jeidyi appeared, but rebounded a month later when C. quinquecirrha medusae reduced the ctenophore population. Despite the additional presence of Aurelia aurita (Scyphomedusa) from Jul onward, herbivore abundance remained at moderate levels until the end of the study period. Phytoplankton abundance fluctuated …

An Evaluation Of Burrow Destruction As A Ground Squirrel Control Method, Dennis C. Stroud

Great Plains Wildlife Damage Control Workshop Proceedings

Several researchers have suggested that the presence of burrows is a limiting factor for ground squirrel populations and that the destruction of these burrow systems can reduce the rate of reinvasion following control. However, no one has yet tested the potential value of burrow destruction as a control method.

The Microcomputer And Kansas Wildlife Damage Reports, Martin Ottenheimer

Great Plains Wildlife Damage Control Workshop Proceedings

When F. Robert Henderson, the Extension State Leader of Kansas' Wildlife Damage Control Program, asked me for assistance in setting up a microcomputer system that would enable him to organize and analyze wildlife damage reports, I was surprised. "Certainly," I thought, "it's not because I am a social anthropologist and in my travels around the world I deal with some pretty wild life" No, Bob knew about my work with microcomputers in Anthropology and since we have been friends for some years he also knew that I would talk with him about the problems in using microcomputers. He also knew …

A Microsystem Sediment-Water Simulation Study For The Proposed Jordanelle Reservoir, Heber City, Utah, United States Department Of The Interior, Bureau Of Reclamation

Water

The technique of microsystem sediment-water simulation was used to predict water quality data for the proposed Jordanelle Reservoir, Heber City, Utah. Simulation microsystems were prepared for four sites located in the north arm of the reservoir basin including two sites located in an abandoned acid mine tailings pond. Data obtained from the tailings pond microsystems indicated that low pH water and high trace metal concentrations will exist in the north arm of the reservoir. These data suggested that some kind of membrane or compacted earth lining will be necessary to seal and contain the mine spoilage. Other sites in the …

The pipeline system characteristics and the method of slurry preparation also affects the overall water requirement of the system. In the present study methodologies are developed based on reported and modified coal slurry flow correlation equations to determine the quantity of water needed under various coal transport and flow conditions. Auxiliary water requirements including start-up and flushing water storage; related evaporation and seepage losses are also included. A computer program and several monographs are presented to provide a …

The Red River Gorge: The Existence Of "Recreational Niches" And Their Management Implications, Sara E. Alexander, Billie R. Dewalt, Eugenie Scott

KWRRI Research Reports

Until the late 1960's, the Red River Gorge was just one of the more beautiful parts of the Daniel Boone National Forest. At this time, the Army Corps of Engineers proposed to dam the river for flood control, water supply, and recreation purposes. Intense opposition to the project generated considerable publicity and the Gorge area experienced substantial increases in visitation. The result has been not only severe environmental degradation but extensive overcrowding as well. These trends are presently overtaxing management capabilities of the United States Forest Service. The most pressing issue has come to be how to effectively manage this …

Modeling Surface And Subsurface Stormflow On Steeply-Sloping Forested Watersheds, Patrick G. Sloan, Ian D. Moore, George B. Coltharp, Joseph D. Eigel

KWRRI Research Reports

A simple conceptual rainfall-runoff model, based on the variable source area concept, was developed for predicting runoff from small, steep-sloped, forested Appalachian watersheds. Tests of the model showed that the predicted and observed daily discharges were in good agreement. The results demonstrate the ability of the model to simulate the "flashy" hydrologic behavior of these watersheds.

Five subsurface flow models were evaluated by application to existing data measured at Coweeta on a reconstructed homogeneous forest soil. The five models were: Nieber 's 2-D and 1-D finite element models (based on Richards' equation), the kinematic wave equation, and two simple storage …
