Measurement Of Currents In Lake Mead With The Deep Water Isotopic Current Analyzer (Dwica), J. J. Sartoris, D. A. Hoffman, Bureau Of Reclamation

Publications (WR)

In Nov 1967, a Deep Water Isotopic Current Analyzer (DWICA) was used to study current patterns in the Boulder Basin of Lake Mead to determine if low-quality water from Las Vegas Bay might enter the Southern Nevada Water Project intake on Saddle Island. Secondary objectives were to study the general current patterns in Boulder Basin and the effect of power discharges at Hoover Dam on these currents. Results of current measurements at 3 stations in Boulder Basin are given. Observations indicate a definite possibility that low-quality water from Las Vegas Bay might enter the water intake on Saddle Island. Current …

Sevier River Basin Floods 1852-1967, United States Department Of Agriculture, Economic Research Service, Forest Service, Soil Conservation Service Sep 1971

Sevier River Basin Floods 1852-1967, United States Department Of Agriculture, Economic Research Service, Forest Service, Soil Conservation Service

Elusive Documents

This chronology of Sevier River Basin floods extends from 1852 to

1967. Most common and destructive are dry mantle floods, which flow as

a muddy mortar-like substance containing 40 to 55 percent water. Hundreds

of tons of protective topsoil are removed from watershed lands,

debris and boulders are picked up as the flow travels down steep stream

channel gradients, and then the flood is debouched into communities and

on to productive cropland.


Analysis Of Water Reuse Alternatives In An Integrated Urban And Agricultural Area, A. Bruce Bishop, David W. Hendricks Sep 1971

Analysis Of Water Reuse Alternatives In An Integrated Urban And Agricultural Area, A. Bruce Bishop, David W. Hendricks

Reports

Intoduction

The growing demands on our existing water supplies and the current problems of water shortage emphasize the need for a comprehensive approach to analysis and planning of water reuse. The primary focus, heretofore, has been on the treatment technology for achieving water reuse.

The concept of reuse, however, should be broadened to consider a totally integrated urban and agricultural system. This necessitates a systems analysis where water reuse, together with all other water dispositions, is considered in the context of its contribution to the total water resources pool of a region.

The components of the water resource system are …

Interim Report On Water Quality Investigation Degray Reservoir, Arkansas, J. Nix Jul 1971

Interim Report On Water Quality Investigation Degray Reservoir, Arkansas, J. Nix

Technical Reports

Impoundment of the Caddo River near Arkadelphia, Arkansas began in August, 1969. Detailed patterns of the dissolved oxygen distribution in this reservoir are presented for the period September, 1969 through April, 1971. Although the reservoir had not reached normal pool elevation, thermal stratification accompanied by severe hypolimnic oxygen depletion has been observed. The dissolved oxygen data show that an under flow occurs in the fall of the year and carries dissolved oxygen into the hypolimnic zone. The gradients of dissolved oxygen concentration observed during the winter indicate that the reservoir does not undergo complete mixing. A short summary of the …

Unsteady Flow Toward Partially Penetrating Artesian Wells, Y. H. Huang Jun 1971

Unsteady Flow Toward Partially Penetrating Artesian Wells, Y. H. Huang

KWRRI Research Reports

A numerical method programmed for a high-speed computer was developed for determining the drawdown around an artesian well. A salient feature of the program is that it can be used for both fully and partially penetrating wells in either infinite or finite aquifers. The method Involves the application of finite difference equations to the well-known heat equation using a graded network. A comparison of the finite difference solutions with those obtained from the close-form formulas of Muskat, Theis, and Hantush indicates the validity of the method. A comparison between the finite difference solutions and the drawdowns measured on a sand …


Measuring The Intangible Values Of Natural Streams, Part I, John A. Dearinger, George M. Woolwine Jun 1971

Measuring The Intangible Values Of Natural Streams, Part I, John A. Dearinger, George M. Woolwine

KWRRI Research Reports

The purpose of this study was to apply the "uniqueness concept" to the quantification of the intangible values of natural streams. The methodology is based on procedures developed by Luna B. Leopold and Maria O. Marchand of the U.S. Geological Survey. It involves the evaluation of a set of characteristics or factors for selected stream sites. Each factor is rated for each site on a numerical scale indicative of the range of possible "values" for that factor. An "uniqueness ratio" (the reciprocal of the number of stream sites sharing a given category rating) is then computed for each stream for …

The Impact On The Navy Of Public Concern With Control Of Pollution Of The Seas By Oil, Robert Augustus Fisher May 1971

The Impact On The Navy Of Public Concern With Control Of Pollution Of The Seas By Oil, Robert Augustus Fisher

Marine Affairs Theses and Major Papers

It is difficult at best to evaluate the biological and chemical damages of oil pollution, but the physical effects are graphically evident in the blackened beaches and coastlines around the world and in the floating "tar-balls" found in mid-ocean. It is this dramatically visible effect that has stirred public concern. Thus, prevention of such damage is high on the list of priorities for both national and international concern. In the face of the ever increasing potential for pollution, President Nixon has pledged that federal agencies will take the lead in pollution abatement programs.

Spawning And Early Life History Of Largemouth Bass (Micropterus Salmoides) In Wahweap Bay, Lake Powell, Kent D. Miller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Spawning time and habitat of largemouth bass, survival of embryos, and growth and food habits of fingerlings were studied in 1968 and 1969 at Wahweap Bay, Lake Powell. Spawning began in mid- to late-April, when mean daily water temperature at nesting depths was 14.4-15.0 Centigrade (58-59 Fahreheit), and continued until mid-June. Most spawning took place on the northeast shore of the bay. Sandstone rubble was the most commonly used bottom type for nesting, either at the base of ledges or around large sandstone boulders. Mean nest depth increased from 1.63 meter to 4.54 meters (5.36 feet to 14.90 feet) in …


Telemetered Heart Rates Of Free-Living Uinta Ground Squirrels In Response To Social Interactions, Robert L. Ruff May 1971

Telemetered Heart Rates Of Free-Living Uinta Ground Squirrels In Response To Social Interactions, Robert L. Ruff

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Free-living Uinta ground squirrels (Spermophilus armatus) were instrumented with miniaturized ECG radio-transmitters to measure their short-term and long-term heart rate responses to social interactions. A continuous trapping and direct observation program prior to and during the study provided complete behavioral and life history information for virtually all ground squirrels on the 22-acre study area.

Three broad categories of heart rate information were obtained: responses by squirrels (1) in their burrows, (2) above ground during social interactions, and (3) above ground when animals were not fighting and when conspecifics were both absent and present.

Marked changes in the heart …

The Role Of Compulsory Sealanes In Resolving Multiple-Use Conflict On The Continental Shelf, Alfred P. Manning Apr 1971

The Role Of Compulsory Sealanes In Resolving Multiple-Use Conflict On The Continental Shelf, Alfred P. Manning

Marine Affairs Theses and Major Papers

An analysis of the nature of multiple-use conflict on the continental shelf developed with particular emphasis on the involvement of ocean transportation and offshore oil recovery. The wide-ranging effects which offshore marine accidents may have on coastal residents is discussed. Trends indicate a growth in the level of conflict stemming from competition between those wishing to use the same ocean space for the same purpose, the same ocean space for different purposes, and different but related ocean space for incompatible purposes. Ocean transportation is identified as the single common element in all three conflict categories. Restriction on traditional concepts of …


Oceanic Disposal Of Radioactive Wastes: Effects And Proposals, Billy M. Ervin Apr 1971

Oceanic Disposal Of Radioactive Wastes: Effects And Proposals, Billy M. Ervin

Marine Affairs Theses and Major Papers

An investigation of the effects of radioactive waste disposal into the oceans pursued by an examination of the hazards involved, the present sources of radioactive wastes and future prospects. The longevity of many radioactive elements, coupled with the awesome consequences to which even a slight miscalculation may lead, are convincing arguments for the most conservative approach to the problem of disposal of radioactive wastes. Present day disposal of radioactive wastes in the oceans, while significant, have not yet had major discernible effects on man or marine life. However, with the worldwide explosion of electrical power demand and the increasing use …

Management Of Natural Lakes In The Northern Great Plains, D. B. Mccarraher Apr 1971

Management Of Natural Lakes In The Northern Great Plains, D. B. Mccarraher

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

Approximately 2,800 natural lakes smaller than 10 acres in size are found in the northern plains region of Nebraska, South Dakota and North Dakota. Water quality characteristics vary greatly among lakes in close geographical proximity. They range from fresh to highly mineralized bicarbonate-carbonate-hydroxide (alkaline) to chloro-sulfate (saline) types and regionally represent the largest concentration of inland mineral waters in North America. Water quality together with shallow basin morphometry exert major environmental influences on the fisheries in great plains natural lakes.

In the sandhills region of Nebraska (20,000 sq. mi.) only about 45% of the estimated 1,400 natural lakes support fish …
