Evaluation Of Runoff Coefficients From Small Natural Drainage Areas, Carlos Fix Miller, L. Douglas James

KWRRI Research Reports

The Kentucky Department of Highways, as do most other agencies which build small drainage structures, estimates flood peaks as the product of a runoff coefficient, a rainfall intensity, and the drainage area, Available procedures were applied to 39 gaged watersheds in and near Kentucky and compared with the results of frequency analysis of historical stream gage records. The methods consistently underestimated the flood peak.

Therefore, a more intensive study (using the Stanford Watershed Model) of the runoff coefficient was undertaken by dividing it into overland flow and streamflow components. A set of curves was developed based on the 50-year event …

The Effects Of Geographical And Climatic Setting On The Economic Advantages Of Alternative Flood Control Measures, Clyde R. Dempsey, L. Douglas James

KWRRI Research Reports

It has long been realized that tributary urban development and channel improvement greatly affect the flow regime in a given watershed. A previous study used the Stanford Watershed Model to derive relationships expressing how the flood peaks in Sacramento, California, might be expected to vary with changing conditions of urbanization, channelization, and tributary drainage area. In order to observe the effects of climatic setting and geographical location on these relationships, the same type of analysis was applied to a drainage area near Louisville, Kentucky.

If reservoir storage is to be considered in a flood control program, it is necessary to …

Survival, Growth, And Food Habits Of Brook Trout Introduced Into An Eastern South Dakota Stream, Larry W. Kallemeyen

Electronic Theses and Dissertations

Brook trout were introduced into the South Fork Yellow Bank River, an eastern South Dakota stream, on October 11, 1966. A supplemental brook trout plant was made on June 8, 1967. Survival for the initial plant from October, 1966 through October, 1967 was 2.4%. Survival for the supplemental plant from June, 1967 through October, 1967 was 21.0%. Trout from both plants took part in spawning activities during the fall of 1967. Average length of trout from the initial plant increased 9.8 cm during one year. Their average condition factor reached a peak in June, 1967 after being low throughout the …

Movements And Behavior Of Pheasants During The Breeding Cycle As Determined By Radio-Tracking, Thomas L. Kuck

Electronic Theses and Dissertations

Behavior and movement studies were carried out on the Rifle-Calahan Study area, Sanborn County, South Dakota, in 1965 and 1966. Objectives of the study were to evaluate radio telemetry techniques, determine the territorial area and home range of the hen and cock, study the behavior pattern of hen and cock in the harem makeup, determine the distance traveled by the hen when attracted to the harem, determine if the hen nests in the immediate area of the crowing territory, and study the behavior of the hen while nesting and caring for the brood. Twenty adult pheasants (16 hens and 4 …

Ecological Relationships Of Breeding Blue-Winged Teal To Prairie Potholes, Roderick C. Drewien

Electronic Theses and Dissertations

Ecology and behavior of breeding blue-winged teal (Anas discors) were studied in northeastern Day County, South Dakota in 1965 and 1966. Breeding pair use of the wetland habitat and importance of Type 1 ponds in the wetland complex were evaluated. Pair densities of 30.7 and 33.0 per square mile in 1965 and 1966, respectively, were above the 16-year average from 1950-66 and near maximum. Blue-winged teal comprised 46.7 percent of the waterfowl breeding population in 1965 and 51.7 percent in 1966. Number of water areas per square mile through mid-spring 1965 was comparable to the average for the 16-year period …

Esthetic And Recreational Potential Of Small Naturalistic Streams Near Urban Areas, John A. Dearinger, Kenneth R. Harper, L. Douglas James

KWRRI Research Reports

The purpose of this study was to find a way to evaluate the esthetic and recreational potential of small streams and their watersheds. Research was limited to naturalistic streams with drainage areas under 100 square miles and located within 25 miles of a city. A methodology, based on some previous work of the U.S. Soil Conservation Service and the principles or concepts of terrain analysis, land use planning, value Judgment philosophy and the economics of outdoor recreation, was developed and applied in detail to two streams (Boone and Jessamine Creeks) near Lexington, Kentucky.

Evaluations were made of the streams' potential …

Some Ecological Observations On The Fathead Minnow, Pimephales Promelas, In The Alkaline Waters Of Nebraska, D. B. Mccarraher, Robert Thomas

Nebraska Game and Parks Commission: Staff Research Publications

Populations of the fathead minnow, Pimephales promelas, were apparently common throughout the sandhills region of Nebraska, prior to the appearance of the first pioneers, for Aughey (1880) listed the species as part of the native fauna. Current data relating to the distribution (Figure 1) and gross ecology of the species throughout the sandhills, was first collected in 1954 by the authors, with continuous observances recorded since that year. The fathead minnow is a common species throughout the northern great plains and appears to reach its greatest abundance in the shallow, alkaline lakes of Nebraska. Our investigations over the past …

Distribution And Mortality Of Saskatchewan-Banded White-Fronted Geese, Harvey W. Miller, Alex Dzubin, John T. Sweet

Nebraska Game and Parks Commission: Staff Research Publications

At its annual spring meeting in 1959 the Technical Committee of the Central Flyway Council recognized a decreased population of the white-fronted goose (Anser albifrons). The recorded harvest in Canada and the United States had exceeded the estimated wintering population in some years. After summarizing records for the Central and Mississippi Flyways the Committee found them inadequate for management and to help fill this void, recommended banding on local concentration areas including Saskatchewan.

Ecological Relationships Of Wetlands To Ring-Necked Pheasants In Nebraska, William L. Baxter, Carl W. Wolfe

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

Ecological relationships of ring-necked pheasants with rainwater basins were studied on a nine-section study area in south-central Nebraska.

Nesting studies conducted from 1960 through 1964 revealed the importance of vegetation complexes associated with wetlands as nesting cover. During the five-year period, 25 percent of all nests were initiated in this covertype, and 25 percent of all chicks were produced in this covertype. The wetlands also provided high quality brooding, loafing, roosting, and winter cover.

Human activities have destroyed 83 percent of the 3,909 wetlands in the rain basin area. The greatest loss occurred in smaller basins. Acreages in the basins …

Coleambally Irrigation Area: Herds, Crops, Fruit, Lydia Belthuis

Journal of the Minnesota Academy of Science

Coleambally, a new irrigation unit, to the south of the Murrumbidgee Irrigation Area in Australia, has come into operation since 1960. It is the first land to receive water from the large Snowy Mountain power and water storage development in southeastern New South Wales. This district of some 139,000 acres now produces rice, wheat, hay, vegetables, fat lambs and wool. When all Snowy Mountain structures are completed and reservoirs filled, the irrigation area will be more than tripled in size.

Multiple Cropping Will Increase The Erosion Hazard, W J. Burdass

Journal of the Department of Agriculture, Western Australia, Series 4

WITH the low price of wool and the price of wheat high in comparison, farmers need little encouragement to increase their acreage of crops.

Unfortunately with increased cropping comes the risk of increased erosion—unless there is a simultaneous increase in the use of conservation practices.

Private Irrigation Systems : Do They Pay?, G D. Oliver

Journal of the Department of Agriculture, Western Australia, Series 4

WESTERN AUSTRALIA, with 71,000 acres under irrigation, can hardly claim to have an important irrigation farming industry.

However, irrigation is daily growing in importance, especially through private schemes. These account for almost half the present irrigated area.

Urban Geology—A Need And A Challenge, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

Urban land uses are rapidly converting open land into intensively used land. Generally, in planning those uses, a comprehensive study has included everything except an evaluation of the land in three dimensions. Geologists are eminently well equipped to supply the missing data, but they must also be aware of the needs of the urban community and the kinds of information needed by planners if they are to write reports usable by planners. Urban and environmental geology is a newly expanding field in the use of geologic data to help solve some urban problems in the planning stage. It is likely …

A Study Of The Removal Of Pesticides From Water, James David Whitehouse

KWRRI Research Reports

The purpose of this study was to investigate some of the properties of pesticides as they exist in water, and to determine the effectiveness of several water treatment processes in the removal of pesticides from water. Among the pesticides investigated were malathion, DDT, aldrin, dieldrin, captan, benzene hexachloride (BHC), 2,4-D, and 2,4,5-T. The water treatment processes included aeration, chemical coagulation, adsorption on activated carbons and clays, and foam separation.

The removal of pesticides from water by aeration was found to be significant. Dieldrin was removed almost 100 percent, while aldrin, DDT, and BHC were removed to a lesser extent. 2, …

The Occurrence And Distribution Of Methane In The Marine Environment, Larry P. Atkinson, Francis A. Richards

CCPO Publications

The distributions of methane dissolved in the sulfide-bearing waters of the Black Sea, the Cariaco Trench, and Lake Nitinat are reported. The gas was not detected in the oxygen-deficient water of the eastern tropical Pacific Ocean, in the Santa Barbara Basin, nor in the sulfide-bearing water of Saanich Inlet. Maximum concentrations observed were 70 μmole CH4/l., and the distribution tends to follow that of sulfide. The data indicate that methane is derived from organic compounds not containing nitrogen or phosphorus and that its formation is much slower than that of sulfide. The solubility coefficient in seawater (salinity = 40‰) is …

Water Quality Study Of Lake Mead, Dale A. Hoffman, Paul R. Tramutt, Frank C. Heller, Bureau Of Reclamation

Publications (WR)

This report presents Lake Mead Water quality data obtained from 1964 to 1966. The effect of filling Lake Powell on the water quality of Lake Mead is evaluated. General limnological principles and the present limnology of Lake Mead are discussed. Lake Mead has a warm monomictic annual temperature cycle characterized by summer stratification, fall overturn leading into a continuous circulation throughout the winter; temperatures never fall below 39 deg F (4 deg C). During stratification, lower dissolved oxygen values were recorded in the thermocline than in the epilimnion and hypolimnion. Mineral content increases from the upper to the lower end …

A Noteworthy Record Of The Swift Fox In Mcpherson County, Nebraska, Lawrence J. Blus, Glenn R. Sherman, John Henderson

Nebraska Game and Parks Commission: Staff Research Publications

An adult female swift fox (Vulpes velox) was killed by an automobile 1 mile E Ringgold, McPherson Co., Nebraska, on 25 March 1966. Standard external measurements (mm) of this specimen are: 723, 275, 132, 59, and weight, 2000 g. This record is approximately 80 miles south of the nearest occurrence listed by Jones (Univ. Kansas Publ., Mus. Nat. Hist., 16: 1-356, 1964) and appears to be the first verification of the occurrence of this fox in the Nebraska Sandhills, although specimens have been taken on all sides of this area. Jones (1964) indicated that this species may have …

This report presents the results of definite plan studies of the Southern Nevada Water Project in Clark County, southeastern Nevada. Construction of this project was authorized under Public Law 89-292 dated October 22, 1965. Authorization of the Southern Nevada Water Project was based on a project plan outlined in the feasibility report of August 1963 as supplemented in April 1965. The definite plan studies have confirmed the general project plan of the 1963 report as supplemented but some important modifications are now contemplated as explained in Part IV.

The project will be constructed in three stages. Stage development is desirable …

Water Resources Of Tacoma, Washington, Richard Martin Glaser

Graduate Student Research Papers

This study explores the fresh water and hydroelectricity resources of the City of Tacoma, Washington. The history and development of the water supply and hydroelectric facilities is examined. One can see that the development of the water resources has been directly affected by the growth in population and industry and that the nearness to the city of development sites has been an aid in this development. With the amount of water available at present and the increase in hydro-electric facilities during this decade, the future outlook for Tacoma in the field of water resources seems bright.
