Trace Metal Analysis Of Barren River And Nolin River Reservoirs By Atomic Absorption Spectroscopy, Mary Jo Kennedy Jul 1969

Trace Metal Analysis Of Barren River And Nolin River Reservoirs By Atomic Absorption Spectroscopy, Mary Jo Kennedy

Masters Theses & Specialist Projects

This research was part of a project underway at Barren River and Nolin River Reservoirs in south-central Kentucky. The research was partially supported by a grant through the Sport Fishing Institute, Washington, D.C.

The study reported herein was concerned with the analysis of trace metal concentrations in the two reservoirs. It is believed that the fish population may in part depend upon the trace metals present in the water. It is anticipated that the data presented in this paper will eventually be correlated with the biology studies of the reservoirs being carried out by the Department of Biology of Western …

Solution Geochemistry Of The Water Of Limestone Terrains, John Thrailkill, David B. Beiter, Michael T. Osolnik, Roger H. Postley, William T. Mitchell, Leonard N. Plummer, James R. Riddell, Richard C. Worley, Robert D. Zwicker

KWRRI Research Reports

Limestone groundwater flows mainly in openings it has solutionally enlarged, thus an understanding of the water's state of saturation relative to calcite (the principal mineral component of limestone) is fundamental to an understanding of the nature and evolution of the limestone aquifer. This study investigated the Mammoth Cave-Sinkhole Plain (MCSP) and Cave Hollow (CH) aquifers in Kentucky, both in Missippian limestones.

Both aquifers were always undersaturated with calcite. Except for completely ventilated vadose flows (usually) and some vadose seepage (occasionally), all recharges sampled (sinking streams, vadose flows, and vadose seepage) were also undersaturated. The lack of saturation in the MCSP …

The Tiger's Back "A Report On Australian Organizations For Metropolitan Planning Administration", Robert D. Kuzelka Jan 1969

The Tiger's Back "A Report On Australian Organizations For Metropolitan Planning Administration", Robert D. Kuzelka

Conservation and Survey Division: Faculty and Staff Publications

The Australian town planning scene presents many interesting and unusual aspects to the city planner from the United States of America. Aspects which because of familiarity and proximity may not strike the Australian town planner as being either interesting, or unusual. This report will discuss some of these aspects as they seem to be affecting each major metropolitan region which includes the capital city in each of the six Australian States. Throughout the report, "metropolitan region" refers to the unit, or units of Local Government which are included in the planning area of each organization which is considered in this …

West Midlands Development : Water Supplies In The West Midlands, I A F Laing Jan 1968

West Midlands Development : Water Supplies In The West Midlands, I A F Laing

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

IF it is practical and economic to develop both surface and underground supplies, the aim on each farm should be to provide half the farm water requirement from dams, and the other half from bores.


The Effects Of Geographical And Climatic Setting On The Economic Advantages Of Alternative Flood Control Measures, Clyde R. Dempsey, L. Douglas James Jan 1968

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 …


Ground Water Flow Systems Of Central Nevada, G. William Fiero Jr Jan 1968

Ground Water Flow Systems Of Central Nevada, G. William Fiero Jr

UNLV Theses, Dissertations, Professional Papers, and Capstones

The U.S. Atomic Energy Commission has been evaluating a large area of central Nevada in order to define a supplemental test site for the underground testing of high-yield nuclear devices. Safety considerations involving the radiocontamination of the ground water in the vicinity of the test site necessitated that research be conducted to determine the direction and rate of flow of the ground water. This investigation defines the ground water flow systems in eighteen valleys comprising 12,000 square miles of central Nevada.

The definition of the systems was made following a compilation of existing hydrologic and geologic data for the area. …
