Digital-computer model of the principal ground-water reservoir in Beryl-Enterprise area, Escalante Desert, Utah
R. W. Mower, Scott D. Bartholoma
1981, Open-File Report 81-532
The computer model presented in this report was used to simulate the principal ground-water reservoir in the Beryl-Enterprise area, Escalante Desert, Beaver, Iron, and Washington Counties, Utah (Mower, 1981). The details of the formulation of the model, testing of its validity, and the results of predictions are discussed in the...
Ground-water data for the Beryl-Enterprise area, Escalante Desert, Utah
R. W. Mower
1981, Open-File Report 81-340
This report contains a compilation of selected ground-water data for the Beryl-Enterprise area, Iron and Washington Counties, Utah. The records of the wells include such information as driller's logs, yield, drawdown, use, and temperature of the well water. There are also records of water levels in selected wells for the...
Selected biological characteristics of streams in the southeastern Uinta Basin, Utah and Colorado
Ronald W. Naten, Richard H. Fuller
1981, Open-File Report 81-644
Biological sampling was carried out during 1976-78 in five streams in the southeastern Uinta Basin, Utah and Colorado, in order to provide baseline water-quality data for an area of potential oil-shale development. The biological activity in the streams sampled generally is limited by physical factors more so than by chemical...
Ground-water reconnaissance of part of the lower Kenai Peninsula, Alaska
G.L. Nelson, P.R. Johnson
1981, Open-File Report 81-905
Most residential and industrial development of the Lower Kenai Peninsula, Alaska, is along the coast of Cook Inlet. Most of the information about subsurface conditions is obtained from wells along the coast. Ground water is recharged by local precipitation, and slow drainage of ground water to the streams maintains streamflow...
Hydrology and the effects of industrial pumping in the Nikiski area, Alaska
Gordon L. Nelson
1981, Open-File Report 81-685
Ground-water consumption for industrial use at Nikiski increased from about 1 million gallons per day in 1968 to 4.2 million gallons per day in 1979. Water managers and local citizens are concerned that industrial pumping may reduce the esthetic and recreational value of local lakes. Some lake levels have declined...
Directory of member organizations of the National Water Data Exchange (NAWDEX)
Janet M. Nokes, Cassandra D. Blackwell
1981, Open-File Report 81-497
The National Water Data Exchange (NAWDEX) is a national confederation of water-oriented organizations working together to improve access to water data. It consists of member organizations from all sectors of the water-data community. This Directory provides the names, addresses, and telephone numbers of all NAWDEX member organizations and their designated...
Toxicity of Mount St. Helens ash leachate to a blue-green alga
Diane M. McKnight, Gerald L. Feder, Eric A. Stiles
1981, Circular 850-F
During several periods of volcanic-ash eruption at Mount St. Helens, Wash., (March 30, May 25-26, May 30-June 2, and June 12-13, 1980) strong winds from the north occurred at high altitudes. As a result, the volcanic ash fell some 50 miles to the south in the Bull Run watershed, the...
A model for simulation of flow in singular and interconnected channels
Raymond W. Schaffranek, R.A. Baltzer, D.E. Goldberg
1981, Techniques of Water-Resources Investigations 07-C3
A one-dimensional numerical model is presented for simulating the unsteady flow in singular riverine or estuarine reaches and in networks of reaches composed of interconnected channels. The model is both general and flexible in that it can be used to simulate a wide range of flow conditions for various channel...
