Potential flood and debris hazards at Cottonwood Cove, Lake Mead National Recreation Area, Clark County, Nevada
Otto Moosburner
1981, Open-File Report 80-1216
At Cottonwood Cove, Nevada, most of the existing dikes at the recreation sites are effective in diverting and routing floodflows, up to and including the 100-year flood, away from people and facilities. The dikes across Ranger Residence Wash and Access Road Wash at the mouth divert floods up to the...

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...

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...

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

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...
