Digital model of the Bates Creek alluvial aquifer near Casper, Wyoming
K. C. Glover
1982, Water-Resources Investigations Report 82-4068
A digital model was used to simulate ground-water flow within the Bates Creek alluvial aquifer, southwest of Casper, Wyoming. Hydrologic data collected during 1977 and 1978 were used to develop the flow model under steady-state and transient conditions. Three scenarios for operating the stream-aquifer system were evaluated with the digital...
Prediction of earthquake response spectra
W. B. Joyner, David M. Boore
1982, Open-File Report 82-977
We have developed empirical equations for predicting earthquake response spectra in terms of magnitude, distance, and site conditions, using a two-stage regression method similar to the one we used previously for peak horizontal acceleration and velocity. We analyzed horizontal pseudo-velocity response at 5 percent damping for 64 records of 12...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: September 1982
John B. Townshend, J.E. Papp, E.A. Sauter, L.Y. Torrence, T.K. Cunningham
1982, Open-File Report 82-300-I
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: April 1982

Annual peak discharges from small drainage areas in Montana through September 1981
R. J. Omang
1982, Open-File Report 82-270
Annual peak stage and discharge data have been collected and tabulated for crest-stage gaging sites in Montana. The crest-stage program was begun in July 1955 to investigate the magnitude and frequency of floods from small drainage areas. The program has expanded from 45 crest-stage gaging stations initially to 172 stations...
Effects of urban development on the aquifers in the Memphis area, Tennessee
D. D. Graham
1982, Water-Resources Investigations Report 82-4024
Ground-water withdrawals from aquifers in the Memphis area average about 190 Mgal/d. Potential problems associated with increases in pumpage and urban development are lowered water levels, contamination of the aquifers, and land subsidence. Long-term water-level declines in the Memphis Sand, the principal artesian aquifer of the area, range from less...

Streamflow and water-quality conditions, Wilsons Creek and James River, Springfield area, Missouri
Wayne R. Berkas
1982, Water-Resources Investigations Report 82-26
A network of water-quality-monitoring stations was established upstream and downstream from the Southwest Wastewater-Treatment Plant on Wilsons Creek to monitor the effects of sewage effluent on water quality. Data indicate that 82 percent of the time the flow in Wilsons Creek upstream from the wastewater-treatment plant is less than the...
