Model of the ground-water flow system of the Gordo and Eutaw aquifers in west-central Alabama
Richard Alfred Gardner
1981, Open-File Report 80-422
Hydrologic conditions for a two-aquifer system consisting of the Gordo and Eutaw aquifers of Cretaceous age in west-central Alabama were simulated using a three-dimensional finite difference digital model. The model was calibrated to observed heads in the aquifers using a least squares method for obtaining the values for hydraulic parameters...
Paleomagnetic study of the As Sarat volcanic field, southwestern Saudi Arabia
Karl S. Kellogg, Richard L. Reynolds
1981, Open-File Report 81-675
Four stratigraphic sections through alkali basalt flows of Oligocene-Miocene age (24 to 29 m.y.) in the As Sarat volcanic field, southwestern Saudi Arabia, were sampled for paleomagnetic study. Forty-two magnetically acceptable flows (139 samples) yield a mean direction of magnetization of D=-4.7°, 1=15.2° (α95=4.3°), which defines a paleomagnetic pole at...
Hydrologic data for North Creek, Trinity River basin, Texas, 1979
C.C. Kidwell
1981, Open-File Report 81-823
This report contains rainfall and runoff data collected during the 1979 water year for the 21.6-square mile area above the stream-gaging station North Creek near Jacksboro, Texas. A continuous water-stage recording gage was installed at one representative floodwater-retarding structure (site 28-A) on Oct. 5, 1972. The data are collected to...
Quality of water in Tibbee Creek and tributaries near West Point, Mississippi
Stephen J. Kalkhoff
1981, Open-File Report 81-406
An intensive water-quality study was conducted on Tibbee Creek and two of its tributaries, Town Creek and Catalpa Creek, on June 19-22, 1979. The data were collected during a period of low discharge and high air temperatures. The water in Tibbee Creek and Catalpa Creek was of much better quality...
Peak horizontal acceleration and velocity from strong motion records including records from the 1979 Imperial Valley, California, earthquake
William B. Joyner, David M. Boore, Ronald L. Porcella
1981, Open-File Report 81-365
We have taken advantage of the recent increase in strong-motion data at close distances to derive new attenuation relations for peak horizontal acceleration and velocity. Acceleration data from 183 recordings of 24 earthquakes and velocity data from 62 recordings of 10 earthquakes have been used. This new analysis uses a...
Map showing how the potentiometric surface of the Magothy Aquifer of September 1979 differed from the potentiometric surface of September 1977 in southern Maryland
Frederick K. Mack, J. C. Wheeler, Stephen E. Curtin
1981, Open-File Report 81-632
This map is based on the differences between two sets of water-level measurements made in 63 observation wells. One set was made in 1977, a relatively dry year, and the other set was made in 1979, a relatively wet year. The map shows that the potentiometric surface in 1979, in...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: June 1981
John B. Townshend, J.E. Papp, E.A. Sauter
1981, Open-File Report 81-300-F
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;...
Reconnaissance of the ground-water resources of Kings and Queens counties, New York
H. T. Buxton, Julian Soren, Alex Posner, P. K. Shernoff
1981, Open-File Report 81-1186
Western Long Island 's ground-water resources are being considered for redevelopment as a supplemental source of public water supply. The ground-water reservoir in Kings and Queens Counties had supplied an average of more than 120 million gallons per day for industrial and public water supply from 1904 to 1947. However,...
