Water resources data, Washington, water year 1981: Vol. 1 - Western Washington
Water Resources Division, U.S. Geological Survey
1981, Water Data Report WA-81-1
Water-resources data for the 1981 water year for Washington consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground-water. This report, in two volumes, contains records for water discharge at 229 gaging...
Cooperative tectonic studies from seismic network in central Italy
L. Seeber, C.H. Scholz
1981, Open-File Report 81-92
The purpose of the subject contract work was to explore the possibility of tectonic research-work based on seismic data from a local network carried out as a cooperative effort between the Institute Nazionale di Geofisica (ING), Rome, and Columbia University (L-DGO), New York. This effort has been rather successful, and...
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...
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...
Geohydrology and numerical simulation of the alluvium and terrace aquifer along the Beaver-North Canadian River from the Panhandle to Canton Lake, northwestern Oklahoma
Robert E. Davis, Scott C. Christenson
1981, Open-File Report 81-483
A quantitative description of the hydrologic system in alluvium and terrace deposits along the Beaver-North Canadian River in northwestern Oklahoma is needed as an aid for planning and management of the aquifer. A two-dimensional finite-difference model was used to describe the aquifer and to predict the effects of future ground-water...
State-discharge relations at dams on the Illinois and Des Plaines rivers in Illinois
Dean M. Mades
1981, Open-File Report 81-1009
Stage-discharge relations were developed for the Brandon Road Dam on the Des Plaines River and the Dresden Island, Marseilles, Starved Rock, Peoria, and La Grange Dams on the Illinois River. A t Brandon Road Dam, streamflow is regulated by the operation of tainter gates and headgates. Tainter gates are operated...
Ground-water levels in Arkansas, spring 1981
Joe Edds
1981, Open-File Report 81-1114
This report contains records of water-level measurements from wells in Arkansas that comprise the statewide observation-well network maintained by the U.S. Geological Survey, in cooperation with the Arkansas Geological Commission. The observation-well network is designed to provide data for evaluation of the regional trend of water-level changes in each of...
Time of travel of solutes in the Vermilion River, Louisiana
Anthony J. Calandro
1981, Open-File Report 81-1065
Dye-tracer studies were made in November 1978 and in June 1979 to define streamflow patterns in the Vermilion River. For the November 1978 study the tracer was injected at two locations, Surrey Street in Lafayette and about 7 miles downstream at State Highway 3073; the discharge at Surrey Street at...
Surface-water quality, Twin Ponies watershed, Pottawattamie and Mills Counties, Iowa
Mark G. Detroy
1981, Open-File Report 81-679
Existing surface-water quality in the Twin Ponies watershed is significantly affected by runoff from agricultural lands that comprise most of the area. Runoff effects include the addition of phosphate, organic nitrogen, fecal bacteria, trace metals, pesticides and notably suspended sediment to streaMflow, because runoff commonly is a transport mechanism for...
Bibliography of reports resulting from U.S. Geological Survey scientific and technical cooperation with other countries, 1975 to June 1980
Wenonah E. Bergquist, Elizabeth J. Tinsley, Valerie S. Upton
1981, Open-File Report 81-896
This bibliography is a supplement to U.S. Geological Survey Bulletins 1426 (Bergquist, 1976) and 1263 (Heath and Tabacchi, 1968). The titles listed result from work undertaken by the U.S. Geological Survey in cooperation with national earth science agencies in other countries, partly through technical assistance projects under the auspices of...
