The Sea Data 651-4 data logger
David S. Hosom, Bradford Butman
1981, Open-File Report 81-111
This paper describes a digital data logger used as the primary controller and data collection device for the U.S. Geological Survey Sediment Monitoring Tripod Program. The tripods are deployed at sea in water depths up to 100 m for periods of 3 to 6 months. The system measures bottom current...
An assessment of streamflow, water quality, and the effects of constructing an impoundment on Bridge Creek at Augusta, Wisconsin
Leo B. House
1981, Open-File Report 81-1192
This study documents Streamflow, temperature, and water-quality conditions of Bridge Creek at Augusta, Wisconsin, and evaluates the potential effects of a proposed small impoundment on the creek. The effects are of concern to the Wisconsin Department of Natural Resources because the stream is a Class II trout stream. Average daily Streamflow,...
A method of estimating flood-frequency parameters for streams in Idaho
L.C. Kjelstrom, R. L. Moffatt
1981, Open-File Report 81-909
Skew coefficients for the log-Pearson type III distribution are generalized on the basis of some similarity of floods in the Snake River basin and other parts of Idaho. Generalized skew coefficients aid in shaping flood-frequency curves because skew coefficients computed from gaging stations having relatively short periods of peak flow...
A manual of modified analytical procedures for conventional rock analysis
Herbert Kirschenbaum
1981, Open-File Report 81-359
This manual was written to establish the most accurate analytical methodology for determining the major constituents in silicate rocks. This report describes modified classical procedures for determining the amount of SiO2, Al2O3, Fe2O3, FeO, CaO, MgO, H2O-, H2O+, TiO2, P2O5, MnO, CO2, and S in silicate rocks. In the determination...
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...
Water resources data for California, water year 1979; Volume 2: Pacific slope basins from Arroyo Grande to Oregon state line except Central Valley
California District of the Water Resources Division
1981, Water Data Report CA-79-2
Water-resources data for the 1979 water year for California consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; records of water levels in selected observation wells; and selected chemical analyses of ground water. Records for a few pertinent streamflow...
Flow model of Saginaw River near Saginaw, Michigan
David J. Holtschlag
1981, Open-File Report 81-1061
An unsteady-flow simulation model was applied to a 19.5-mile reach of Saginaw River. The model provides a method of determining instantaneous discharge for flows from -8,000 to 12,000 cubic feet per second. The currently used slope-rating method can be utilized to compute discharge only under steady and high-flow conditions. Unsteady...
Water resources data for Utah, water year 1980
Water Resources Division, U.S. Geological Survey
1981, Water Data Report UT-80-1
Water resources data for the 1980 water year for Utah consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality of ground water. This report contains discharge records for 294 gaging stations; stage and contents for...
Aquatic biology of the Redwood Creek and Mill Creek drainage basins, Redwood National Park, Humboldt and Del Norte counties, California
Rick T. Iwatsubo, R. C. Averett
1981, Open-File Report 81-143
A 2-year study of the aquatic biota in the Redwood Creek and Mill Creek drainage basins of Redwood National Park indicated that the aquatic productivity is low. Densities of coliform bacteria were low except in Prairie Creek, a tributary to Redwood Creek, where a State park, county fish hatchery, grazing...
Altitude and configuration of the water table in the High Plains aquifer in Kansas, 1980
Marilyn E. Pabst, Lloyd E. Stullken
1981, Open-File Report 81-1004
The High Plains aquifer in Kansas is part of a regional system that extends into Colorado, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming.  The aquifer in Kansas underlies an area of 31,000 square miles in the western and south-central part of the State.  This aquifer is a hydraulically...
Water resources data for California, water year 1980; Volume 3, Southern Central Valley basins and the Great Basin from Walker River to Truckee River
Water Resources Division, U.S. Geological Survey
1981, Water Data Report CA-80-3
Volume 3 of water resources data for the 1980 water year for California consists of records of stage, discharge, gage-height, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; water levels and water quality of wells. This report contains discharge records for 185 gaging stations;...
Depth estimation for ordinary high water of streams in the Mobile District of the U.S. Army Corps of Engineers, Alabama and adjacent states
Joe R. Harkins, Mark E. Green
1981, Open-File Report 81-481
Drainage areas for about 1,600 surface-water sites on streams and lakes in Florida are contained in this report. The sites are generally either U.S. Geological Survey gaging stations or the mouths of gaged streas. Each site is identified by latitude and longitude, by the general stream type, and by the...
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...
