Field data describing the movement and storage of sediment in the East Fork River, Wyoming; Part III, river hydraulics and sediment transport, 1980
W. W. Emmett, R. M. Myrick, R.H. Meade
1982, Open-File Report 82-359
Frequent measurements of river stage, water discharge, sediment-transport rate and particle-size gradation, and river slope were made at 44 cross sections along a 1.83-kilometer reach of East Fork River, Wyoming, during the spring 1980 snowmelt runoff. Data are tabulated and explanatory text facilitates its use for description of river hydraulics...
Near-station terrain corrections for gravity data by a surface-integral technique
M. E. Gettings
1982, Open-File Report 82-1045
A new method of computing gravity terrain corrections by use of a digitizer and digital computer can result in substantial savings in the time and manual labor required to perform such corrections by conventional manual ring-chart techniques. The method is typically applied to estimate terrain effects for topography near the...
Background hydrologic information in potential lignite mining areas in Mississippi, August 1981
J. K. Arthur
1982, Open-File Report 82-326
The U.S. Geological Survey in cooperation with the Mississippi Bureau of Geology is conducting a hydrologic data-collection program in potential lignite-producing areas in Mississippi. During the period August 24-31, 1981, hydrologic data consisting of channel characteristics and stream discharge were collected at 18 sites, and water and channel bottom material...
Annual Nutrient Loadings, Primary Productivity, and Trophic State of Lake Koocanusa, Montana and British Columbia, 1972-80
Paul F. Woods
1982, Professional Paper 1283
Limnological data collected at Lake Koocanusa were used to investigate the relationship of nutrient loadings, primary productivity, and trophic state of the reservoir during 1972-80. The reservoir, on the Kootenai River, was impounded by Libby Dam on March 21, 1972. Manipulation of the 7.16-cubic-kilometer reservoir for flood control, its primary...
Aquifer data from four wells in the Mendenhall Valley near Juneau, Alaska
G. O. Balding, L.L. Dearborn
1982, Open-File Report 82-271
This report summarizes data collected during drilling and testing of four wells in Mendenhall Valley, an area being developed as a suburb of Juneau, Alaska. Previous studies indicated that the glacial deposits on the east side of the valley had the potential for producing the large quantities of water needed...
Drainage divides, Massachusetts; Blackstone and Thames River basins
Bruce E. Krejmas, S. William Wandle
1982, Open-File Report 82-631
Drainage boundaries for selected subbasins of the Blackstone and Thames River basins in eastern Hampden, eastern Hampshire, western Norfolk, southern Middlesex, and southern Worcester Counties, Massachusetts, are delineated on 12 topographic quadrangle maps at a scale of 1:24,000. Drainage basins are shown for all U.S. Geological Survey data-collection sites and...
Hydrologic data-verification management program plan
C.W. Alexander
1982, Open-File Report 82-374
Data verification refers to the performance of quality control on hydrologic data that have been retrieved from the field and are being prepared for dissemination to water-data users. Water-data users now have access to computerized data files containing unpublished, unverified hydrologic data. Therefore, it is necessary to develop techniques and...
Selected hydrologic data for northern Utah Valley, Utah, 1935-82
Cynthia L. Appel, David W. Clark, Paul E. Fairbanks
1982, Open-File Report 82-1023
This report contains hydrologic data collected in northern Utah Valley from 1935 to 1982. Northern Utah Valley is approximately the northern half of an alluvial-filled basin partly occupied by Utah Lake in north-central Utah. The report area is bounded by the Wasatch Range on the east, the Lake Mountains on...
Quality-of-water data and statistical summary for selected coal-mined strip pits in Crawford and Cherokee counties, southeastern Kansas
Larry M. Pope, A.M. Diaz
1982, Open-File Report 82-1021
Quality-of-water data, collected October 21-23, 1980, and a statistical summary are presented for 42 coal-mined strip pits in Crawford and Cherokee Counties, Southeastern Kansas. The statistical summary includes minimum and maximum observed values , mean, and standard deviation. Simple linear regression equations relating specific conductance, dissolved solids, and acidity to...
Geologic and well-construction data for the H-9 borehole complex near the proposed Waste Isolation Pilot Plant site, southeastern New Mexico
S.L. Drellack, J.G. Wells
1982, Water-Resources Investigations Report 82-4111
The H-9 complex, a group of three closely spaced boreholes, is located 5.5 miles south of the proposed Waste Isolation Pilot Plant (WIPP) site in east-central Eddy County, New Mexico. The holes were drilled during July, August, and September 1979 to obtain geologic and hydrologic data to better define the...
Preliminary evaluation of the ground-water-flow system in the Twin Cities Metropolitan area, Minnesota
John H. Guswa, Donald I. Siegel, Daniel C. Gillies
1982, Water-Resources Investigations Report 82-44
A preliminary quasi-three-dimensional finite-difference ground-water-flow model of the seven-county Twin Cities Metropolitan area was constructed and used to evaluate parameter sensitivity and adequacy of available data. Fourteen geologic units that underlie the study area were grouped into nine hydr,bgeologic units and were incorporated into a five-layer model. The layers in...
Water-quality assessment of the Merced River, California
Stephen K. Sorenson
1982, Open-File Report 82-450
The Merced River and its major tributaries have been subject of water-quality and water-quantity studies by local, State, and Federal agencies since before 1900. Data have been compiled and analyzed, and even though water-quality problems exist in the basin, the water generally is of good quality for most of the...
Temperatures and interval geothermal-gradient determinations from wells in National Petroleum Reserve in Alaska
D.C. Blanchard, I.L. Tailleur
1982, Open-File Report 82-391
Temperature and related records from 28 wells in the National Petroleum Reserve in Alaska (NPRA) although somewhat constrained from accuracy by data gathering methods, extrapolate to undisturbed formation temperatures at specific depths below permafrost, and lead to calculated geothermal gradients between these depths. Tabulation of the results show that extrapolated...
