Hydrologic data for a study of pre-Illinoian glacial till in Linn County, Iowa, water year 1991
P.R. Bowman
1992, Open-File Report 92-500
Hydrologic data for a study of pre-lllinoian glacial till were collected during the 1991 water year at a site in Linn County, east-central Iowa. A hydrologic-data-collection network, consisting of a meteorological station, 22 observation wells, and a water-quality minimonitor, was installed at the site to investigate the hydraulic properties of...
Summary of hydrologic data for the San Gabriel River basin and Edwards Aquifer, Georgetown area, Texas, water year 1990
William E. Reeves, Larry F. Land
1992, Open-File Report 92-160
The Edwards aquifer is the principal source of freshwater for municipal, domestic, and industrial users in the Georgetown area.  Other sources of freshwater are Lake Georgetown and the streams draining the San Gabriel River basin.  Lake Georgetown, located on the North Fork San Gabriel River west of Georgetown, is a...
Selected meteorological data for an arid site near Beatty, Nye County, Nevada, calendar year 1987
James L. Wood, Jeffrey M. Fischer
1992, Open-File Report 92-59
Selected meteorological data were collected at a study site adjacent to a low-level radioactive-waste burial facility near Beatty, Nevada, for calendar year 1987. Data were collected in support of an ongoing study to estimate the potential for downward movement of radionuclides into the unsaturated sediments beneath waste-burial trenches at the...
Hydrologic data for the Big Spring basin, Clayton County, Iowa, water year 1990
Stephen J. Kalkhoff, R.L. Kuzniar, D. Kolpin, C.A. Harvey
1992, Open-File Report 92-67
Hydrologic data were collected in the Big Spring basin located in Clayton County, Iowa, during the 1990 water year. The data were collected by the U.S. Geological Survey in cooperation with the Iowa Department of Natural Resources, Geological Survey Bureau, to provide information on variation and movement of agricultural chemicals...
Records of wells in sandstone and alluvial aquifers and chemical data for water from selected wells in the Navajo aquifer in the vicinity of the greater Aneth Oil Field, San Juan County, Utah
Lawrence E. Spangler
1992, Open-File Report 92-124
This report contains hydrologic data for wells finished in sandstone and alluvial aquifers in southeastern San Juan County, Utah, and chemical data for water from selected wells in the Navajo aquifer. Temperature, specific conductance, pH, and discharge data from 1989-91 for water from selected wells in all aquifers are also...
Geohydrologic systems in Kansas; physical framework of the confining unit in the Western Interior Plains aquifer system
C. V. Hansen, R. J. Wolf, J. M. Spinazola
1992, Hydrologic Atlas 722-E
The purpose of this Hydrologic Investigations Atlas is to provide a description of the geohydrologic systems in Upper Cambrian through Lower Cretaceous rocks in Kansas. This investigation was made as part of the Central Midwest Regional Aquifer-System Analysis (CMRASA). The CMRASA is one of several major investigations by the U.S....
Techniques for estimating peak-flow frequency relations for North Dakota streams
Tara Williams-Sether
1992, Water-Resources Investigations Report 92-4020
This report presents techniques for estimating peak-flow frequency relations for North Dakota streams.  In addition, a generalized skew coefficient analysis was completed for North Dakota to test the validity of using the generalized skew coefficient map in Bulletin 17B of the Hydrology Subcommittee of the Interagency Advisory Committee on Water...
Water-supply potential of major streams and the upper Floridan Aquifer in the vicinity of Savannah, Georgia
Reggina Garza, R.E. Krause
1992, Open-File Report 92-629
Long-term pumping from the Upper Floridan aquifer in the Savannah, Georgia, area has lowered ground-water levels, resulting in increased salinity of ground water by seawater encroachment at Hilton Head Island, S.C., and by saltwater intrusion at Brunswick, Ga. Increased pumpage could cause further salinization of the ground-water resources. The Savannah...
Selected papers in the hydrologic sciences, 1988-92
Seymour Subitzky, editor(s)
1992, Water Supply Paper 2340
Selected Papers in the Hydrologic Sciences, a U.S. Geological Survey-managed journal-type publication in the Water-Supply Paper series, is aimed at meeting widespread public and professional needs for results of state-of-the-art broad-based hydrologic studies. The results of these studies are derived from integrated water-resource projects of the Federal research program, Federal-State...
Hydro-climatic data network (HCDN); a U.S. Geological Survey streamflow data set for the United States for the study of climate variations, 1874-1988
J. R. Slack, Jurate Maciunas Landwehr
1992, Open-File Report 92-129
Records of streamflow can provide an account of climatic variation over a hydrologic basin. The ability to do so is conditioned on the absence of confounding factors that diminish the climate signal. A national data set of streamflow records that are relatively free of confounding anthropogenic influences has been developed...
Ground-water-quality assessment of the central Oklahoma aquifer, Oklahoma: Hydrologic, water-quality, and quality-assurance data 1987-90
D. M. Ferree, S. C. Christenson, A. H. Rea, B. A. Mesander
1992, Open-File Report 92-641
This report presents data collected from 202 wells between June 1987 and September 1990 as part of the Central Oklahoma aquifer pilot study of the National Water-Quality Assessment Program. The report describes the sampling networks, the sampling procedures, and the results of the ground-water quality and quality-assurance sample analyses. The...
Simulation of water-table response to management alternatives, central part of the western San Joaquin Valley, California
K.R. Belitz, S.P. Phillips
1992, Water-Resources Investigations Report 91-4193
The occurrence of selenium in agricultural drainwater in the central pan of the western San Joaquin Valley, California, has focused concern on alternatives other than agricultural drains for managing shallow, poor-quality ground water. A transient, three-dimensional, finite-difference ground-water flow model was developed to assess the response of the water table...
