Statistical analyses of flood frequency, low-flow frequency, and flow duration of streams in the Philadelphia Area, Pennsylvania
Andrew Voytik
1986, Water-Resources Investigations Report 85-4008
Flood frequency, low-flow frequency, and flow-duration characteristics were computed for 26 stream-gaging stations in and near Philadelphia. Data were obtained from 21 continuous-recording stations and five stations that were initially continuous-recording stations, but which were subsequently converted to crest-stage stations. The annual peak flows were fitted to the three-parameter log-Pearson...
Quality of ground water in southeastern and south-central Washington, 1982
G. L. Turney
1986, Water-Resources Investigations Report 84-4262
In 1982 groundwater was sampled at over 100 sites in the southeastern-south central region of Washington and analyzed for pH, specific conductance, and concentrations of fecal-coliform bacteria, major dissolved irons, and dissolved iron, manganese, and nitrate. Twenty percent of the samples were analyzed for concentrations of dissolved aluminum, arsenic, barium,...
Plan of study for the Regional Aquifer-System Analysis, Columbia Plateau, Washington, northern Oregon, and northwestern Idaho
J. J. Vaccaro
1986, Water-Resources Investigations Report 85-4151
The U.S. Geological Survey began a 4-year study of the regional aquifer system underlying the Columbia Plateau, in central and eastern Washington, northern Oregon, and northwestern Idaho in October 1983, as part of the Regional Aquifer System Analysis program. The study will describe the geohydrology, geochemistry, and quality of water...
Geohydrology of the southwest alluvial basins regional aquifer- systems analysis, parts of Colorado, New Mexico, and Texas
D. W. Wilkins
1986, Water-Resources Investigations Report 84-4224
The Southwest Alluvial Basins study is part of the National Regional Aquifer-Systems Analysis program. Twenty-two structural basins extend from the San Luis Basin in southern Colorado to the Presidio Basin in western Texas. Closed surface-water basins west of the Guadalupe Mountains and east of the Peloncillo Mountains are included in...
History of ground-water pumpage and water-level decline in the Black Creek and upper Cape Fear aquifers of the central coastal plain of North Carolina
M.D. Winner, W.L. Lyke
1986, Water-Resources Investigations Report 86-4168
Historical ground-water withdrawals and a general water-level decline in the Black Creek and upper Cape Fear aquifers of the central Coastal Plain of North Carolina are documented. Total municipal and industrial pumpage from these aquifers has increased from approximately 120,000 gal/day (gpd) in 1910 to >21 million gpd in 1980....
Ground-water data for the Hanna and Carbon basins, south-central Wyoming, through 1980
P. B. Daddow
1986, Open-File Report 85-628
Groundwater resources in the Hanna and Carbon Basins of Wyoming were assessed in a study from 1974 through 1980 because of the development of coal mining in the area. Data collected from 105 wells during that study, including well-completion records, lithologic logs, and water levels, are presented. The data are...
Water resources data, New Mexico, water year 1985
Louis P. Denis, Linda V. Beal, Harriet R. Allen
1986, Water Data Report NM-85-1
Water resources data for the 1985 water year for New Mexico consist of records of discharge and water quality of streams; stage, contents and water quality of lakes and reservoirs; and water levels and water quality in wells and springs. This report contains discharge records for 168 gaging stations; stage...
