Simulation of unsteady flow in the Roanoke River from near Oak City to Williamston, North Carolina
A one-dimensional, unsteady-flow model was calibrated, validated, and applied to a 30.4-mile reach of the Roanoke River between State Highway 42-11 bridge near Oak City (river mile 67.0) and U.S. Highway 17-13 bridge (river mile 36.6) at Williamston, North Carolina. The model was calibrated and validated for water levels ranging from 5.62 to 16.44 feet at river mile 67.0, and for flows ranging fro

Hydrogeologic data collected from a crude-oil spill site near Bemidji, Minnesota, 1983-91
The U.S. Geological Survey began a research project at the site of a crude oil spill near Bemidji, Minnesota in 1983. The project is part of the U.S. Geological Survey's Toxic Substances Hydrology Program. The objectives of research at this site are to obtain an understanding of the mobilization, transport, and fate of petroleum derivatives in the shallow subsurface and to use this understanding t

Surface- and ground-water quality data at selected landfill sites in Mecklenburg County, North Carolina, 1979-92
The U.S. Geological Survey initiated an urban water-quality study in 1979 in cooperation with the City of Charlotte and Mecklenburg County, North Carolina. As part of this study, a water-quality monitoring network was established at selected landfill sites in Mecklenburg County. Water-quality samples were collected at 27 surface-water sites and 97 ground-water sites at 5 landfills from 1979-92. Sa

Geochemistry and migration of contaminants at the Weldon Spring chemical plant site, St. Charles County, Missouri, 1989-91
The geochemistry of the shallow aquifer and geochemical controls on the migration of uranium and other constituents from raffinate pits were determined at the Weldon Spring chemical plant site. Surface-water samples from the raffinate pits con- tained large concentrations of calcium, magnesium, sodium, potassium, sulfate, nitrite, lithium, moly- bdenum, strontium, vanadium, and uranium. Analyses o

Documentation of model input and output values for simulation of regional ground-water flow, carbonate-rock province, Nevada, Utah, and adjacent states
Documentation of model input values and sample output used during a conceptual evaluation of the regional ground-water flow in the carbonate-rock province of the Great Basin, Nevada, Utah, and adjacent states, was revised from previously published Open-File Report 91-479. The documentation, consisting of a listing of input values and sample output, is contained on a 5-1/4-inch diskette in files pr

Physical-property, water-quality, plankton, and bottom-material data for Devils Lake and East Devils Lake, North Dakota, September 1988 through October 1990
Physical-properties were measured and water-quality, plankton, and bottom-material samples were collected at 10 sites in Devils Lake and East Devils Lake during September 1988 through October 1990 to study water-quality variability and water-quality and plankton relations in Devils Lake and East Devils Lake. Physical properties measured include specific conductance, pH, water temperature, dissolve

Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory-Determination of chromium in water by graphite furnace atomic absorption spectrophotometry
Graphite furnace atomic absorption spectrophotometry is a sensitive, precise, and accurate method for the determination of chromium in natural water samples. The detection limit for this analytical method is 0.4 microg/L with a working linear limit of 25.0 microg/L. The precision at the detection limit ranges from 20 to 57 percent relative standard deviation (RSD) with an improvement to 4.6 percen

Public-supply water use in Florida, 1990
In 1990, public supply withdrawals represented nearly 26 percent of the total freshwater withdrawn in Florida. Total water withdrawn for public supply in Florida during 1990 averaged 1,925 million gal/day. Public suppliers served 11.23 million residents, in 1990. Groundwater was the source for more than 88 percent (1,699 million gal/day) of public-supply withdrawals and was used by more than 10.0

Water-resources investigations in Wisconsin, 1993
PROBLEM: Surface-water information is needed for surveillance, planning, design, hazard warning, operation, and management in water-related fields such as water supply, hydroelectric power, flood control, irrigation, bridge and culvert design, wildlife management, pollution abatement, flood-plain management, and water-resources development. An appropriate data base is necessary to provide this inf

Ground-water quality at the Management Systems Evaluation Area near Princeton, Minnesota, 1991-92
The northern cornbelt sand-plains Management Systems Evaluation Area (MSEA) program is a multiagency, multistate initiative to evaluate the effects of modified and prevailing farming systems on water quality in a sand-plain area in Minnesota and at satellite areas in North and South Dakota, and Wisconsin. The primary objective of Minnesota MSEA is to evaluate the effects of ridge-tillage practices
