Selected water-quality and biological characteristics of streams in some forested basins of North Carolina, 1985-88
W.S. Caldwell
1992, Water-Resources Investigations Report 92-4129
Selected physical, chemical and biological components of streams draining undeveloped, forested basins in North Carolina were characterized on the basis of samples collected at nine sites on streams in basins that ranged in size from 0.67 to 11.2 sq mi. Water analysis included specific conductance, dissolved oxygen, water temperature, suspended...
Hydrochemistry of the surficial and intermediate aquifer systems in Florida
M. P. Berndt, B. G. Katz
1992, Water-Resources Investigations Report 91-4186
Hydrochemistry of the surficial and intermediate aquifer systems in Florida reflects the lithology and mineralogy of units within each aquifer and sources of water to each aquifer. The surficial aquifer system consists of sand, sandstone, clay, limestone, and shell units that are recharged primarily by precipitation. Calcium bicarbonate was the...
Mass-conserving method of characteristics for streamflow modeling
William G. Sikonia
1992, Water Supply Paper 2369
A robust numerical model is presented for the computation of unsteady streamflow on steep river slopes. The one-dimensional model uses the method of characteristics on a specified space-time grid to solve the Saint-Venant equations. An additional continuity equation requirement on each space-time element provides greatly improved conservation of mass over...
Evaluation of agricultural best-management practices in the Conestoga River headwaters, Pennsylvania; description and water quality of the Little Conestoga Creek headwaters prior to the implementation of nutrient management
D. K. Fishel, M. J. Brown, K. M. Kostelnik, M.A. Howse
1992, Water-Resources Investigations Report 90-4131
The headwaters of the Conestoga River are being studied to determine the effects of agricultural Best-Management Practices on surface-water and ground-water quality. As part of this study, a 5.82-square-mile area of the Little Conestoga Creek headwaters (Small Watershed) was monitored during 1984-86, prior to implementation of Best-Management Practices. This report...
Water resources data, West Virginia, water year 1991
S.M. Ward, B.C. Taylor, M.V. Mathes
1992, Water Data Report WV-91-1
Water-resources data for the 1991 water year for West Virginia consist of records of stage, discharge, and water quality of streams; contents of reservoirs; and water levels of observation wells. This report contains discharge records for 82 streamflow-gaging stations; stage only records for 7 gaging stations; annual maximum discharge at...
Selected meteorological data for an arid site near Beatty, Nye County, Nevada, calendar year 1989
J.L. Wood, Brian J. Andraski
1992, Open-File Report 92-484
Selected meteorological data were collected at a study site adjacent to a low-level radioactive-waste burial facility near Beatty, Nevada, for calendar year 1989. Data were collected in support of ongoing studies to estimate the potential for downward movement of radionuclides into the unsaturated sediments beneath waste-burial trenches at the facility....
Selected meteorological data for an arid site near Beatty, Nye County, Nevada, calendar year 1988
James L. Wood, Kevin J. Hill, Brian J. Andraski
1992, Open-File Report 92-61
Selected meteorological data were collected at a study site adjacent to a low-level radioactive-waste burial facility near Beatty/ Nevada, for calendar year 1988. Data were collected in support of ongoing studies to estimate the potential for downward movement of radionuclides into the unsaturated sediments beneath waste-burial trenches at the facility....
