Sedimentation and water quality in the West Branch Shade River basin, Ohio, 1983-85
C. J. Oblinger Childress, R.L. Jones
1988, Water-Resources Investigations Report 87-4262
Loss of channel conveyance from deposition of sediment from abandoned surface mines in the West Branch Shade River basin has resulted in frequent flooding. In addition, water quality in the West Branch Shade River and some of its tributaries is typical of streams affected by acid mine drainage. About 938...

F. A. Packard, E.L. Skinner, L. A. Fuste
1988, Water-Resources Investigations Report 85-4274
Drainage from abandoned coal mines in western and central Washington has minimal environmental impact. Water quality characteristics that have the most significant environmental impact are suspended sediment and turbidity. Water quality data from 51 abandoned coal mines representing 11 major coal bearing areas indicate that less than 1% of the...

Description and hydrogeologic evaluation of nine hazardous-waste sites in Kansas, 1984-86
R. J. Hart, T.B. Spruill
1988, Water-Resources Investigations Report 88-4015
Wastes generated at nine hazardous-waste sites in Kansas were disposed in open pits, 55-gal drums, or large storage tanks. These disposal methods have the potential to contaminate groundwater beneath the sites, the soil on the sites, and nearby surface water bodies. Various activities on the nine sites included production of...
Sediment loads, discharges, and yields in the East Branch Mahoning Creek basin, Clearfield and Jefferson Counties, Pennsylvania, June 1979 through September 1981
C. A. Loper, K. L. Wetzel
1988, Water-Resources Investigations Report 85-4213
Rainfall, streamflow, and sediment discharge data were collected from the East Branch Mahoning Creek basin from June 1979 through September 1981 to evaluate sediment discharges from an area in which erosion and sediment controls were being used on surface mined areas. Sediment yields from the basin averaged 144 tons/sq mi/year....

Ground-water conditions in the Anza-Terwilliger area, with emphasis on the Cahuilla Indian Reservation, Riverside County, California, 1973-86
L. R. Woolfenden, D.J. Bright
1988, Water-Resources Investigations Report 88-4029
Demand for groundwater in the 96-sq mi Anza Terwilliger area of California has increased in recent years because of population growth and agricultural development.

Computer-program documentation of an interactive-accounting model to simulate streamflow, water quality, and water-supply operations in a river basin
A.W. Burns
1988, Water-Resources Investigations Report 88-4012
This report describes an interactive-accounting model used to simulate streamflow, chemical-constituent concentrations and loads, and water-supply operations in a river basin. The model uses regression equations to compute flow from incremental (internode) drainage areas. Conservative chemical constituents (typically dissolved solids) also are computed from regression equations. Both flow and water...
Review of mechanisms, methods, and theory for determining recharge to shallow aquifers in North Dakota
W.F. Horak
1988, Water-Resources Investigations Report 88-4122
Effective management of ground-water resources requires knowledge of all components of the water budget for the aquifer of interest. Efforts to simulate ground-water flow prior to development and the effects of proposed pumping in several of North Dakota's shallow glacial aquifers have been hindered by the lack of reliable estimates...
