Sensitivity of water resources in the Delaware River basin to climate variability and change Sensitivity of water resources in the Delaware River basin to climate variability and change

Because of the greenhouse effect, projected increases in atmospheric carbon dioxide levels might cause global warming, which in turn could result in changes in precipitation patterns and evapotranspiration and in increases in sea level. This report describes the greenhouse effect; discusses the problems and uncertainties associated with the detection, prediction, and effects of climate...

Determination of traveltime in the Delaware River, Hancock, New York, to the Delaware Water Gap by use of a conservative dye tracer Determination of traveltime in the Delaware River, Hancock, New York, to the Delaware Water Gap by use of a conservative dye tracer

Traveltime of a soluble substance was determined for a 120-mile reach of the Delaware River from the confluence of the East Branch Delaware River and the West Branch Delaware River at Hancock, N.Y. to the Delaware Water Gap. Dye studies were conducted at the 85-95 percent and the 25-30 percent flow durations. Discharges ranged from 500-1,740 cubic feet per second during the 85-95 percent...

Calibration of a streamflow-routing model for the Delaware River and its principal tributaries in New York, New Jersey, and Pennsylvania Calibration of a streamflow-routing model for the Delaware River and its principal tributaries in New York, New Jersey, and Pennsylvania

The flow-routing module of the Hydrologic Simulation Program-Fortran watershed model was calibrated for 31 reaches on the Delaware River and 5 of it principal tributaries. These calibrations primarily involved the development of discharge-storage volume relations for the defined reaches. Daily discharge records for stream-gaging stations located at the upstream ends of the study reaches...

Altitude and configuration of the potentiometric surface, May and June 1993, and change in water level 1983-93, in the carbonate rocks in part of East Whiteland and Charlestown Townships, Chester County, Pennsylvania Altitude and configuration of the potentiometric surface, May and June 1993, and change in water level 1983-93, in the carbonate rocks in part of East Whiteland and Charlestown Townships, Chester County, Pennsylvania

A map showing ground-water levels in the carbonate rocks of northern Chester County, Pa., was constructed on the basis of water levels in 51 wells measured in May and June 1993. The area studied underlies parts of East Whiteland and Charlestown Townships. Water-level altitudes range from about 413 feet above sea level on Phoenixville Pike to 130 feet above sea level along Route 29.

Water resources data, Pennsylvania, water year 1992. Volume 2. Susquehanna and Potomac River basins Water resources data, Pennsylvania, water year 1992. Volume 2. Susquehanna and Potomac River basins

Water resources data for the 1992 water year for Pennsylvania consist of records of discharge and water quality of streams; contents and elevations of lakes and reservoirs; and water levels and water quality of ground-water wells. This report, Volume 2, includes records from the Susquehanna and Potomac River basins. Specifically, it contains (1) discharge records for 85 continuous-record

Concentration history during pumping from a leaky aquifer with stratified initial concentration Concentration history during pumping from a leaky aquifer with stratified initial concentration

Analytical and numerical solutions are employed to examine the concentration history of a dissolved substance in water pumped from a leaky aquifer. Many aquifer systems are characterized by stratification, for example, a sandy layer overlain by a clay layer. To obtain information about separate hydrogeologic units, aquifer pumping tests are often conducted with a well penetrating only...

Water resources and the hydrologic effects of coal mining in Washington County, Pennsylvania Water resources and the hydrologic effects of coal mining in Washington County, Pennsylvania

Washington County occupies an area of 864 square miles in southwestern Pennsylvania and lies within the Pittsburgh Plateaus Section of the Appalachian Plateaus physiographic province. About 69 percent of the county population is served by public water-supply systems, and the Monongahela River is the source for 78 percent of the public-supply systems. The remaining 31 percent of the...

The mapped area in underlain by layered sedimentary rocks chiefly consisting of shale, mudstone, siltstone, and argillite and by a diabase sheet thtat has intruded the sedimentary rocks. The sedimentary rocks adjacent to the diabase are thermally altered to hornfels. Water levels in shallow wells completed in the diabase indicate the presence of an upper, shallow aquifer system.
