Simulation of ground-water flow in the lower sand unit of the Potomac-Raritan-Magothy aquifer system, Philadelphia, Pennsylvania

Ground-water flow in the lower sand unit of the Potomac-Raritan-Magothy aquifer system in Philadelphia was simulated with a two-dimensional finite- difference ground-water model. The modeled 133-square-mile area also included parts of Delaware County, Pennsylvania, and Camden and Gloucester Counties, New Jersey. The lower sand unit is Cretaceous in age and consists of well- sorted coarse sand and

Effects of urbanization on storm-runoff volume and peak discharge of Valley Creek, eastern Chester County, Pennsylvania

Peak discharge and runoff volume were simulated for 21 storms in the Valley Creek basin using the U.S. Geological Survey Distributed Routing Rainfall-Runoff Model (DR3M). Storm peak discharges ranged from 301 to 900 cubic feet per second. Rainfall was measured at three recording rain gages in the basin. Observed and simulated runoff volumes and peak discharges were compared for the upper 20.8 squa

Effects of flood controls proposed for West Branch Brandywine Creek, Chester County, Pennsylvania

Twenty-four-hour rainfall, distributed over time according to the U.S. Soil Conservation Service type II rainfall distribution, was used as input to calibrated rainfall-runoff models of three subbasins in the West Branch Brandywine Creek watershed. The effects of four proposed flood controls were evaluated by using these rainfalls to simulate discharge hydrographs with and without the flood contro

Water resources of Oley Township, Berks County, Pennsylvania

Oley Township covers an area of 24 square miles, about half of which is underlain by highly permeable carbonate rocks. Nondomestic wells in these rocks typically have yields of 200 gallons per minute, and some wells yield more than 1,000 gallons per minute. Ground-water yield for Oley Township is about 0.5 million gallons per day per square mile. Thus, about 12 million gallons per day could be pum

Sediment loads, discharges, and yields in the East Branch Mahoning Creek basin, Clearfield and Jefferson Counties, Pennsylvania, June 1979 through September 1981

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. During the study, 9,570 tons of sediment were transported from the Eas

Low-flow routing in the Lehigh and Delaware Rivers, Pennsylvania

Flow-routing studies were made to evaluate the response of the Lehigh and Delaware Rivers to low-flow augmentative releases from two reservoirs --Francis E. Walter Reservoir and Beltzville Lake--in the Lehigh River basin. Digital routing models that use diffusion-analogy methods to convolute flows with system-response functions were developed to simulate daily flows at selected sites. Model errors

Preimpoundment hydrologic conditions in the Swatara Creek (1981-84) and estimated postimpoundment water quality in and downstream from the planned Swatara State Park Reservoir, Lebanon and Schuylkill counties, Pennsylvania

The hydrology and water quality of Swatara Creek were studied by the U.S. Geological Survey in cooperation with the Pennsylvania Department of Environmental Resources, Bureau of State Parks, from July 1981 through September 1984. The purpose of the study was to determine the effects of anthracite-coal mining and other point and nonpoint sources on the water quality of a planned 10,500 acre-foot re

Geohydrology of the Furnace Creek basin and vicinity, Berks, Lancaster, and Lebanon counties, Pennsylvania

The Furnace Creek basin is an area of 8.95 square miles, about three- fourths of which is underlain by metamorphic rocks of low permeability. Reported yields for 14 wells in these rocks range from 1 to 60 gal/min (gallons per minute), with a median of 7.5 gal/min. The northern part of the study area consists of highly permeable carbonate rocks. Nondomestic wells in these rocks typically y

U.S. Geological Survey ground-water studies in Pennsylvania

In Pennsylvania, large water demands generally are met from surface-water sources; small water demands generally are met from ground-water sources. Ground-water sources supply 6 percent of the total water used in Pennsylvania. Of the ground water used in 1984,55 percent was for industry, 23 percent for public supply, 15 percent for rural domestic supplies, 5 percent for livestock, and 2 percent fo
