Time-of-travel and dispersion studies, Lehigh River, Francis E. Walter Lake to Easton, Pennsylvania Time-of-travel and dispersion studies, Lehigh River, Francis E. Walter Lake to Easton, Pennsylvania

Results of time-of-travel and dispersion studies are presented for the 77.0 mile reach of the Lehigh River from Francis E. Walter Lake to Easton, Pennsylvania. Rhodamine WT dye was injected at several points for a variety of several common flow conditions and its downstream travel was monitored at a number of downstream points by means of a fluorometer. Time-of-travel data have been...

Effects of specific land uses on nonpoint sources of suspended sediment, nutrients, and herbicides, Pequea Creek basin, Pennsylvania, 1979-80 Effects of specific land uses on nonpoint sources of suspended sediment, nutrients, and herbicides, Pequea Creek basin, Pennsylvania, 1979-80

The Susquehanna River Basin Commission and the U.S. Environmental Protection Agency cooperated with the U.S. Geological Survey in a study to quantify nonpoint-source loadings from an agricultural area in Pennsylvania. Pequea Creek, a tributary to the Susquehanna River, drains a 154-square mile agricultural area in Lancaster County, Pennsylvania. Previous studies defined the Pequea Creek...

Hydrology of Area 1, eastern coal province, Pennsylvania [West Branch Susquehanna River, Sinnemahoning Creek, Upper Juniata River, Clearfield Creek] Hydrology of Area 1, eastern coal province, Pennsylvania [West Branch Susquehanna River, Sinnemahoning Creek, Upper Juniata River, Clearfield Creek]

Provisions of the Surface Mining Control and Reclamation Act of 1977 recognized a nationwide need for hydrologic information in mined and potentially mined areas. This report is designed to be useful to mine owners, operators, regulatory authorities, citizens groups, and others by presenting information on existing hydrologic conditions and by identifying additional sources of hydrologic

Effect of urbanization on the water resources of Warminster Township, Bucks County, Pennsylvania Effect of urbanization on the water resources of Warminster Township, Bucks County, Pennsylvania

Rapid suburban development occurred in Warminster Township and the surrounding area after World War II, resulting in a large population dependent on ground water. In 1980, approximately 2.7 billion gallons of ground water was pumped by public water suppliers and government facilities. Pumping wells can cause drawdown as far as 2,500 feet undip, downdip, or along strike even if the wells...

Johnstown-western Pennsylvania storms and floods of July 19-20, 1977 Johnstown-western Pennsylvania storms and floods of July 19-20, 1977

Widespread thunderstorms associated with two major squall lines, moved across Pennsylvania between the afternoon of July 19 and morning of July 20, 1977. The western part of outflow boundary produced by the second line became almost stationary in western Pennsylvania and resulted in 6 to 9 hours of nearly continuous thunderstorms. More than 6 inches of rain fell over a 400-square-mile...

Sedimentation in the East Branch Mahoning Creek basin, Clearfield and Jefferson Counties, Pennsylvania, June 1979 to June 1980 Sedimentation in the East Branch Mahoning Creek basin, Clearfield and Jefferson Counties, Pennsylvania, June 1979 to June 1980

Parts of the East Branch Mahoning Creek basin, a forested area of 29.6 square miles in west-central Pennsylvania, are disturbed by farming, surface mining, unpaved haul roads, eroding reclaimed areas, and logging. Streamflow was measured and water samples collected at a site upstream from the mouth from June 1979 to June 1980 during base flow and storm periods to evaluate sediment...

A stormwater management model for the West Branch Brandywine Creek, Chester County, Pennsylvania A stormwater management model for the West Branch Brandywine Creek, Chester County, Pennsylvania

Three subbasins in the West Branch Brandywine Creek watershed were modeled by the Dawby, Schaake, and Alley distributed routing rainfall- runoff model. The Honeybrook subbasin could not be calibrated because of nonrepresentative rainfall data. The Coatesville subbasin was calibrated, but not verified; the average standard error of estimate is 34 percent for peak discharge. The Modena...
