Evaluation of the streamflow-data program in Pennsylvania Evaluation of the streamflow-data program in Pennsylvania

The stream-gaging program in Pennsylvania is subject to budgetary constraints in the next several years. Elimination of those gaging stations that have no current-purpose use and little utility in providing regional flow-characteristic information is the most effective way to reduce costs. The efficient design of a network of gaging stations for obtaining regional information requires...

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...

An evaluation of water-quality monitoring in the Brandywine Creek basin, Pennsylvania, 1973-78 An evaluation of water-quality monitoring in the Brandywine Creek basin, Pennsylvania, 1973-78

Data recorded from 1973 through 1978 by monitors on West Branch Brandywine Creek at Modena, East Branch Brandywine Creek below Downingtown, and Brandywine Creek at Chadds Ford were analyzed to evaluate the effectiveness of the monitors in describing water-quality conditions. The data show that the stream at Modena and below Downingtown had periods of low dissolved oxygen, and that the...

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...

Ground-water quality and data on wells and springs in Pennsylvania; Volume III, Delaware River basin Ground-water quality and data on wells and springs in Pennsylvania; Volume III, Delaware River basin

Volume III presents ground-water quality and physical data on about 1,250 wells and springs in the Delaware River Basin in Pennsylvania. Locations are shown on site-location maps derived from the hydrologic unit map. Codes showing the geologic age and aquifer are provided.

Sample mine-site permit application (hydrologic assessment) Sample mine-site permit application (hydrologic assessment)

Hydrologic data are presented that may be useful in the permitapplication procedure required under current Office of Surface Mining regulations. The material is presented in a format which may serve as a guide for subsequent permit applications. Data on the quality and quantity of surface water and ground water for the mine plan, adjacent, and general areas are presented. The data are...

Water resources of the Clarion River and Redbank Creek basins, northwestern Pennsylvania Water resources of the Clarion River and Redbank Creek basins, northwestern Pennsylvania

The Clarion River and Redbank Creek basin occupy 1,280 and 545 square miles, respectively, in northwatern Pennsylvania. The area is mostly in Clerion, Elk, and Jefferson Counties and is approximately 70 miles long and 30 miles wide. All drainage is to the Allegheny River. Sedimentary rocks of Late Devionian Early Mississippian, and Pennsylvanian age underlie the area. Rocks of Late...
