The effects of highway construction on sediment discharge into Blockhouse Creek and Steam Valley Run, Pennsylvania

From October 1972 through September 1977, the effects of highway construction in the 38 square mile Blockhouse Creek basin were studied. Water discharge, suspended-sediment discharge, and stream-temperature data were collected at four stations in the basin. The 5-year period included 1 year before construction, 2 years during construction, and 2 years after construction. The effects of stream relo

Work plan for the Schuylkill River basin, Pennsylvania: Assessment of river quality as related to the distribution and transport of trace metals and organic substances

The U.S. Geological Survey is making a river-quality assessment of the Schuylkill River basin in Pennsylvania from October 1978 to March 1981. It is part of a continuing program designed to demonstrate the effectiveness of river-quality studies for basin planning and water-resource management. Study objectives include determining (1) presence of selected trace metals and organic substances in the

Effects of strip mining the abandoned deep Anna S Mine on the hydrology of Babb Creek, Tioga County, Pennsylvania

Daylighting (strip mining of coal seams previously deep mined) operations are being conducted on the Anna S Mine, that underlies about 850 acres that are drained by three major discharges. The Hunter Drift drains an underground area of about 400 acres, the Anna S 1 main entry, an area of 330 acres, and Mitchel 2 discharge an area of about 120 acres. As of August 1, 1979, about 55 acres (15%) had b

Development of a digital model of ground-water flow in deeply weathered crystalline rock, Chester County, Pennsylvania

The model developed in this study simulates .recharge to, flow through, and discharge from the water-table aquifer in the upper Pickering Creek basin, a 5.98-square-mile basin representative of most of Chester County, Pennsylvania. The two-dimensional finite-difference model of Trescott, Pinder, and Larson was used with slight modification. The way ground-water evapotranspiration varies with depth

Flow routing in the Susquehanna River Basin, Part II: Lowflow frequency characteristics of the Susquehanna River between Waverly, New York and Sunbury, Pennsylvania

Six flow-routing models were developed, calibrated, and verified for the Susquehanna River between Waverly, New York, and Sunbury , Pennsylvania. The models give the Susquehanna River Basin Commission tools to estimate effects of water-resource developments upstream from Waverly upon four gaged sites and two ungaged sites within the study reach. The models were used to simulate a 32-year record of

Flow routing in the Susquehanna River Basin: Part III -- Routing reservoir releases in the Tioga and Chemung rivers system, Pennsylvania, and New York, 1977

Channel-routing models were used to route hypothetical releases from reservoirs in the upper Tioga River basin, Pennsylvania. These releases were routed northward down the Tioga River to Lindley, Erwins, and Corning, New York: combined with flows routed down the Cohocton River from Campbell to Corning, New York; and then routed southeastward down the Chemung River from Corning to Chemung, New York

Nonpoint-source discharges in Pequea Creek Basin, Pennsylvania, 1977

A study of Pequea Creek included measurement of streamflow and collection of water and bottom-material samples during selected base-flow and storm periods from February to December 1977. Samples were analyzed for nitrogen and phosphorus species, suspended sediment, organic carbon, and pesticides. Daily mean constituent concentrations and discharges transported from the basin were computed for a ga

Selected water resources data, Clarion River and Redbank Creek basins, northwestern Pennsylvania: Part 2

This report presents selected basic data collected during a study of the water resources of the Clarion River and Redbank Creek basins in northwestern Pennsylvania. Hydrologic information including data on aquifers, water levels, and yields is presented for 1,304 wells. Records for 51 springs are also given. The report contains 83 chemical analyses of water samples collected from 30 stream sites a

Regional stochastic generation of streamflows using an ARIMA (1,0,1) process and disaggregation

An ARIMA (1,0,1) model was calibrated and used to generate long annual flow sequences at three sites in the Juniata River basin, Pennsylvania. The model preserves the mean, variance, and cross correlations of the observed station data. In addition, it has a desirable blend of both high and low frequency characteristics and therefore is capable of preserving the Hurst coefficient, h. The generated
