This report presents preliminary results of ground water, stream sediment, and stream water studies in the Harrisburg quadrangle in Pennsylvania.

Supplementary data containing tabulated elemental concentrations in sediment, stream water, and ground water samples to accompany a report on hydrogeochemical and stream sediment reconnaissance.

From abstract: This data report presents preliminary results of ground water, stream sediment, and stream water reconnaissance in the National Topographic Map Series (NTMS) Williamsport 1° x 2° quadrangle.

From abstract: 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. The models used to route the flows of Cohocton and Chemung Rivers accounted for bank-storage discharge and streamflow depletion by well pumpage. In general, 17 years of concurrent streamflow data were available for model calibration and verification.

From abstract: An ARIMA (1, 0, 1) model is used to generate annual flow sequence at three sites in the Juniata River basin, Pennsylvania. The study was designed to analyze low-flow frequency characteristics of a basin. The model preserves the mean, variance, and cross-correlations of the observed station data.

From abstract: The objective of this project was to assess the magnitudes and types of nonpoint discharges that affect the water quality of Pequea Creek. The project included the determination of (1) the total discharge of suspended sediment, nitrogen, and phosphorus from the basin; (2) intermittent storm and base-flow discharges from six subbasin sites of varying size, geology, and land use; (3) the difference in magnitudes of the discharges during base-flow periods and storms; and (4) which variables most affect the transport of these constituents.

Abstract: 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 and 300 analyses of water from 196 wells and 43 springs. Also included are 103 trace-elements analyses. Monthly and annual means of ground-water levels for six observation wells are tabulated. Benthic invertebrate data from 136 stream sites are listed. Locations of data-collection sites are shown on 50 page-size reductions of 7.5-minute topographic quadrangle maps.

From introduction: The primary objective of this study, second in the series, is the development, calibration, and verification of flow-routing models for the Susquehanna River from Waverly, New York, to Sunbury, Pennsylvania. These models will permit SRBC to estimate the effects of water-resource developments upstream from Waverly at six locations on the Susquehanna River. They were also used to simulate for existing conditions at two ungaged sites.
