Flow Routing in the Susquehanna River Basin: Part III -- Routing Reservoir Releases in the Tioga and Chemung Rivers System, Pennsylvania and New York (open access)

Flow Routing in the Susquehanna River Basin: Part III -- Routing Reservoir Releases in the Tioga and Chemung Rivers System, Pennsylvania and New York

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.

Regional Stochastic Generation of Streamflows using an Arima (1, 0, 1) Process and Disaggregation

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.

Technical Manual For Estimating Low-Flow Frequency Characteristics of Streams in the Susquehanna River Basin (open access)

Technical Manual For Estimating Low-Flow Frequency Characteristics of Streams in the Susquehanna River Basin

Abstract: This report presents procedures for estimating low-flow frequency characteristics for streams in the Susquehanna River basin. The techniques can be used at ungaged sites as well as sites where insufficient data are available to make a reliable estimate. Streams have been divided into two types major and minor. Major streams are the Susquehanna, West Branch Susquehanna, Juniata, and Chemung Rivers. Points on these streams with drainage areas of more than 2,000 square miles (5,180 kilometers) are included in this category. Points on these streams with drainage areas of less than 2,000 square miles fall into the minor stream category. Generally minor streams are herein defined as those draining less than 2,000 square miles (5,180 kilometers). Multiple-regression techniques have been used to develop relations for estimating the 1-, 3-, 7-, 30-, and 183-day duration low flows at recurrence intervals of 10, 20, 50 and 100 years for annual series data and the 1-, 3-, 7-, and 30-day duration low flows, at the same recurrence intervals, for six individual months, May through October, inclusive.
