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.
