Watershed-Wide Stormwater Management Planning Issuesby Geoffrey A. Reese, Joint Planning Commission, Allentown, United States,
Abstract: Pennsylvania counties are responsible for basinwide stormwater management planning under the Stormwater Management Act of 1978. The predominant engineering technique employed within these plans to control peak flow rates is the Release Rate approach. The preferred modeling tool for watershed analysis and Release Rate determination is the Penn State Runoff Model (PSRM). Enhancements to PSRM specifically for this planning program allow for automation of Release Rate calculation. Specialized software development to link PSRM with detention pond routing software enables testing of PSRM-generated Release Rates. This analysis package enables the elimination of systematic Release Rate errors and provides for optimization of the runoff control strategy.
