Description:
The U.S. Environmental Protection Agency (USEPA) has funded the development of a decision support system for selection and placement of best management practices (BMPs) at strategic locations in urban watersheds. The primary objective of the system is to provide stormwater management professionals with a BMP assessment tool based on sound science and engineering that helps develop, evaluate, select and place BMP options based on cost and effectiveness. The system is called the Integrated Stormwater Management Decision Support Framework (ISMDSF) and is being designed through a systematic review of modeling needs, technical requirements, current and emerging data management technology, and available watershed and BMP models. The ISMDSF will be applied to a real urban watershed to evaluate its ability.
There are four major design aspects for the ISMDSF development. First, the system provides a robust computer platform for BMP selection, sizing, and placement in the context of several integrated watershed factors and influences. Second, it is applicable to mixed land use urban watersheds, and can perform watershed simulation based on watershed size, scale, anthropogenic, and natural characteristics. Third, it incorporates hydrologic/hydraulic and water quality modeling, integrating surface runoff and direct discharges to surface water bodies, based on relevant data collection. Finally, it will have the capability to objectively evaluate multiple solution alternatives based on cost and the desired water-quality objectives.
Programs that would benefit from the application of the ISMDSF include Municipal Separate Storm Sewer System (MS4) permits under the NPDES Stormwater Program (Phase I and II), Total Maximum Daily Load (TMDL) evaluations, and source-water protection. The ISMDSF will provide a means for objective analysis of management alternatives among multiple interacting and competing factors. The desired outcome from system application is a thorough, practical, and informative assessment considering the significant factors in urban watersheds. The systematic design process will ensure that the ISMDSF provides a platform with technical sophistication that is consistent with current and emerging technology.
