Description:
To assist stormwater management professionals in planning for best management practices (BMPs) implementation, the U.S. Environmental Protection Agency (USEPA) is developing a decision support system for placement of BMPs at strategic locations in urban watersheds. This tool will help develop, evaluate, select, and place BMP options based on cost and effectiveness and is based on a system called the Integrated Stormwater Management Decision Support Framework (ISMDSF). The ISMDSF, a generic public domain framework, will provide a means for objective analysis of management alternatives among multiple interacting and competing factors. The desired outcome from the system application is a thorough, practical, and informative assessment considering the economic, environmental, and engineering factors. The design of the ISMDSF is completed and programming work has begun. The ISMDSF has seven key components: framework manager, ArcGIS interface, watershed model, BMP model, optimization model, post-processor, and Microsoft Access database. They are integrated under a common ArcGIS platform. The ISMDSF will support evaluation of BMP placement at multiple scales from a few city blocks to large watersheds. This paper provides an overview of this research effort and details of the framework design. It also includes modeling concepts and process formulations for the stand-alone BMP model in the ISMDSF. There is currently a confusing array of techniques typically used for analyzing hydrologic regimes and planning for BMPs. Integrating available BMP process simulation techniques into one model is highly desirable. The ISMDSF will provide a unified and consistent approach for evaluating the effects of BMP implementation
