Description:

BMP processes into one model is highly desirable 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, 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 decision making considering 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 and each provides a unique contribution to the overall system. The ISMDSF will be capable of placing BMPs at multiple scales from a few city blocks to small and large watersheds. This paper provides an overview of this research effort and current details of the framework design. It also includes modeling concepts and process formulations for a stand-alone BMP model in the ISMDSF. There is currently a confusing array of options for analyzing hydrologic regimes and planning for BMPs. Integrating available.
