SEDPRO Modeling of BMP Effectiveness at Construction Sites

An overview of SEDPRO is given and used to illustrate impacts of changing land use on the environment during urban development. Its use is illustrated for selected watersheds within a rapidly developing area (Greenville County, SC, USA) Basic concepts and development of this innovative model are described to provide an understanding of the approach and limitations. Enhancements over the widely distributed SEDIMOT II and SEDIMOT III models include a graphical interface that features drag and drop placement of subwatersheds, best management practices (BMPs), and conveyances. This feature allows the user to place BMPs at points throughout the watershed and evaluate trapping efficiency of individual BMPs as well as the entire treatment train. Additional BMPs included are sand filters, bioswales, and engineered devices. It also can be used on any order watershed, not just the 3^rd order allowed in SEDIMOT. SEDPRO is used in the paper to illustrating the impact of alternative land uses and different types of construction.
