Abstract: As part of the COWAMP/208 Areawide Water Quality Management Program for the nine-county region that constitutes Southwestern Pennsylvania, an extensive analysis of the magnitude of the urban runoff problem in the study area was carried out. As the predictive tool for estimation of runoff quantity and quality, the U.S. Army Corps of Engineers' Storage Treatment Overflow Runoff Model (STORM) was employed. In order to calibrate the model to reflect local characteristics, a field sampling program was performed in several test basins in the study area. This paper describes the design, conduct, methodology, and results of the field program, and the use of this information in urban runoff flow and load projections.
