Abstract : A computer simulation model for the MWA water supply system was developed, initially by a research team from Johns Hopkins University and later modified by the Corps of Engineers. The model, which was named the Potomac River Interactive Simulation Model (PRISM), was developed as a site-specific program for the major water supply utilities using the Potomac, Occoquan, and Patuxent sources. PRISM was subsequently used as the basic analytical tool for the long-range phase of the MWA Water Supply Study because it offered several attractive features: (1) the potential to analyze many water supply management schemes, (2) the ability to examine the effects on water supply of storage reallocation within Bloomington Lake, (3) the capability to investigate different regulation schemes within Bloomington Lake's existing authorization, (4) the potential to consider various flowby levels and the impacts on water supply surpluses or shortages, and (5) the ability to simulate long, historic droughts and observe the effects of different management schemes on stream flows, remaining reservoir storages, and water shortages. Because of PRISM's importance to both the Bloomington Lake Reformulation Study and the long-range phase of the overall MWA Water Supply Study, the purpose of Annex H-III is to fully describe the development and application of PRISM to the MWA water supply system.
