The Watershed Assessment Model (WAM) was used to evaluate the flow, nitrogen, phosphorus, and biological oxygen demand (BOD) levels throughout the Hillsborough River Basin near Tampa, Florida. WAM was selected because of its comprehensive spatial analysis of land source areas and complex stream network routing techniques. WAM was able to simulate the control protocols for the structures on a major flood bypass system, a branched stream loop, and the instream water supply reservoir. Surface and groundwater water supply withdrawals and other point source discharges and withdrawals were well simulated by the model. WAM flow and constituent results matched well with observed data throughout the basin. WAM was also used to provide flow and nutrient/BOD loading information for a seven-year period (nine minute interval) to Water Quality Analysis Simulation Program (WASP) model. WASP is being used to simulate the DO and algal levels within TMDL-listed stream reaches to support EPA TMDL development.(Download PDF) (Export to EndNotes)
