Eleven watershed scale hydrologic and nonpoint-source pollution models were reviewed, and the mathematical bases of different components were identified and compiled. Among the fully developed hydrologic and nonpoint source pollution models having all the three major components: hydrology, sediment, and chemical, SWAT was found to be a promising model for long-term continuous simulations in predominantly agricultural watersheds and HSPF for mixed agricultural and urban watersheds. DWSM was found to be a promising storm event simulation model for agricultural watersheds. These models were investigated further. Many applications of these models, found and available in the literature, were reviewed and compiled. Brief descriptions of these review studies are presented here, details are presented in other cited references.(Download PDF) (Export to EndNotes)
