Abstract: Assessment studies of N and P loads to water systems have developed from simple descriptions based on monitoring and sampling into the analysis of multiple scenarios using simulation models. In this study, water, sediment, and nutrient delivery to the stream flow at the Donga-Pont river catchment outlet (586km2) in the Republic of Benin, West Africa were simulated incorporating local management practices including detailed crop systems, fertilization and manure deposition, using the Soil and Water Assessment Tool (SWAT).
