Description: This presentation will discuss the development of a SWAT+ model for the Black Hawk Lake watershed to simulate nutrient export under varying land use and BMP implementation trends. Using annual land use data and scenario analysis, the study forecasts long-term water quality impacts to support adaptive watershed management and policy planning.
