Assess students' ability to apply coupled surface–subsurface hydrological modeling to evaluate agricultural best management practices (BMPs) for reducing nitrate loads in mixed-use watersheds; scope includes model setup and coupling choices, parameterization, calibration/validation with streamflow and concentration data, design and comparison of BMP scenarios (e.g., buffer strips, cover crops, tile drain and fertilizer management), spatial-temporal analysis of nitrate transport and load reductions, sensitivity and uncertainty analysis, and translating model results into practical recommendations and monitoring strategies for stakeholders.
