Assess students' ability to apply watershed-scale nutrient modeling to design, run, and interpret scenarios evaluating how agricultural best management practices (BMPs) change riverine nitrogen and phosphorus export. Scope: model selection and setup, representation of BMPs (e.g., cover crops, riparian buffers, fertilizer timing, tile drainage), calibration and uncertainty analysis, seasonal and load-based comparisons, and translating results into management recommendations and trade-offs.
