Assess students' ability to apply watershed-scale hydrological and nutrient-transport modeling to evaluate how specified land-use change scenarios alter streamflow regimes and nutrient loads; include selection of model framework and inputs (climate, soils, DEM, land cover, management), design of calibration/validation and scenario simulations, interpretation of outputs (flow metrics, timing, annual/seasonal nutrient loads, source attribution), and execution of sensitivity/uncertainty analysis to support management or BMP recommendations given model limitations.
