Assess students' ability to apply watershed-scale hydrologic and nutrient-transport models to design and evaluate best management practices (BMPs) that reduce nitrate loading to eutrophic estuaries; tasks include model selection and setup, spatially distributed input development, parameterization and calibration of hydrology and nitrogen processes, scenario analysis of BMP placement and timing, interpretation of load reductions and uncertainty, and evaluation of cost-effectiveness and compliance with estuarine water-quality targets at appropriate temporal and spatial scales.
