Test graduate students' ability to analyze how agricultural intensification and land-use change alter watershed hydrology and nitrate export under variable climate; tasks include interpreting hydrographs and nitrate time series, comparing model and scenario outputs (process-based and statistical), quantifying changes in runoff, baseflow, residence time and nutrient loads/concentrations, assessing the effects of precipitation extremes and drought, and recommending management or BMPs while addressing uncertainty and trade-offs.
