Assess students' ability to analyze how conversion and intensification of agricultural land alter watershed hydrology (runoff, infiltration, baseflow, peak flow), increase nutrient (N, P) loading via surface runoff, subsurface flow, and tile drainage, and contribute to downstream eutrophication. Tasks include interpreting hydrographs and nutrient time-series, identifying transport pathways and legacy sources, applying simple nutrient-budget or conceptual models to predict algal bloom risk, and evaluating mitigation strategies (buffers, reduced fertilizer, wetlands).
