Assess students' ability to apply watershed hydrology and land‑use change analysis to design stormwater management solutions for a small urban catchment. Test skills in estimating runoff and peak discharge (e.g., rational method or CN/hydrograph concepts), evaluating how increased impervious area alters pollutant loads, selecting and sizing appropriate BMPs/LID (detention/retention, bioswales, permeable pavements), interpreting simple GIS/model outputs and hydrographs, performing trade‑off and cost‑benefit reasoning, and proposing monitoring metrics to demonstrate reduced peak flow and pollutant loads. Require quantitative calculations, design justification, and interpretation of modeled hydrographs/pollutographs.
