Assess advanced understanding of trade-offs between green and gray stormwater infrastructure for flood mitigation and water quality in urban watersheds under projected climate scenarios. Candidates should analyze hydrologic and pollutant-removal performance, lifecycle costs, maintenance needs, co‑benefits (ecosystem services, public health, equity), and resilience using modeling outputs and scenario comparisons; tasks include interpreting model results, performing cost‑benefit or multi‑criteria analyses, and recommending climate‑robust integrated solutions with justification.
