[Assess understanding of the physical and biogeochemical mechanisms by which green infrastructure (e.g., bioswales, bioretention, permeable pavements, green roofs, urban trees, and constructed wetlands) reduces urban stormwater runoff and improves water quality; include infiltration, detention, evapotranspiration, filtration, sorption, microbial transformation, plant uptake, and sedimentation processes, relevant water-quality parameters (TSS, nutrients, metals), factors affecting performance (soil/media, vegetation, hydraulic loading, maintenance), and basic evaluation/monitoring approaches for professional practice.]
