Urban Stormwater and Runoff Management
Urban areas have large areas of impervious surfaces, which cause water to run off during storms (rather than retaining water or allowing it to infiltrate into the ground). This creates issues with stormwater flooding and, in cities with combined sewer systems, can also lead to sewer overflows following rainfall. Nature-based solutions (NBS) strategies for urban stormwater and runoff management such as rain gardens, stormwater parks, permeable pavement, and bioswales are intended to reduce these issues by promoting water retention, infiltration, and evapotranspiration instead of runoff (Palermo et al. 2023).
