Increased population growth and, in many areas, uncontrolled urbanization, have led to increased imperviousness in cities across the world. This has resulted in an upsurge of urban flooding and the impairment of waterbodies due to increased stormwater flow rate, peak flow, and total volumes draining into streams, lakes, and estuaries. It has also resulted in larger pollutant loads that have impaired these water bodies. Traditional urban drainage systems, built with flooding in mind, drain stormwater rapidly into surface or subsurface conduits. Alternative sustainable urban drainage systems (SUDS) that integrate green stormwater infrastructure (GSI) practices can minimize flows from existing developments while controlling natural flows, thus reducing flooding and pollution and simultaneously increasing infiltration and groundwater recharge.
