Abstract

With extreme urban growth in many countries, deleterious hydrologic, climate, and environmental problems associated with urban land development have become significantly serious due to increased peak flow, volume, and lag time of runoff; reduced underground water recharge; and degraded water quality [2,28,36,37,41]. With urban growth, forests, farms, and meadows are being transformed into houses, shopping centers, roadways, and parking lots, resulting in a much higher degree of imperviousness in such areas. Compared with soils covered by vegetation, the highly impervious nature of disturbed soils greatly reduces the infiltration capacity and the capability to recharge aquifers and maintain stream base flow and waterway health [5,9,24]. Stormwater management has become increasingly challenging with growth of urbanization and urban population across the world. Poor stormwater management causes many hydrologic, climate, and environmental problems [9,18,36], such as floods, increased erosion and sediment transport, water body contamination and eutrophication, and urban heat islands [2,6,40].
