SUDS: New solution for urban flooding

Abstract

Climate change causing extreme weather events across the world. The excising urban drainage system facing the great stress of managing heavy precipitation events and caused urban flooding. The specialists in the urban designing field are searching for more effective way of managing flooding events. Sustainable Urban Drainage System is kind of drainage system design which simulating nature rainwater managing practices. In this research, the SUDS is analyzed mainly from three aspects: Flood managing ability, economic benefits, and ecological benefits. This research reviews the existing SUDS examples and research basing on the SUDS designing strategies. Research has found that the SUDS is more than capable of managing stormwater but also can generate both monetary and indirect economic benefit. Furthermore, the nature feature of SUDS facilities can provide ecological benefits like providing habitats for animals, improving hydrological feature, and increase comfortability for residents. Thus, SUDS can be an ideal solution for the new urban drainage systems.
