Thinking of the construction of urban flood control and drainage system under extreme rainstorm events
In recent years,China has faced a surge in extreme rainfall events,leading to urban flooding and inundation.This has presented formidable challenges to emergency response and disaster relief efforts,resulting in substantial losses both in socio-economic terms and people's property.This paper delves into the causes of these extreme rainfall events,considering the perspectives of global warming and urbanization.Concurrently,it sheds light on prevailing issues within the urban flood and inundation prevention system,including construction setbacks,mounting contradictions,insufficient facility standards,and a disparity between construction and management.To effectively address extreme rainfall events,it is crucial to bolster the resilience of urban drainage systems,establish robust standards for flood control and drainage,rectify deficiencies in urban flood and inundation control projects,and enhance the operational efficiency of urban drainage facilities.The objective of this paper is to furnish a theoretical foundation for the development of urban flood and drainage systems in response to extreme rainfall events.
