Thoughts on the Implementation Plan for Urban Flood Prevention and Control under the Concept of Systematization:Case of a Central City in Shenzhen City
In order to solve the problem of urban waterlogging and improve the systematic management system,taking the waterlogging control of Longgang central city as an example,and proposed the implementation plan of"source control,pipe network upgrading,multielement storage and flood and waterlogging integration"based on the analysis of the causes of waterlogging.The paths,methods and applicable conditions of source runoff control,main pipelines optimization,blue-green space comprehensive utilization,river diversion were studied.At the same time,DHI MIKE model was used to evaluate the implementation effects,the results displayed,it achieved remarkable effects under comprehensive measures.Water depths of waterlogging points decreased to below 15 cm,with the highest decrease reaching 81％.The research can provide reference and guidance for following engineering construction.
