Waterlogging Prevention and Control Planning Based on the Concept of Sponge City - A Case Study of Kirin Science and Technology City

Abstract

With the accelerated development of urbanisation, the problem of waterlogging is increasingly becoming a serious challenge for cities. In order to effectively deal with the risk of waterlogging, this study proposes a set of waterlogging prevention and control planning based on the concept of sponge city construction. It focuses on giving full play to the water reduction effect of Low Impact Development (LID) facilities through the integrated application of ecological emission reduction systems and drainage and risk removal technologies to reduce rainwater runoff and improve the city’s flooding resilience. The method is applied to Kirin Science and Technology City as an example, and the results show that the total annual runoff control rate, the water surface rate, and the water surface storage capacity of this area are all significantly improved, which can provide a reference for deepening the scientific understanding of the mechanism of urban rainfall and flood formation and adopting effective management means.
