考虑排水管网的海甸岛城市淹没影响数值模拟研究
Numerical simulation study on the impact of urban flooding on Haidian Island considering the drainage pipe network
摘要
Abstract
In order to investigate the effect of drainage system on urban compound inundation of Haidian Island under extreme weather conditions,a numerical model of storm surge flooding is established using the ADCIRC-SWMM coupled model.The simulation results show that the drainage system increases the connectivity between the internal system of Haidian Island and the ocean,which plays a positive role in flood prevention and drainage and reduces the urban inundation risk under normal conditions.When an extreme weather event occurs,especially the water level in the outer sea rises,the drainage inlet may be affected by the high tidal level,which leads to the reduction of the drainage efficiency.This suggests that the drainage system has a dual feature for urban flood control and drainage,which is conducive to flood control and drainage in normal conditions,but also increases the risk of urban inundation when extreme events occur.关键词
