基于MIKE FLOOD的深圳市大空港片区暴雨内涝模拟分析OA

Due to climate change and urbanization,extreme weather events such as heavy rainfall have increased,leading to the aggravation of urban waterlogging,which has a serious impact on urban traffic,residents'life,and infrastructure.Based on the MIKE FLOOD platform,this paper constructs a rainstorm waterlogging model by coupling the three models of MIKE 11,MIKE URBAN,and MIKE 21 to analyze the waterlogging problem in the Shenzhen Dakonggang area.It calibrates and verifies the parameters of the model using the measured water level and water depth data under the measured rainstorm conditions of Typhoon"Mangkhut"in 2018.Under different rainfall scenarios,the high-risk areas of waterlogging are mainly concentrated in the central region of the study area and near the river bank.In addition,according to the measured tide level of the"8·29"rainstorm,the simulation can be obtained:The total water accumulation area of the waterlogging point in the Dakonggang area with a depth of more than 15 cm is about 7.11 hm2.The research results can provide scientific technical support for the prevention and control of regional urban waterlogging.
