Analysis of"2024.8.10"rainstorm flood in Yangzhuang Reservoir of Tianjin City
摘要
Abstract
From August 9 to 10 of 2024,a short-term heavy rainstorm occurred in the Juhe River,and the flood peak flow of Yangzhuang Reservoir in Tianjin City reached the historical maximum of 1 100 m3/s.In this paper,based on the analysis of the characteristics of the rainstorm and flood characteristics,the hydrological and hydrodynamic models are constructed based on CNFF and IFMS/Urbans to simulate the rainstorm and flood process.The results show that:the return period of rainfall is 20～50 years,the return period of flood peak flow is 10～20 years,and the maximum discharge flow is 500 m3/s;The flood dispatching process effectively reduced the upstream flood peak by more than 50%,and there was no superposition of the maximum outflow and the flood peak,which gave full play to the flood control role of Yangzhuang Reservoir;River flood analysis and ground inundation analysis simulation are basically consistent with hydrological observation and field investigation.It is suggested that the reservoir should adopt the pre-discharge method in combination with the weather forecast during flood seasons,reduce the water level of the reservoir in advance,and control the discharge as far as possible at 300 m3/s and below.The research results can provide reference for flood forecasting and flood operation of Yangzhuang Reservoir.关键词
