摘要：Using all national meteorological stations and regional automatic stations in the basin, data such as hourly precipitation, process precipitation and precipitation area forecast, digital elevation model, land use, soil type and field disaster investigation, etc. Based on the flood area model, the flood inundation simulation and effect test were carried out on the historical heavy rainfall period in the Datong River basin, which occurred at 20: 00 hours on July 5, 2013, at 20: 00 hours on July 5, 2017, and at 20: 00 o'clock in Datong River Basin. The simulation results show that the water level in the middle and upper reaches of the Datong River basin rises obviously, the water level in most areas exceeds 1 m, the water level in some tributaries is more than 3 m, and the water level in some areas of Zhuyang Township, Youhua Township and Qiaomu Township is more than 6 m. The results of disaster investigation show that the simulated values of flood flood area and flood area are in good agreement with the actual values, which indicates that the floodarea model has better simulation effect in Datong River basin. It can be used for risk assessment and early warning of torrential rain and flood disaster.
