| 摘 要： | 用部分溃坝的波流与堰流相交法模拟淦河流域溃口点的流量。以溃口点的流量、DEM为基础数据, 利用GIS的暴雨洪涝淹没模型, 对2010年7月14日淦河流域由强降水引发的溃口式洪水淹没过程进行模拟, 并利用实际灾情对模拟结果进行检验分析。模拟结果表明:随着洪水演进, 淦河流域的淹没面积不断地增大, 其中0.5~1 m水深段的淹没面积增长最快; 14日18时, 洪水到达任窝村, 20时淹没至马桥镇, 22时淹没至严洲村。灾情调查检验结果显示, 对于洪水到达时间和地点, 淹没模型模拟值与实况值较为吻合, 表明该模型在溃口式洪水淹没过程方面具有较好的模拟效果。

| Abstract: | A simplified method of wave current and weir flow intersection from the experiences of several dam-breaks was used to simulate the flood discharges from the Ganhe river during the dam-break on July 14, 2010.Flood routing of the dam-break was simulated by using GIS flood drowned model based on the flood discharges and DEM data.The simulation results was tested by using disaster result analysis.The result shows that the inundated areas of Ganhe river basin were constantly increasing with flood routing, especially for the 0.5~1 meters depth section of the inundated areas.The flood arrived in Renwo viliage at 18:00 on the 14th, then flooded to Maqiao and Yanzhou viliage at 20:00 and 22:00.According to the disaster investigation, in both the aspects of flooding time and flooding location, the simulation result of rainstorm inundation model agrees with the fact.This indicates that the model can better simulate the flood evolution of dam-breaks. |
