【摘要】 以饮马河(石头口门水库坝址以下)为研究对象,采用MIKE 11、MIKE21以及MIKE FLOOD模型耦合进行了洪水演进数值模拟。通过对历史洪水进行模拟,以及对模型中参数的率定和验证,进而分析饮马河防洪保护区各溃口洪水演进及淹没情况。研究结果表明,研究区洪水分区空间合理,采用MIKE软件模拟精度高、效果好,成果可为防汛部门的风险评估、避险转移以及洪水风险图的绘制等防灾减灾工作提供重要依据和支撑。更多还原

【Abstract】 This paper takes Yinma River(below the dam site of Shitoukoumen Reservoir) as the research object. The numerical simulation of flood evolution is carried out by using MIKE 11, Mike 21 and Mike floor model coupling. Through the simulation of historical flood, as well as the calibration and verification of parameters in the model, further analysis of flood evolution and inundation in Yinma River flood protection area. The results show that the flood zoning space in the study area is reasonable, high simulation accuracy and good effects with Mike software. The results can provide important basis and support for the flood control department’s risk assessment, risk avoidance transfer and flood risk map drawing and other disaster prevention and mitigation work.更多还原
