MIKE11模型在河道溃堤洪水模拟中的应用

基于MIKE11模型结构和原理,将MIKE11模型应用于洪泉片(豫)防洪保护区洪水风险图编制项目中,模拟干流河道的溃堤洪水过程,从各频率间结果、溃口与河道断面过流能力、水量平衡和实测洪水模拟四个方面,验证模拟结果的合理性。结果表明,MIKE11模型能较好地模拟河道溃堤洪水过程。

Application Research of Levee breach Flood Simulation Using MIKE11 Model

Based on the structure and principle of MIKE11 model, it was applied to the flood risk maps project for flood protection area of Hongquan region (Henan Province), and the levee breach flood process of river channel was simulated. Four aspects were contrastive analysis to verify the rationality of the simulation results, which included different frequency, discharge capacity of levee breach and river section, water balance and the simulation of measured flood process. The results show that the levee breach flood can be simulated effectively using MIKE11.
