MIKE11模型在河道溃堤洪水模拟中的应用

Application Research of Levee-breach Flood Simulation Using MIKE11 Model

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。

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.
