基于MIKE21模型的盛庄洼蓄滞洪区洪水淹没分析

Flood submergence analysis of Shengzhuangwa flood storage and detention basin based on MIKE21 model

本文采用MIKE21方法模拟计算不同工况下盛庄洼蓄滞洪区洪水淹没情况,同时采用蓄滞洪区水位-容积曲线对蓄滞洪区淹没情况进行对比分析,从淹没水深、洪水到达时间和淹没历时3个方面对比计算成果。结果显示:上述两种方法得到蓄滞洪区内淹没成果基本一致,MIKE21模型计算成果可为蓄滞洪区防汛调度预案的制定提供技术支撑。

In this paper, MIKE21 method is used to simulate and calculate the flood inundation situation in Shengzhuangwa flood storage and detention area under different working conditions. At the same time, the flood inundation situation in the flood storage and detention area is compared and analyzed by using the water level-volume curve of the flood storage and detention area, and the calculation results are compared from three aspects of inundation depth, flood arrival time and inundation duration. The results show that the flood control results obtained by the above two methods are basically the same, and the calculation results of MIKE21 model can provide technical support for the formulation of flood control and dispatching plans for flood storage and detention areas.
