为加强宁晋泊和大陆泽蓄滞洪区的安全建设规划,利用MIKE FLOOD软件包建立宁晋泊和大陆泽蓄滞洪区的一、二维耦合模型,采用“96.8”历史洪水淹没资料进行模型验证,对大陆泽任县环水村不同时刻的模拟水位和实测水位进行了对比,模拟结果与实际基本吻合。利用该模型模拟了蓄滞洪区50年一遇的洪水淹没过程,得到了洪水淹没范围、水深、历时等洪水淹没特征信息,并以最大淹没水深单指标来进行洪水风险分区,绘制洪水风险图,为蓄滞洪区的安全建设规划提供了重要依据。
In order to strengthen the construction plan of safety in Ningjinba and Dazuze flood detention areas, a one-dimensional and two-dimensional coupled model of detention basin of Ningjinpo and Dazuze was established by using MIKE FLOOD software package, and the data of “96.8” historical flood inundation The model verification is made to compare the simulated water level and the measured water level at different times of the Huan Shui Village in Zeren County of the Mainland. The simulation results are in good agreement with the actual situation. This model is used to simulate flood inundation process in a 50-year flood season and flood inundation area, water depth and duration are obtained, flood risk is partitioned by single maximum inundated water depth index, flood risk map is drawn, It provides an important basis for the safety planning of flood detention areas.
