摘要
文中结合MIKE-21水动力学模型,对区域山洪灾害风险进行动态评估。结果表明:MIKE-21水动力学模型,可确定不同频率下各时段山洪灾害淹没范围。基于淹没范围,可定量评估不同淹没水深下洪水影响和损失的程度,实现区域山洪灾害的风险动态评估。
Combining with MIKE21 hydrodynamic model, the regional mountain torrent disaster risk is estimated dynamically. The results show that the MIKE21 hydrodynamic model could determine the inundation area in each period under different frequency. Based on the inundation area, the degree of flood impact and loss under different inundation depth are quantitatively evaluated, which could realize the risk dynamic evaluation of regional mountain torrent flood disaster.
