基于SkyHydrosat模型的山区洪水模拟复盘研究
A modelling assessment of flash floods based on SkyHydrosat model
摘要
Abstract
On 19th July,2024,one flash flood disaster occurred in the catchment of Jinqianhe River Basin in Shan-gluo City,Shanxi province,which let a highway bridge located closed to the downstream to be collapsed.This study proposes a modelling strategy by using the spatiotemporal distributed hydrological model developed by China Institute of Water Resources and hydropower Research(IWHR)to simulate the rainfall-runoff processes and to digitally explain the reason of the disaster.The Jinqianhe model created in the study showed high performance that both the error of flood peak and time meet the accuracy requests(flood peak error<0.1%,flood peak time error<1h).The distribution of rainfall-runoff coefficient of Jinqian sub-catchment is over 0.8;Shechun sub-catchment is in range from 0.2 to 0.4,and Matan sub-catchment is in range from 0.4 to 0.6.The collapsed highway bridge had suffered 2 flood peaks in 19th July(1,295 m3/s at 13:00pm and 1,431 m3/s at 21:00pm).The bridge failure is attributed to the superposition of 2 peaks.From this case study,the proposed strategy has been approved to be able to be applied for improving the understanding of flash flood disaster at mountainous catchments.关键词
