Abstract
Taking Sanchuan River,Xinshui River and Sanggan River River,which are located in different hydrological subregions of Shanxi province,as an example,this paper analyzes the application of the dynamic critical rainfall warning index analysis method and the mountain flood disaster prediction model,which take into account the factors such as the previous rainfall,the accumulated rainfall,the rainfall intensity and the rainfall pattern distribution,etc.According to the prediction the prediction accuracy of the model is evaluated.The results show that the model has good applicability in typical hydrological regions of Shanxi province,and the qualified rate of prediction results of mountain flood disasters during the regular and validation periods of the three typical river basins is relatively high.According to the result of theoretical analysis,the model has universal applicability in other regions and river basins.关键词
