辽宁省浑河太子河中小流域水文特征相似性分析OA

In recent years,due to the shortage of hydrological data in the middle and small basins of Liaoning Province,the law of production and confluence is unclear,which makes it difficult to establish its forecast scheme.This paper takes 10 small and medium basins of Hunhe River and Taizihe River as the research object,and uses weighted Euclidean distance method to cluster similar basins from 7 hydrological factors including runoff characteristics,climate factors and underlying surface characteristics.The results show that the classification of similar basins is more reasonable,and the comprehensive rainfall and runoff relationship lines of similar basins can be established.The research results can provide scientific reference for the establishment of forecast schemes and parameter regionalization in areas without data.
