五强溪流域相似性研究及参数移植分析
Similarity and Parameter Transplantation Analysis of Wuqiangxi Basin
摘要
Abstract
Under the guidance of the Predictions in Ungauged Basins(PUB)plan,the study of watershed similarity has been further developed.In order to explore the feasibility of transplanting similar watershed parameters,this paper combines DEM and land use data and selects multiple similarity indexes representing hydrological characteristics to discriminate the similarity relationship of 10 watersheds in Wuqiangxi Basin by relative root mean square error method and hierarchical clustering method.Similar watershed parameters are transplanted and flood forecasting is carried out.The results show that the relative root mean square error of slope distribution in Taoyi Watershed and the watershed near Wuqiangxi Dam site is 0.44,the relative root mean square error of topographic index is 0.25,and the distance coefficient of the two watersheds calculated by hierarchical clustering method is 0.11.Some parameters of the Taoyi Watershed are transplanted into the watershed near Wuqiangxi Dam site,and the flood forecast is carried out through the Xin'anjiang model.The flood simulation results are better.关键词
