主 题:Hydro-morphometric parameters correlation analysis multiple linear regression hierarchical ascending classification sub-catchments Tshopo river
摘 要:The most characteristic hydro-morphometric parameters controlling water flow in the Tshopo catchment have not yet been *** analysis,multiple linear regression and hierarchical ascending classification were applied to all the data in order to identify the most characteristic variables that significantly influence water flow velocity,and to group together physically similar *** results highlight the importance of topography on water *** topographical variables,namely median altitude(H50),overall gradient(Dg)and specific gradient(Ds),have a significant influence(p-value≤0.05)on surface water flow velocity(Ve)in the Tshopo *** opposing groups(G1 and G2)of sub-catchments were identified,on the one hand the sub-catchments belonging to the upper and middle course of the Tshopo(SBV1,SBV2,SBV3 and SBV5)and on the other the sub-catchments of the lower course(SBV6,SBV7 and SBV8).The first group is characterized by moderate relief(Ds ranging from 53.19 to 73.6 m),while the second group has low relief(Ds ranging from 18.1 to 29.43 m).
