An Analysis of Driving Factors on Water and Sediment Evolution

Abstract

The underlying surface has an influence on the characteristics of runoff and sediment characteristics in river basins. And the features of the different scales underlying surfaces have various effects on the runoff and sediment discharge in Kuye River. By analysing the concerned data from 1980 to 2013, this paper took 3 different scales watersheds in Kuye River Basin as the objects to study the influence of the underlying surface change on the runoff and sediment evolution in different scales and calculate the correlation degree of the driving factors by using grey relational analysis.
