Abstract

This paper analyzes runoff and soil loss in relation to the rainfall regimes and land use changes in a small mountainous watershed in the Three Gorges Area (TGA) of China. Based on 10 years of rainfall measurements and K-means clustering, 152 rainfall events were classified into 3 rainfall regimes. The mean statistical features of different rainfall regimes display a marked difference. Each rainfall regime results in differing levels of runoff and erosion. The study was conducted in the Wangjiaqiao watershed, in Zigui County of Hubei Province, where a shift from paddy fields and cropland to forest and orchards is the most important land use change between the years 1995 and 2004. These land use changes caused significant decreasing trends in runoff and sediment load
