Abstract
Gullies are extensively distributed in the Upper Yangtze River Basin, SW-China. But the impact of these gullies on total sediment output is still not clear because there is no reliable technique for quantifying this issue. The target areas of our research are the dry-valleys located in the upper Yangtze River Basin, SW-China. Our study objectives are to: a) quantify gully erosion rates as affected by land use change over the last 100 years, and b) to assess relative importance of different erosion types including gully and rill or sheet erosion in sediment production in selected gully catchments.
