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.
