Abstract

In the experimental catchments near Draix (France), soil erosion rates have been measured in the past at the plot scale and at the catchment scale. More recently, erosion rates have been determined by means of dendrogeomorphic techniques in 3 monitored catchments of the Draix basin. The dendrogeomorphic record of point-scale soil erosion rates matches very well with soil erosion rates measured in the Draix basins. Based on the point-scale measurements and dendrogeomorphic results obtained at the point scale, a linear regression model involving slope angle was derived and coupled to high-resolution slope maps obtained from a LiDAR-generated digital elevation model so as to generate high-resolution soil erosion maps. The results demonstrate that dendrogeomorphic analyses of roots clearly have significant potential
