Abstract

Changes in sediment budget and quantification of sediment fluxes of a small Mediterranean sub-Alpine river catchment (Charanc catchment, Southern French Alps, are estimated for the last 20,000 years using a GIS-based approach and 3D palaeotopographic reconstructions. Following field surveys, a high-resolution morphometric map was established. Ten 14C ages of sub-fossil trees and charcoal beds were compiled. It is shown that computed specific erosion rate is maximum from 20,000 to 14,500 cal. BP., and the sediment budget shows a change to a sedimentation regime at 14,500 cal. BP. The AA. conclude that changes in erosion regime are probably climate-driven
