Description :
Here, based on geomorphological observations, the AA. calculate the amount of river incision and interfluve denudation in the Meuse basin upstream of Maastricht since 0·7 Ma and show that the main response to tectonic forcing was incision. This allows to provide first-order estimates of the tectonic and climatic contributions to the denudation of the Ardennes. By comparison, the 10 Be-derived rate is overestimated, probably due to an overrepresentation of the erosion products of the rapidly incising valleys in the alluvial deposits.
