Figure 1

Hydropower exploitation in (a) and geology of the Alpine Rhône catchment (b). (a) shows examples of a storage dam, a flow abstraction intake and the embanked main Rhône. The exploitation shows the extent to which tributaries are affected by storage or flow abstraction and is based upon Margot et al.48 (b) illustrates the geological architecture of the Rhône basin, the sites where 10Be samples have been collected and analysed for basin-averaged denudation rates21 are also shown. These data were used to establish a sediment budget for the Rhône basin, which resulted in the notion that Penninic units are underrepresented in the total sediment flux to Lake Geneva despite highest 10Be-based denudation rates. The External massifs have supplied most of the material21.
