Time series of annual data for basin-averaged mean annual temperature (a, Supplementary Materials 1); mean suspended sediment concentration (SSC) (b, Supplementary Materials 3); estimated annual loading (SSL) of suspended sediment to Lake Geneva (c, Supplementary Materials 3), and mean annual discharge (Q) (d, Supplementary Materials 3) at the mouth of the Swiss Rhône (g), Fig. 1a); rates of sediment extraction in the Swiss Rhône basin (e, Supplementary Materials 4); rates of flushing of abstraction intakes (f, Supplementary Materials 5) in zone I on Fig. 1a; and residuals from the modelled relationship between SSC (g) and SSL (h) and sediment extraction. In (f), a. indicates total flushing events and a+ the minimum number of flushes given possible night time flushing (see Supplementary Materials M5).
