A global challenge
Figure 2: Modelling bottom level change in the 3S reservoir cascade using the CASCADE model (see Figure 1 for geographic location). Results consider the different sediment flux and grain size at each dam location from different natural sediment transport and the sediment trapping in upstream dams. Each square marker in panel A shows the change in bottom level in a specific reservoir compartment up to 2050 (color code). Sedimentation in reservoirs can be evaluated in more detail for specific dams (B), and different patterns of reservoir storage loss can be evaluated along the longitudinal section of each reservoir (C).
