Reservoir sedimentation

LAKE MEAD, AZ/NV

Reservoir types Flood control Hydropower Flow regulation Recreation Reservoir water volume fluctuations allow flood attenuation Hydropower Flow regulation Steady release modulates downstream stage Recreation Water supply Spillway sets water balance

Sedimentation problems Sediment reduces storage capacity of reservoir, flood attenuation Sediment loading threatens dam integrity Downstream discontinuity of sediment

Sediment pathways Coarse sediment forms delta on upstream edge Coarsest suspended material forms pro-delta wedge Wash load may settle prior to discharge depending on water residence time

Example: Yali Reservoir, Vietnam

Q: How much of modern watershed sediment yield is stored in reservoirs instead of being exported to the ocean?
