How is reservoir sedimentation estimated and managed?

Reservoir sedimentation estimation: (1) Sediment yield from catchment using USLE, sediment rating curves, or regional data, (2) Trap efficiency using Brune or Churchill curves based on capacity-inflow ratio, (3) Sediment distribution using empirical area-reduction method. Management strategies: (1) Watershed treatment to reduce erosion, (2) Sediment exclusion structures, (3) Sluicing through low-level outlets during floods, (4) Dredging (expensive), (5) Density current venting, (6) Flushing. Dead storage accounts for sedimentation; periodic bathymetric surveys monitor accumulation.
