Analytical solutions are presented for calculating sedimentation and useful life of reservoirs using the trap efficiency relationships. Empirical equations are fitted to Brune's trap efficiency curves and these equations are combined with the differential equation of the rate of reservoir sedimentation to produce the final solution.

Sedimentation and useful life of reservoirs - ScienceDirect

RESERVOIR SEDIMENTATION General. - All reservoirs formed by dams on natural water courses are subject to some degree of sediment inflow and deposition. The problem confronting the project planner is to estimate the rate of deposition and the period of time before the sediment will interfere with the useful function of the reservoir.
