A Study of the Sedimentation and Storage Capacity Depletion of a Reservoir

Abstract Theoretical and empirical equations have previously been proposed to compute the sediment trap efficiency of a reservoir. The were developed by analyzing limited amount field data for reservoirs in selected areas; thus, their suitability is restricted regions with similar hydrological characteristics. In this study, trap-efficiency equation, which accounts dynamic behavior sedimentation hydraulic conditions reservoir, was deduced from principle mass conservation. Using approximate analytical expression storage capacity reservoir obtained. Both applied investigate real-life problems involving impacts sedimentation, predicted solutions compared results theoretical equations. investigation reveal that are capable simulating trapping depletion characteristics large reservoirs, measure adverse effect on performance structures. These can potentially be incorporated into large-scale watershed model estimating budget.
