Abstract

This paper was evaluating the impact of dams on suspended sediment load in Mekong River Basin. In this study, the dam module integrates with the distributed process-based sediment transport model to evaluate the potential future dams in the main stream impacts on suspended sediment load changes. The magnitude of sediment dynamics change is demonstrated with different dam scenarios analysis which are 3 existing, 5 under construction and 11 planned dams. The results from simulations show the reductions in annual suspended sediment load are range from a 20–33% for existing dams, 30–67% for under construction dams and 67–75% for planned dams. Moreover, the depletion on suspended sediment concentration are even greater (33–78%) due to the impact of future dams. Overall, the changes in sediment load and concentration can have significant indication for designed reservoirs and related sediment management.
