TY - CONF A1 - Auel, C. T1 - Sediment bypassing, a sustainable and co-friendly strategy against reservoir sedimentation T2 - VINGT SIXIÈME CONGRÈS DES GRANDS BARRAGES Vienne, Juillet 2018 N2 - Without adequate measures, reservoirs are not sustainable, neither the reservoir itself due to continuous sedimentation, nor the downstream ecosystem due to altered sediment continuity. Appropriate actions are inevitable and require a systematic sedimentation management. Sediment bypassing constitutes one effective strategy that routes sediment load around reservoirs during floods. A sediment bypass system has the advantage that only newly entrained sediment is diverted from the upstream to the downstream reach thereby re-establishing sediment connectivity. Hence, such a system contributes to a sustainable water resources management while taking the downstream environment into consideration. This paper gives a state-of-the-art overview encompassing design, bypass efficiency, hydraulics, challenges due to abrasion, positive effects on both downstream morphology and ecology, and makes design recommendations.
