T1 - Recovery of riverbed features and invertebrate community in degraded channels by sediment supply through bypass tunnel T2 - Proc. 12th Int. Conference on Hydroscience and Engineering, Tainan, Taiwan N2 - Sediment, which deposits and damages the function of reservoirs, is an essential element of aquatic habitats in downstream ecosystems. We reviewed ecosystem features of degraded channels associated with sediment deficiency below dams and ecosystem responses to changes in sediment conditions after management practices in Japan. Sediment bypass tunnel (SBT) is an effective way to transport sufficient amount of sediment to downstream ecosystems. Based on a concept of suitable mass and size of sediment for ecosystem, some effects and limitations of SBT on downstream ecosystems were discussed.
