摘要

Sediment bypass tunnels are very important and effective engineering practices in reducing the sedimentation rate of reservoirs and extend the reservoir lifespan. This type of sediment management technique is sometimes expensive, applicable only in the case of medium size reservoirs. The medium size refers not only to that of the reservoir, but also to the hydrological size of the catchment. In Japan, Miwa Dam (Tenryu River) and Asahi Dam (Shingu River) are good examples for sediment bypass tunnels where routing incoming sediments directly to downstream reaches. These dams are practically using sediment bypass tunnel successfully to realize a sustainable reservoir management.
