Sediment management in hydropower dams is of crucial importance, both for economic as ecologic reasons. Sedimentation in reservoirs may lead to loss of active storage and blockage of the inlets and consequently loss of economic value. For the ecological value (e.g. fish habitat) a proper mix of sediment is important. Many hydropower companies around the world are therefor interested to improve the sediment management of the reservoirs. J-Power, the largest electric utility in Japan, is actively seeking to jointly develop knowledge and techniques to improve their gate operation for better management of the sediment trapped in the reservoirs and spread of sediment downstream.
