Nieuw project gestart: Improving sediment management in river systems with reservoirs

Geplaatst op:

Sediment management in hydropower dams is of crucial importance, both for economic and environmental 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 and timing of sediment flushing to the downstream is important. Many hydropower authorities around the world are therefore interested in improving the sediment management of the reservoirs. J-Power, the largest power company 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.

This project is a follow-up of the previous TKI project with J-Power. In addition, J-Power wants to assist to address the sediment related issues in hydropower dams in Nepal (mainly Run-of-the-River) by involving Deltares and enhancing the cooperation with local institutions and companies that are active in this field.
