Sedimentation problems on regulated rivers are considerably different from natural rivers. Problems include sedimentation in reservoirs, channel effects downstream of dams, and in-stream flow requirements for maintenance of channels and fisheries. ... Moreover, in-stream mining can cause multiple effects on fish habitat.
