ABSTRACT
Indus River is one of the world’s highest sediment carrying rivers. The main factors causing high sediment load in the river are mainly the moving glaciers crushing rocks, comparatively young nature of geologic formations in the river basin and steep slopes in the area. When such rivers are impounded, severe sedimentation takes place in the reservoir. Sedimentation in the reservoir then causes some serious problems in the reservoir operation, amongst which the major ones are the loss of water storage capacity, risk of clogging of low level tunnel outlets, abrasive action of sediment laden flows on power turbines causing increase in maintenance costs.
