Question

Aggradation due to sedimentation in the reservoirs of dams can cause

Answer 1

Explanation:

Aggradation or deposition of sediments on the reservoir of dams can cause a great deal of reduction in storage capacity and also can cause damage to the structure in downstream. Thus reducing the flow of water in the stream and also creating rise in water levels and water logging.

This, reduction of storage capacity can cause blocking of the gates in the dams and also creating a rise in the water level dangerously.

Answer 2

Explanation:

Aggradation or displacement of sediments on the storage of dams can produce a great deal of reduction in storage capacity and also can cause damage to the construction in downstream. Thus reducing the flow of water in the stream and also producing a rise in water levels and waterlogging.

Hence the aggradation must be avoided and it can be done via removing the rough surface in the reservoir.
