aggradation due to sedimentation in the reservoir of dams can cause
option : (A) reduction in the storage capacity
(B) damage to the structure in the downstream
(C) displacement of the populations near the downstream
(D) both (a) and (b)
Answers
Answer:
both a and b because due to sedimentation the capacity of fan reduces and damages the structure in down stream receives less percentage of water
Aggression due to sedimentation in reservoir of dam can cause reduction in the storage capacity as well as damage to the structure of downstream. Therefore the answer to the question is option d both a and b.
Sedimentation in the reservoir is defined as the deposition of solid material such a sand silt and clay below the water surface nearby the gate of dam which can damage the dam.
As the space is captured by sediments the water is displaced and hence there is reduction of storage capacity. The sediment also damage the structure of the dam in downstream as they continuously exert pressure on the gates of dam.
