The correct answer is (a) Critical Velocity (Vo)

Explanation: Eddies affect the formation of silting action in a channel brief investigation shows that the vertical component of these eddies try to move sediment up and the weight of sediment tries to bring it down, thus keeping the sediment in suspension. So, silting is avoided if sufficient velocity is generated to form eddies and keep the sediment in suspension. This velocity is called critical velocity.
