Question

On what basis for designing the regime state is obtained?

(a) Silt and Velocity of Flow

(b) Silt

(c) Velocity

(d) Depth of Channel

This question was posed to me by my college professor while I was bunking the class.

I'd like to ask this question from Stable Channels Design  in India in portion Sediment Transport and Irrigation Channels Design of Irrigation Engineering

Answer 1

Correct option is (a) Silt and Velocity of Flow

Explanation: The basis for designing a channel to be in regime state, whatever the amount of silt has entered the channel has to be kept in suspension, so that it does not settle down and get deposited in the channel anywhere. And the velocity of the flow in the channel should be such that it does not produce silt by eroding the banks and beds of the channel.
