Question

What vital factor is not considered in regime theories during the design of regime channels?

(a) Velocity of Flow in the Channel

(b) Type of Flow in the Channel

(c) Quantity of Sediment Entering a channel

(d) Area in which the Channel flows

This question was addressed to me in an international level competition.

Query is from Stable Channels Design  in India in division Sediment Transport and Irrigation Channels Design of Irrigation Engineering

Answer 1

Correct answer is (c) Quantity of Sediment Entering a channel

The best I can explain: The quantity of sediment load entering the channel from the head works plays an important role in designing the regime channels, as it controls the cross-section and shape of the regime channel. Moreover the design of regime channel is not complete until provisions are made for the effects produced by the actual quantity of sediment load present in the channel.
