Question

If the width of a river increases, the discharge per unit width will decrease and therefore, sediment carrying capacity will increase.

(a) True

(b) False

This question was addressed to me in an internship interview.

My doubt is from Sediment Transport in chapter Sediment Transport and Irrigation Channels Design of Irrigation Engineering

Answer 1

Correct answer is (b) False

Explanation: The sediment carrying capacity will reduce if the width of the river increases as the discharge per unit width will decrease. The deposition of the sediment will start which will increase the bed slope.
