Question

What is the effect of silting in channels?

(a) Reduced Discharge Capacity of Channel

(b) Causes Loss of Command

(c) Breaching of Canal Banks

(d) Failure of Irrigation Structures

The question was asked by my school principal while I was bunking the class.

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

Answer 1

Correct choice is (a) Reduced Discharge Capacity of Channel

For explanation I would say: The silting problem is very common in any kind of artificial channels, or we can say there is no natural or artificial channel with the silting problem. Silting interferes with the proper working of a channel, as it causes reduction in the channel section due to siltation, which thereby reduces the discharge capacity of the channel.
