Question

What is the main purpose of the canal outlet?

(a) To Connect Head with a Minor Channel

(b) To Avoid Leakage

(c) To Avoid Exit Gradient

(d) For Proper Discharge

I had been asked this question by my college director while I was bunking the class.

My doubt is from Regulation Modules topic in section Regulation Modules and Canal Structure of Irrigation Engineering

Answer 1

Correct choice is (b) To Avoid Leakage

For explanation I would say: The canal outlet is a small structure that is built at the head of the watercourse so as to connect it with a distributary channel or a minor channel.
