Question

In order to reduce the CD works, the artificial canals are generally aligned along the ridgeline.

(a) True

(b) False

This question was posed to me during an internship interview.

My question is from Cross Drainage topic in section Cross Drainage Work of Irrigation Engineering

Answer 1

Correct choice is (a) True

Best explanation: Canal drainage works are generally not required when the canal reaches the watershed line unless the canal alignment deviates from the watershed line. The canal which takes off from the river has to cross a number of drains which move from the watershed towards the river before the watershed is reached.
