Question

A canal aligned on the watershed saves the cost of constructed cross drainage works.

(a) True

(b) False

The question was asked during an online interview.

The query is from Canal Irrigation System topic in chapter Canal Irrigation System of Irrigation Engineering

Answer 1

Correct answer is (a) True

For explanation: By aligning a canal on the ridge, helps to irrigate the land on both sides of the canal. Moreover, the drainage flows away from the ridge, this gives an advantage in a way that the drainage does not cross a canal aligned on the ridge. Therefore the cost of construction of cross drainage works is reduced.
