Question

A canal fall is provided when the available natural slope is flatter than the designed bed slope of the channel.

(a) True

(b) False

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

I would like to ask this question from Canal Falls in section Canal Falls of Irrigation Engineering

Answer 1

Right choice is (b) False

Easy explanation: When the ground has a steep slope heavy earth filling is required to construct the canal with a flatter bed slope. The difference between the natural slope and the designed bed slope is adjusted by constructing vertical falls or drops in the canal at a suitable interval.
