Question

What type of fall does diagram represent?

(a) Simple Vertical Drop Fall

(b) Inglis Fall

(c) Straight Glacis Fall

(d) Ogee Fall

This question was addressed to me in examination.

Enquiry is from Canal Falls in section Canal Falls of Irrigation Engineering

Answer 1

The correct choice is (a) Simple Vertical Drop Fall

Best explanation: The diagram gives clear image that in this fall a high crested fall takes place into the water cushion below. There is no clear hydraulic jump or energy dissipation, as the velocity jet enters the deep pool of downstream. Hence it is a simple vertical drop type fall.
