Question

Inlets and Outlets are inferior to aqueduct or super-passage type of work.

(a) True

(b) False

This question was posed to me in my homework.

The origin of the question is Cross Drainage in section Cross Drainage Work of Irrigation Engineering

Answer 1

The correct choice is (a) True

The explanation: Inlets though cheaper are not preferred nowadays since their performance has not been very satisfactory. They are used when the high flood drainage discharge is small. Similarly, a super-passage is inferior compared to an aqueduct and should be avoided whenever possible.
