Question

The canal water flows freely under gravity in which of the following CD works?

(a) Aqueduct and Super passage

(b) Super passage and Syphon

(c) Canal Syphon and Aqueduct

(d) Level-crossing and inlets outlets

The question was posed to me by my school teacher while I was bunking the class.

My question comes from Types of Cross Drainage Work in chapter Cross Drainage Work of Irrigation Engineering

Answer 1

The correct option is (a) Aqueduct and Super passage

The best I can explain: In canal syphon and syphon aqueduct, canal water flows under symphonic action. The canal and the drainage system approach each other practically at the same level in CD works like Level crossing and inlets and outlets.
