Question

Which of the following factor do not affect seepage loss?

(a) Underground water-table condition

(b) The porosity of the soil

(c) Physical properties of the canal water

(d) Prevailing wind velocity in the region

This question was posed to me in an online quiz.

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

Answer 1

Correct choice is (d) Prevailing wind velocity in the region

For explanation: The loss due to seepage is the most significant so far as irrigation loss from canals is considered. The porosity of the soil, underground water-table condition, condition of the canal system, and physical properties of the canal water are all factors affecting seepage loss.
