Question

If a looping is present in the ridge line they how can that area be irrigated with?

(a) Distributary

(b) Tributary

(c) Weir

(d) Canal

This question was posed to me during an internship interview.

My question comes from Canal Irrigation System in division Canal Irrigation System of Irrigation Engineering

Answer 1

The correct answer is (a) Distributary

To explain I would say: The alignment of watershed canal does not run along the loops of the ridge line, but instead they run in straight line leaving a small area between the alignment and the looped ridge line. This area can be irrigated with help of a distributary which starts from the starting of the loop of the ridge line and runs along the ridge line and finally joins the alignment at the end of the loop.
