(b) productive canal

(c) permanent canal

I have been asked this question in exam.

This key question is from Canal Irrigation System in portion Canal Irrigation System of Irrigation Engineering

Answer 1

Right answer is (b) productive canal

For explanation: After the development of the canal system the revenue obtained from the cultivators is such that it is more than the maintenance expenditure. This exceeding amount of revenue is so adjusted that it is about 2% of the cost of the canal system. With this rate, the total cost of the project will be recovered in about 50 years.
