Correct option is (b) time factor

The explanation: No distributary is allowed to operate on all the days during any crop season to check for the dangers of over-irrigation leading to waterlogging and salinity. This ratio of actual operating period of a distributary to the crop period is called time factor. It is useful in computing the design capacity of a distributary.

The transplantation of rice takes 18 days and the total depth of water required by the crop is 60 cm on the field. During this transplantation period, rain starts falling and about 10 cm of rain is being utilized to fulfill the rice demand. Find the duty of irrigation water required for rice assuming 25% losses of water in watercourses.

Let us consider in a given area the plantation of a certain crop takes 20 days, and the total water depth required by this crop is 80 cm on the field. Find the duty of irrigation water required for the crop during this period. (a) Assuming 20% losses of water in the water courses, find duty at the head of the course. (b) Find the duty of the water at the head of the distributary, assuming 10% losses from the distributary head.
