6 An irrigation channel has a cultivable command area of 80% of the GCA of 75000

hectares. The intensity of irrigation is 40% for kharif and 50% for rabi seasons. Duty at the

field is 825 hectares per cumec for kharif and 1425 hectares/cumec for Rabi crops. If the

canal losses are 18%,compute the capacity of canal.

crop, commanded by a canal taking off from a storage tank. Taking a time factor for a canal

to be 13/20, calculate the discharge required at the head of the canal, if the capacity factor

is 0.8, and determine the design discharge.
