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.
