Design a channel (assuming a rigid boundaries) to irrigate 54,430 hectares at a rate of 60
 /ha/day. The soil allows side slope of 1: 1,
 = 0.025, and the bed slope is 10 cm/km. Find the channel dimensions for each of the following cases:

a. the maximum allowable velocity being 0.7 m/s

b. the maximum allowable boundary shear stress 0.05 lb/

c. V =
