Design the best cross-section of a trapezoidal canal to irrigate a field of 1000
hectare, where the water supply is 100 (m³/hectare/day). Knowing that the side
slope is 1:1 and bed slope of 10 cm/km. Use n = 0.02.
Hint: Q = water duty * area = (100*1000) / (24*3600) = 1.157 m³/s
Find the relationship bet. b & d. then solve.
