A surface drainage trapezoidal channel has to be designed for a drainage area of 500 ha. The drainage coefficient for the soil and cropping system is 6 cm/day. The bed slope is 13 cm/Km and the Manning's n is 0.011. 1. What discharge in (m³/sec) should the channel be designed for? 2. Design the cross section of the channel, assume best hydraulic section.
