(b) It is required to design a new canal to carry a flow due to a heavy storm runoff in a new township to mitigate flash flood problem. The canal is to carry 40 mº/s of water, and to be cut in an alluvial soil of median size 1.0 mm. The canal is a trapezoidal shape with side slope 0.5 H: 1 V. Use Lacey theory to design the canal. Also calculate the Manning's n.
