A long concrete irrigation channel of rectangular section and base width 3m discharges as a free overfall. The flow is critical at the overfall and the discharge is 0.5m3/s. The channel is on a slope of 1 in 10,000 and has a Manning coefficient of 0.015.

(a) Calculate the uniform and the critical depth.

(b) Sketch and name the particular type of backwater curve occurring in this case.
