Question

Design a canal culvert 75 metres long to pass a normal full supply discharge of 4 m3/s with 0.3m head loss. The upstream and downstream canal parameters are as given in the following. Ymax=1.40 m Vmax=0.830 m/s

Ymin=1.05 m V min =0.74 m/s

At 5 m3/s, the normal upstream depth of flow = 1.28 m,

assume a square box section DxD is to be used with a rounded entrance so that K1=0.30. if R = D/4 for a single box section
