2 An Earthen Channel Is Excavated In A Sandy Clay Bed With Particle Size Of Dso 3 0 Mm Where The Bed Particles Are Ve 1 (133.99 KiB) Viewed 17 times

2. An earthen channel is excavated in a sandy clay bed with particle size of dso = 3.0 mm where the bed particles are very rounded. It conveys a discharge of Q= 10.3 m3/s over a slope of S=0.00015. If the bottom width to depth ratio of the canal is b/y=8,0, design the canal cross-section using the "unit tractive force" method. The minimum permissible velocity is confined to Vmin = 0.5 m/s to prevent siltation problem. [20 marks] Fg b
