A trapezoidal channel (Manning, n = 0.012) is to be designed to carry a discharge of 14 m3/s at a slope of 0.003. The sides slope is to be fixed at 1V: 1.5H. Determine the dimensions of the channel based on the best hydraulic section criteria. Check the adequacy of the design in term of its Froude number.

3. a) A trapezoidal open channel is being designed to convey a discharge of 11.0 m3 /sec. The channel will be excavated into clay and will have the following properties: side slope with m = 1.5, bottom slope of So = 0.001, Manning’s n = 0.022, and bottom width b = 1.0 m. For these conditions is there a risk of channel erosion? b) The earth-works contractor that will carry out the excavation suggests that the side slope angle can...
