A grass-lined trapezoidal channel is to be designed to carry a flow of 260 cfs. Determine a suitable Manning's first. The slope of the channel is 1.5 ft/2000 ft. The side slopes (same both sides), z = (1 vertical : 2 horizontal). Use a bly ratio of 1.25 and a maximum channel width b = 12 ft. Determine the design depth of flow for the channel () (b) Determine the other design parameters including the freeboard. (c) Is the flow in the channel under sub-critical or super-critical flow conditions? Why? Idl Sketch the profile cross-section of the channel with all necessary dimensions
