A long, straight open channel has a base width of 1 m and sides that slope outwards at 60◦ to the horizontal. The bed has a uniform slope of 1 in 250 and the channel ends in a free outfall. A small surface wave travelling slowly upstream becomes stationary at a section where the boundary surface is slightly smoother. If the normal depth of flow is 150 mm and the Chézy coefficient is given by Km1/6, where m represents the hydraulic mean depth, estimate the value of K for the smoother surface and the mean shear stress on this surface.
