A wide rectangular channel is carrying the discharge of 5m3/s per meter width. The channel is a lined with the material such that the manning’s roughness coefficient value is 0.010. Calculate the shear stress produced at the bottom of the channel, if the reduced level of the bed is falling at the rate of 1.6 m in 1 km length.
