Water is flowing in a rectangular channel 5 m wide at a normal depth of3 m. The channel is running on a slope of 0.0005 m/m and carries a discharge of 22.5 m3 /s. The representative roughness element of the bed material is 0.01 m. (a) Determine the Chezy C value for this channel. (6) Compute the value of the shear stress imparted co the channel boundary. (c) Using the velocity equation for fully rough flow, with the representative bed element as t:, compute the velocity profile for this condition. (d) Using the velocity obtained at a distance of2.5 m from the bed as v,,,, compute the velocity profile by the 1/ 7 power law and compare with the results from part (c).
