What slope of an open channel is needed to keep the velocity of water in it below 0.75 m/s to prevent scouring of the bottom. The channel has a trapezoidal cross section area with a bottom width of 5.0 m and sides with a slope of 4:1 (horizontal to vertical) and is lined with fine gravel and is to carry 16 m3/s flow. (n= 0.02).
