A channel step, shown in the figure below, is in a 12 m wide channel with discharge, Q, of 46 m3/s. The flow depth at section 1 is 1.6 m and the step height is 0.4 m. The bed of the channel, upstream and downstream of the step, is horizontal and smooth. Part A. Sketch on the figure the variation of the pressure with depth at sections 1 and 2, and on the verticalface of the step. Sections 1 and 2 are located far enough from the step for the velocity to be essentially horizontal and uniform. Part B.
