The figure below shows flow under a sluice gate and over a sharp crested weir in a rectangular channel. a. Indicate on the figure in which section(s) of the channel flow is controlled from upstream and in which section(s) of the channel flow is controlled from downstream. b. Explain your answer from part a using the equation for the Froude number and the equation for the speed of a shallow wave.
