Consider a rectangular channel with a variable width b and horizontal channel bottom, a) Obtain the equation of water surface profile (dy/dx) as function of Froude number and channel width change (db/dx) in a channel transition assuming that over a short distance x, the energy losses can be neglected. b) Using the equation you have obtained, draw the water surface profile if flow is subcritical and if there is an enlargement in channel cross section b in downstream section (2) and show your results on the graph of specific energy curve (E versus y curve).
