3.2 Topic 8: Open Channel Flow - University of Texas at Austin

14 Gradually Varied Flow Profiles Physical laws governing the head variation in open channel flow 1) Gravity (So) is the driving force for flow 2) If So = Sf then dE/dx = 0 and flow is uniform (normal depth) 3) Gravity (So) is balanced by friction resistance (Sf) and longitudinal adjustment in specific energy (dE/dx)
