Suppose that you wish to assess the hazard posed by a hydraulic jump in a flooded river. The river channel can be assumed to have a uniform rectangular cross-section and you can safely measure the flow speed and depth downstream of the jump to be ud and hd, respectively. Take the gravitational constant to be g = 9.81 ms -2 where required. (a) (b) (c) (d) Derive an equation to determine the flow depth upstream of the hydraulic jump. Formulate the equation as quadratic in D such that f(D) = 0. Give f(D) in symbolic form, using only the downstream Froude number Frd and the ratio D of upstream depth to downstream depth. f(D) = Help
