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

So, the equation for f(D) is indeed f(D)=0, indicating that the derived equation satisfies the…

Develop an equation for the transmitted wave height behind a vertical wall extending a depth d into the water of depth h, based on the concept that the wall allows the wave power below depth d to propagate past. Qualitatively, do you believe that your equation for the transmitted wave height will under- or overestimate the actual wave height ? Discuss your results.

Water flows steadily along a horizontal open channel of uniform width, over a broad-crested weir. The channel bed upstream from the weir (to the left) is d metres above the channel bed downstream from the weir (to the right), as shown in the figure below.
