Ueber die Kräfte, welche zwei unendlich dünne, starre Ringe in einer Flüssigkeit scheinbar auf einander ausüben können.
The flow inside the hydraulic jump is interpreted in terms of diffusion of a two-dimensional turbulent jet. The classical theoretical-experimental results of turbulent diffusion can be consequently utilized and, on the basis of continuity and momentum equations, the water depth and the distribution of flow velocity for any cross section are shown to be determined for given Froude number of upstream flow.
