A simple theory is developed whereby an expression for the length of the classical hydraulic jump is obtained. The theory is based on the postulate that the roller region of the jump is composed of a chain of energy containing eddies. The theoretical expression is compared with existing experimental data.

Ski jumps are a standard element of dam spillways for an efficient energy dissipation if takeoff velocities are large, and stilling basins cannot be applied. This laboratory study investigates the hydraulic performance of a triangular-shaped, rather than the conventional circular-shaped, bucket placed at the takeoff of ski jumps.

Undular Hydraulic Jumps in Circular Conduits
Journal of Hydraulic Engineering, 2002Undular hydraulic jumps in circular conduits are considered with an experimental approach. Based on previous findings in rectangular channels, this research indicates differences in terms of shape effects. All present results depend on the filling ratio of the upstream conduit flow in addition to the upstream Froude number.

Given the simplicity of channel geometry and the significance in the design of stilling basins, the CHJ received considerable attention during the last sixty years. Although first described by Leonardo da Vinci in the 16th century, it was only in 1820 when the Italian Bidone published the first test results (see Macagno, 1967, who presented excerpts of

An asymptotic order-of-magnitude description is given of the structure of a circular laminar hydraulic jump for large values of the Reynolds and Froude numbers of the flow entering the jump. The results are compared with numerical solutions of the boundary layer equations for the flow in a liquid layer on a horizontal disk and with experimental results

The results of an extensive fundamental study of the so-called spatial hydraulic jump are presented. After an introduction to the hydraulic problems involved in the computation and design of abruptly or gradually enlarged stilling basins, some information about the most important references is added.
