Hydraulic Jump and Stilling Basins
Abstract For the change of flow type from supercritical to subcritical, a hydraulic jump forms. The phenomenon is first described and then the sequent depths are determined using the specific force principle. The profiles include the rectangular channel and the three standard cross-sections, namely, the circular, the egg-shaped and the horseshoe sections. Choking of the circular section on account of a hydraulic jump is also introduced. In the second part, relevant outlet structures are presented. The difference between the hydraulic jump and the stilling basin is explained. Subsequently a number of standard basin types are described and finally cases are enumerated which can lead to unplanned energy dissipation.
