In the field of hydraulic constructions, restoring water within a stream is a very common issue. To avoid important and non-controlled modifications in streams, energy dissipation is often essential to convert a flow with high mechanical energy into a flow with low mechanical energy. In the works of dissipation, a regime change of the flow intervenes: at the entry of these works, it is torrenti...

A hydraulic jump is the sudden transition from a high-velocity impinging flow into a turbulent roller in an open channel. Substantial amounts of air are entrapped at the impingement point, and significant free-surface fluctuations take place above the roller. In the present study, some physical modelling was conducted in a relatively large sized facility. The flow conditions included a wide ran...

Many studies have been conducted on the characteristics of hydraulic jumps over horizontal basins. On sloping basins, however, few such studies have been performed so that the issue requires more investigation. A significant number of studies has also been conducted on basins with positive slopes but comparatively few have been carried out on basins with negative slopes. This study was carried ...

In this study, we examine the consistency of a gravity-based predictive theory for hydraulic jump, given by Kurihara [ Proceedings Report Research Institute Fluid Engineering (Kyusyu Imperial University, 1946), Vol. 3, pp. 11–33]; Tani [J. Phys. Soc. Jpn. 4, 212–215 (1949)] with phenomenological condition at jump Rayleigh [Proc. R. London, Ser. A 90, 324–328 (1914)]; and Watson Mech. 20, 481–49...
