Background: Hydraulic jump is considered the most appropriate option for designers to dissipate energy through stilling basins. Methods: Tests on a screen that produced submerged hydraulic were conducted of water passing beneath vertical gate. Various positions in sudden expanding basin investigated. In comparison no-screen case, effect downstream gate surface profile was also Results: The best...

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 ...

Hydraulic jumps have immense practical utility in hydraulic engineering and allied fields, such as energy dissipater to dissipate the excess energy of flowing water downstream of hydraulic structures (spillways and sluice gates), efficient operation of flow measurement flumes, chlorinating of wastewater, aeration of streams which are polluted by biodegradable wastes and many other cases. The le...

The available studies for estimating the characteristics of hydraulic jump are only for artificial or natural beds, and very limited researches have simultaneously considered artificial and natural beds. The aim of this study is to present comprehensive equations and models for predicting the characteristics of hydraulic jump in artificial and natural rough beds with various dimensions, arrange...

In this paper, an experimental investigation was carried out to study the turbulent flows and flow characteristics through sloping and adversely sloping rectangular culverts in a rectangular channel of constant width using Laser Doppler Velocimetry (LDV). Also, experimental study was carried out to investigate the characteristics of the hydraulic jump occurring in a sloping and adversely slopin...

In an open channel, a hydraulic jump is the rapid transition from superto sub-critical flow associated with strong turbulence and air bubble entrainment in the mixing layer. New experiments were performed at relatively large Reynolds numbers using phase-detection probes. Some new signal analysis provided characteristic air–water time and length scales of the vortical structures advecting the ai...
