Predicting Hydraulic Jump Length on Rough Beds Using Data-Driven Models [PDF]
Journal of Rehabilitation in Civil Engineering, 2018 The hydraulic jump can be used for some purpose such as dissipating the flow energy in order to prevent bed erosion; aerating water and facilitating the mixing procedure of chemical that used for water purification.

Predicting submerged hydraulic jump characteristics using machine learning methods
Water supply : the review journal of the International Water Supply Association, 2021 Hydraulic jump typically occurs downstream of hydraulic structures by converting the supercritical to subcritical flow regimes. If the tail-water depth is greater than the secondary depth of the hydraulic jump, the jump will be submerged (SHJ).

Modeling Length of Hydraulic Jump on Sloping Rough Bed using Gene Expression Programming [PDF]
Journal of Artificial Intelligence and Data Mining, 2020 Generally, length of hydraulic jump is one the most important parameters to design stilling basin. In this study, the length of hydraulic jump on sloping rough beds was predicted using Gene Expression Programming (GEP) for the first time. The Monte Carlo

SPH Simulation of Hydraulic Jump on Corrugated Riverbeds
Applied Sciences, 2019 This paper presents a numerical study of the hydraulic jump on corrugated riverbed using the Smoothed Particle Hydrodynamics (SPH) method. By simulating an experimental benchmark example, the SPH model is demonstrated to predict the wave profile ...

Hydraulic flow through a channel contraction: multiple steady states [PDF]
, 2007 We have investigated shallow water flows through a channel with a contraction by experimental and theoretical means. The horizontal channel consists of a sluice gate and an upstream channel of constant width $b_0$ ending in a linear contraction of ...

The hydraulic bump: The surface signature of a plunging jet [PDF]
, 2013 When a falling jet of fluid strikes a horizontal fluid layer, a hydraulic jump arises downstream of the point of impact provided a critical flow rate is exceeded.

Effect of Gate Opening Height on the Hydraulic Jump Characteristics in an Open Channel [PDF]
Journal of Applied Fluid MechanicsHydraulic jump is often used to dissipate energy of flow in open channels. Despite extensive study on hydraulic jump, effects of tail gate operation on hydraulic jump remains underexplored in the standard literature.

Investigation of Pressure Fluctuations of Hydraulic Jump on Rough Bed [PDF]
علوم و مهندسی آبیاری, 2018 A hydraulic jump is a sudden transition from a supercritical to subcritical flow with a broad range of turbulence Scales. The fluctuating nature of the flow such as oscillations of jump toe position and production of large eddies are visible in pseudo ...

Turbulent shear stresses in hydraulic jumps, bores and decelerating surges [PDF]
, 2011 In an open channel, a sudden rise in water level induces a positive surge, or bore, that may develop as a hydraulic jump in translation. When the surge propagates against an adverse slope, it decelerates until it becomes a stationary hydraulic jump. Both

Experimental investigation on the characteristics of hydraulic jump in expanding channels with a water jet injection system [PDF]
Journal of Hydraulic Structures, 2022 The high flow velocity downstream of weirs and gates can cause the destruction of erosive beds in rivers or even non-erosive channels. To reduce the flow's kinetic energy, structures are needed to consume this energy.
