Hydraulic jump in one-dimensional flow [PDF]
The European Physical Journal B - Condensed Matter and Complex Systems, 2005 In the presence of viscosity the hydraulic jump in one dimension is seen to be a first-order transition. A scaling relation for the position of the jump has been determined by applying an averaging technique on the stationary hydrodynamic equations. This gives a linear height profile before the jump, as well as a clear dependence of the magnitude of ...

Estimating the effect of sand-roughened bed on hydraulic jump characteristics using heuristic models
Results in EngineeringThe hydraulic jump occurs in open channels and downstream of hydraulic structures because these features change the flow regime from super-critical to sub-critical. To prevent downstream channel erosion and guarantee the construction of a hydraulic jump,
