Abstract: The transition from supercritical to subcritical flow in sloping channels is systematically investigated under a wide range of slopes. The hydraulic conditions for the formation of D‐jump, where the entire jump is formed ...

Abstract: Supercritical flow below a sluice gate in a horizontal smooth rectangular channel is investigated to explain the effect of the inflow condition on the characteristics of the hydraulic jump. The movement of jump location ...

Abstract: Two-dimensional turbulent free-surface flow with Froude numbers close to 1 is considered. The roughness of the bottom of the channel is allowed to vary with the space coordinate, leading to small variations in the bottom ...

Abstract: In submerged flows below an expanding outlet, both symmetric and asymmetric flows are observed. The hydraulic conditions required to form a symmetric submerged jump are necessary for design purposes. In this study, the ...

Abstract: The flow conditions of undular jumps for fully developed inflow condition have been investigated systematically. If the inflow Froude number is larger than 1.2, an undular jump has lateral shock waves near the toe of the ...
