Hydraulic jump is a phenomenon with destructive effects on the river bed and downstream the hydraulic structures. This study, based on experimental findings, presents a new method that can be used to prevent the detrimental impacts of the hydraulic jump downstream of hydraulic structures and to design optimal structures. In this empirical research, 135 experiments were conducted in an experimental flume where submerged vanes with angles of attack of 30 and 60°, as a novel intuitive method, were used with two different configurations and adverse slopes (0, −1.5% and −3%) to control hydraulic jump in the range of 4.58 < Fr₁ < 9.14. Based on the obtained results, the sequent depth and length of the hydraulic jump were, at most, decreased by 26.6% and 31.9%, respectively, with increasing the angle of attack of submerged vanes and the adverse slope of the bed. Also, the energy loss increased up to 7.7% in the case of φ = 60°, d = 0.2 m, and S = −3%. To calculate the sequent depth and length of the hydraulic jump, new equations were expressed through the analysis of the effects associated with the angle of attack, adverse slope, and vane configuration. All data resulting from proposed equations were then compared and validated with the experimental data.

水跃 是对河床及下游水工建筑物造成破坏性影响的现象。这项研究基于实验结果，提出了一种新方法，可用于防止水工结构下游水跃的有害影响并设计最佳结构。在这项实证研究中，在实验水槽中进行了 135 次实验，其中使用攻角为 30 和 60° 的浸没叶片作为一种新颖的直观方法，采用两种不同的配置和不利的坡度（0、-1.5％和-3） %) 将水跃控制在 4.58 < Fr ₁范围内 < 9.14。根据所得结果，随着浸没叶片攻角和床面逆坡度的增加，后续水跃深度和长度最多分别减少26.6%和31.9%。此外，在 φ = 60°、d = 0.2 m、S = -3% 的情况下，能量损失增加至 7.7%。为了计算水跃的后续深度和长度，通过分析与攻角、逆坡度和叶片配置相关的影响，表达了新的方程。然后将所提出方程得出的所有数据与实验数据进行比较和验证。
