CFD Modelling of a Stepped Spillway with Various Step Layouts [PDF]
Mathematical Problems in Engineering, 2019 A traditional stepped spillway is prone to cavitation risks. To improve its hydraulic behaviors, distorted step faces and pool weirs are devised. By numerical modelling, comparative studies are conducted to look into the flow features. The pressures on step surfaces of the unconventional layouts exhibit 3D distributions.

Study Effect of Fluctuations of Pressure Factors of Stepped Short-throat Shaft Spillways on Hydraulic Coefficient [PDF]
Journal of Hydraulic and Water Engineering, 2023 Stepped spillways discharge more flow through themselves than smooth spillways theoretically. Therefore, understanding the flow behavior of these spillways can lead to better and more efficient use. In addition, the use of vortex breaker.
