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.

Evaluation of Energy Dissipation and Hydraulic Characteristics of Flow on Simple and Inclined Stepped Spillways using FLUENT Model [PDF]
علوم و مهندسی آبیاری, 2018 Stepped spillways are hydraulic structures which due to the high energy loss of flow have important role in reducing dimensions of stilling basin of downstream of the dams and consequently their economical design.

Study of Conveniency of Using Stepped Spillway in Roller Compacted Concrete Dams (RCCD) [PDF]
Engineering and Technology Journal, 2009 A suggested design of Bastora stepped spillway has been taken as a prototype to build a physical wooden model with scale of 1:20 (Lm/Lp). Experiments have been carried out on the model with slope of upward inclined steps of 420, 280, 140 and 00.

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.

Aeration characteristics for skimming flow along the pre-aerator stepped spillways
Shui kexue jinzhan, 2014 Pre-aerator stepped spillways,where the aerator is placed prior to the primary step in the stepped spillway,can form a cavity chamber at the bottom to produce enough aeration concentration to avoid the cavitation erosion.
