Stepped spillways are spillways provided by steps that are used to dissipate energy and reduce the scour and erosion that occur at the end of the hydraulic structures. Since the spillway is one of the parts of the dam used to get rid of excess water

Stepped spillways are specialized hydraulic structures crafted to optimize the effective dissipation of hydraulic energy along stepped chutes. The central objective is to scrutinize and improve the mitigation of flow separation occurring from the oge

Horizontal step surfaces are the traditional design of stepped spillways, intended for certain discharges. However, they do not perform satisfactorily at larger discharges. To improve this, layouts with shaped step surfaces, both downward and upward,

The stepped spillway of a dam is a crucial element that serves multiple purposes in the field of river engineering. Research related to flood control necessitates an investigation into the dissipation of energy over stepped spillways. Previous resear

To protect the dam body and downstream area, spillways should be built. Because the difference in water level upstream and downstream spillways is usually very big, energy dissipation facilities should be introduced. Stepped spillways were discovered

In this study, curved risers stepped spillways models based on the increasing angle of suspension were tested to check for improvement in energy dissipation and pressure distributions. Four fourteen-steps stepped spillway models with a slope 1:0.84 w
