New Equations for Energy Dissipation down a Stepped Spillway
Journal of Engineering Research and Reports, 2022 Stepped spillways use their stepping nature to substantially dissipate energy in floodwater. Many researchers investigated the hydraulic and geometric relationships of the stepped spillway with a dam slope above 26.6o degrees that resulted in energy ...

SCOUR CHARACTERISTICS DOWNSTREAM CONVERGING SPILLWAYS [PDF]
The Egyptian International Journal of Engineering Sciences and Technology, 2016 Flow over spillways or underneath gates has a tremendous amount of potentialenergy, which is converted into kinetic energy downstream control structures.

International Journal of Science and Engineering Applications, 2022 Scrutinizing the considerable flow energy in a spillway plays a significant role in maintaining downstream dam safety, and due to this fact, the dimension of the stilling basin will be enormously reduced, and from an economical point-of-view ...

Water supply : the review journal of the International Water Supply Association, 2022 The effect of the end sill shape of steps for two-phase flow over the stepped spillways was investigated in this paper. A quantitative assessment approach has been applied. Experimental and numerical tests were used for stepped spillways with different

Journal of Engineering Research and Reports, 2022 In this paper, the authors reviewed the characteristics of a ball that descended one step each bounce of a flight of stairs and drew an analogy with a stepped spillway with a fully developed hydraulic jump. They used this concept with equations of motion,

Longitudinal distribution of extreme pressures in a hydraulic jump downstream of a stepped spillway
RBRH, 2017 The overflow system of a dam safely controls the water level of a reservoir. The design of these structures should predict the damage caused by the action of the turbulent flow to which they are subject to.

Energy dissipation performance of the trapezoidal stepped spillway
Journal of Engineering Research, 2021 Stepped spillways are a more effective type of spillway in energy dissipation than conventional chute channels. Therefore, the dimensions of the energy breaker at the downstream of the stepped spillways are lower.

Stepped spillway flows and air entrainment [PDF]
Canadian Journal of Civil Engineering, 1993 Stepped spillways have become a popular method for handling flood releases. The steps significantly increase the rate of energy dissipation taking place on the spillway face and reduce the size of the required downstream energy dissipation basin. The compatibility of stepped spillways with roller compacted concrete and gabion construction techniques ...

Experimental and numerical simulation of flow over stepped spillways
Applied Water Science, 2018 Stepped spillways are used in the construction of dams, river engineering and soil conservation projects. Energy dissipation in this structure due to the presence of several steps is high, so the construction costs for stilling basin are reduced.
