Analysis of Energy Dissipation of Interval-Pooled Stepped Spillways [PDF]
Entropy, 2022 The water flow characteristics over an interval-pooled stepped spillway are investigated by combining the renormalization group (RNG) k-ε turbulence model with the volume of fluid (VOF) interface capture technique in the present study.

Location of inception point of alternating steps stepped spillways
Sulaimani Journal for Engineering Sciences, 2023 This study explored the effects of flat-stepped spillways having alternating steps on the inception point location. Two wooden stepped spillways with a longitudinal slope of 26.6° were constructed in a rectangular flume and tested at various discharges ...

Improving energy dissipation on stepped spillways using breakers
Ain Shams Engineering Journal, 2018 Stepped spillways have many applications in dam structures, and river engineering. Moreover, stilling basins can be constructed with lower costs as energy dissipation by adding appurtenances to these stilling basins.

Re-Aeration on Stepped Spillways with Special Consideration of Entrained and Entrapped Air
Geosciences (Switzerland), 2018 As with most high-velocity free-surface flows, stepped spillway flows become self-aerated when the drop height exceeds a critical value. Due to the step-induced macro-roughness, the flow field becomes more turbulent than on a similar smooth-invert chute.

Numerical investigation of simultaneous effect of end sills and roughness on flow characteristics in V-shaped stepped spillways [PDF]
Journal of Hydraulic Structures, 2021 The special configuration of V- shape stepped spillways increases energy dissipation and aeration compared to the smooth spillways due to the creation of many vortices near the steps. In this research, the energy dissipation in different types of stepped
