A Laboratory Study Attempt of Flow and Energy Dissipation in Stepped Spillways
Journal of Engineering, 2018 A new laboratory study conducted on stepped spillways in order to investigate their efficiency of dissipating flow energy. All previous study on stepped spillway indicated that the flow energy dissipation decreased as increasing in discharge.

The effect of gabion steps on the hydraulic jump characteristics downstream of stepped spillways
Water ScienceGabion steps on stepped spillways can be a suitable alternative to solid impermeable steps due to their economic advantages, ease of implementation, stability through water pressure reduction, and energy dissipation.

A New Type of Pre-Aeration Stepped Spillway
Aiming to increase energy dissipation and prevent the cavitation potential of a traditional stepped spillway (TSS) at large unit discharges, a kind of pre-aeration stepped spillway, called a hydraulic-jump-stepped spillway (HJSS), is introduced in this ...

Jet Flow on Stepped Spillways [PDF]
Journal of Hydraulic Engineering, 1995 The authors provided interesting data on stepped spillway flows. The writer would like to add some information on flow resistance of skimming flows and discuss the energy dissipation on stepped chutes. It will be shown that the author's results are not dissimilar with results previously obtained by other researchers (table A1).

Hydraulic Design of Stepped Spillways
Journal of Hydraulic Engineering, 2003 An experimental study on a large model flume using fiber-optical instrumentation indicated that the onset of skimming flow is a function of critical depth, chute angle, and step height. Uniform mixture depths that determine the height of chute sidewalls and uniform equivalent clear water depths are described in terms of a roughness Froude number ...
