Air-water flows on stepped spillways with inclined steps [PDF]
Australasian Fluid Mechanics Conference (AFMC), 2020 Stepped spillways have been constructed worldwide and the overflow is characterised by intense turbulent dissipation and strong self-aeration. The current study investigated experimentally the two-phase flow properties on stepped chutes equipped with inclined downward steps.

Energy Dissipation on Stepped Spillways [PDF]
Journal of Hydraulic Engineering, 1995 The author 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.

Stepped spillways with aerators: hydrodynamic pressures and air entrainment
RBRH, 2021 The possibility of damage due to the phenomenon of cavitation leads the design of stepped spillways considering maximum specific discharges of 15 to 30 m2/s, a limit considerably lower than that practiced on smooth chutes.

Numerical and Physical Modelling of Aerated Skimming Flows over Stepped Spillways [PDF]
, 2019 Stepped spillways are commonly used to control overflows from reservoirs, as they dissipate significantly more energy than smooth spillways. At high discharges, skimming flow occurs over stepped spillways, in which significant air entrainment occurs ...

Comparison of chute aerator effect on stepped and smooth spillways
, 2022 Bottom chute aerators are installed to prevent cavitation damages and they have been studied in detail on smooth spillways. In parallel, stepped spillways became widespread in the past decades.
