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 ...

History of Stepped Channels and Spillways: a Rediscovery of the 'Wheel' [PDF]
Canadian Journal of Civil Engineering, 1995 Recently, spillways with a stepped profile have regained interest and favor among design engineers to pass flood waters over the dams. The stepped geometry enhances the energy dissipation above the spillway and reduces the size of a downstream stilling ...

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 Hydraulics of Stepped Chutes and Spillways [PDF]
, 2002 The stepped channel design have been used for more than 3,500 years (chapter 2). A significant number of dams were built with overflow stepped spillways during the 19th century and early 20th century, before the design technique became outdated with the ...

Hydraulics of Stepped Spillways and Cascades [PDF]
, 1994 Stepped spillways have become a popular method for handling flood releases. The steps increase significantly the rate of energy dissipation taking place on the spillway face and reduce the size of the required downstream energy dissipation basin.
