Physical and Numerical Comparison of Flow Over Ogee Spillway in the Presence of Tailwater
Journal of Hydraulic Engineering, 2006 Data obtained from two physical models were compared to the results obtained from numerical model investigations of two ogee-crested spillways. In 2001, Savage and Johnson investigated ogee-crested spillways without the effect of tailwater; the present ...

Numerical and experimental models applied to an ogee crest spillway and roller bucket stilling basin
RBRH, 2020 Traditionally, reduced physical models are used to allow control, instrumentation and experimental evaluation of flow. More recently, computational fluid dynamics (CFD) has emerged as a tool that allows numerical modeling of flows and can complement the ...

The hydraulics of flow on stepped ogee-profile spillways.
, 1997 Because of its simple form, its effectiveness as an energy dissipator, and its contribution to dam stability, the stepped spillway is one of the oldest drop structure used in the construction of small dams.

Discharge coefficients for ogee spillways
Water Supply, 2022 Abstract Discharge over an ogee weir is related to the length of the weir, upstream total head above the weir crest and the discharge coefficient. The discharge coefficient is influenced by several factors; in this study, some parameters that influence discharge coefficients of ogee weirs are investigated. These factors include: the weir

Investigation of turbulent flows using spillway models aiming to aid downstream migration of fish
River Research and Applications, Volume 39, Issue 6, Page 1110-1121, July 2023., 2023 Abstract Dams and other flow control structures constitute obstacles to upstream and downstream aquatic habitats, reducing life‐cycle success and even eliminating diadromous and potamodromous fish species from river basins. Providing effective passage past hydroelectric dams is critical for restoring habitat connectivity and sustaining populations of ...
