Flow Characteristics on the Ogee Spillway

Journal of the Hydraulics Division, 1957
General formula is suggested for calculation of spillway energy loss, and theoretical derivation is presented defining limit between true hydraulic jump and drowned jump; criterion for estimating bottom velocities along level spillway apron is considered.

Experimental and Numerical Modeling of the Gated and Ungated Ogee Spillway

2023
Spillways are hydraulic structures that allow dams to release and convey surplus water or flood from the reservoir to the downstream channel. The spillway is a safety structure that prevents the overtopping of the dam. Many dam failure disasters were due to the inadequate capacity of the spillway, which fully illustrates the prominence of spillway ...

Investigating impact of converging training walls of the ogee spillways on hydraulic performance

Paddy and Water Environment, 2020
Due to their economical and structural aspects, ogee-crested spillways can be constructed and operated in a wide variety of situations. In this study, a three-dimensional physical model (1:50 scale) was planned and constructed to investigate the impact of converging training walls of the ogee spillways with a curve axis on flow characteristics such as ...

The hydraulics of flow on stepped ogee-profile spillways.

2009
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. With the relatively recent introduction of Roller Compacted Concrete (RCC) and particularly (rockfill) gabions as dam construction materials, the ...

Application of a Mitered Ogee Crest to Steep Stair-Stepped Spillways

World Environmental and Water Resources Congress 2008, 2008
Design flow requirements for both new and existing dams have increased over the past 30 years due (in part) to a series of dam failures caused by embankment overtopping. Increased spillway design flow requirements often require the renovation and re-design of the spillway crest for increased discharge without increasing reservoir pool elevation ...
