Ogee-Crested Weirs
From ASDSO Dam Safety Toolbox
“An additional type of weir is the ogee. The downstream section of an ogee crest is parabolic shaped to mimic the underneath side of the nappe jet passing over a sharp-crested weir. Ogee weirs are commonly found in large hydraulic structures where passing the design flow at minimum head is important. For more information on ogee crests, see U.S. Department of Interior Bureau of Reclamation, Design of Small Dams."[1]
