Ogee Spillway is a high-efficiency overflow structure characterized by an "S-shaped" profile that follows the trajectory of a free-falling water jet. This specialized design prevents vacuum formation and cavitation by ensuring the water remains in constant contact with the surface. Ogee Spillway Design Principles
: Constants depending on the upstream face slope and the velocity of approach. For a vertical upstream face, standard values are often 2.2 Functional Components ogee spillway designxls install
