In the world of dam design and hydraulic structures, few elements are as critical—or as mathematically complex—as the . Named for its characteristic "S" shape (ogee curve), this spillway type is the gold standard for concrete gravity dams because it efficiently passes floodwater with minimal energy loss. | | "Compile error: Can't find project or
The primary objective of the ogee shape is to achieve maximum hydraulic efficiency while maintaining structural stability. Hydraulic Efficiency
