An ogee spillway is a commonly used hydraulic structure for safely conveying excess water from a reservoir or dam to the downstream channel without causing overtopping or structural damage. Its profile, characterized by a smooth, curved crest resembling an “S”-shape when viewed in section, is shaped to match the lower nappe of a free-flowing jet of water. This matching reduces flow separation and energy losses, producing a more efficient and stable overflow condition.
