Ogee — Spillway Designxls Install
In the world of hydraulic engineering, an ogee spillway is the gold standard for safely discharging floodwaters. Its distinctive S-shaped profile isn't just for show—it is meticulously designed to match the natural curve of falling water, ensuring maximum efficiency and preventing structural damage.
The Ogee (S-shape) profile is the gold standard for spillways because it mimics the underside of a nappe flowing over a sharp-crested weir. This shape minimizes sub-atmospheric pressure, prevents cavitation, and maximizes discharge efficiency. What this Excel tool handles for you: Automated Profile Generation: Instantly calculate coordinates based on your design head ( cap H sub d Discharge Calibration: Quickly determine the flow rate ( ) for various head levels.
