Save the validated template as “Ogee_Spillway_Design_Template_v1.xlsm” (using the macro‑enabled format if you wish to add VBA automation for the iteration). Keep backups of the master file to avoid corruption.
For the design head, the coefficient is taken as the maximum value (typically ≈2.20). At other heads, a correction factor C/C d is applied, a relationship that is usually presented as a curve or a lookup table.
The spreadsheet references built-in design curves to adjust the ideal discharge coefficient based on the ratio of the dam height to design head ( ). For a high standard ogee crest, C0cap C sub 0 typically approaches (SI units) or (English units). Phase 3: Generating Coordinate Geometry ogee spillway designxls install
If the sheet uses automated calculation buttons or custom functions, a yellow message bar will appear: "Security Warning: Macros have been disabled."

An Ogee spillway consists of three main zones:
The (often referred to as “ogee spillway designxls”) is an indispensable tool for modern hydraulic engineers. It automates the iterative calculations, generates precise profile coordinates, and produces a complete rating table—all within a transparent, auditable Excel environment. There is no single “installer” to download; instead, the engineer either builds the template from the formulas presented in this article or adapts an example template from a reliable academic source. At other heads, a correction factor C/C d
An ogee spillway is a type of controlled spillway that uses a curved, S-shaped profile to dissipate excess energy and reduce the risk of erosion downstream. The ogee shape allows for a smooth, gradual transition from the dam to the downstream channel, minimizing turbulence and promoting stable flow. Ogee spillways are widely used in dam construction due to their effectiveness in managing floodwaters and preventing damage to the dam and surrounding infrastructure.
