This article explores how to create or identify a superior ogee spillway design spreadsheet, covering crucial hydraulic calculations, profile generation, and optimization tips.

Design equations and coefficients

To map an ogee profile downstream of the crest, engineers generally use empirical equations established by organizations like the United States Bureau of Reclamation (USBR) or the U.S. Army Corps of Engineers (WES). A standard downstream profile equation takes the form:

— When generating coordinates, ensure that upstream and downstream curve segments meet with continuous slope. Small arithmetic errors can produce hydraulic discontinuities that affect performance.
