The design of an ogee spillway involves creating an S-shaped profile that matches the natural trajectory of a falling water jet to maximize discharge efficiency . Using a spreadsheet like Ogee Spillway Design.xls
Structural Stability: The smooth curve minimizes turbulence and vibrations, making it ideal for concrete gravity, arch, and buttress dams. ogee spillway designxls better
Excel Setup:
But for the hydraulic design of the crest profile itself? An XLS is faster, more transparent, and less error-prone than black-box software. The design of an ogee spillway involves creating
Using an XLS tool for Ogee design is generally "better" than manual calculations but has specific trade-offs compared to 3D modeling software. Unit toggles (SI or Imperial)
The best test of your XLS is simple: Plot the USACE (U.S. Army Corps of Engineers) standard crest profile as a scatter plot over your calculated curve. If they don’t overlap perfectly within 2mm (scaled), your coefficients are wrong.
