Using sequent depth equations, the tool calculates basin length, end sill height, and apron elevation.
In the world of dam engineering, few structures are as critical—or as mathematically elegant—as the . Named for its distinctive S-shaped curve that mimics the profile of a falling nappe (water jet) over a sharp-crested weir, the Ogee spillway is the gold standard for gravity dam overflow sections. However, designing one requires solving complex hydraulic equations, iterating over discharge coefficients, and checking multiple failure modes. Ogee Spillway Design.xls
Ogee Spillway Design (.xls) spreadsheet is a technical tool used by hydraulic engineers to calculate the precise S-shaped profile and discharge capacity of a dam spillway. Its primary purpose is to model a crest shape that mimics the underside of a free-falling water jet, which minimizes sub-atmospheric pressure and prevents structural damage like cavitation. www.researchgate.net Core Informative Features (PDF) Ogee Spillway Profile: Spreadsheet - ResearchGate Using sequent depth equations, the tool calculates basin
Before diving into the spreadsheet mechanics, it’s vital to understand why this specific shape endures. iterating over discharge coefficients
Although not a full dam design tool, a good includes simplified stability checks for the overflow monolith:
