The spreadsheet uses these parameters to calculate:

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. Pressure Analysis:

The standard weir equation gives the discharge capacity: ogee spillway designxls install

Complete Guide to Ogee Spillway Design XLS: Installation, Setup, and Engineering Principles

While a dedicated “ogee spillway designxls” executable file is not distributed as a standard software package, several spreadsheet‑based and online tools are available that perform the same functions. They fall into two categories: and online calculators . The spreadsheet uses these parameters to calculate: The

: Verify that the downstream power curve transitions seamlessly into the straight slope of the spillway glacis without any abrupt geometric breaks. ✅ Summary of Ogee Spillway Design Steps

If the spillway height ( P ) above the streambed is greater than 1.33· Hₑ , the influence of approach velocity on the discharge coefficient is negligible, and Hₑ can be used directly. If not, the velocity head Vₐ²/(2g) must be added to the static head. Pressure Analysis: The standard weir equation gives the

Elias began entering the project's critical parameters into the spreadsheet. The tool was built around the USBR (U.S. Bureau of Reclamation) standards. He typed in: Design Head ( cap H sub d 10 metres. Spillway Height ( 100 metres above the river bed. Discharge ( Step 2: The Calculation

The values of K and n are tabulated only for specific upstream slopes. If the slope does not exactly match one of the four cases, interpolation may be required, but many engineers simply choose the closest one.
