Optimizing Ogee Spillway Design: Why Custom XLS Solutions Are Better Than Standard Methods

Formulas to calculate the invert radius of the flip bucket or toe curve at the bottom of the spillway to guide water into the stilling basin. ogee spillway designxls better

You pull out your copy of USBR’s Design of Small Dams or EM 1110-2-1603 , flip to the discharge coefficient tables, and start punching numbers into a generic Excel sheet. You spend hours debugging lookup tables for the upstream face slope, fiddling with unit conversions, and praying you didn’t mis-type the design head (H(_d)) relationship.

The upstream quadrant is typically defined by a series of compound curves or a smooth polynomial equation to prevent flow separation and localized pressure drops. The USBR defines this curve using specific elliptical or multi-radius arcs that interface smoothly with the vertical dam face. Step-by-Step Spreadsheet Architecture You spend hours debugging lookup tables for the

Modern spreadsheet solutions can go beyond numerical calculations. Some advanced worksheets integrate with tools like AutoCAD to plot the spillway's profile accurately. This allows for direct visual feedback, ensuring the designed curve is not just mathematically correct but also geometric feasible.

Mixing Metric (SI) and US Customary units will ruin hydraulic calculations. Solution: Dedicate your workbook strictly to one unit system, and use explicit text labels on every single cell. fiddling with unit conversions

You have three options:

The ogee profile is typically divided into two sections: upstream and downstream of the crest apex. : Usually follows a power law equation:
