[upd] | Ogee Spillway Designxls Better

A 50-line Python script using numpy and scipy.optimize can solve the complete ogee profile, including the elliptical upstream quadrant, to micro-inch precision. It can then export the cut/fill coordinates directly to a CAD file (DXF). No VBA crashes. No manual file management.

Since I cannot attach an .xlsx file directly, I will provide a comprehensive and the exact Formulas/Logic you need to build a professional-grade spreadsheet. This guide transforms a basic calculator into an engineering tool. ogee spillway designxls better

x to the 1.85 power equals 2.0 center dot cap H sub d to the 0.85 power center dot y Spreadsheets like the Ogee Spillway Profile Spreadsheet automate this coordinate generation. Determine the Tangent Point A 50-line Python script using numpy and scipy

Better spreadsheets provide coordinates for the downstream profile (often following the USBR or WES standard shapes) to prevent sub-atmospheric pressure and cavitation. No manual file management

The following steps are typically automated in high-quality design spreadsheets: Determine Initial Design Head ( cap H sub e Assuming an initial discharge coefficient ( ) and using the net crest length ( ), calculate a trial cap H sub e using the formula Calculate Effective Crest Length ( cap L sub e Adjust the net length for pier and abutment contractions:
