Once the XLS tool calculates your ogee profile coordinates, you must transfer them to a drafting environment to create structural blueprints. To AutoCAD / Civil 3D:

(San Diego State University). This web‑based tool computes spillway rating curves. You input the spillway length, design head, approach velocity (optional), dam height, freeboard, and crest elevation. The output gives a table of elevation, head, discharge coefficient, and flow rate. No installation is required—it runs entirely in your browser.

Ensure the spillway is properly ventilated to maintain atmospheric pressure below the nappe, especially at lower heads. Hdcap H sub d Hmaxcap H sub m a x end-sub : The ogee is designed for a specific design head ( Hdcap H sub d What do you need to follow (e

However, designing an Ogee spillway manually involves solving tedious equations: the U.S. Army Corps of Engineers’ crested spillway profiles, upstream/downstream tangent adjustments, and discharge coefficient iterations. Share public link (San Diego State University)

Excel is widely used in civil engineering for several reasons: most engineers have Excel installed; the formulas are visible and verifiable (no “black box”); the iterative design loop can be implemented with simple circular references or manual iteration; and the output (coordinates, rating table) can be directly imported into CAD software. This transparency and accessibility make for ogee spillway design outside of large commercial packages.
