Enter your specific project parameters, such as design head ( Hdcap H sub d ), crest length ( ), and approach velocity. 📐 Typical Mathematical Profile of an Ogee Spillway
If you are building your own spreadsheet or verifying the outputs of a downloaded .xls file, follow these major steps: 1. Determine Design Discharge Calculate the peak flood discharge ( ) that the spillway must safely pass. Establish the maximum reservoir water level. 2. Calculate Crest Length ogee spillway designxls install

and HEC‑HMS – While these are full hydraulic modeling packages, they are often used in conjunction with spreadsheet pre‑design. As described in a US Bureau of Reclamation case study, initial spreadsheet calculations size the ogee weir; those dimensions are then verified in HEC‑HMS and HEC‑RAS simulations.
Since these tools are document files rather than standalone software, the setup process is straightforward: 1. Download the File
Use the tool inside your 3D modeling software to import the file and generate a 3D solid model of the spillway overflow section.
