Box Culvert Design Excel Sheet !new! 〈CERTIFIED〉

Your Excel sheet should include a check for inlet control vs. outlet control using FHWA nomographs converted into lookup tables (VLOOKUP). Iterate using Excel’s Goal Seek to find the minimal span/rise that passes Q without exceeding headwater limits.

Using Excel’s built-in functions like GOAL SEEK or iterative circular references, the engineer can quickly determine the required height and width of the culvert barrel. The sheet can automatically compute flow velocities, Froude numbers, and headwater elevations. Drop-down menus can select between different inlet edge conditions (e.g., square-edge, rounded) with corresponding coefficients stored in a lookup table. This allows the designer to test multiple scenarios—changing barrel sizes or slopes—in seconds, ensuring the hydraulic performance meets regulatory requirements before any structural calculation begins.
