I am trying to reproduce a model from an older HydroCAD (v7.10) report. The box culvert listings only have one dimension. Anyone know if this is width or height? It seems I will still need to guess the other dimension.
I visited the site over the weekend and measured the pipes. What was installed were round RCP pipes.
Oddly enough, when I revised the current HydroCAD model to round pipes, the flows match exactly with the old report for all storms. (they did not as square pipes)
OK, that makes more sense. I would expect an actual box pipe to report both width and height. I suspect the word "Box" in your report was manually entered as part of the device name or the inlet geometry, rather than being automatically generated by HydroCAD.
