Re: Median Drainage in StormCAD
Jesse Dringoli
Hello, StormCAD has a "ditch" inlet type, which it sounds like you should use in this case. You would enter the channel side slope, bottom width and grate size (in the catchbasin properties) and StormCAD would then compute the efficiency based on standard…
