The second approach is more inclusive and that is to apply the Breach Depressions tool to the DEM. The Whitebox approach is called something like Breach Depressions and is outlined below and fully explained here. How is ArcGIS supposed to know from a DEM that pipes run underground? Whitebox has developed a tool that will fix this issue and I demonstrate an ArcGIS solution at this location Account for bridge overpasses in a ground DEM to allow for water flow under the overpass.Įssentially the ArcGIS approach involves having a file of the underground "passes" and burning these into the DEM. Yes it will mess things up completely but this is not an ArcGIS issue.
