Hi all
I would like to generate watersheds for an area using the tools in spatial analyst. The area is situated in a city where there is a stormwater network that will influence on the catchment areas.
Would it be correct to use the raster calculator to combine the DEM with the storm water pipes? Or should you solved this in another way?
