I'm trying to delineate several watersheds within a very large basin. All of the watersheds drain to a highway and I'd like to generate hydrographs for each of them. When starting a new project using the HECGeoHMS extension and adding an outlet, do I have to generate the project for that one outlet before adding other outlets? Or can you give me some pointers on the best way to delineate multiple watersheds within a large basin?
I am running version 10.1 of ArcGIS and the corresponding HECGeoHMS extension.
Thanks!
