Hi Everyone

Hope this email find you safe and healthy

I tried watershed delineation with both ArcGIS and GRASS. but I got different results.

I was using D8 flow direction method in both ArcGIS and GRASS. My study area is very flat. Is there any tool in GRASS will generate the same result with ArcGIS

Thanks
