Different results compared to Esri ArcGIS computational workflow is caused by very different flow accumulation values:

  • Esri ArcGIS (range: 0 - 20741)
  • r.watershed -s (range: -34068 - 5697)
  • r.watershed -sa (1 - 34068)

To be tested:

  1. ArcGIS: Fill + Flow Accumulation
  2. GRASS GIS: r.hydrodem + r.watershed

Major question: what is correct?
