I have created these raster files for a river basin:
DEM Flow Direction Flow Accumulation
I need the values for the distances from each spring to the outlet along the flow path length. By now I used Qgis 2.16.1 with Grass and Saga tools. Moreover I figured out that maybe the r.stream.distance command is what I need, but it isn´t available in the toobox and i couldn´t add it. I am a newcomer and happy about any explanation.
