I'm using QGIS 3.0.0 and I've created a model to delineate a watershed. The model has 3 steps:
- Merge 4 SRTM tiles
r.watershedon the merged tiles
r.water.outleton the flow direction output from step 2. This part also uses a string input representing the outlet position (x,y)
The first 2 steps (merge and
r.watershed) run fine. But
r.water.outlet complains that it could not find the input raster (flow direction). I noticed that between the two GRASS algorithm, a new grass section is being initialized. Could this cause QGIS not to find the input raster?
Log from the model run can be found here
