- np=integer [required]
- Number of processors to use (>= 3)
- threshold=float
- Threshold water-surface elevation change to conclude calculation
- Default: 0.001
- h_runoff=float
- Initial depth of uniform runoff [thickness in map units]
- h_runoff_raster=name

- Name for output raster map
- water=name
- Output water depth at the end of the run
- Name for output raster map
r.flowfill runs the FlowFill code (Callaghan and Wickert, 2019) that moves water cell-by-cell to flood depressions in a DEM. It can be used as a simplified/cellular simulation of downslope flow (though not equivalent to physics-based approaches for flow) or as a tool to fill depressions in a DEM.
