- dem_modflow=name
- Hydrologically corrected DEM at MODFLOW grid resolution
- Name for output raster map
r.gsflow.hydrodem generates a hydrologically-correct MODFLOW DEM for GSFLOW based on higher-resolution flow routing. It does so by taking minimum grid cell elevations where streams are present, and mean grid cell elevations elsewhere, while coarsening the resolution to that of the specified MODFLOW grid resolution.
