Parameters:
- dem=name [required]
- Input higher-resolution elevation data
- Name of input raster map
- grid=name [required]
- MODFLOW grid
- Or data source for direct OGR access
- streams=name [required]
- Vector map of stream network (lines)
- Or data source for direct OGR access
- streams_modflow=name [required]
- Stream network at MODFLOW grid resolution
- Name for output raster map
- 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.
