r.hand: Height Above Nearest Drainage

[cwhite911]

The r.hand tool uses the HAND method to create flood inundation extent estimates. The tool will return an inundation raster map or a times series (STRDS) of inundation raster maps based on user define water levels.

I would like to reference whoever first came up with the GRASS GIS implementation for inundation using the HAND method. The earliest reference I'm aware of is https://grasswiki.osgeo.org/wiki/From_GRASS_GIS_novice_to_power_user_(workshop_at_FOSS4G_Boston_2017).

This relies on other addons, we don't have a good mechanism to handle that, but at least it should test if they are installed, something like:

grass-addons/src/raster/r.futures/r.futures.calib/r.futures.calib.py

I don't remember exactly how we came up with it, but maybe you can just cite the r.stream authors who implemented the actual algorithm.
