%description
Seamless extraction of river networks from digital elevation models data.
The package allows analysis of digital elevation models that can be either
externally provided or downloaded from open source repositories (thus
interfacing with the 'elevatr' package). Extraction is performed via the
'D8' flow direction algorithm of TauDEM (Terrain Analysis Using Digital
Elevation Models), thus interfacing with the 'traudem' package. Resulting
river networks are compatible with functions from the 'OCNet' package. See
Carraro (2023) <doi:10.5194/hess-27-3733-2023> for a presentation of the
package.
