HexWatershed
HexWatershed: a mesh independent flow direction model for hydrologic models.
This is the C++ backend of the HexWatershed Python package (https://github.com/changliao1025/pyhexwatershed).
The HexWatershed Version v1.0 has been moved under the PNNL Github account at: https://github.com/pnnl/hexwatershed
Currently, only HexWatershed v3.0 is maintained and supported.
