A mesh independent flow direction model for hydrologic models
Project description
HexWatershed
HexWatershed: a mesh independent flow direction model for hydrologic models`
This Python package provides a Python interface to the underlying HexWatershed model.
HexWatershed has been compiled and tested on various 64-bit Linux and Mac based platforms.
Quickstart
Ensure you have a c++ compiler and the cmake utility installed.
Clone/download + unpack this repository.
python3 setup.py build_external
python3 setup.py install
Note: installation of HexWatershed requires a c++ compiler and the cmake utility. Besides, the GDAL is required to build the model.
