HexWatershed: a mesh independent flow direction model for hydrologic models.


This Python package provides a <a href="http://www.python.org">`Python`</a> 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.
