This package provides a Python implementation of the HYDRUS-1D unsaturated zone model developed by Šimůnek, J., M. Th. van Genuchten, and M. Šejna. More information on the HYDRUS-1D model is available here. This software is licenced under the GNU GENERAL PUBLIC LICENSE found here. The Phydrus code is developed by R.A. Collenteur and M. Vremec. With Phydrus, a HYDRUS-1D model can be created, calibrated and visualized through Python scripts, making it easy to adjust the model and providing a 100% reproducible workflow of your modeling process.

Examples of using Phydrus can be found in the example folder. This folder also contains a number of Jupyter Notebooks that thoroughly explain the use of the software. Documentation is hosted on ReadTheDocs: https://phydrus.readthedocs.io.

Phydrus is in active development, and bug reports are welcome as GitHub Issues. General questions or discussions are possible through GitHub Discussions

The Phydrus package is available from the Pypi package index and can be installed as follows:

>>> pip install phydrus

To install in developer mode, use the following syntax:

>>> pip install -e .

Before you can use Phydrus the adapted Fortran77 files need to be compiled to an executable. Phydrus-optimized Fortran Hydrus-1D code is available from a dedicated repository. Detailed instructions on how to compile the Fortran code can be found on the Documentation website.

Phydrus is a community effort and help is always welcome. If you have found a bug, please open a GitHub issue to report it. Pull requests including bug fixes and new functionality are very welcome and will be accepted on the Dev-branch of this repository.

If you use phydrus for one of your projects, we ask that you cite the code as follows: Collenteur, R.A., Brunetti, G., and M. Vremec (2019) Phydrus: Python implementation of the HYDRUS-1D unsaturated zone model. Version X.X.X
