*HydPy* is an interactive framework for developing and applying different types of
hydrological models, originally developed for specific research purposes at the
`Ruhr-University Bochum`_.  Later, it was extended on behalf of the `German Federal
Institute of Hydrology`_ in order to apply it in practical applications like runoff
forecasting in large river basins.  Now, it is being maintained by `Björnsen Consulting
Engineers`_.


*HydPy* is intended to be a modern open-source software based on the programming
language `Python`_, commonly used in many scientific fields.  By using different
well-established `Python`_ libraries and design principles, we target high standards of
quality and transparency. To avoid writing model cores in a more native programming
language, *HydPy* includes a `Cython`_-based automatism to translate Python code to C
code and to compile it, which results in high computational efficiency.  It also offers
a multi-threading mode, which speeds up simulations even more by utilising a freely
selectable number of CPUs in parallel.

*HydPy* has no graphical user interface (so far). Instead, it is thought to be applied
by executing Python scripts. These scripts help to increase the reproducibility of
studies performed with *HydPy* because they can be easily shared and repeatedly
executed.  This approach facilitates discussing possible weaknesses of *HydPy* and its
implemented models and comparing different methodical approaches (e. g. different
strategies to calibrate model parameters).  However, if you are not an experienced
hydrologist with basic programming skills, you may need some help to become acquainted
with *HydPy*.

We host *HydPy* in a `GitHub repository`_ and everyone is allowed to download, modify,
and use it.  However, when passing the (possibly modified) code to third parties, you
have to be aware you cannot change the selected `GNU Lesser General Public License 3`_
to a "less open source" license.  If you, for example, implement a model into *HydPy*,
you can be sure that all possible further developments of your model code are still open
source and the mentioned third parties are allowed to pass this modified source code to
you.

*HydPy* offers many functionalities to make the implemented models as transparent and
reliable as possible.  For this reason, the `online documentation`_ is automatically
updated for each new *HydPy* version and includes different `documentation test`_
mechanisms, ensuring that *HydPy* is working as expected and that the complete
documentation is up-to-date.
