My attempt to list interesting open source python projects that can be used in the field of Hydrology. Suggestions as issues or pull requests are welcome!
UPDATE: The Pypa package authority has now added "Hydrology" as a classifier so we can start collecting python packages used by the hydrological community! If you are maintaining a python package, please add Topic :: Scientific/Engineering :: Hydrology to your setup.py so people can find your package.
