SWASHES: Shallow Water Analytic Solutions for Hydraulic and Environmental Studies.<\/span><\/h3>\n

SWASHES is a library of Shallow Water Analytic Solutions for Hydraulic and Environmental Studies.
A significant number of analytic solutions to the Shallow Water equations is described in a unified formalism. They encompass a wide variety of flow conditions (supercritical, subcritical, shock, etc.), in 1 or 2 space dimensions, with or without rain and soil friction, for transitory flow or steady state.
The goal of this code is to help users of Shallow Water based models to easily find an adaptable benchmark library to validate numerical methods.<\/p>\n

The SWASHES software can be downloaded on the website sourcesup<\/a>.
This software is distributed under CeCILL-V2<\/a> (GPL compatible) free software license. So, you are authorized to use the Software, without any limitation as to its fields of application.
For any question, contact us at: swashes.contact@listes.univ-orleans.fr <\/a> (F. Darboux, O. Delestre, C. Lucas).<\/p>\n

For Python<\/b> enthusiasts, L. Courty<\/a> developed several packages.
\nIf you are using the Conda package manager, the SWASHES package is available at anaconda.org\/conda-forge\/swashes<\/a>. It works for Linux, Windows and MacOS.
\nIf you are more familiar with PyPI, you can also install SWASHES for Linux, Windows and MacOS, see pypi.org\/project\/swashes\/<\/a>.
\nNote that a Python API has also been developed: pyswashes. With it you can obtain the selected analytic solution in the form of a csv, Pandas dataframe, NumPy array or ASCII Grid format. See pyswashes.readthedocs.io\/en\/latest\/<\/a>.<\/p>\n\n
