SWASHES: Shallow Water Analytic Solutions for Hydraulic and Environmental Studies.

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.

The SWASHES software can be downloaded on the website sourcesup.
This software is distributed under CeCILL-V2 (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 (at) listes.univ-orleans.fr (F. Darboux, O. Delestre, C. Laguerre, C. Lucas).

Some examples (used in comparison with FullSWOF approximate solutions):
Transcritical flow with shock
Mac Donald's type solution with a smooth transition and a shock
Dam break on a dry domain without friction
Thacker's planar surface in a paraboloid
Mac Donald pseudo-2D supercritical solution
MacDonald pseudo-2d subcritical solution

For more details we refer to the documentation of the code.
