Comparison and Validation of Two Parallelization Approaches of Fullswof_2D Software on a Real Case

Full SWOF_ 2D (Full Shallow Water equation for Overland Flow in 2 dimensions) is a free software designed for shallow water flow simulations. The shallow water equations are solved thanks to a well-balanced finite volume scheme (based on the hydrostatic reconstruction), which is adapted to the properties of the model considered (in particular conservative laws, hyperbolic system and steady states). The sources of this software (in C++) are available from https :// sourcesup. renater. fr/ projects/ fullswof-2D/. This software has been validated on several analytical test cases integrated in SWASHES library and on rainfall overland flow simulations. Because of simulation on big data necessity, this software has been parallelized with two different strategies (MPI and SKELGIS) in the framework of the CEMRACS 2012. The purpose here is to continue the comparison and the validation of these two versions of FullSWOF_ Paral on a realistic dam break test case : Malpasset's dam break.Delestre Olivier, Coullon Hélène, Abily Morgan, Cordier Florian, Gourbesville Philippe.
