Numerical simulation of coastal flood made by Joanna storm (France, 2008)

Participant : Fabien Marche.

In collaboration with BRGM, a numerical platform based on Fabien Marche's numerical too WaveBox was developed in order to simulate coastal urban submersions associated with intense storms, see [22] . A nudging strategy is implemented with:

• a barotropic model at the regional scale,

• a spectral wave model with embeded meshes accounting for water level evolution and output from the large scale model,

• a free surface Shallow Water model (SURF2D, now called WaveBox) used at very high resolution for the submersion process.
