Original simulations (March 2011)

Inundation maps

These maps were generated directly from the results of the refined simulation. The spatial resolution in flooded areas is automatically adapted down to ~500 m. Note that the topography is defined using the ETOPO-1 data (1 arcminute i.e. ~1.8 km). The results below could be improved using higher-resolution topographic data (e.g. STRM).

In all Gerris results, the colorscale encodes the log of the maximum wave elevation reached over 5 hours.
