-The results from the large scale SWASH model using raw buoy measurements as a boundary conditions will be used in order
-to feed the small scale Olaflow model. Wave transformation is studied from the buoy to the breakwater. Those results
-show that the amplitude of the identified wave gets lower as the wave propagates over the domain. Nevertheless, a long
-trough precedes the crest, with a zone reaching 400m long where the water level is below 1m is present in front of the
-wave crest.
+The free surface obtained with the SWASH model using raw buoy measurements as an elevation boundary condition is
+plotted in Figure~\ref{fig:swash_trans}. Those results display a strong transformation of the wave between the buoy and
+the breakwater. Not only the amplitude, but also the shape of the wave are strongly impacted by the propagation over
+the domain. While the amplitude of the wave is reduced as the wave propagates shorewards, the length of the trough and
+the crest increases, with a zone reaching 400m long in front of the wave where the water level is below 0m.
