+\subsection{Buoy spectrum}
+
+The swash model was run over 4 hours with the spectrum obtained from the buoy, with and without the breakwater. (2
+layers).
+
+A zero-crossing methods was implemented to find the largest waves.

 %\subsection{2D Model}
 %Working on 2D model which might work with overtopping.
