In this paper, we first use a one-dimensionnal depth-averaged non-linear non-hydrostatic model to verify that the
signal measured by the wave buoy can be used as an incident wave input for the determination of hydrodynamic conditions
near the breakwater. For this model, we use a SWASH model \parencite{zijlema2011} already calibrated by
\textcite{poncet2022} on a domain reaching 1450m offshore of the breakwater.

Then, we use a nested VOF model in two vertical dimensions that uses the output from the larger scale SWASH model as
initial and boundary conditions to obtain the hydrodynamic conditions on the breakwater. The models uses olaFlow

during the passage of the identified wave. The results displayed in Figure~\ref{fig:U} show that the flow velocity
reaches a maximum of 14.5m/s towards the breakwater during the identified extreme wave. The maximum reached velocity is
similar to earlier shorter waves (at t=100s and t=120s), but the flow velocity remains high for twice as long as during
those earlier waves. The tail of the identified wave also exhibits a water level over 5m for over 40s.
