\chapter{OlaFlow}
\section{2D Model}
A 2Dv model was built on a small domain around the breakwater (\SI{250}{\m}
from the crest).
A tool that allows mapping the output fields from swash to the initial fields
in olaFlow was built (currently only water level / alpha.water works).
Additional work is needed for the boundaries of the domain.

\chapter{SWASH model}
\section{1D model}
In order to find out if the reflection induced by the breakwater has an
influence on the sea state at the buoy's location, a one-dimensional model of
the zone between the buoy and the breakwater was created.
The considered domain is \SI{1450}{\m} long, with \SI{1250}{\m} between the
buoy and the breakwater, and a further \SI{200}{\m} offshore of the buoy.
The model is a 10 layers swash model accounting for porous media in near the
breakwater. The model was adapted from PA Poncet.
\subsection{Model 1}
A first run was produced in order to test the model with a water level of
\SI{0.5}{\m} using the measured spectrum from 2017-02-28 as the offshore
boundary condition and a sommerfeld radiation condition on the breakwater
boundary. The model was run over a duration of 30 minutes.
The reflection coefficient at the buoy's location was computed using
a PUV method \parencite{huntley1999use}.
The results are displayed in \autoref{fig:swash_1_R}.
\subsection{Model 2}
An attempt at running the model with the correct water level (\SI{4.5}{\m}) was
made without success, as the model does not seem to be able to compute
overtopping. Changing the boundary condition at the breakwater does not fix the
issue, and the model is not able to run with water on both sides of the
breakwater as the initial condition.
