+\section{Reflection coefficient verification}
+
+A small Python script has been written to generate theoretical wave height and homogenized velocity for a combination of
+incident and reflected waves.
+
+The method was taken from \parencite{huntley1999use}. Incident waves are modelled by white noise, reflected waves are
+incident waves shifted and multiplied by the reflection coefficient. Water level is the sum of incident waves and
+reflected waves, velocity is the difference of reflected waves and incident waves. Additionnal noise is added to the
+water level and velocity.
+
+Results are displayed in \autoref{fig:r_test}.
