 r5641 2D models for run-up simulations of this type. Once results are availble, need to compare to Hubbard and Dodd and draw any conclusions from nested rectangular grid vs unstructured gird. Figure \ref{fig:circular screenshots} shows a sequence of screenshots depicting the evolution of the solitary wave as it hits the circular island.

The wave generator can generate waves up to 0.6m in height, with a period range of 0.3 - 7.0 seconds. Four tests with different combinations of wave height and wave period were used. Two repititions were of each test were made. A variety of measurements were taken during the simulation.  The wave height at breaking, when present, were measured using a video recorder. Mid-depth water velocity and wave height were measured on the approach section.  The water height at several points along the flume were measured using pressure transducers. Details of the tests performed are given in Table \ref{tab:hinwood test summary}. \begin{table} \caption{Details of the Monash University experiments.} % Can't get right \begin{center} \begin{tabular}{ c   p{3cm}  p{3cm}   p{3cm}  } \hline Test Name & Beach slope nominal, \emph{degrees}   & Water depth offshore, \emph{mm } & Wave frequency nominal, \emph{Hz}  \\ \hline T1R3 & 3.5 & 400 & 0.200 \\ \hline T1R5 & 3.5 & 400 & 0.200 \\ \hline T2R7 & 3.5 & 400 & 0.125 \\ \hline T2R8 & 3.5 & 400 & 0.125 \\ \hline T3R28 & 1.5 & 336 & 0.200 \\ \hline T3R29 & 1.5 & 336 & 0.200 \\ \hline T4R31 & 1.5 & 336 & 0.125 \\ \hline T4R32 & 1.5 & 336 & 0.125 \\ \hline \end{tabular} \label{tab:hinwood test summary} \end{center} \end{table} \label{sec:friction} \clearpage
