 r5667 were used, with each test being repeated once. 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. A variety of measurements were taken during the simulation.  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. The wave profile was video recorded, this determined the location of breaking waves. All the tests produced 4 to 7 waves.  Generally the first wave did not break, with subsequent waves breaking; accept for T2R1 and T2R2, for which the first 3 waves did not break. Details of the tests performed are given in Table \ref{tab:hinwoodSummary}. 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 T1R1 & 3.5 & 400 & 0.200 \\ \hline T1R2 & 3.5 & 400 & 0.200 \\ \hline T2R1 & 3.5 & 400 & 0.125 \\ \hline T2R2 & 3.5 & 400 & 0.125 \\ \hline T3R1 & 1.5 & 336 & 0.200 \\ \hline T3R2 & 1.5 & 336 & 0.200 \\ \hline T4R1 & 1.5 & 336 & 0.125 \\ \hline T4R2 & 1.5 & 336 & 0.125 \\ \hline % Mapping of new names to old names % T1R2 T1R3 % T1R1  T1R5 % T2R1  T2R7 % T2R2   T2R8 % T3R2  T3R28 % T3R1    T3R29 % T4R2  T4R31 % T4R1  T4R32 \end{tabular} as boundary conditions for the ANUGA simulations.  For both the experimental and simulation results the zero data was the still water line.  To quantify the difference between the simulated stage and the experimental stage the Root Mean Square Deviation (RMSD) (\cite{Kobayshi2000}) was used line.  A Manning's friction coefficient of zero was used.  To quantify the difference between the simulated stage and the experimental stage the Root Mean Square Deviation (RMSD) (\cite{Kobayshi2000}) was used $RMSD =\sqrt {\frac{1 }{n} \displaystyle\sum_{i=1}^{n}{(x_i - y_i)}^2}$ Figures \ref{fig:} to \ref{fig:} show the RMSD of each sensor and the location where each wave broke.
