     131This section details a range of comparisons at
     132virtual ``gauge'' points located
    132133within the study area, including the boundary. Note, these gauges are
    133134constructed for computational purposes only and are not physical tide

    135136any relationships between the bathymetric topography and the ``matching''
    136137of the ANUGA and MOST outputs. The difficult question is to
    137 how to define this matching. Further, are we concerned with the matching
    138 MOST and ANUGA in deeper water, or are we concerned
    139 with the impact difference ashore? Section \ref{sec:mostanugaonslow} deals
    140 with the first
     138how to define this matching. In this report, we will investigate
     139the comparison between MOST and ANUGA to determine the point of divergence.
     140Secondly, we are also interested in the difference in impact ashore
     141when the boundary is placed at 100m and 50m contour lines.
     142Section \ref{sec:mostanugaonslow} deals with the first
    141143issue with Section \ref{sec:compare50100onslow} dealing with the second.

     146Firstly, at what water depth should we place the ANUGA boundary? Where
    145147is the transition from deep water to shallow water? Some have
    146148suggested this can be determined
    147 by the ratio of the water's depth to the wavelength of the wave. In particular,
     149by the ratio of the water's depth to the wavelength of the wave.
     150In particular,
    148151when the depth of the water,
    149152$d$, becomes less than one half of the wavelength of the wave,

     176We want to compare MOST and ANUGA all the way to the shore - as
     177close as practical anyway. It is important to note here
     178that MOST and ANUGA are using different bathymetry data sets. MOST
     179typically uses a much coarser grid than ANUGA. We interpolate
     180both MOST and ANUGA output onto the defined point locations.

    193 Here, whilst it is not reasonable to compare MOST and ANUGA

    195 briefly examine the time series for the point locations
