3This appendix present the images used to assess the model
4sensitivities described in
5Section~\ref{sec:sensitivity}.

10\caption{Results from reference model as reported in Section
11\protect \ref{sec:results},
12  i.e.\ including buildings and a friction value of 0.01.
13  The seaward boundary condition is as
14  provided by the \textsc{ursga} model. The left image shows the maximum
15  modelled depth while the right hand image shows the maximum modelled
16  flow velocities.}

24\caption{Model results for different values of Manning's friction
25  coefficient shown to assess sensitivities.
26  The reference inundation extent for a
27  friction value of 0.01 is shown in Figure
28  \protect \ref{fig:reference_model} (left).  The left and right images
29  show the inundation results for friction values of 0.0003 and
30  0.03 respectively. The inundation extent increases for the lower
31  friction value while the higher slows the flow and decreases the
32  inundation extent. Ideally, friction should vary across the entire
33  domain depending on terrain and vegetation, but this is beyond the
34  scope of this study.}

60  The reference inundation extent is shown in Figure

62  show the inundation results if the wave at the \textsc{anuga} boundary
63  is reduced or increased by 10 cm respectively. The inundation
64  severity varies in proportion to the boundary waveheight, but the
65  model results are only slightly sensitive to this parameter for the
66  range of values tested.}

90  The left hand image shows the inundation extent as modelled in the reference
91  model (Figure \protect \ref{fig:reference_model}) which includes
92  buildings in the elevation data. The right hand image
93  shows the result for a bare-earth model i.e. entirely without buildings. 
94  As expected, the absence of
95  buildings will increase the inundation extent beyond what was
96  surveyed.}
