    105105\subsection{Tsunami Inundation}
    106 When coupled with ANUGA, the utility of MOST diminishes as water depth decreases. IS THIS TRUE OF URS???. Consequently the open ocean boundary of the ANUGA simulation was chosen to roughly follow the ...m depth contour along the Coast of Thailand. The North-South extent of the computational domain was chosen to maximise the number of locations for which run-up depths were measured, whilst keeping the computational domain `small enough' to avoid excessively large computational time. The computational domain is shown in Figure \ref{fig:computational_domain}
     106The utility of the URSGA model decreases with water depth unless an intricate sequence of nested grids is employed. On the other hand, while the ANUGA model is less suitable for earth quake source modelling and large study areas, it is designed with detailed on-shore inundation in mind.
     107Consequently, the Geoscience Australia tsunami modelling methodology is based on a hybrid approach using models like URSGA (or the MOST model) for tsunami generation and propagation up to a 100m depth contour where the wave is picked up by ANUGA and propagated on shore using the finite-volume method on unstructured triangular meshes.

     109In this case the open ocean boundary of the ANUGA study area was chosen to roughly follow the 100m depth contour along the west coast of Phuket Island.
     110The other boundaries were chosen to maximise the number of locations for which run-up depths were measured, whilst keeping the computational domain `small enough' to avoid excessively large computational time. The computational domain is shown in Figure \ref{fig:computational_domain}
