    33at which the output from MOST is the input to ANUGA is

     4sufficient at between the 50m and 100m bathymetric contour line.
     5In constrast to the Onslow study,
     6we choose the 50m contour line as the seaward boundary due primarily
     7to computational constraints.

    59Preliminary investigations indicate that MOST and ANUGA compare
    6 well at the 100m contour line. In addition, the resolution for

    812tsunamis with a wavelength of 20-30km, and the wavelength of

    1216of the order of 10m and we would expect that a tsunami wave
