However, initial comparisons between the deep water 18 model MOST (Method of 17 study area (from 6300 km$^2 for Onslow to 24400 km$^2 for Pt Hedland) 18 then increases the number of triangles, thereby increasing 19 the computational time. It would be possible to increase the cell resolution 20 to minimise the number of triangles, however, the cell resolution would have 21 to be raised to an unacceptable level. 22 However, initial comparisons between the deep water model MOST (Method of 19 23 Splitting Tsunami) and ANUGA show that they are reasonably well matched 20 24 to the 50m contour line.
