r7227 r7228 628 628 of this data comes uplifted or subsided coral heads. The length of 629 629 vector increases with the magnitude of the displacement, the length 630 corresponding to 1 m of observed motion is shown in the top right630 corresponding to 1 m of observed motion is shown in the top right 631 631 corner of the figure. As can be seen, the source model detailed in 632 632 Section~\ref{sec:modelGeneration} produces a crustal deformation that … … 767 767 %FIXME (Ole): Perhaps rephrase a bit as the 1cm vs 10cm is hard to 768 768 %understand. Remove figure using 1cm inundation 769 Maximum onshore inundation elevation was computed from the model throughout the entire Patong Bay 770 region. Figure~\ref{fig:inundationcomparison1cm} shows very good 771 agreement between the measured and simulated inundation. However these results are dependent on 772 the classification used to determine whether a region in in the numerical simulation was inundated. 773 In Figure~\ref{fig:inundationcomparison1cm} a point in the computational domain was deemed 774 inundated if at some point in time it was covered by at least 1cm of water. 775 However the precision of the field measurements is most likely different to the 1cm used 776 to determine the simulated inundation. The inundation boundary generated by the on-site survey 777 was determined by observing water marks and other signs left by the receding waters. Consequently 778 the measurement error along the inundation boundary of the survey varies significantly. However it is 779 impossible to quantify this error. Figure~\ref{fig:inundationcomparison1cm} shows the simulated 780 inundation using a threshold of 10cm. An inundation threshold of 10cm was selected for 781 the current and all future simulations to reflect the likely 782 accuracy of the survey and subsequently facilitate a more appropriate 783 comparison between the modelled and observed inundation area. 769 Maximum onshore inundation elevation was computed from the model 770 throughout the entire Patong Bay region. 771 Figure~\ref{fig:inundationcomparison1cm} (left) shows very good 772 agreement between the measured and simulated inundation. However 773 these results are dependent on the classification used to determine 774 whether a region in the numerical simulation was inundated. In 775 Figure~\ref{fig:inundationcomparison1cm} (left) a point in the computational 776 domain was deemed inundated if at some point in time it was covered by 777 at least 1 cm of water. However, the precision of the inundation boundary 778 generated by the on-site survey is most likely less than that as it 779 was determined by observing water marks and other signs 780 left by the receding waters. Consequently the measurement error along 781 the inundation boundary of the survey is likely to vary significantly 782 and somewhat unpredictably. 783 Consequently, an inundation threshold of 10 cm was selected for inundation 784 extents reported in this paper to reflect 785 the more likely accuracy of the survey and subsequently facilitate a more 786 appropriate comparison between the modelled and observed inundation 787 area. 788 Figure~\ref{fig:inundationcomparison1cm} (right) shows the simulated 789 inundation using a larger threshold of 10 cm. 790 784 791 785 792 An animation of this simulation is available on the ANUGA website at \url{https://datamining.anu.edu.au/anuga} or directly from \url{http://tinyurl.com/patong2004}.
