Example of Results

To accurately estimate the extent of damage caused by the 11 March 2011 Tsunami that hit Japan, the actual event has been modelled with the MIKE 21 tsunami model in the MIKE by DHI software suite. We have compared the model results with the available remote sensing information that captured the flood and find good agreement with the model predictions (Figure 1). The model provides detailed information of the tsunami propagation even between the satellite snapshots from space. Moreover, it provides us with the water velocities and hence allows estimating the wave's impacts on structures and buildings.


Figure 1: Model results overlaid on top of the topographic map of Japan. The red areas highlight the calculated maximum inundation. The smaller maps show details from within the area marked with a green circle. The top map shows the inundation as observed from satellite; the bottom map shows the model results of the same area.

Based on the model results and remote sensing data we are now able to provide maps of the inundated areas and tsunami impact. The data can be provided in various grid formats and as kml files for Google Earth or other GIS systems.

In addition, higher resolution model results can be provided on request matching client needs provided data exist. The level of model detail is only limited by the resolution of the available topographic data.
