12. INTERPRETATION OF TUNAMI-N2 OUTPUT FILES
The output of TUNAMI-N2 program is not easily interpreted as given in the output files. In order to get the
best results, the output files are needed to be converted in to diagrams or graphs so that the interpretation
and the comparison of different data can be achieved easily.
Using t***.grd files and the bathymetry file of the area, the simulation of the tsunami is accomplished.
Plotting the elevsurface.dat for specific coordinates where the tidal gauges are located, comparison of the
real time data and the numerical analysis of the tsunami can be done which is a way of checking the
accuracy of the simulation.
Plotting the runup file enables another check of accuracy for the simulation and the input parameters by
comparing the post tsunami survey measurements and the output of the runup routine.
The diagrams or the graphs of the output files are mostly prepared by using the programs Surfer, Grapher
and/or Microsoft Office Excel. To learn about these programs, please refer to the help menus of each
software.
