"""Script for running a tsunami inundation scenario for Karratha, WA, Australia.

Source data such as elevation and boundary data is assumed to be available in
directories specified by project.py
The output sww file is stored in project.outputdir 

The scenario is defined by a triangular mesh created from project.polygon,
the elevation data and boundary data obtained from a tsunami simulation done with MOST.
