"""Script for running tsunami inundation scenario for Perth, 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.output_time_dir 

The scenario is defined by a triangular mesh created from project.polygon,
the elevation data and a simulated submarine landslide.
