"""Script for running tsunami inundation scenario for Dampier, WA, Australia.

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

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