1"""Script for running tsunami inundation scenario for Perth, WA, Australia.
2
3Source data such as elevation and boundary data is assumed to be available in
4directories specified by project.py
5The output sww file is stored in project.output_time_dir
6
7The scenario is defined by a triangular mesh created from project.polygon,
8the elevation data and a simulated submarine landslide.
