"""Script for running a tsunami inundation scenario for Cairns, QLD 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 directory named after the scenario, i.e
slide or fixed_wave.

The scenario is defined by a triangular mesh created from project.polygon,
the elevation data and a tsunami wave generated by a submarine mass failure.
