"""Script for running a tsunami inundation scenario for Onslow, 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 a simulated submarine landslide.
