1 | """Run a tsunami inundation scenario for Busselton, WA, Australia. |
---|
2 | |
---|
3 | The scenario is defined by a triangular mesh created from project.polygon, the |
---|
4 | elevation data is compiled into a pts file through build_elevation.py and a |
---|
5 | simulated tsunami is generated through an sts file from build_boundary.py. |
---|
6 | |
---|
7 | Input: sts file (build_boundary.py for respective event) |
---|
8 | pts file (build_elevation.py) |
---|
9 | information from project file |
---|
10 | Outputs: sww file stored in project.output_run_time_dir |
---|
11 | The export_results_all.py and get_timeseries.py is reliant |
---|
12 | on the outputs of this script |
