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