1 | """Script for running a tsunami inundation scenario for Cairns, QLD 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 directory named after the scenario, i.e |
---|
6 | slide or fixed_wave. |
---|
7 | |
---|
8 | The scenario is defined by a triangular mesh created from project.polygon, |
---|
9 | the elevation data and a tsunami wave generated by a submarine mass failure. |
