updates to mandurah and bunbury storm surge models

File size: 7.1 KB
Line 
1"""Run a storm surge inundation scenario for Mandurah, WA, Australia using
2input from the third party consultant GEMS.
3
4The scenario is defined by a triangular mesh created from project.polygon, the
5elevation data is compiled into a pts file through build_elevation.py and a
6simulated storm surge is generated from GEMS data.
7
8Input: sts files (csv format time series at ocean boundary for respective event)
9       pts file (build_elevation.py)
10       information from project file
11Outputs: sww file stored in project.output_run_time_dir
12The export_results_all.py and get_timeseries.py is reliant
13on the outputs of this script
