Western Port, Australia, is the geographic scope for this dataset, which models the extent of storm tide inundation for a 1% Average Exceedance Probability event combined with a 0.8-meter sea level rise scenario. The Department of Energy, Environment and Climate Action produced this data using hydrodynamic modeling, and it was last updated on April 8, —2026.
Use Cases
- Assess coastal flood risk for infrastructure planning based on modeled inundation extents.
- Evaluate climate change adaptation strategies based on combined storm tide and sea level rise scenarios.
- Validate or calibrate other hydrodynamic models using the provided inundation hazard data.
- Inform land-use zoning and development restrictions based on projected coastal hazard areas.
Strengths
- Data is based on hydrodynamic modeling for a specific, high-impact scenario (1% AEP storm tide with +0.8m SLR).
- Available in multiple geospatial file formats (DWG, SHP, GDB, DXF, MIF, TAB, EXTENDED TAB) for compatibility with various GIS tools.
- Published under a permissive CC-BY-4.0 license, allowing for broad reuse and adaptation.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and dataset size are unknown, which may limit suitability assessment.
- Users must consult external project reports to fully understand the modeling assumptions and data limitations.
