Western Port Storm Tide Inundation Extent for 1% AEP with 0.5m Sea Level Rise

Western Port, Australia, is the geographic scope for this dataset, which models the extent of storm tide inundation for a 1% Annual Exceedance Probability event combined with a 0.5-meter sea level rise scenario. The Department of Energy, Environment and Climate Action produced the data using hydrodynamic modeling. The dataset was last updated on April 9, 2026.

Use Cases

• Assess coastal flood risk for infrastructure planning based on modeled inundation extents.
• Inform land-use zoning and development restrictions based on sea level rise and storm surge scenarios.
• Validate or calibrate other hydrodynamic models using the provided inundation hazard data.
• Support community awareness and emergency preparedness for storm tide events.

Strengths

• Models a specific, high-impact scenario (1% AEP storm tide with +0.5m SLR).
• Derived from hydrodynamic modeling, suggesting a physics-based approach.
• Project reports detailing modeling assumptions are referenced for transparency.
• Available in multiple geospatial file formats (SHP, GDB, TAB, etc.).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and spatial resolution are unknown, which may limit suitability assessment.
• Users must consult external project reports to fully understand data limitations.
