Western Port Storm Tide Inundation Extent for 1% AEP at Current Sea Level

The Western Port Local Coastal Hazard Assessment provides modelled storm tide inundation extents for the 1% Average Exceedance Probability event at current mean sea level. This data was produced by the Department of Energy, Environment and Climate Action using hydrodynamic modelling for different sea level rise scenarios. The dataset was last updated on 2026-04-09.

Use Cases

• Map coastal flood risk for infrastructure planning based on the 1% AEP storm tide inundation extent.
• Model climate change impacts on coastal communities based on sea level rise scenarios mentioned in the description.
• Assess physical impacts of storm surge on the coastal environment as described in the Local Coastal Hazard Assessment.
• Validate or calibrate other hydrodynamic models using the provided inundation extents.

Strengths

• Data is based on hydrodynamic modelling for specific sea level rise scenarios.
• Inundation extent is defined for a precise 1% Average Exceedance Probability storm tide event.
• Project reports detailing assumptions and methodology are available via the Our Coast website.

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 read external project reports to understand the data's limitations.
