Western Port Coastal Inundation Extent for 10% AEP Flood Under 0.5m Sea Level Rise

The Western Port Local Coastal Hazard Assessment provides modelled inundation extents for storm surge and catchment inflows. This data represents shoreline inundation for a 10% Average Exceedance Probability catchment flood under a +50cm sea level rise scenario. The Department of Energy, Environment and Climate Action published this data, which was last updated on 2026-04-09.

Use Cases

• Map coastal flood inundation extent based on modelled storm surge scenarios.
• Assess land vulnerability to flooding based on catchment inflow modelling.
• Plan coastal adaptation strategies based on sea level rise scenarios.
• Validate flood hazard models based on the documented assumptions and limitations.

Strengths

• Data is based on modelling for specific sea level rise scenarios (+50cm).
• Inundation hazards are defined for a specific probability event (10% AEP).
• Project reports detailing assumptions and limitations are referenced and available.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
