Western Port Coastal Flood Inundation Extent for 10% AEP Event

Western Port, Australia, is the geographic scope for this dataset, which models the shoreline inundation extent for a 10% Average Exceedance Probability catchment-generated flood under current mean sea level. The data was produced by the Department of Energy, Environment and Climate Action as part of the Local Coastal Hazard Assessment and was last updated on 2026-04-09. It is derived from modelling that considers storm surge and catchment inflows for different sea level rise scenarios.

Use Cases

• Assess flood risk for coastal infrastructure based on modelled inundation extents.
• Plan land use and development restrictions based on current sea level flood hazards.
• Validate or calibrate other hydrological models using the provided 10% AEP flood scenario.
• Create visual hazard maps for community engagement and emergency preparedness.

Strengths

• Provides a specific, modelled scenario for a 10% Average Exceedance Probability flood event.
• Covers the entire Western Port coastal environment for a consistent hazard assessment.
• Project reports detailing modelling assumptions and limitations are referenced and available.

Limitations

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