Western Port Coastal Inundation for 10% AEP Flood with 0.2m Sea Level Rise

The Western Port Local Coastal Hazard Assessment provides modeled data on the extent of shoreline inundation for the Western Port coastal environment in Australia. This specific dataset represents the inundation extent for a 10% Average Exceedance Probability catchment-generated flood under a +20cm sea level rise scenario. The data was produced by the Department of Energy, Environment and Climate Action and was last updated on 2026-04 09.

Use Cases

• Modeling coastal flood risk based on storm surge and catchment inflow scenarios.
• Assessing infrastructure vulnerability based on projected inundation extents.
• Planning for climate adaptation and coastal management based on sea level rise scenarios.
• Visualizing potential flood impact zones for community engagement and emergency planning.

Strengths

• Data is derived from a formal Local Coastal Hazard Assessment (LCHA) modeling process.
• Specific scenario details are provided (10% AEP flood, +20cm sea level rise).
• Project reports detailing assumptions and methodology are referenced for transparency.
• Available in multiple geospatial file formats (SHP, GDB, DXF, etc.) for interoperability.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and data size are unknown, which may limit suitability assessment.
• Users must read referenced project reports to understand the full limitations of the data.
