Port Phillip Bay Coastal Hazard Assessment: Inundation Extent for 0.0m Sea Level Rise

Multiple spatial layers from modelled erosion, inundation, and groundwater hazard scenarios for the Port Phillip Bay region. The dataset is recommended for regional-scale assessment and is not suitable for individual property scale. It was produced by CSIRO, Water Technology, and Kennedy (2022-2023) and last updated on 2026-06-15.

Use Cases

• Model regional-scale coastal inundation risk based on storm tide scenarios with 1% Annual Exceedance Probability.
• Assess combined hazard impacts based on layers incorporating modelled 95th, 50th, and 5th percentiles.
• Plan for future erosion extents based on projections for sea level rise scenarios up to 1.4 meters.
• Evaluate shallow groundwater hazard areas based on depth rasters for various sea level rise scenarios.

Strengths

• Covers multiple hazard types: storm tide inundation, erosion, and groundwater.
• Includes scenarios for a range of Sea Level Rise values (0m, 0.2m, 0.5m, 0.8m, 1.1m, 1.4m).
• Storm tide inundation extents are presented as combined vector layers with multiple percentile outputs.
• Technical reports from CSIRO (2022), Water Technology (2023), and Kennedy (2022) provide detailed methodology.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
