Port Phillip Bay Coastal Hazard Assessment for Shallow Groundwater Extent

A geospatial dataset from the Port Phillip Bay Coastal Hazard Assessment project models shallow groundwater extent hazards for sea level rise scenarios up to 1.4 meters. The dataset is produced by the Department of Energy, Environment and Climate Action and includes layers for groundwater, erosion, and storm tide inundation. The data was last updated on April 9, 2026.

Use Cases

• Regional-scale coastal hazard mapping based on modelled groundwater, erosion, and inundation scenarios.
• Comparing groundwater hazard extents across different sea level rise projections.
• Integrating storm tide inundation layers with rainfall data for compound risk analysis.
• Assessing erosion hazard extents for specific future years and sea level rise levels.

Strengths

• Includes multiple hazard types: groundwater, erosion, and storm tide inundation.
• Provides data for a range of sea level rise scenarios (0m to 1.4m).
• Storm tide inundation layers incorporate modelled 95th, 50th, and 5th percentile outputs.
• Supported by technical reports from CSIRO (2022), Water Technology (2023), and Kennedy (2022).

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.
• The product is not suitable for individual property scale assessments.
