Port Phillip Bay Coastal Hazard Assessment for Shallow Groundwater Extent

A geospatial dataset from the Port Phillip Bay Coastal Hazard Assessment modeling shallow groundwater extent for sea level rise scenarios. The product includes multiple hazard layers for erosion, inundation, and groundwater, modeled for scenarios including a 1.1m sea level rise. It was produced by CSIRO, Water Technology, and Kennedy (2022-2023) for the Department of Energy, Environment and Climate Action.

Use Cases

• Model regional coastal groundwater hazards based on sea level rise scenarios.
• Assess combined storm tide inundation risks based on percentile layers.
• Plan for future erosion hazard extents based on projected sea level rise.
• Compare groundwater depth impacts under different sea level rise assumptions.

Strengths

• Includes multiple hazard types: erosion, inundation, and groundwater.
• Models scenarios for specific sea level rise values (0m, 0.2m, 0.5m, 0.8m, 1.1m).
• Provides combined vector layers incorporating 95th, 50th, and 5th percentile data for storm tide inundation.
• 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.
• Row count is unknown, which may limit suitability assessment.
• The product is not suitable for individual property scale assessments, limiting granular applications.
