Port Phillip Bay Coastal Hazard Assessment for 0.5m Sea Level Rise

Multiple spatial layers model storm tide inundation, erosion, and groundwater hazards for Port Phillip Bay under various sea level rise scenarios. The dataset is recommended for regional-scale use and is accompanied by technical reports from CSIRO (2022), Water Technology (2023), and Kennedy (2022). It was last updated on June 15, 2026, by the Department of Energy, Environment and Climate Action.

Use Cases

• Model regional coastal inundation risk based on storm tide extents for a 1% Annual Exceedance Probability.
• Assess future shoreline erosion based on projected sea level rise scenarios up to 1.4 meters.
• Identify areas with shallow groundwater hazards likely to be exacerbated by sea level rise.
• Compare combined hazard impacts using layers that incorporate the 95th, 50th, and 5th percentile model results.

Strengths

• Includes multiple hazard types (inundation, erosion, groundwater) for a comprehensive risk profile.
• Models a range of specific sea level rise scenarios (0m, 0.2m, 0.5m, 0.8m, 1.1m, 1.4m).
• Supported by cited technical reports from CSIRO, Water Technology, and Kennedy.
• Available in multiple geospatial file formats (TAB, SHP, GDB, etc.) for interoperability.

Limitations

• The product is explicitly stated as not suitable for individual property-scale assessments.
• Row count and column-level documentation are unknown, requiring manual inspection after download.
• Data may reflect modeling assumptions and geographic bias specific to the Port Phillip Bay region.
