Port Phillip Bay Coastal Hazard Assessment for Storm Tide Inundation and Erosion

Multiple spatial layers model storm tide inundation, erosion, and groundwater hazards for Port Phillip Bay under various sea level rise scenarios. The dataset is produced by the Department of Energy, Environment and Climate Action, with technical reports from CSIRO (2022), Water Technology (2023), and Kennedy (2022). It was last updated on 2026-06-14.

Use Cases

• Model regional-scale coastal inundation risk based on sea level rise scenarios.
• Assess erosion hazard extents for different future time horizons.
• Identify areas at risk from shallow groundwater based on modelled depth.
• Compare hazard scenarios that incorporate rainfall with those that do not.

Strengths

• Includes multiple hazard types: inundation, erosion, and groundwater.
• Provides data for a range of sea level rise scenarios from 0m to 1.4m.
• Inundation layers incorporate modelled 95th, 50th, and 5th percentile estimates.
• Supported by detailed technical reports from CSIRO and other organizations.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• The product is explicitly stated as not suitable for individual property scale assessments.
• Column-level documentation is absent; field semantics must be inferred after download.
