Port Phillip Bay Coastal Hazard Assessment: Inundation Extent for 0.8m Sea Level Rise

Port Phillip Bay coastal hazard data includes modelled storm tide inundation, erosion, and groundwater extents for various sea level rise scenarios. The dataset is a digital spatial product from technical reports by CSIRO (2022), Water Technology (2023), and Kennedy (2022). It is recommended for regional-scale assessments around Port Phillip Bay and is not suitable for individual property analysis.

Use Cases

• Modeling regional-scale coastal inundation risk based on storm tide and sea level rise scenarios.
• Assessing potential erosion hazard extents for different future time horizons and sea level conditions.
• Identifying areas with shallow groundwater hazards likely to be impacted by sea level rise.
• Comparing hazard outcomes across different probability percentiles (e.g., 5th, 50th, 95th).

Strengths

• Includes multiple hazard types: storm tide inundation, erosion, and groundwater.
• Covers a range of sea level rise scenarios from 0m to 1.4m for inundation.
• Inundation layers incorporate modelled 95th, 50th, and 5th percentiles.
• Erosion extents are provided for specific future years (e.g., 2040, 2070, 2100) paired with sea level rise.

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.
