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

Multiple spatial layers from the Port Phillip Bay Coastal Hazard Assessment, modelled for erosion, inundation, and groundwater scenarios. The dataset includes storm tide inundation extents for a 1% Annual Exceedance Probability event combined with 0.8 meters of sea level rise and rainfall. It was produced by CSIRO, Water Technology, and Kennedy (2022-2023) and published by the Department of Energy, Environment and Climate Action.

Use Cases

• Modeling regional-scale flood risk based on combined storm tide and rainfall scenarios.
• Assessing coastal erosion hazard extents based on the modelled 95th percentile.
• Identifying areas with shallow groundwater hazards (within 0-2m of surface) under different sea level rise projections.
• Comparing hazard scenarios across multiple sea level rise increments (e.g., 0m, 0.5m, -0.8m, 1.1m, 1.4m).

Strengths

• Includes multiple hazard types (inundation, erosion, groundwater) across a range of sea level rise scenarios.
• Storm tide inundation layers incorporate modelled 95th, 50th, and 5th percentiles.
• Technical reports from CSIRO (2022), Water Technology (2023), and Kennedy (2022) provide detailed methodology.

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, limiting granular applications.
