Port Phillip Bay Coastal Hazard Assessment for Erosion and Inundation

Port Phillip Bay Coastal Hazard Assessment is a digital dataset of modelled erosion, inundation, and groundwater hazard scenarios for the Port Phillip Bay region. The data includes extents for 1% Annual Exceedance Probability events across multiple sea level rise scenarios, from 0m to 1.4m. The product was developed with technical reports from CSIRO (2022), Water Technology (2023), and Kennedy (2022).

Use Cases

• Assess regional-scale coastal erosion risk based on modelled 95th percentile erosion extents.
• Model storm tide inundation under different sea level rise scenarios based on combined vector layers.
• Identify areas with shallow groundwater hazards (within 0-2m of the surface) for various sea level rise projections.
• Plan long-term coastal adaptation strategies based on hazard projections for years 2010, 2040, 2070, and 2100.

Strengths

• Includes multiple hazard types: erosion, inundation, and groundwater.
• Covers a range of sea level rise scenarios from 0m to 1.4m.
• Provides data for specific future years (e.g., 2040, 2070, 2100).
• Released under a CC-BY-4.0 license.

Limitations

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