Port Phillip Bay Coastal Hazard Assessment - Shallow Groundwater Extent - 0.2m Sea Level R

Port Phillip Bay coastal hazard assessment provides modelled spatial layers for erosion, inundation, and shallow groundwater extent 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) and Water Technology (2023). It was last updated on 2026-06-15.

Use Cases

• Model regional coastal inundation risk based on storm tide extents for 1% Annual Exceedance Probability scenarios.
• Assess shoreline erosion hazard based on modelled 95th percentile extents for future sea level rise.
• Map areas vulnerable to shallow groundwater (within 0-2m of surface) under different sea level rise projections.

Strengths

• Includes multiple hazard scenarios (inundation, erosion, groundwater) for a range of sea level rise values (0m to 1.4m).
• Data is accompanied by detailed technical reports from CSIRO (2022) and Water Technology (2023).
• Available in multiple geospatial file formats including SHP, GDB, and TAB.

Limitations

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