Port Phillip Bay Coastal Hazard Assessment for Shallow Groundwater Extent

Port Phillip Bay Coastal Hazard Assessment models erosion, inundation, and groundwater hazards under various sea-level rise scenarios. The dataset includes multiple spatial layers for a 1% Annual Exceedance Probability storm tide, with groundwater extents indicating where water is within 0 to 2 meters of the surface. It was produced by CSIRO, Water Technology, and Kennedy (2022-2023) for the Department of Energy, Environment and Climate Action.

Use Cases

• Modeling coastal inundation risk based on storm tide extents for 0m to 1.4m sea-level rise scenarios.
• Assessing erosion hazard based on 95th percentile modelled extents for future time periods.
• Identifying areas vulnerable to shallow groundwater rise based on depth-to-water rasters.
• Conducting regional-scale climate adaptation planning using combined hazard percentile layers.

Strengths

• Includes multiple hazard types (inundation, erosion, groundwater) across consistent scenarios.
• Provides data for a 1% Annual Exceedance Probability event across 6 sea-level rise scenarios for groundwater.
• Accompanied by detailed technical reports from CSIRO (2022), Water Technology (2023), and Kennedy (2022).
• Data is provided in multiple geospatial formats including SHP, GDB, and TAB.

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 its granular application.
