Port Phillip Bay Shallow Groundwater Extent for 0.8m Sea Level Rise

Multiple spatial layers model coastal hazards for Port Phillip Bay, including storm tide inundation, erosion, and shallow groundwater extent. The product is recommended for regional-scale use and is based on technical reports from CSIRO (2022), Water Technology (2023), and Kennedy (2022). It includes scenarios for sea level rises of 0m, 0.2m, 0.5m, 0.8m, 1.1m, and 1.4m.

Use Cases

• Modeling coastal inundation risk based on storm tide extents for 1% Annual Exceedance Probability scenarios.
• Assessing shoreline erosion hazard based on modelled 95th percentile extents for future sea level rise scenarios.
• Mapping areas at risk from shallow groundwater rise (within 0 to 2m of land surface) under different sea level rise conditions.

Strengths

• Includes multiple hazard types (inundation, erosion, groundwater) across a range of sea level rise scenarios.
• Data is accompanied by detailed technical reports from CSIRO, Water Technology, and Kennedy.
• Available in multiple common geospatial file 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 granularity.
