Port Phillip Bay Coastal Hazard Assessment

A digital dataset from the Department of Energy, Environment and Climate Action provides multiple spatial layers for modeled coastal hazards around Port Phillip Bay. The data includes storm tide inundation, erosion, and groundwater hazard extents for various Sea Level Rise scenarios, such as 0m, 0.2m, 0.5m, 0.8m, 1.1m, and 1.4m. The product was last updated on 2026-04 09 and is accompanied by technical reports from CSIRO (2022), Water Technology (2023), and Kennedy (2022).

Use Cases

• Assessing regional-scale flood risk based on modeled storm tide inundation extents for different sea level rise scenarios.
• Mapping potential coastal erosion zones based on the 1% Annual Exceedance Probability erosion hazard extents.
• Identifying areas at risk from shallow groundwater based on the groundwater depth raster-derived extents.
• Conducting comparative hazard analysis using the combined vector layers that incorporate the 95th, 50th, and 5th percentile modeled outcomes.

Strengths

• Covers three distinct hazard types: storm tide inundation, erosion, and groundwater.
• Provides data for six specific Sea Level Rise scenarios (0m, 0.2m, 0.5m, 0.8m, 1.1m, 1.4m).
• Includes multiple file formats for spatial data (DWG, GDB, SHP, MIF, DXF, EXTENDED TAB, TAB).
• Is supported by multiple technical reports from authoritative sources like CSIRO.

Limitations

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