Port Phillip Bay Coastal Hazard Assessment - Inundation Extent - 1.1m Sea Level Rise (1% A

Port Phillip Bay coastal hazard assessment provides spatial layers for modelled storm tide inundation, erosion, and groundwater hazards. The dataset includes multiple scenarios for sea level rise from 0m to 1.4m and is recommended for regional-scale use. It was produced by organizations including CSIRO and Water Technology, with technical reports cited from 2022 and 2023.

Use Cases

• Model regional coastal flood risk based on storm tide inundation extents for 1% Annual Exceedance Probability scenarios.
• Assess future shoreline change based on erosion hazard extents modelled for different sea level rise and time horizons.
• Identify areas of shallow groundwater hazard based on depth rasters for various sea level rise scenarios.
• Compare hazard outcomes across different percentiles (e.g., 5th, 50th, 95th) for storm tide inundation layers.

Strengths

• Includes multiple hazard types: storm tide inundation, erosion, and groundwater.
• Covers a range of sea level rise scenarios from 0m to 1.4m.
• Storm tide inundation layers incorporate modelled 95th, 50th, and 5th percentiles.
• Erosion hazard extents are provided for specific future years (e.g., 2040, 2070, 2100).

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.
