Port Phillip Bay Coastal Hazard Assessment for 1.1m Sea Level Rise with Rainfall

Port Phillip Bay Coastal Hazard Assessment is a digital dataset of modelled erosion, inundation, and groundwater hazard scenarios for the Port Phillip Bay region. The dataset includes multiple spatial layers for storm tide inundation, erosion, and shallow groundwater extents under various sea level rise scenarios. Technical reports from CSIRO (2022), Water Technology (2023), and Kennedy (2022) accompany the data.

Use Cases

• Assess regional-scale coastal inundation risk based on modelled 1% Annual Exceedance Probability storm tide extents.
• Plan for long-term coastal erosion under projected sea level rise scenarios up to 1.4 meters.
• Evaluate shallow groundwater hazard areas where water tables are within 0 to 2 meters of the land surface.
• Compare combined hazard impacts from storm tide and rainfall for different sea level rise futures.

Strengths

• Includes multiple hazard types: storm tide inundation, erosion, and groundwater.
• Models a range of sea level rise scenarios from 0m to 1.4m.
• Storm tide layers incorporate modelled 95th, 50th, and 5th percentile outcomes.
• Accompanied by detailed technical reports from CSIRO and other institutions.

Limitations

• Not suitable for individual property scale assessments, as stated in the description.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
