Port Phillip Bay Coastal Hazard Assessment - Erosion Extent - 2010 - 0.0m Sea Level Rise (

A 2010 baseline scenario from the Port Phillip Bay Coastal Hazard Assessment, a digital dataset of modelled erosion, inundation, and groundwater hazard scenarios. The product consists of multiple spatial layers and is recommended for regional-scale use around Port Phillip Bay, guided by technical reports from CSIRO (2022), Water Technology (2023), and Kennedy (2022).

Use Cases

• Assess regional coastal erosion risk based on modelled 95th percentile erosion extents.
• Model storm tide inundation scenarios based on combined vector layers incorporating 95th, 50th, and 5th percentile data.
• Evaluate shallow groundwater hazard areas based on extents indicating water within 0 to 2 meters of the land surface.
• Compare coastal hazard impacts across different Sea Level Rise scenarios (e.g., 0m, 0.5m, 0.8m, 1.1m).

Strengths

• Includes multiple hazard types (erosion, inundation, groundwater) across a range of Sea Level Rise scenarios.
• Based on technical reports from authoritative institutions including CSIRO (2022).
• Erosion extents are modelled at the 95th percentile for a 1% Annual Exceedance Probability event.

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 explicitly stated as not suitable for individual property-scale assessments.
