Gippsland Lakes Coastal Hazard Extent Under Sea Level Rise Scenarios

The Gippsland Lakes Local Coastal Hazard Assessment maps potential coastal hazard zones under four specific sea level rise scenarios: 0.0m, 0.2m, 0.4m, and 0.8m. It includes hazards associated with storm erosion, longshore sediment transport gradients, equilibrium profile adjustment, and wave overwash processes. The data was produced by the Department of Energy, Environment and Climate Action and was last updated in April 2026.

Use Cases

• Modeling coastal erosion risk based on sea level rise scenarios mentioned in the description
• Planning shoreline infrastructure based on mapped hazard zones for storm erosion and wave overwash
• Assessing sediment transport impacts based on longshore sediment transport gradients

Strengths

• Provides hazard extent for four specific sea level rise scenarios (0.0m, 0.2m, 0.4m, 0.8m)
• Includes multiple hazard processes: storm erosion, sediment transport, profile adjustment, and wave overwash
• Available in multiple GIS file formats (DWG, MIF, DXF, SHP, GDB, TAB) for interoperability

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to the Gippsland Lakes region
