Inverloch Coastal Hazard Assessment: Erosion Zones for Sea Level Rise Scenarios

A 2021 modelled dataset assessing erosion hazard zones in the Inverloch region of Australia. The dataset was produced by the Department of Energy, Environment and Climate Action and models sea level rise components of 0m (2020), 0.2m (2040), 0.5m (2070), and 0.8m (2100) against 1%, 5%, and 10% annual exceedance probability storm events.

Use Cases

• Modeling coastal erosion risk based on projected sea level rise scenarios.
• Assessing storm event impacts on shorelines based on annual exceedance probability.
• Informing land-use planning and development restrictions based on hazard zone delineation.
• Visualizing geospatial hazard zones for public communication and policy development.

Strengths

• Models four specific sea level rise projections (0m, 0.2m, 0.5m, 0.8m) tied to planning horizons.
• Assesses three distinct storm event intensities (1%, 5%, 10% AEP) for hazard analysis.
• Available under a permissive CC-BY-4.0 license for reuse and adaptation.
• Offered in multiple geospatial file formats (DWG, SHP, GDB, etc.) for compatibility with various tools.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic and modeling bias inherent to the specific study area and methodology.
