Inverloch Coastal Erosion Hazard Zones for Sea Level Rise Scenarios to 2100

A modelled geospatial dataset assessing coastal erosion hazard zones for the Inverloch region in Victoria, Australia. The dataset was produced by the Department of Energy, Environment and Climate Action and models sea level rise scenarios of 0m (2020), 0.2m (2040), 0.5m (2070), and 0.8m (2100) combined with storm events of 1%, 5%, and 10% annual exceedance probability. It was last updated on 2026-04-27.

Use Cases

• Mapping future coastal erosion risk zones based on modelled sea level rise and storm surge scenarios.
• Assessing land-use and development vulnerability for different planning horizons (2020, 2040, 2070, 2100).
• Informing coastal setback policies and infrastructure planning using hazard zone delineations.
• Calibrating or validating other coastal erosion models with the provided design storm events (1%, 5%, 10% AEP).

Strengths

• Models four specific sea level rise scenarios (0m, 0.2m, 0.5m, 0.8m) tied to planning years.
• Incorporates three distinct storm event probabilities (1%, 5%, 10% AEP) for hazard assessment.
• Available in multiple standard geospatial formats (SHP, DXF, GDB, etc.) for interoperability.
• Published under a permissive CC-BY-4.0 license for reuse and adaptation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data may reflect geographic and modelling bias inherent to the specific study area and methods.
