Victorian Coastal Cliff Hazard Assessment with Sea Level Rise Scenarios, 2023

Multiple spatial layers model erosion-susceptible areas and risk for the Victorian coastline. The dataset includes hazard areas for six sea level rise scenarios and aggregated risk ratings for 24 coastal compartments. The Department of Energy, Environment and Climate Action produced this update, superseding a prior Stage 1 assessment.

Use Cases

• Model coastal cliff instability hazard areas based on present-day and future sea level rise scenarios.
• Assess aggregated cliff risk ratings for human health, infrastructure, and environment across defined coastal compartments.
• Plan regional-scale coastal management strategies based on short-term (to 2040), medium-term (2040-2070), and long-term (2070-2100) risk scores.

Strengths

• Includes six distinct sea level rise scenarios for hazard modeling, from present day to 2100.
• Risk assessment covers seven specific attributes: human health, access, environment, cultural, property, infrastructure, and economy.
• Spatial data is provided in multiple industry-standard geospatial formats (SHP, TAB, GDB, etc.).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• The product is explicitly not suitable for individual property scale assessments.
• Column-level documentation is absent; field semantics must be inferred after download.
