Bellarine Peninsula Coastal Flood Model for 1% AEP with 1.1m Sea Level Rise

Dynamic inundation modelling for a 1% Annual Exceedance Probability coastal flood event, assuming a 1.1-meter sea level rise in 2016. The dataset covers four study areas along the Bellarine Peninsula and Greater Geelong coast, including Barwon Heads and Queenscliff. It was produced by the Department of Energy, Environment and Climate Action and provides attributes like maximum flood depth and water surface elevation.

Use Cases

• Modeling coastal flood extents and depths based on the dynamic inundation data.
• Assessing infrastructure vulnerability based on maximum water surface elevation (max_wse).
• Evaluating hydrodynamic hazard criteria using the velocity*depth (max_vxd) attribute.
• Planning for sea level rise adaptation based on the 1.1m scenario and 1% AEP event.

Strengths

• Models a specific, high-impact scenario combining a 1% AEP flood with a 1.1-meter sea level rise.
• Includes four defined study areas (e.g., Barwon Heads, Breamlea) for localized analysis.
• Provides key hazard metrics like maximum depth (Max_d) and maximum velocity (max_s).
• Published under a permissive CC-BY-4.0 license for reuse.

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be fully inferred after download.
• Users must consult external project reports to understand the modelling assumptions and data limitations.
