Bellarine Peninsula Coastal Inundation Model for 1.4m Sea Level Rise

Dynamic inundation modeling for a 1% Annual Exceedance Probability coastal flood event under a 1.4-meter sea level rise scenario. The dataset, created by the Department of Energy, Environment and Climate Action, covers study areas including Barwon Heads, Breamlea, Newcomb, and Queenscliff on the Bellarine Peninsula. It includes attributes for maximum depth, velocity, and water surface elevation.

Use Cases

• Assess flood risk and infrastructure vulnerability based on maximum depth and water surface elevation attributes.
• Model potential evacuation routes and emergency response based on maximum velocity data.
• Inform coastal development and land-use planning based on the inundation extent for a high-probability storm surge scenario.
• Validate or compare other hydrological models using the velocity*depth criteria attribute.

Strengths

• Modeled for a specific, high-impact scenario combining a 1% AEP storm event with 1.4m of sea level rise.
• Includes four key physical impact attributes: maximum depth, velocity, velocity*depth, and water surface elevation.
• Published under a permissive CC-BY-4.0 license for broad reuse.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
