Bellarine Peninsula Coastal Inundation Model for 1% AEP with 1.4m Sea Level Rise

2016 static (bathtub) inundation modeling for a 1% Annual Exceedance Probability coastal flood event, assuming 1.4 meters of sea level rise. The dataset covers 14 study areas along the Bellarine Peninsula and Greater Geelong coast, including Avalon, Queenscliff, and Portarlington, and was produced by the Department of Energy, Environment and Climate Action. Data units are in meters Australian Height Datum (mAHD), with detailed assumptions and limitations documented in project reports on the Our Coast website.

Use Cases

• Assess coastal flood risk for infrastructure planning based on the 1% AEP inundation extent.
• Model future sea level rise impacts on specific localities like Geelong Waterfront or St Leonards.
• Validate or compare dynamic flood models against static bathtub model results.
• Inform land-use zoning and development controls using hazard extent maps.

Strengths

• Models a specific, high-impact flood probability (1% Annual Exceedance Probability).
• Includes a defined sea level rise scenario of 1.4 meters.
• Covers 14 named study areas providing localized hazard assessment.
• Published under a permissive CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Uses static (bathtub) modeling, which may not account for hydrodynamic processes like waves or barriers.
• Row count and spatial resolution are unknown, which may limit suitability assessment.
