Coastal Inundation Model for Bellarine Peninsula, 2016 High Flow Scenario

Dynamic inundation modelling for the Bellarine Peninsula and Greater Geelong area provides maximum depth, velocity, and water surface elevation data for a 1% Annual Exceedance Probability flood event. The dataset was created by the Department of Energy, Environment and Climate Action under a 0-meter sea level rise assumption for specific study areas including Barwon Heads and Queenscliff. Details of modelling assumptions and limitations are documented in project reports on the Our Coast website.

Use Cases

• Assess flood risk for infrastructure planning based on maximum depth (Max_d) and water surface elevation (max_wse) attributes.
• Model potential flood damage and evacuation zones using velocity-depth criteria (max_vxd) and maximum velocity (max_s) data.
• Validate other hydrological models for the Bellarine Peninsula using the documented 1% AEP high-flow scenario.
• Inform coastal hazard adaptation strategies by analyzing the spatial extent of inundation under the specified conditions.

Strengths

• Includes four specific modelled attributes: maximum depth, velocity, velocity*depth criteria, and water surface elevation.
• Covers four defined study areas: Barwon Heads / Lake Connewarre, Breamlea, Newcomb, and Queenscliff / Lakers Cutting.
• Published under a permissive CC-BY-4.0 license for reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The model is based on a specific 2016 scenario with 0m sea level rise, which may not reflect current or future conditions.
