Bellarine Peninsula Coastal Inundation Model for 1% AEP with 0.5m Sea Level Rise

Dynamic inundation modelling was carried out for a 1% Annual Exceedance Probability coastal inundation scenario assuming 0.5 meters of Sea Level Rise in 2016. The model covers four study areas along the coast of the Bellarine Peninsula and Greater Geelong area: Barwon Heads / Lake Connewarre, Breamlea, Newcomb, and Queenscliff / Lakers Cutting. The Department of Energy, Environment and Climate Action created this data layer, and details of assumptions and limitations are documented in project reports on the Our Coast website.

Use Cases

• Assess maximum flood depth (Max_d) for coastal infrastructure planning.
• Evaluate flood hazard severity using the Velocity*Depth Criteria (max_vxd) metric.
• Model maximum water surface elevation (max_wse) for flood mapping and emergency response.
• Analyze maximum flow velocity (max_s) for understanding hydrodynamic impacts.

Strengths

• Model is based on a specific 1% Annual Exceedance Probability (AEP) scenario.
• Includes four defined study areas: Barwon Heads / Lake Connewarre, Breamlea, Newcomb, and Queenscliff / Lakers Cutting.
• Provides four specific attribute fields: Max_d, max_s, max_vxd, and max_wse.
• Project reports detailing assumptions and limitations are referenced for user guidance.

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment.
• Column-level documentation beyond the four listed attributes is absent; field semantics for other potential columns must be inferred after download.
• Data may reflect geographic bias inherent to the specific Bellarine Peninsula and Greater Geelong area.
