Bellarine Peninsula Coastal Inundation Model for 1% AEP with 0.8m Sea Level Rise

Dynamic inundation modelling for a 1% Annual Exceedance Probability coastal flood event under a 0.8-meter sea level rise scenario in 2016. The dataset covers four study areas along the Bellarine Peninsula and Greater Geelong, including Barwon Heads and Queenscliff, and was produced by the Department of Energy, Environment and Climate Action. Attribute information includes maximum depth, velocity, and water surface elevation.

Use Cases

• Assess maximum flood depth and extent for infrastructure planning based on the Max_d attribute.
• Model hydrodynamic forces on structures using the max_s (maximum velocity) attribute.
• Evaluate combined hazard severity using the max_vxd (Velocity*Depth Criteria) metric.
• Analyze flood water surface elevation relative to a datum (mAHD) using the max_wse attribute.

Strengths

• Includes four specific coastal study areas: Barwon Heads / Lake Connewarre, Breamlea, Newcomb, and Queenscliff / Lakers Cutting.
• Models a specific 1% Annual Exceedance Probability event with a defined 0.8-meter sea level rise assumption.
• Provides multiple vector geospatial file formats (SHP, GDB, DXF) for compatibility with various GIS tools.

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment.
• Column-level documentation is absent beyond the four listed attributes; field semantics must be fully inferred after download.
• Data may reflect geographic and modeling bias inherent to the specific 2016 scenario and study areas.
