Bellarine Peninsula Coastal Inundation Model for 1% AEP Flood Risk

Dynamic inundation modelling results for the Bellarine-Corio Bay coastal environment under a 1% Annual Exceedance Probability scenario with 0m Sea Level Rise in 2016. The data layer includes attributes for maximum depth, velocity, velocity-depth criteria, and water surface elevation. It was produced by the Department of Energy, Environment and Climate Action and is available via the Our Coast project.

Use Cases

• Assess maximum flood depth impacts on infrastructure based on the Max_d attribute.
• Model floodwater velocity for hazard mapping based on the max_s attribute.
• Evaluate combined hydrodynamic hazard using the Velocity*Depth Criteria (max_vxd).
• Plan for water surface elevation impacts on coastal assets based on the max_wse attribute.
• Validate or compare coastal inundation models for specific study areas like Barwon Heads and Queenscliff.

Strengths

• Model outputs include four specific physical impact metrics: maximum depth, velocity, velocity-depth criteria, and water surface elevation.
• The modelling scenario is clearly defined as 1% AEP with 0m Sea Level Rise for the year 2016.
• Project reports detailing assumptions and limitations are referenced via the Our Coast website.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific study areas of the Bellarine Peninsula.
