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

A static bathtub inundation model shows the extent of a 1% Annual Exceedance Probability coastal flood for the Bellarine Peninsula and Greater Geelong area, assuming a 0.8-meter sea level rise. The data was created in 2016 by the Department of Energy, Environment and Climate Action for 14 specific study areas along the coast. Units for the model are in meters Australian Height Datum (mAHD).

Use Cases

• Assess coastal flood risk for infrastructure planning based on the 1% AEP inundation extent.
• Model climate change impacts on specific coastal communities using the 0.8m sea level rise scenario.
• Compare hazard exposure across 14 study areas like Portarlington and Queenscliff using the geospatial data layer.
• Inform land-use and development policies based on the static inundation model outputs.

Strengths

• Model covers 14 distinct coastal study areas for detailed local analysis.
• Data is provided in 7 different geospatial file formats (DWG, MIF, SHP, etc.) for compatibility.
• Published under a permissive CC-BY-4.0 license for reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Uses a static 'bathtub' modeling approach, which may not account for dynamic wave or erosion effects.
• Row count and dataset size are unknown, which may limit suitability assessment.
