Victorian Coastal Inundation Sea Level Rise Projections to 2100

Eight spatial layers model land extent subject to coastal inundation due to projected sea level rise from 2009 to 2100. The dataset includes projections for 20cm, 47cm, and 82cm of sea level rise by 2040, 2070, and 2100, respectively, and combines these with 1-in-100 year storm tide levels. It was computed for the Victorian Government's Future Coasts Project by the Department of Energy, Environment and Climate Action.

Use Cases

• Model regional-scale coastal flood risk based on projected sea level rise layers.
• Assess long-term land use planning scenarios based on storm tide inundation with sea level rise.
• Visualize potential future coastline changes for public communication based on the spatial layers.

Strengths

• Provides eight distinct spatial layers for different scenarios and timeframes.
• Includes specific sea level rise projections (20cm, 47cm, 82cm) for 2040, 2070, and 2100.
• Available in multiple geospatial file formats (DWG, GDB, SHP, MIF, DXF, EXTENDED TAB, TAB).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The product is explicitly not suitable for property-level risk assessments.
