Victorian Coastal Inundation: Sea Level Rise and Storm Tide Projections 2009-2100

Victoria, Australia's coastal inundation dataset contains eight spatial layers modelling land subject to flooding from projected sea level rise and 1-in-100-year storm tides from 2009 to 2100. The data supports the Victorian Government's Future Coasts Project and is intended for regional-scale assessments at approximately 1:75,000 scale. It is not suitable for property-level risk analysis.

Use Cases

• Regional coastal hazard planning based on projected sea level rise layers for 2040, 2070, and 2100.
• Storm surge risk assessment using modelled 1-in-100-year storm tide inundation layers combined with sea level rise.
• Long-term climate adaptation strategy development based on multi-decadal coastal inundation projections.
• Identifying vulnerable coastal areas by analysing the spatial extent of modelled inundation under different scenarios.

Strengths

• Provides a multi-decadal time series of projections from 2009 to 2100, covering four specific years.
• Includes eight distinct modelled scenarios, separating sea level rise only from combined storm tide and sea level rise events.
• Explicitly documented as being for regional-scale use (1:75,000), clarifying its appropriate application scope.

Limitations

• Explicitly stated as not suitable for property-level risk assessments, limiting granular use cases.
• Specific column names and data structure details are not provided in the available metadata.
• An associated interactive map service (Hydra) was decommissioned in October 2022, reducing accessibility.
