Western Port Storm Tide Inundation for 1% AEP with 0.2m Sea Level Rise

Hydrodynamic modelling defines the extent of storm tide inundation for a 1% Average Exceedance Probability event combined with a 0.2-meter sea level rise scenario. The Department of Energy, Environment and Climate Action produced this data for the Western Port coastal environment in Australia. Details and limitations of the modelling assumptions are documented in project reports on the Our Coast website.

Use Cases

• Assess coastal flood risk for infrastructure planning based on the 1% AEP storm tide scenario.
• Model climate change impacts on coastal communities using the +0.2 m sea level rise parameter.
• Validate or inform local hazard mitigation strategies based on the hydrodynamic modelling outputs.
• Create visual hazard maps for public communication based on the spatial inundation extents.

Strengths

• Based on hydrodynamic modelling for specific hazard scenarios (1% AEP, +0.2m SLR).
• Provides spatial extents for a defined coastal environment (Western Port).
• Project reports detailing modelling assumptions and limitations are referenced.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
