Gippsland Lakes 10% AEP Inundation Extent with 0.4m Sea Level Rise

The Gippsland Lakes Local Coastal Hazard Assessment (LCHA) provides data on the extent of coastal hazards for the Gippsland Lakes coastal environment. This specific dataset represents the inundation extent for a 10% Average Exceedance Probability (AEP) water level, incorporating 0.4 meters of sea level rise based on hydrodynamic modelling. It was published by the Department of Energy, Environment and Climate Action and was last updated on 2026-04-08.

Use Cases

• Assess flood risk for coastal infrastructure based on the 10% AEP water level and sea level rise scenario.
• Model potential physical impacts of combined catchment inflows, ocean levels, and wind setup on the coastal environment.
• Inform land-use planning and development restrictions based on projected inundation extents.
• Validate or calibrate other hydrodynamic models using the provided hazard extent data.

Strengths

• Specific sea level rise condition of 0.4 meters is defined.
• Hazard extent is derived from hydrodynamic modelling for a defined 10% AEP event.
• Project reports detailing assumptions and methodology are referenced.

Limitations

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