Gippsland Lakes 10% AEP Mean Sea Level Inundation Extent

Gippsland Lakes coastal hazard data represents the inundation extent for a 10% Average Exceedance Probability water level under current mean sea level conditions. The dataset was created by the Department of Energy, Environment and Climate Action using hydrodynamic modelling that combines catchment inflows, ocean levels, and wind setup. It was last updated on April 9, 2026.

Use Cases

• Model flood risk for infrastructure planning based on the 10% AEP water level extent.
• Assess coastal hazard impacts on land use based on the inundation mapping.
• Validate or calibrate hydrodynamic models using the provided extent data.
• Inform emergency management and evacuation planning based on the hazard assessment.

Strengths

• Based on hydrodynamic modelling incorporating catchment inflows, ocean levels, and wind setup.
• Provides a specific, defined hazard scenario (10% AEP water level).
• Available in multiple geospatial file formats (SHP, GDB, DXF, etc.) for flexibility.
• Last updated date is explicitly provided (2026-04-09).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Users must read external project reports to understand the full limitations of the data.
