Gippsland Lakes 1% AEP Flood Inundation with 0.2m Sea Level Rise

Gippsland Lakes Local Coastal Hazard Assessment data represents the inundation extent for a 1% Average Exceedance Probability water level event, incorporating a +0.2m increase in mean sea level. The data was produced by the Department of Energy, Environment and Climate Action using hydrodynamic modelling and was last updated on 2026-04 09. It combines catchment inflows, ocean levels, and wind setup to model coastal flooding.

Use Cases

• Flood risk mapping based on the 1% AEP water level and sea level rise scenario.
• Coastal adaptation planning based on modelled inundation extents.
• Hydrodynamic model validation based on the specified combination of inflows, ocean levels, and wind setup.

Strengths

• Models a specific 1% AEP event with a defined +0.2m sea level rise condition.
• Based on hydrodynamic modelling that combines catchment inflows, ocean levels, and wind setup.
• Provided in multiple geospatial formats (DWG, GDB, SHP, MIF, DXF, TAB).

Limitations

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