Woodend Flood Extent Models for Annual Exceedance Probabilities

Flood models for the Woodend area in Victoria, Australia, illustrate the potential inundation extent for 1% and 5% Annual Exceedance Probability (AEP) events, including a 1% AEP scenario with climate change adjustments. The dataset was created and published by the Macedon Ranges Shire Council. It was last updated in April 2026.

Use Cases

• Mapping flood inundation extents for the 1% AEP event to identify high-risk properties and infrastructure.
• Comparing flood extents between the standard 1% AEP and the 1% AEP Climate Change model to assess potential future risk amplification.
• Using the 5% AEP flood model for community education and emergency response planning for more frequent events.
• Integrating the geospatial flood layers with land-use data to evaluate zoning regulations and development suitability.

Strengths

• Models three distinct flood scenarios (1% AEP, 1% AEP Climate Change, 5% AEP) for comparative analysis.
• Data is provided in multiple standard geospatial formats (GEOJSON, SHP, WMS) for interoperability.

Limitations

• The underlying model methodology, input data, and validation details are not provided in the description.
• The spatial coverage is limited to the Woodend area, which may not be representative of broader regional flood patterns.
