Woodend Flood Extent Models for Annual Exceedance Probabilities

Flood models for the Woodend, Victoria area illustrate the spatial extent of floodwaters for three scenarios: a 1% Annual Exceedance Probability event, a 1% AEP event with climate change adjustments, and a 5% AEP event. The dataset is provided by the Macedon Ranges Shire Council and was last updated in April 2026. It is available in multiple geospatial formats including QGIS, GeoJSON, and Shapefile.

Use Cases

• Compare flood extent polygons between the 1% AEP and 5% AEP scenarios to identify high-risk zones for development planning.
• Analyze the 1% AEP Climate Change layer to assess potential future flood risk increases for long-term adaptation strategies.
• Use the geospatial flood boundaries to overlay with property or infrastructure data for vulnerability assessments.

Strengths

• Provides three distinct flood model scenarios for comparative analysis.
• Data is available in multiple standard geospatial formats (GeoJSON, SHP, WMS) for interoperability.

Limitations

• The dataset's spatial coverage is limited to the Woodend area in Victoria, Australia.
• No metadata on the underlying hydrological model parameters or validation is provided.
