ACTGOV Flood Depth Model: Canberra Catchment Flood Risk

A flood depth model for Canberra's catchments represents the most comprehensive review of flood risk in the Australian Capital Territory to date. It was compiled by the ACT Government using the best available modelling resources and is provided via an ArcGIS REST API. The model focuses on a 1% Annual Exceedance Probability (AEP) flood event.

Use Cases

• Model flood inundation extent based on the 1% AEP flood depth data.
• Assess property-level flood risk for urban planning decisions.
• Support emergency response planning for riverine flooding scenarios.
• Inform public awareness and education about flood hazards in Canberra.

Strengths

• Represents the most comprehensive review of Canberra's catchment flood risk to date.
• Based on national best practice flood risk management standards.
• Modeled for a specific flood probability (1% Annual Exceedance Probability).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data does not depict real-time information or historical flood events.
