ACTGOV Flood Extent Model: Canberra Catchment Risk Maps

ACTmapi compiled the most comprehensive review of Canberra's catchments and flood risk to date. The dataset models a 1% Annual Exceedance Probability flood event for the Australian Capital Territory. It is provided by the ACT Government Geospatial Data Catalogue for public information purposes.

Use Cases

• Model flood risk for property development based on catchment analysis.
• Inform emergency response planning based on riverine flood extent maps.
• Assess insurance risk for properties based on 1% Annual Exceedance Probability flood models.
• Study catchment behavior and floodplain dynamics based on the available modelling.
• Create public awareness materials about flood risk based on the provided floodplain data.

Strengths

• Based on the most comprehensive review of Canberra's catchments to date.
• Models a specific flood event probability (1% Annual Exceedance Probability).
• Available in multiple geospatial formats including CSV, GPKG, and GeoJSON.

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.
