ACTGOV Flood Hazard Model: Canberra Catchment Risk Maps

ACTGOV FLOOD HAZARD MODEL is a geospatial dataset from the ACT Government Geospatial Data Catalogue (ACTmapi). It represents the most comprehensive review of Canberra’s catchments and their associated flood risk to date, modeling a 1% Annual Exceedance Probability (AEP) flood event. The data is provided via ARCGIS GEOSERVICES REST API and HTML formats and was last updated on 2026-04-04.

Use Cases

• Assess property-level flood risk based on modeled 1% AEP flood extents.
• Plan urban development and infrastructure based on catchment flood risk.
• Inform public awareness and emergency preparedness for riverine flooding.
• Support scientific research on flood modeling uncertainties and variables.

Strengths

• Model represents the most comprehensive review of Canberra’s catchments to date.
• Data is derived from the best available modeling of the catchments and watercourses.
• Last updated date is explicitly provided: 2026-04-04 03:07:28.905020.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
• Data does not depict real-time information or historical flood events.
