Brisbane Flood Study: Overland Flow Paths and Hazard Data for 27 Sub-Models

27 individual sub-models cover the entire Brisbane City Council area for flood risk analysis. The dataset contains results for flood height, depth, and hazard for storm events with recurrence intervals from 2 to 2000 years. Brisbane City Council produced this data to inform flood policy and management.

Use Cases

• Model flood hazard (depth x velocity) based on the described hazard calculation for different storm frequencies.
• Identify overland flow paths for urban development planning based on the flood study's mapping.
• Assess property-level flood risk using the sub-model geospatial data referenced in the description.
• Inform policy on floodplain management based on the technical data from the study.

Strengths

• Covers the entire Brisbane City Council area through 27 integrated sub-models.
• Provides flood data for eight distinct storm recurrence intervals, from 2 to 2000 years.
• Includes multiple flood metrics: height, depth, and a calculated hazard index.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and data scale are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, being specific to Brisbane.
