Brisbane Flood Study: Overland Flow Models for 27 Sub-Catchments

Brisbane City Council's flood study provides technical data for managing flood risk across the entire city. The dataset contains results for flood height, depth, and hazard across 27 individual sub-models for storm events with recurrence intervals from 2 to 2000 years. It was published by Brisbane City Council and includes reports, metadata, and results data for existing floodplain conditions.

Use Cases

• Assess flood hazard (depth x velocity) for specific locations based on the 8 defined storm recurrence intervals.
• Inform land-use policy and development controls using the technical floodplain data.
• Identify overland flow paths within the Inner West and other sub-model catchments.
• Validate or supplement other hydrological models with the council's latest flood modelling data.

Strengths

• Covers the entire Brisbane City Council area through a series of 27 individual sub-models.
• Provides results for 8 distinct storm event recurrence intervals (2, 5, 10, 20, 50, 100, 500, and 2000 year ARI).
• Includes a detailed reference map showing the boundaries of all 27 sub-models.

Limitations

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