Brisbane Citywide Overland Flow Flood Study for 27 Sub-Models

Brisbane City Council's flood study provides results data for 27 sub-models covering the entire city. The dataset contains flood height, depth, and hazard results for storm events with 2 to 2000-year Average Recurrence Intervals. Council uses this technical data to inform flood risk management policy within local creek and overland flow catchments.

Use Cases

• Modeling flood hazard (depth x velocity) for specific locations based on the 27 sub-model structure.
• Assessing flood risk for infrastructure planning using height and depth data for multiple storm recurrence intervals.
• Informing land-use policy and development controls based on the citywide overland flow path mapping.
• Validating or calibrating other hydrological models using the detailed sub-model results provided.

Strengths

• Covers the entire Brisbane City Council area through 27 individual sub-models.
• Provides results for eight distinct storm recurrence intervals, from 2 to 2000 years.
• Includes multiple flood metrics: height, depth, and hazard (depth x velocity).

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, focusing solely on Brisbane.
