Brisbane Citywide Overland Flow Flood Study for Middle Bulimba Sub-Model

A 2026 flood study by Brisbane City Council provides results data for the Middle Bulimba sub-model, one of 27 covering the entire council area. The dataset contains flood height, depth, and hazard results for storm events with Average Recurrence Intervals of 2 to 2000 years. It is part of the Citywide Creek and Overland Flow Path Mapping Flood Study to inform flood risk management policy.

Use Cases

• Modeling flood hazard (depth x velocity) for specific storm recurrence intervals based on the described results data.
• Informing land-use and development policy based on the technical floodplain condition scenarios.
• Identifying overland flow paths and flood extents for the Middle Bulimba catchment area.
• Integrating sub-model results into broader citywide flood risk assessments as part of the 27-model study.

Strengths

• Covers 27 individual sub-models for the entire Brisbane City Council area, providing comprehensive spatial coverage.
• Includes results for 8 distinct storm event frequencies (2, 5, 10, 20, 50, 100, 500, and 2000-year ARI).
• Provides multiple flood metrics: height, depth, and hazard (depth x velocity) for analysis.
• Associated study report and metadata are available in the related 'reference' dataset for context.

Limitations

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