Brisbane Citywide Overland Flow Flood Study Sub-Model Data

27 individual sub-models cover the entire Brisbane City Council area for flood risk management. The dataset contains reports, metadata, and results data for flood height, depth, and hazard across eight storm event recurrence intervals. It was produced by Brisbane City Council and last updated in March 2026.

Use Cases

• Analyze flood height and depth results across the 2 to 2000-year Average Recurrence Interval storm events for specific sub-model locations.
• Assess flood hazard (depth x velocity) data to inform policy and infrastructure planning within the 27 sub-model catchments.
• Cross-reference metadata from the flood study report with results data to understand modeling inputs for the Lower Oxley Sub-Model.
• Map floodplain condition scenarios using the provided sub-model boundaries to identify high-risk zones in Brisbane.

Strengths

• Covers the entire Brisbane City Council area through 27 detailed sub-models.
• Provides results for eight distinct storm event recurrence intervals (2, 5, 10, 20, 50, 100, 500, 2000-year ARI).
• Includes complementary reference materials such as a detailed map and a full flood study report.

Limitations

• The specific row count, column structure, and sample data for the tabular metadata are unavailable, hindering immediate analytical use.
• Primary data format is HTML, which may require extraction and transformation for programmatic analysis.
• Focus is limited to the Brisbane City Council geography, not applicable to other regions.
