Brisbane Flood Study Overland Flow Model Results and Metadata

Brisbane City Council's Citywide Creek and Overland Flow Path Mapping Flood Study includes 27 individual sub-models covering the entire council area. The dataset provides flood height, depth, and hazard results for eight Average Recurrence Interval storm events from 2 to 2000 years. It contains reports, metadata, and results data for existing floodplain condition scenarios.

Use Cases

• Analyze flood height and depth results across the eight ARI storm events to assess risk for specific locations.
• Map flood hazard (depth x velocity) data from the 27 sub-models to identify high-risk zones within Brisbane.
• Use the flood study metadata to understand the modeling inputs and assumptions for policy development.
• Compare existing floodplain condition scenarios across different sub-model catchments for infrastructure planning.

Strengths

• Covers the entire Brisbane City Council area through 27 detailed sub-models.
• Provides results for eight distinct storm recurrence intervals (2, 5, 10, 20, 50, 100, 500, 2000 year ARI).
• Includes multiple data types: flood height, depth, hazard calculations, reports, and modeling metadata.

Limitations

• The data format is primarily HTML, which is not ideal for direct programmatic analysis and requires extraction.
• Specific technical details and data usage guidelines require reading the separate flood study report.
• Sample data and structural details like row/column counts are not provided in the input.
