Flood Height, Depth, and Hazard Data for Brisbane Sub-Models

27 individual sub-models cover the entire Brisbane City Council area for flood risk analysis. Results include flood height, depth, and hazard data for eight storm events ranging from 2 to 2000-year Average Recurrence Intervals. The dataset, produced by Brisbane City Council, contains reports, metadata, and modeling results for existing floodplain conditions.

Use Cases

• Model flood hazard (depth x velocity) across 27 sub-models for different storm recurrence intervals.
• Analyze spatial patterns of flood height and depth data to identify high-risk zones within Brisbane.
• Cross-reference sub-model results with the detailed reference map to assess location-specific flood risk.
• Use metadata on data sources and modeling methods to validate or reproduce flood study findings.

Strengths

• Covers the entire Brisbane City Council area through 27 detailed sub-models.
• Provides results for eight distinct storm event frequencies, from 2 to 2000-year ARI.
• Includes three key flood metrics: height, depth, and hazard (depth x velocity).
• Supported by a published flood study report and a reference map detailing sub-model boundaries.

Limitations

• Data format is primarily HTML, which is not ideal for direct programmatic analysis and requires extraction.
• The dataset focuses on existing conditions and may not include future climate or land-use change scenarios.
• Specific technical details and assumptions are contained in a separate report, requiring additional review for proper use.
