Brisbane Airport Sub-Model Flood Height and Hazard Data

Brisbane City Council's Citywide Creek and Overland Flow Path Mapping Flood Study includes 27 individual sub-models covering the entire council area. This Airport Sub-Model provides results data for flood height, depth, and hazard for storm events with recurrence intervals from 2 to 2000 years. The dataset contains reports, metadata, and modeling data used to inform flood risk management policy.

Use Cases

• Model flood hazard (depth x velocity) for the 2-year to 2000-year Average Recurrence Interval storm events in the airport catchment.
• Analyze spatial patterns of flood height and depth results from the existing condition scenarios.
• Integrate this sub-model's data with the other 26 sub-models for citywide floodplain mapping and risk assessment.

Strengths

• Covers the entire Brisbane City Council area through a series of 27 individual sub-models.
• Provides results for eight distinct storm event frequencies (2, 5, 10, 20, 50, 100, 500, 2000-year ARI).
• Includes three key flood metrics: height, depth, and hazard (depth x velocity).

Limitations

• Data format is HTML, which is not ideal for direct programmatic analysis and requires extraction.
• Sample data and column structure are unavailable, complicating assessment of data structure and usability.
• Relies on a separate reference dataset for critical metadata and sub-model boundaries, requiring a join.
