Bald Hills Sub-Model Flood Height And Hazard Data

Brisbane City Council's flood study provides results data for the Bald Hills sub-model, one of 27 covering the entire council area. The dataset contains modeled flood height, depth, and hazard metrics for storm events with recurrence intervals from 2 to 2000 years.

Use Cases

• Model flood hazard (depth x velocity) for specific locations within the Bald Hills catchment across eight Average Recurrence Interval (ARI) storm events.
• Analyze flood height and depth results to assess property-level risk for the 2, 5, 10, 20, 50, 100, 500, and 2000-year ARI scenarios.
• Integrate sub-model flood height data with spatial planning tools to inform development policy and flood risk management.
• Compare flood depth outputs across the 27 individual sub-models to identify regional vulnerability patterns within Brisbane.

Strengths

• Covers eight distinct storm event frequencies (2 to 2000-year ARI), providing a broad risk assessment spectrum.
• Part of a comprehensive citywide study comprising 27 sub-models for full Brisbane City Council area coverage.
• Data is produced by the local government authority (Brisbane City Council) for official flood risk management.

Limitations

• The dataset appears to be primarily metadata and reports; core flood modeling raster/vector results may be in separate, linked files.
• Specific technical details and model assumptions require reading the separate flood study report, adding a prerequisite for correct use.
• Data format is listed as HTML, which is not ideal for direct programmatic analysis of geospatial or tabular results.
