Brisbane Flood Study Central Sub-Model Overland Flow Data

Flood study results from Brisbane City Council's citywide overland flow mapping project, comprising one of 27 individual sub-models. It contains data for flood height, depth, and hazard across eight storm recurrence intervals from 2 to 2000 years. The study provides technical data for flood risk management within the Brisbane River and local catchment areas.

Use Cases

• Model flood hazard (depth x velocity) for specific locations using results from the Central Sub-Model.
• Analyze flood height and depth variations across eight Average Recurrence Interval storm events (2 to 2000 years).
• Integrate this sub-model's data with the other 26 sub-models for a complete citywide flood risk assessment.
• Use flood study metadata to understand the modeling inputs and assumptions for the Central Sub-Model area.

Strengths

• Covers eight distinct storm recurrence intervals (2, 5, 10, 20, 50, 100, 500, 2000 year ARI).
• Part of a larger study comprising 27 sub-models covering the entire Brisbane City Council area.
• Includes multiple flood metrics: height, depth, and hazard (depth x velocity).

Limitations

• Data format is HTML, which is not structured for direct analysis and requires significant extraction.
• Specific data volume (rows, file size) and column structure are not provided in the metadata.
• Understanding requires consulting separate reference reports, adding complexity to immediate use.
