Brisbane Flood Study Overland Flow Model for Norman Sub-Model

Brisbane City Council provides data and metadata from its Citywide Creek and Overland Flow Path Mapping Flood Study, comprising 27 individual sub-models. The Norman Sub-Model dataset contains results for flood height, depth, and hazard across eight storm event recurrence intervals from 2 to 2000 years.

Use Cases

• Map flood height and depth for the Norman sub-model across 2, 5, 10, 20, 50, 100, 500, and 2000-year storm events to assess local risk.
• Calculate flood hazard (depth x velocity) values for specific locations within the Norman sub-model to inform emergency planning.
• Integrate metadata on flood modelling inputs for the Norman area with results from the other 26 sub-models for citywide analysis.

Strengths

• Covers eight distinct storm event recurrence intervals (2, 5, 10, 20, 50, 100, 500, and 2000-year ARI) for scenario analysis.
• Part of a citywide study composed of 27 individual sub-models covering the entire Brisbane City Council area.
• Includes multiple flood result types: height, depth, and hazard (depth x velocity).

Limitations

• Specific row count, column structure, and sample data are unavailable, hindering immediate technical assessment.
• Primary data format is HTML, which is not ideal for direct programmatic analysis and may require extraction.
• As a sub-model, analysis is limited to a specific geographic segment of Brisbane unless combined with other sub-model data.
