Flood Study — Citywide Overland Flow — Wolston Sandy Sub-Model: Brisbane Flood Data

Brisbane City Council's Citywide Creek and Overland Flow Path Mapping Flood Study comprises 27 sub-models covering the entire council area. The Wolston Sandy Sub-Model dataset contains reports, metadata, and results data for flood height, depth, and hazard under various storm event scenarios. Results are provided for 2, 5, 10, 20, 50, 100, 500, and 2000-year Average Recurrence Interval storm events.

Use Cases

• Modeling flood risk for property development based on flood height and depth data.
• Informing flood policy and catchment management based on overland flow path mapping.
• Assessing flood hazard (depth x velocity) for emergency planning across different storm recurrence intervals.

Strengths

• Covers the entire Brisbane City Council area through a series of 27 individual sub-models.
• Provides results for eight distinct storm event scenarios, from 2-year to 2000-year Average Recurrence Intervals.
• Includes a detailed flood study report and metadata describing the modelling methodology.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, being specific to Brisbane.
