Flood Study — Citywide Overland Flow — Daguilar Sub-Model: Brisbane Flood Hazard Data

27 individual sub-models cover the entire Brisbane City Council area for flood risk management. Results data for flood height, depth, and hazard are available for storm events with recurrence intervals from 2 to 2000 years. Brisbane City Council produced this dataset as part of its Citywide Creek and Overland Flow Path Mapping Flood Study.

Use Cases

• Assess flood risk for specific properties based on flood height and depth results for different storm frequencies.
• Model overland flow paths for urban planning and infrastructure development in the Daguilar sub-model area.
• Analyze flood hazard (depth x velocity) to inform emergency response and land-use policy.
• Integrate sub-model results into broader hydrological studies of the Brisbane River and local creek catchments.

Strengths

• Covers the entire Brisbane City Council area through a series of 27 sub-models.
• Provides results for eight distinct storm event frequencies, from 2 to 2000-year Average Recurrence Intervals.
• Includes multiple flood metrics: height, depth, and hazard (depth x velocity).

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.
