Brisbane Citywide Overland Flow Flood Study: Central Sub-Model Results

Brisbane City Council's flood study contains reports, data, and results for existing floodplain conditions in the central sub-model area. The citywide study comprises 27 individual sub-models covering the entire Brisbane City Council area. Results data for flood height, depth, and hazard are available for storm events with 2 to 2000 year Average Recurrence Intervals.

Use Cases

• Model flood hazard (depth x velocity) for specific locations based on the 27 sub-model structure.
• Assess flood risk for property development using the provided flood height and depth results for various storm frequencies.
• Inform local flood policy and catchment management using the technical data from the study.
• Identify overland flow paths within the Brisbane River and local creek catchments.

Strengths

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

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified as the last update is listed as 2026-06-28.
