Flood Study — Citywide Overland Flow — Cabbage Tree Sub-Model

Brisbane City Council's Citywide Creek and Overland Flow Path Mapping Flood Study comprises 27 individual sub-models covering the entire council area. Results data for flood height, depth, and hazard are available for storm events with recurrence intervals from 2 to 2000 years. The dataset contains reports, metadata, and results data for existing floodplain condition scenarios.

Use Cases

• Assess flood risk for property development based on modeled flood height and depth data.
• Inform urban planning and policy using technical flood study results for various storm recurrence intervals.
• Validate or calibrate other hydrological models using the detailed sub-model data for the Cabbage Tree catchment.

Strengths

• Covers the entire Brisbane City Council area through a series of 27 sub-models.
• Provides results for eight distinct storm recurrence intervals, from 2 to 2000 years.
• Includes associated flood study reports and metadata for context.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and data scale are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Brisbane City Council area.
