Flood Study — Citywide Overland Flow — Nundah Sub-Model

27 individual sub-models cover the entire Brisbane City Council area. This dataset contains reports, data, metadata, and results for existing floodplain condition scenarios from the Citywide Creek and Overland Flow Path Mapping Flood Study. Brisbane City Council provides this technical data to help manage flood risk and inform policy for the Brisbane River and local creek catchments.

Use Cases

• Model flood risk for properties based on flood height, depth, and hazard data for different storm events.
• Inform urban development policy based on technical flood study results for existing conditions.
• Identify overland flow paths within the Nundah sub-model catchment area.
• Assess flood hazard (depth x velocity) for 2 to 2000-year Average Recurrence Interval storm scenarios.

Strengths

• Covers the entire Brisbane City Council area through 27 sub-models.
• Provides results for eight distinct storm event frequencies (2, 5, 10, 20, 50, 100, 500, 2000-year ARI).
• Includes accompanying study reports and metadata for context.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and specific data volume are unknown, which may limit suitability assessment.
• Data freshness should be verified despite the listed future update date of 2026-06-28.
