Lower Bulimba Flood Model Data for Eight Storm Recurrence Intervals

Flood modeling results for the Lower Bulimba sub-model contain data for flood height, depth, and hazard across eight Average Recurrence Interval storm events. Brisbane City Council produced this dataset as part of a citywide study comprising 27 sub-models to manage flood risk.

Use Cases

• Analyze flood hazard (depth x velocity) values across eight ARI storm events to map risk severity zones.
• Compare flood height and depth results for the 2-year and 2000-year ARI scenarios to assess extreme event impacts.
• Integrate this sub-model's data with the other 26 sub-models for a comprehensive citywide floodplain condition assessment.

Strengths

• Results are provided for eight specific storm recurrence intervals (2, 5, 10, 20, 50, 100, 500, 2000 year ARI).
• Data is part of a systematic citywide study covering the entire Brisbane City Council area via 27 sub-models.
• Includes multiple flood metrics: height, depth, and calculated hazard (depth x velocity).

Limitations

• Data is specific to one of 27 sub-models, requiring integration with others for a complete city picture.
• The dataset appears to be metadata about the modeling inputs, not the direct spatial results or raw model outputs.
• Understanding requires consulting the separate flood study report for methodology and coverage details.
