Middle Bulimba Flood Model Data for 8 Storm Scenarios

27 sub-models cover the entire Brisbane City Council area, providing flood height, depth, and hazard results for eight Average Recurrence Interval storm events ranging from 2 to 2000 years. Brisbane City Council produced this technical data to inform flood risk management policy for local creek and overland flow catchments.

Use Cases

• Analyze flood height and depth results across the 2, 5, 10, 20, 50, 100, 500, and 2000-year ARI storm events for the Middle Bulimba sub-model.
• Calculate flood hazard (depth x velocity) for specific locations within the Middle Bulimba catchment using the provided model results.
• Compare floodplain condition scenarios for the existing environment using the study's reports and metadata.
• Identify the relevant sub-model for a location of interest among the 27 individual sub-models covering Brisbane.

Strengths

• Covers eight distinct storm event probabilities (2 to 2000-year ARI), enabling multi-scenario risk assessment.
• Part of a citywide study comprising 27 individual sub-models for comprehensive spatial coverage of Brisbane.
• Includes results for three key flood metrics: height, depth, and hazard (depth x velocity).

Limitations

• Data format is primarily HTML, which is not structured for direct machine learning or automated analysis without significant extraction.
• Sample data and specific column schema are unavailable, obscuring the exact data structure and variables.
• Relies on a separate reference dataset for critical context like the study report and sub-model map, requiring users to locate and join multiple resources.
