Flood Modeling Metadata for Brisbane Overland Flow Sub-Model

27 individual sub-models cover the entire Brisbane City Council area for flood risk analysis. This dataset contains metadata, reports, and results data for the Moggill East sub-model, including flood height, depth, and hazard for 8 different storm recurrence intervals. It was produced by Brisbane City Council to inform flood management policy.

Use Cases

• Cross-reference flood hazard (depth x velocity) results for the 2 to 2000-year storm events within the Moggill East sub-model.
• Analyze the spatial coverage of the 27 sub-models to identify adjacent flood study areas for a location of interest.
• Use the provided metadata to understand the data inputs and assumptions behind the flood height and depth modeling.
• Link this sub-model data to the broader Citywide Creek and Overland Flow Path Mapping Flood Study report for methodological context.

Strengths

• Covers the entire Brisbane City Council area through a series of 27 individual sub-models.
• Provides results for 8 distinct storm event scenarios, from 2 to 2000-year Average Recurrence Intervals.
• Includes three key flood metrics: height, depth, and hazard (depth x velocity) for analysis.

Limitations

• The dataset appears to be primarily metadata and documentation; specific tabular data rows and columns are not described.
• Core modeling results (e.g., spatial flood extents) are likely in separate files or formats not detailed here.
• Understanding requires reading the companion flood study report, adding a prerequisite step for effective use.
