Flood Study — Citywide Overland Flow — Moggill East Sub-Model

27 individual sub-models covering the entire Brisbane City Council area provide flood height, depth, and hazard results for storm events with 2 to 2000-year Average Recurrence Intervals. The dataset contains reports, metadata, and results data for existing floodplain conditions from the Brisbane City Council Citywide Creek and Overland Flow Path Mapping Flood Study. Council maintains this data to help manage flood risk and inform policy within the Brisbane River and local creek catchments.

Use Cases

• Model flood risk for specific properties based on flood height and depth data for different storm frequencies.
• Inform land-use planning and development regulations using flood hazard (depth x velocity) maps.
• Calibrate or validate other hydrological models with the technical data from this detailed sub-model study.

Strengths

• Covers the entire Brisbane City Council area through a series of 27 individual sub-models.
• Provides results for eight distinct storm event frequencies, from 2 to 2000-year Average Recurrence Intervals.
• Includes a detailed flood study report and metadata explaining the modelling methodology.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, being specific to Brisbane.
