Brisbane Citywide Overland Flow Flood Study: Kholo Sub-Model

Brisbane City Council's Citywide Creek and Overland Flow Path Mapping Flood Study comprises 27 sub-models covering the entire council area. The Kholo Sub-Model dataset contains reports, metadata, and results data for flood height, depth, and hazard for storm events with 2 to 2000-year Average Recurrence Intervals. This data is used to inform flood risk management policy and practices within the Brisbane River and local creek catchments.

Use Cases

• Modeling flood inundation extents based on the described flood height and depth results for different storm frequencies.
• Assessing flood hazard (depth x velocity) for specific locations using the sub-model results data.
• Informing land-use planning and development controls based on the overland flow path mapping.
• Validating or calibrating other hydrological models using the technical data and methodology from the flood study report.

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-year to 2000-year Average Recurrence Intervals.
• Includes accompanying study reports and metadata that document the modelling methodology.

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.
• The primary data format listed is HTML, which may not be optimal for direct geospatial analysis.
