Witton Creek Flood Study Reports and Metadata

2023 flood study for Witton Creek in Brisbane, containing technical reports, data, and metadata for existing and ultimate floodplain scenarios. The dataset includes linked PDF reports and metadata covering all attachments used for flood modelling. Brisbane City Council produced this study to inform flood risk management policy.

Use Cases

• Analyze flood study report findings from the linked 2023 PDF volumes to understand catchment-specific flood risks.
• Extract metadata describing flood modelling attachments to catalog technical inputs for hydrological models.
• Cross-reference floodplain condition scenarios (existing and ultimate) with catchment area maps for land-use planning.
• Use creek centreline and catchment locality data from the study for geographic information system (GIS) analysis of flood pathways.

Strengths

• Includes the complete 2023 Witton Creek Flood Study reports in two volumes.
• Metadata covers all dataset attachments and linked reports, providing traceability.
• Produced by Brisbane City Council, an authoritative local government source for flood data.

Limitations

• Core modelling data (e.g., raster layers, shapefiles) is not directly provided as rows/columns, limiting quantitative analysis.
• Data format is primarily HTML and linked PDFs, requiring manual extraction for structured use.
• Specific temporal or geographic granularity of the underlying model data is not detailed in the provided description.
