Middle Harbour Northern Catchments Flood Characteristics for Design Floods

Spatial layers from Ku-Ring-Gai Council detail flood characteristics for design floods ranging from a 20% Annual Exceedance Probability to the Probable Maximum Flood. The dataset is hosted on data.gov.au and was last updated in May 2026. It provides flood map outputs for the Middle Harbour Northern Catchments area.

Use Cases

• Model flood inundation extent based on spatial layers for different flood probabilities.
• Assess flood risk for urban development based on flood characteristics for design floods.
• Plan flood mitigation infrastructure based on outputs from the Probable Maximum Flood scenario.

Strengths

• Covers a wide range of flood probabilities from 20% AEP to PMF.
• Spatial data is provided, enabling geographic analysis.
• Last updated in May 2026, suggesting recent maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to its specific catchment area.
