Camden Haven Flood Study Update with Hydrologic and Hydraulic Models

An updated flood study for the Camden Haven Valley in Australia, initiated after the March 2021 extreme weather event. Port Macquarie-Hastings Council used post-event data to validate and refine 2013 flood models, producing new flood maps for major tributaries and estuarine areas. The final report was adopted in February 2026.

Use Cases

• Validate flood risk models based on the 2021 extreme weather event data mentioned in the description
• Update flood hazard maps for land-use planning based on revised flood levels and flow velocities
• Calibrate hydrologic models for the catchment using the newly developed model detailed in the report

Strengths

• Model validation uses data from a specific 2021 extreme weather event
• Results are aligned with Australian Rainfall and Runoff 2019 procedures
• License is CC-BY-4.0, allowing for broad reuse

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
