NESP TWQ Project 1.7: Alluvial Gully Erosion Management Effectiveness, 2015-2016

Alluvial gully erosion contributes 20-40% of fine sediment from the three largest sediment contributing catchments to the Great Barrier Reef. The project evaluates the effectiveness of different management strategies to reduce this erosion, collecting baseline data in the Normanby and Burdekin catchments. Data is hosted by the Australian Ocean Data Network and was last updated in July 2026.

Use Cases

• Evaluate erosion management strategy effectiveness based on data collected after Cyclone Ita.
• Model sediment source contributions based on the described 20-40% fine sediment figure.
• Establish baseline erosion rates for alluvial gullies based on data from the Normanby and Burdekin catchments.

Strengths

• Focuses on a major sediment source contributing 20-40% of fine sediment to the Great Barrier Reef.
• Leverages a 'natural experiment' from Cyclone Ita to test management strategies.
• Data collection spans multiple sites in the Normanby and Burdekin catchments.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• File formats include PNG and HTML, suggesting the primary data may be reports or images rather than structured tables.
