NESP MaC Project 3.4: Catchment Runoff Impact Models for Northern Australia, 2023-2024

A 2023-2024 study by the NESP Marine and Coastal Hub provides data to improve management of catchment runoff impacts on marine environments in northern Australia. Planned outputs include river plume modelling datasets, sediment and chlorophyll load estimates, mangrove extents from remote sensing, and experimental data on primary production. The project leverages existing development examples, such as in the Lower Burdekin Delta near the Great Barrier Reef, to create a template for decision-makers.

Use Cases

• Modeling sediment and chlorophyll loads from river plumes based on the planned modelling dataset.
• Mapping mangrove habitat extents based on the remote sensing dataset.
• Assessing the impact of irrigation and grazing development on coastal water quality based on the project's experimental and modelling data.
• Informing catchment management policy based on the final technical report's analyzed data and recommendations.

Strengths

• Project leverages specific, real-world case studies, such as the Lower Burdekin Delta, to inform models.
• Planned outputs include multiple data types: spatial modelling, remote sensing, and experimental datasets.
• Last metadata update was 2026-06-17, suggesting ongoing curation.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The specific data outputs are in child records, requiring additional navigation to access.
