Fitzroy River Basin Sediment Source Analysis Using Geochemical and Bayesian Modelling

An integrated geochemical and Bayesian modelling approach identified and quantified sediment sources in the Fitzroy River coastal zone. The study found the proportion of basaltic material deposited has increased in recent time, now the dominant catchment source with an estimated enrichment of ca. 3 relative to catchment abundances. This dataset, sourced from the Australian Ocean Data Network, was last updated on 2026-06-16.

Use Cases

• Modeling changes in catchment sediment sources over time based on the Bayesian statistical model described.
• Analyzing the impact of rainfall event variations and land use changes on coastal sediment composition.
• Assessing the enrichment and transport of basaltic soils in freshwater flood plumes to the outer shelf.
• Targeting land management practices to reduce sediment loads from specific source areas.

Strengths

• Analysis reveals a specific enrichment factor of ca. 3 for basaltic material.
• Study integrates geochemical data with a Bayesian statistical modelling approach.
• Findings link sediment source changes to historical events like European settlement and land clearing.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the last update date is in the future (2026-06-16).
