Keppel Bay Sediment Transport Dynamics and Seabed Morphology

Geoscience Australia Data characterizes sediment transport in Keppel Bay, a macrotidal embayment linking the Fitzroy River to the Great Barrier Reef shelf. Analysis of seabed samples, shear-stress modeling, and three-dimensional acoustic imaging reveals a mixed wave- and tide-dominated system with active tidal sand ridges and subaqueous dunes. The dataset, last updated in 2026, provides a detailed example of the physiography of a tide-dominated estuarine system.

Use Cases

• Modeling sediment transport pathways based on shear-stress modeling and acoustic imaging data.
• Analyzing seabed morphology based on the characterization of tidal sand ridges and subaqueous dunes.
• Assessing the impact of hydrodynamic regimes on coastal infilling based on the described transport patterns.
• Studying the interaction between riverine sediment loads and reef shelf environments based on the system's role as a conduit.

Strengths

• Analysis integrates multiple data sources: seabed samples, shear-stress modeling, and 3D acoustic imaging.
• Provides a detailed characterization of a specific, complex macrotidal estuarine system.
• Dataset is hosted by Geoscience Australia Data, a national geological survey.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the single study location.
