Sediment Mobility Model Outputs for Torres Strait and Gulf of Papua

A hydrodynamic model adapted for the Torres Strait-Gulf of Papua region at 0.051-degree resolution investigates sediment dispersal pathways. The model, validated against current meter data and tidal sea levels, analyzes sediment mobility due to currents, waves, and their interactions across Trade and Monsoon seasons. Sediment input into Torres Strait is approximately 10% greater during the Trade season.

Use Cases

• Compare sediment mobility patterns driven by wave motion versus tidal currents between the Gulf of Papua and Torres Strait regions.
• Analyze seasonal variation in sediment input using model outputs for the Trade and Monsoon seasons.
• Validate hydrodynamic model predictions against observed current meter data and calculated tidal sea levels.
• Investigate dispersal pathways of sediments from the Fly River and northern Great Barrier Reef resuspension events.

Strengths

• Model outputs are validated against observed current meter data and tidal sea levels.
• Analysis covers two distinct seasons (Trade and Monsoon) for comparative study.
• Spatial resolution of the hydrodynamic model is specified as 0.051 degrees.

Limitations

• The dataset is described in an HTML document, not a structured tabular or raster format for direct analysis.
• Sample data and specific column names or variable outputs are unavailable for review.
• The raw data files from the MECO model are not directly accessible, limiting computational reproducibility.
