Superseded Hydrodynamic Model of the Great Barrier Reef

A collection of results from version 1.85 of a 4 km resolution hydrodynamic model for the Great Barrier Reef. The model was forced with ocean boundary data from BlueLink OceanMAPS and atmospheric data from ACCESS-R, incorporating 22 tidal constituents and 22 river boundaries. It was published for reference in 2016 but contains known salinity errors due to incorrect rainfall forcing.

Use Cases

• Analyze hydrodynamic patterns using the 4 km resolution model output for the Great Barrier Reef region.
• Investigate the impact of 22 incorporated river boundaries on regional salinity and temperature fields.
• Study tidal influences using the 22 tidal constituents derived from the global CSR tide model.
• Compare superseded model results (GBR4_H1p85) with newer versions to assess error correction in rainfall forcing.

Strengths

• Model output at a 4 km spatial resolution for detailed regional analysis.
• Incorporates data from 22 river boundaries and 22 tidal constituents for comprehensive forcing.
• Published for reference in a 2016 SIEF report, providing a documented baseline.

Limitations

• Dataset is superseded and contains known salinity errors due to incorrect rainfall forcing.
• Access is restricted to an archive copy available only upon request from custodians.
• Temporal coverage and specific data volume (rows, size) are not specified.
