eReefs GBR4 Hydrodynamics v4.0: 4km Great Barrier Reef Model Results

Version 4.0 of the 4km-resolution regional-scale hydrodynamic model for the Great Barrier Reef, forced with high-resolution atmospheric, ocean, tide, and river boundary data. This hindcast model, named GBR4_H4p0_ABARRAr2_OBRAN2020_FG2Gv3_Dhnd, succeeded the GBR4_H2p0 model as the best available eReefs hydrodynamic results for its timespan. The dataset is hosted by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Validate and calibrate other oceanographic models based on the high-resolution 4km regional-scale results.
• Study the impact of river discharge on reef ecosystems based on the 64 measured river boundaries.
• Analyze tidal and atmospheric forcing effects on currents using the integrated TPXO and BARRA/BARRA-R2 data.
• Conduct hindcast climate impact assessments for the Great Barrier Reef based on the complete model run.

Strengths

• Model is forced with high-quality, assimilated boundary data from BARRA-R2, BRAN2020, TPXO, and catchment models.
• Provides a 4km spatial resolution, offering detailed regional-scale coverage of the Great Barrier Reef.
• Succeeds the GBR4_H2p0 model as the best available eReefs hydrodynamic results for its timespan.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the specific model configuration and forcing data.
