Results from version 2.0 of the 4km-resolution regional-scale hydrodynamic model of the Great Barrier Reef (GBR4). This model was forced with BlueLink Ocean Modelling and Prediction System (OceanMAPS) model results on the ocean boundaries and Bureau of Meteorology ACCESS-R model for surface atmospheric data. The tide was introduced through 22 constituents derived from the global CSR tide model, and the river boundaries incorporate measured stream flow and temperature data from QLD DNRM's gauging stations for 22 rivers, and estimated flows and loads for 49 additional rivers. There were no known forcing problems.

This model configuration and associated results dataset may be referred to as "GBR4_H2p0" according to the eReefs simulation naming protocol.

The model ran in near-real-time mode, updating daily, until January 2024 when the 2023/24 monsoon season caused damage to sensors in the catchments, and we lost access to the critical river-flow forcing dataset.
