Model Details

The estuary is simulated using the TUFLOW-FV hydrodynamic model that is dynamically coupled with the AED2 water quality model. The modelling domain spans the full extent of the estuary from Fremantle to Great Northern Highway. The final mesh used was determined from previous grid sensitivity assessment to satisfy model accuracy but also compromise for model runtime ration. In total, 23 state (transportable) variables were simulated from the “aed2_tracer”, “aed2_oxygen”, “aed2_nitrogen”, “aed2_phosphorus”, “aed2_organic_matter”, “aed2_phytoplankton” and “aed2_macrophyte” modules, and 42 diagnostic variables were output. A total of 53 monitoring sites were included in the assessment of model performance, for 14 measured water quality attributes, and where possible surface and bottom values were individually assessed
