dc.description.abstract Although the Great Barrier Reef is recognised as one of the best managed reef systems in the world, coral cover has declined over the last decades at rates similar to less well managed reefs, and research based management and policy is recognised as a pathway for mitigating this trend.Model development to guide management actions is considered a criterion for the effective integration of science and management. Integrated models spanning physical processes through to water quality and ecosystem response are expected to assist regulatory authorities with issues relating to reef management, and to serve as a tool to assist in the evaluation of effectiveness of various management strategies and actions. In this context, the marine modelling component of eReefs was tasked to deliver numerical models capable of simulating and predicting the physical hydrodynamic state, sediment transport, water quality and basal ecology of the Great Barrier Reef lagoon and reef matrix. Together, these models represent a capability to simulate the transport and fate of waterborne material, of either oceanic or terrestrial origin, and its impact on Reef water quality. The numerical models are built using CSIRO's Environmental Modelling Suite, and this report describes the application of that suite to the Great Barrier Reef, including details of regional 4 km and 1 km resolution models, and an automated re-locatable coastal ocean modelling system (RECOM) capable of resolving individual reefs, estuaries and embayments at resolutions of tens to hundreds of metres. For the regional models, the report describes their spatial application and the forcing applied to the model boundaries, as well as specific model developments necessary for their application to the Great Barrier Reef.Model calibration and validation against observations is presented and examples of model application to understand and characterize behavior of a number of bio-physical processes on the GBR are described. RECOM required new development to the Environmental Modelling Suite, and details of this are included along with three case studies demonstrating its use in reef and coastal environments. Detailed in this report, and summarized in the Technical Summary, are highlights of the outputs of modelling products and an assessment of the model performance. The complete model outputs are available through the eReefs information system. Further details of the underlying mechanics of the Environmental Modelling Suite such as numerical methods, are detailed in other published works, which are listed in this report en_AU
