Numerical modelling of Macquarie Harbour

TL;DRAbstract

Tiris thesis is about the creation of a numerical model and its application to Macquarie Harbour (Tasmania, Australia). With the aim being to better understand the harbour and aid the management of its environment and industry. A numerical model was developed through the combination of an original two-dimensional laterally averaged river model and an existing three-dimensional ocean model. The existing three-dimensional model used is the Princeton Oceanographic Model (POM) by Blumberg and Mellor (1987), which is used for modelling the harbour. The author's river model is used for the two main rivers flowing into Macquarie Harbour, and part of the ocean surrounding the harbour. The river model is based on non-Boussinesq primitive equations, which include the density terms neglected in the commonly used Boussinesq approximation. These density terms are important where there are large salinity stratifications, which occur in the rivers flowing into Macquarie Harbour. The primitive equatio
