Need

Primarily this project is needed to satisfy the regulatory requirements of the Tasmanian salmon industry regulator, the EPA. Currently there is no calibrated local scale model that is suitable to provide connectivity information of the region in question. This proposal aims to develop a nested suite that may provide environmental information to assist in satisfying the salmon farming requirements in the region.

Objectives

1. A calibrated model is developed, where the model skill is known and those connectivity characteristics can be bounded by levels of confidence.

Summary

The study aims to satisfy the regulatory requirements of Environmental Licence 10172/2 from the Tasmanian EPA around Tassal’s use of Okehampton Bay for salmonoid aquaculture, particularly the possible fate of material released within Okehampton Bay into the receiving environment. To achieve that objective, the CSIRO Coastal Environment Modelling team (CEM team) developed a hydrodynamic model to investigate the far field and regional hydrodynamic connectivity around Okehampton Bay and the Mercury Passage surrounds, hereafter referred to as the OKE model.
