Westport has partnered with the Western Australian Marine Science Institution (WAMSI) to deliver the $13.5 million WAMSI-Westport Marine Science Program. This 3-year program is developing the latest data, information and modelling on the complex environmental systems and community values associated with Cockburn Sound.

Research Theme: Hydrodynamic Modelling

Developing a baseline understanding of hydrodynamics within Cockburn Sound
Due to the complex nature of the bathymetry, natural landforms, wave conditions and man-made changes to the area, Cockburn Sound demonstrates complex and unique hydrodynamics that were examined as part of this project.
By resolving the hydrodynamic and ocean boundary conditions within the area, we allow for the accurate prediction of conditions, like waves, swells, current and tides, within Cockburn Sound. This information is critical for Westport to support the planning and development of the new port, while mitigating impacts on the local marine ecosystem.
To build such models, large datasets are required. This study looked to bring together new and historical data to validate a high-resolution model for Cockburn Sound.
During the field campaign to gather new data, up to 25 sensors were deployed. A review of previous studies and literature was also undertaken to add to the current understanding around waves conditions, water temperature, salinity, and currents within Cockburn Sound.
How Westport will use this report
This data has been used to inform the initial design of the marine infrastructure for the new port, and Westport will be further using the data to support more modelling for the Environmental Impact Assessment.
