Development and use of GPS-based technology to study dispersion in shallow water

This project was a step forward for the measurement and management of shallow water estuaries using satellite technology. Newly developed Global Positioning System (GPS) high resolution drifters were used to investigate the flow field and the spreading behaviours of passive particles. It identified the dominant mechanisms responsible for the tidal scale spreading with a focus on tidal estuaries in Southeast Queensland. Importantly, this study provides a unique moving sensor (Lagrangian) approach to strengthen current modelling efforts in prediction of the transport of materials in tidal estuaries. This new approach provides a unique complement to the traditional fixed sensor (Eulerian) approach
