This project plans to improve the monitoring of our waterways by developing a novel moving drifter system that takes flow and water quality measurements along the pathlines of the drifters. One of the key challenges for Australian water management lies in monitoring and managing rivers and estuaries effectively over large geographical areas. Traditionally, instrumentation at stationary points has been used for such monitoring, under the simplifying assumption that a single point adequately represents a very large region of water. By contrast, the Real-Time Flow Logging of Water (RT-FLOW) system expects to provide information from large regions of our waterways, providing stakeholders with more information to enable them to better manage issues including storm surge and erosion. The project also aims to provide improved validation of hydrodynamic models.Read moreRead less

By advancing pollutant transport modelling that use recent developments in drift sensors, this project aims to investigate water quality of estuaries and coastal rivers under pressure from urban growth. The project expects to generate a new capability for quantitative particle concentration predictions through detection and innovative analysis of Lagrangian Coherent Structures. The expected outcome is a new particle transport modelling framework and algorithms for shallow water systems, which effectively exploit extensive datasets becoming available from GPS-enabled drifters. This should provide significant benefits such as reliable assessment of possible effects of catchment and waterway changes on pollutant and sediment concentration which can impact waterway health.Read moreRead less

This project aims to develop and validate fundamental theories and techniques for a novel intelligent wireless access paradigm to enhance the efficiency in frequency usage. This innovative approach will be one of the critical enablers for massive device access necessary for future wireless network evolution to support the growing Internet-of-Things. It will enable co-working devices to autonomously sense the local radio frequency landscape, determining how to avoid interference, and exploiting opportunities to intelligently and efficiently access the available radio resources. This will lead to enhanced efficiency in radio resource usage. The project will significantly improve the efficiency of current radio resource utilisation and offer solutions to a challenge of national significance.Read moreRead less
