Thermal stratification, overturning and mixing in riverine environments. Thermal stratification is common in Australia's rivers due to our hot, drought-prone climate and high human demands relative to available supply, which has led to a significant reduction in flows relative to natural levels. Thermal stratification inhibits mixing, creating stagnant conditions characterised by low oxygen levels and increased concentrations of contaminants, leading to algal blooms, fish kills and systemic dama ....Thermal stratification, overturning and mixing in riverine environments. Thermal stratification is common in Australia's rivers due to our hot, drought-prone climate and high human demands relative to available supply, which has led to a significant reduction in flows relative to natural levels. Thermal stratification inhibits mixing, creating stagnant conditions characterised by low oxygen levels and increased concentrations of contaminants, leading to algal blooms, fish kills and systemic damage to ecosystems. The aim of this project is to develop predictive models for the effects of physical processes such as night-time cooling, wind, turbulence and currents on riverine thermal stratification. This is expected to enable a more accurate determination of the flow rates required to maintain the health of our river systems.Read moreRead less

In-situ Structural Health Monitoring (SHM) is part of a current revolution in smart-structures technologies promising quantum gains in performance, endurance and cost-efficient maintenance for high-value assets. The aim of the proposed network is to provide a platform for collaborative, multidisciplinary research, research training and innovation by integrating currently disparate programs in SHM, since the high investment costs for the development of next generation smart technologies make a collaborative approach an absolute necessity. Its significance includes the efficient generation of world-class research outcomes in the key technologies enabling this revolution, viz. (i) sensor technologies; (ii) multifunctional materials; and (iii) intelligent systems, and the timely dissemination of these outcomes to Australian industry.Read moreRead less
