Gravity Current Driven Smoke Dispersion In a Stratified Ambient. Smoke from bushfires transported by gravity currents, and known to occur nationwide, caused the shutdown of businesses, education and events in Canberra in 2019. Recent scientific investigations have shown that the speed of propagation and concentration of smoke in these three-dimensional gravity currents have a long term ‘memory’ of their initial configuration.

Smoke from bushfires transported by gravity currents, and known to occur nationwide, caused the shutdown of businesses, education and events in Canberra in 2019. Recent scientific investigations have shown that the speed of propagation and concentration of smoke in these three-dimensional gravity currents have a long term ‘memory’ of their initial configuration. In this project, high-fidelity computational and experimental techniques will be used to elucidate the fundamental mechanisms of gravity current entrainment and propagation. This knowledge will set a strong foundation to improve operational forecasts of smoke transport that will allow government agencies to better respond to the negative impact of these complicated flows.Read moreRead less

This project aims to tackle a critical challenge of groundwater management – to understand and predict the impacts of declining groundwater levels. Over pumping and declining groundwater tables are a global problem, yet the effects on the ecosystems that exist within aquifers are poorly known. This project will create a world first evidence-based model of how lowering water tables affects the microbes, invertebrates (stygofauna) and ecological processes in groundwater ecosystems, and will demonstrate the consequences of such changes to groundwater quality and availability. This model will allow impacts to be reliably forecast and avoided or mitigated, vastly improving how major developments affecting groundwater are planned and implemented.Read moreRead less
