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. In this project, high-fidelity computational and experimental techniq ....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. 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
Quantifying the effects of criteria air pollutants on child health - setting Australian air quality standards. The project is proposed and supported by the National Environment and Heritage Protection Council, who will be reviewing Australian air quality standards from 2005. The study aims to determine whether current air quality standards adequately protect the health of Australian school children, and to provide nationally-based information to inform any changes to the current standards. A cr ....Quantifying the effects of criteria air pollutants on child health - setting Australian air quality standards. The project is proposed and supported by the National Environment and Heritage Protection Council, who will be reviewing Australian air quality standards from 2005. The study aims to determine whether current air quality standards adequately protect the health of Australian school children, and to provide nationally-based information to inform any changes to the current standards. A cross-sectional study will examine cumulative effects; a nested panel study will quantify day-to-day effects of air pollution in sensitive children. Sampling will ensure national representation and generalisability of findings. This will be the first nationally-based study of the relationship between air quality and child health in Australia.Read moreRead less
