Improving water quality modelling by better understanding solute transport

Poor stream water quality is a critical problem in Australia and globally. Stream water quality depends directly onpathways and time taken for water to transport pollutants through catchments. Predicting these pathways is highlychallenging and currently requires specialised data. This project aims to better model the movement of water fromrainfall to streams, enable greatly improved use of water quality data routinely collected in Australia's catchmentsand thereby better predict water quality behaviour. Proposed field studies aim to support this development. Theoutcomes sought are improved planning and management of water quality in our rivers, lakes and estuaries,improved health of these water bodies and improved water supplies.
