The Goulburn is the largest tributary of the Hunter River, an important highly connected surface-groundwater system in eastern Australia. Major land use change over the last 10 years has seen a rapid expansion of mining and rising trend in salt loads. This research has identified crucial differences in the hydrogeology of key tributaries to the Goulburn River and their relative influence on surface and groundwater hydrochemistry. Understanding the complex surface-groundwater interactions in this catchment, its vulnerability to climate extremes and the cumulative influence of mining, is crucial for maintaining the resilience and health of the river and groundwater- dependent ecosystems.
About the speaker
Julia completed her first degree in science at Macquarie University in 1985 and a Graduate Diploma in Water Resources in 2010, studying as an external student. She has worked in natural resource management and as an environmental science teacher for over 25 years and was a board member of the Hunter-Central Rivers Catchment Management Authority between 2004 and 2013. This role involved the strategic planning and evaluation of environmental conservation and rehabilitation projects across the Hunter Valley and Goulburn catchment. Julia lives with her husband on the upper reaches of the Goulburn River where her PhD is based. Her research forms part of a linkage project between ANU and the NSW DPI Water.
