Upon the publication of her study of the Goulburn River, Julia Imrie hopes that her seven years of work has provided a valuable resource for the future management of the complex ecosystem that includes The Drip Gorge.
As the title suggests, ‘Changing Land Use in an Uncertain Climate: Impacts on Surface and Groundwater in the Goulburn River NSW’, looks into the effects on the largest tributary to the Hunter River.
It was a collaborative study with Australian National University and NSW Department of Primary Industries – Water (earlier Office of Water), and with a Australian Research Council grant.
“There’s three main areas; climate change, which is creating a lot of variability on top of variability; land use, in this case mining as well as agriculture releasing salts in a salty geology to start with; and the fact that a lot of land use is intercepting the freshwater aquifers,” Dr Imrie
“And it’s looking at the interaction between surface and groundwater and the Goulburn River over time.”
The thesis includes case studies on the Merriwa River and The Drip Gorge.
