Groundwater level monitoring data recovered at the end of 2019 from Mystery Road at Breeza on the Liverpool Plains reveals a direct connection between the Gunnedah Formation unconsolidated sands and gravels and the underlying Permian coal measures. The connection is provided by the old deep channel of the Mooki River that cuts down into the coal measures. This is a crucial piece of evidence to be incorporated into groundwater models.
What are the effects of fire on water underground? Let’s think about what happens on the surface, and translate that to what is likely to happen to the subsurface.
The effects of tidal forces on groundwater might be less apparent to us than their effects on the ocean, but they’re just as important.
Dr Oliver Knox has brought together information from some of the industry’s researchers conducting work oncotton-producing soils.
Groundwater research at ANSTO has provided crucial information to support the management of finite groundwater resources appropriately and sustainably—answering questions about groundwater recharge, groundwater age and dynamics, the interaction between surface water and groundwater and salinisation.
Astonishing footage of a river in Queensland on fire has once again stoked the coal seam gas (CSG) debate.
Groundwater is the largest active freshwater resource on the planet.
As cave deposits grow, they lock into their minerals the chemical signatures of the environmental and climatic conditions of the time the rainwater fell at the surface.
Before we conducted our research, we simply didn’t know much about the deep groundwater system in Sydney Basin. With our new record, this means that if some future mining project impacts the groundwater, we can now use this pore water isotope records as a novel baseline to help determine the extent of the impact.
Recent research published in Scientific Reports has shown how cave formations preserve a history of past climate.
Groundwater levels and aquifer storage
There are two common mistakes often made when calculating how much groundwater storage levels have changed.
Quantifying vertical water flow using natural heat as tracer
Ancient water to drain from farmland without ongoing joint management
The management of withdrawals of ground water in the Central West remains an area of hotly-contested debate. Associate Professor of Hydrogeology Bryce Kelly has spent over a decade studying groundwater in the Central West, and has credited groundwater with “saving rural communities from collapse”, but its potential for future drought-proofing depends on how successfully it’s managed. He says current withdrawals “will only be sustainable if the Narromine region gets flooded frequently enough to balance the volume of groundwater extracted."
