There has been a decline in rainfall recharge to groundwater over the last ~20 years due to reduced rainfall which is unprecedented for the last 800 years!

Despite how simple it sounds, there's still a lot we don't know about the water cycle. Especially when it comes to groundwater. 💧
That's why we're part of a team of researchers from @UNSW, @Flinders, and @Deakin exploring a new approach to groundwater. https://t.co/YLyE9dTJCL
A new way to understand groundwater replenishment by monitoring the water moving from the surface to the water table by using underground spaces - tunnels, mines, caves, etc. - as 'observatories of groundwater recharge' is presented at https://t.co/846QcKilFT
Comments welcome!!
We've been exploring caves to unlock the secrets of groundwater.
In a world-first study, we've used caves to show the decades-long decline in rainfall in south-west Australia has reduced the replenishment of groundwater in the region to an 800-year low. https://t.co/8Ioddsticb
South-west Australia relies on groundwater for three-quarters of its water use.
But a new study of the region’s caves by @StacePriestley + colleagues has found a drying climate is having a dramatic impact on this precious resource.

The current level of rainfall recharging #groundwater in southwest WA is at its lowest for at least the last 800 years. A pioneering technique developed at ANSTO, experts in water resource analysis, was crucial in this research.

1/5 Southwest WA is experiencing its lowest level of groundwater recharge from rainfall in at least 800 years, according to @CSIRO, @ANSTO & @UNSW research:

How have rainfall and groundwater recharge rates changed in southwestern Australia over the past 800 years?
Stacey Priestley @StacePriestley explains why speleothem records can be used to reconstruct these changes

Fantastic to see this critical research published as part of our #ProjectCoorong trials and investigations program. Great work @envir_scientist + team!
We also have exciting news coming soon regarding further work in the Coorong, Lower Lakes and Murray Mouth region...stay tuned!
Long term water quality datasets are extremely valuable. In this work lead by @envir_scientist we look at trends in water quality over a >20 year period to see the effects of reduced flushing on eutrophication on the Coorong https://t.co/xWOFiQYUOg
The Coorong is a special and unique estuary at the end of Australia's largest river system, in our new study we document how reduced flushing has led to a long term decline in its water quality and sediment health @UofA_SET@goyderinstitute @SAEnvirWater https://t.co/dlXuTBg1zX
