Groundwater and climate change revisited: informing adaptation in a warming world
Recent research has identified the natural resilience of groundwater to climate change and our tendency to deplete this invaluable resource. It’s time we understood, valued, and governed groundwater as the vital adaptation to climate change that it is.

Re-thinking watersheds from the bottom up
Despite a few decades of progress on groundwater-surface water interaction and the advent of integrated groundwater-surface water models, it was clear that very different conceptual models of how groundwater fits into the hydrologic cycle were held by different communities within hydrology.

Global Groundwater Sustainability – A Call to Action… do you want to sign?
I am excited about a new initiative called “Global Groundwater Sustainability: A call to action” that was first drafted at the recent Chapman conference in Valencia, Spain. Overall, we are a global group of scientists calling for action to ensure groundwater benefits society now and into the future, and hope that you would like to join us by signing.

Upcoming Chapman conference “Quest for Sustainability of Heavily Stressed Aquifers at Regional to Global Scales”
Abstracts are due soon (July 10th) for the upcoming Chapman conference on groundwater sustainability on Oct 21-24, 2019 in Valencia Spain.

Data sharing: an update on new and existing initiatives
Last year, Anne Van Loon wrote about data sharing initiatives in hydrology (“Data drought or data flood?” 28 May 2018). This post gives an update on existing and new initiatives.

Video: Linking water planetary boundaries and UN Sustainable Development Goals
Water Underground creator Tom Gleeson prepared this quick research video (with no more than a toothbrush, a file holder, and a doughnut, in one take!) for the Ripples project meeting at the Stockholm Resilience Centre, that was held in April. In this video, he talks about using doughnut economics for linking water planetary boundaries and UN Sustainable Development Goals.

Have you ever wondered if groundwater is connected to climate?
‘Groundwater-surface water interactions’ has become standard hydrologic lexicon and a perennial favorite session title at various conferences… but how often do you hear the phrase ‘groundwater-climate interactions’?

Celestial groundwater – the subsurface plumbing for extraterrestrial life support
Have you ever taken a walk on the beach during a lowering (ebbing) tide and see mini-rivers grow and create beautiful drainage patterns before your eyes? These short-lived groundwater seepage features are tiny (and fast) analogs of how groundwater has shaped some parts of Mars! It appears that groundwater loosening sediments can lead to all sorts of scales of erosion on both Earth and Mars.

Of Karst! – short episodes about karst
We often associate groundwater with large water storage and very slow water movement, for instance compared to rivers. But is it possible that groundwater flow can be as quick as stream flow? Of karst, it is possible!

Water: underground source for billions could take more than a century to respond fully to climate change
While climate change makes dramatic changes to weather and ecosystems on the surface, the impact on the world’s groundwater is likely to be delayed, representing a challenge for future generations.

the true meaning of life for a hydrogeologist….
I stumbled upon this quote from Nelson Henderson (a farmer from Manitoba) which encapsulates what I have been thinking about groundwater sustainability for a number of years…

Unconventional Oil and Gas Development and Groundwater – Comparing the English and Canadian Experiences
The differences between the English and Canadian experiences of unconventional hydrocarbon development were apparent at a meeting co-hosted by the British Geological Survey, Geological Society of London and IAH in London in July 2018.

How deep does groundwater go? Mining (dark) data from the depths
We’ve all been asked (or do the asking), “where does your water come from?” This is a fundamental question for establishing a series of additional questions that can ultimately help define strategies for valuing and protecting a particular water resource.

Happy birthday plate tectonics!
As we’ve firmly moved into 2018, we can say happy 50th birthday to one of the most revolutionary scientific theories of the last century: plate tectonics. Here we discuss the birth of plate tectonics and what it means for hydrogeology.

From groundwater flow to groundwater glow: why does groundwater fluoresce in ultraviolet light?
…if we shine ultraviolet light at groundwater samples, then they fluoresce due to the presence of organic molecules that are often present. Unfortunately, we can’t see any of this fluorescence with our eyes, as it is emitted in the middle- and long-range ultraviolet, so we must use detectors that can ‘see’ at these wavelengths.

Where does the water in streams come from when it rains?
If you don’t see the connection between streamflow and underground water, you need to keep reading.

Western water wells are going dry
We recently mapped groundwater wells across the 17 western states [1], where half of US groundwater pumping takes place.

Good groundwater management makes for good neighbors
Post by Samuel Zipper, postdoctoral fellow at both McGill University and the University of Victoria, in Canada. You can follow Sam on Twitter at @ZipperSam. ___________________________________________________________ Dedicated Water Underground readers know that this blog is not just about water science, but also some of the more cultural impacts of groundwater. Keeping in that tradition, today’s post begins with a joke*: Knock, knock! Who’s there? Your neighbor Your neighbor who? Your neighbor’s groundwater, …
