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.

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.

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.

With the climate strikes happening all over the world, I sometimes wish I had a crystal ball that would allow me to look into the future. Or even better, a crystal ball that could show me different scenarios of what will happen if we change, or not. Well, I do not have a crystal ball, but I do have a global scale hydrological model.

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.

When the Cape Town water crisis first emerged it took almost a year before active contingencies were put in place. Four major ideas were proposed: (1) Intense water restrictions for municipal water users, (2) greywater recycling facilities, (3) groundwater augmentation of water supplies, and (4) desalination.Although not all the proposed ideas came to fruition, there was a significant increase in the installation of well points and boreholes for municipal and private use.

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.

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.

‘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’?

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.

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.

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.

Education and capacity development can become more integrated in our work, in academia, if we emphasize and increase our attention given to finding the most effective way to train and motivate the new generations of hydrogeologists

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.

Post by Matt Herod, Waste and Decommissioning Project Officer for the Canadian Nuclear Safety Commission, and Adjunct Professor in Earth and Environmental Science at the University of Ottawa, in Ottawa, Canada. _______________________________________________ I have always been a mineral and fossil collector. It was a hobby that stuck and blossomed into a career. I still collect minerals and fossils, although I’ve now added rocks from my field sites to the collection. One …

I want to share a book with you that has encouraged me through initial academic mires (I was only in graduate school for 7 years…) and inspired me to expand my perception and appreciation of the natural world.

In recent years the human dimension of hydrology has become increasingly important.

Episode 2: Dissolving rock? (or, how karst evolves). This episode will now deal with the processes that create such amazing surface and subsurface landforms. The widely used term “karstification” refers to the chemical weathering of easily soluble rock composed of carbonate rock or gypsum.
