Post by Elco Luijendijk, Junior lecturer in the Department of Structural Geology and Geodynamics at Georg-August-Universität Göttingen and WaterUnderground founder Tom Gleeson (@water_undergrnd), Associate Professor in the Department of Civil Engineering at the University of Victoria. Most of the groundwater on our planet is located in sedimentary rocks. This is why it is important to know how easy or hard it is for water to flow through pores in sediments, …

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.

Every April, the European Geophysical Union (EGU) holds an annual meeting in Vienna. With thousands of presentations spread out over a full week, it can feel like you’re surrounded by a deluge of water-related options – particularly since the conference center is on an island!

‘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.

Post by Andy Baker, Professor researching groundwater, caves, past climate, organic carbon and more at the University of New South Wales, in Australia. __________________________________________________ Drought is in the news here in New South Wales, Australia. But how are rainfall, drought and groundwater related? First, we need to understand what drought is. Is it a water shortage? Or a lack of rainfall? Or something else? In the USA, the National Climatic Data Center …
