Update on the groundwater situation in Cape Town

WaterUnderground 3rd June 2019

Freeze-frame from the featured IAEA video on drought conditions in Cape Town.

Post by Jared van Rooyen, PhD student in Earth Science at Stellenbosch University, in South Africa. 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) des ...[Read More]

Word cloud of blog post “Data drought or data flood?” 28 May 2018

Post by Anne Van Loon, Gemma Coxon, and Bentje Brauns. 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. CAMELS (Catchment Attributes and MEteorology for Large-sample Studies) The CAMELS datasets are expanding: from the United States and Chile to Great Britain and Austr ...[Read More]

Video: Linking water planetary boundaries and UN Sustainable Development Goals

WaterUnderground 7th May 2019

Tom Gleeson talking about doughnut economics and showing great doughnut eating restraint.

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. Display "Linking wat ...[Read More]

Dowsing for interesting water science – what’s exciting at EGU 2019?

WaterUnderground 5th April 2019

Is that a crowd of geoscientists wandering through Vienna?

Joint post by Sam Zipper (an EGU first-timer) and Anne Van Loon (an EGU veteran). 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! To help narrow down the schedule! ...[Read More]

Have you ever wondered if groundwater is connected to climate?

WaterUnderground 1st April 2019

Post by Tom Gleeson, Assistant Professor in Civil Engineering at the University of Victoria. ‘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’? A group of hydrologists, hydrogeologists, atmospheric scientists and geodesists that met i ...[Read More]

Celestial groundwater – the subsurface plumbing for extraterrestrial life support

WaterUnderground 25th March 2019

Post by Kevin Befus, Assistant Professor in Civil and Architectural Engineering at the University of Wyoming. 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 (Fig. 1A) are tiny (and fast) analogs of how groundwater has shaped some parts of Mars! ...[Read More]

Of Karst! – short episodes about karst

WaterUnderground 15th March 2019

Post by Andreas Hartmann, Assistant Professor in Hydrological Modeling and Water Resources at the University of Freiburg. Episode 4 – Karst Groundwater: quick and slow at the same time? 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 and, at the same aquife ...[Read More]

WaterUnderground post by Mark O. Cuthbert, Cardiff University; Kevin M. Befus, University of Wyoming, and Tom Gleeson, University of Victoria Groundwater is the biggest store of accessible freshwater in the world, providing billions of people with water for drinking and crop irrigation. That’s all despite the fact that most will never see groundwater at its source – it’s stored naturally below gro ...[Read More]

Groundwater and drought

WaterUnderground 8th October 2018

Wellington, NSW, April 2018. There has been no rainfall recharge of the groundwater here for 16 months (and counting). How do we know?

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 ...[Read More]

Groundwater and Education – Part two

WaterUnderground 2nd August 2018

Post by Viviana Re, postdoctoral researcher at the University of Pavia (Università di Pavia), in Italy. You can follow Viviana on Twitter at @biralnas. Part two of a two-part series on groundwater and education by Viviana. __________________________________________________ In my last post (“Drawing out groundwater (from the well)”) I wrote about the reasons why, as groundwater scientists, we shoul ...[Read More]
