WaterUnderground

Groundwater—the world’s largest freshwater store— is a life-sustaining resource that supplies water to billions of people, plays a central part in irrigated agriculture and influences the health of many ecosystems. Water Underground is a groundwater nerd blog written by a global collective of hydrogeologic researchers for water resource professionals, academics and anyone interested in groundwater, research, teaching and supervision. The blog, started by Tom Gleeson and managed by Xander Huggins, is the first blog hosted on both the EGU blogs and the AGU blogosphere.

Celestial groundwater – the subsurface plumbing for extraterrestrial life support

Celestial groundwater – the subsurface plumbing for extraterrestrial life support

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

Of Karst! – short episodes about karst

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]

Water: underground source for billions could take more than a century to respond fully to climate change

Water: underground source for billions could take more than a century to respond fully to climate change

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

Groundwater and drought

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]

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]

How deep does groundwater go? Mining (dark) data from the depths

How deep does groundwater go? Mining (dark) data from the depths

Post by Kevin Befus, Assistant Professor at the College of Engineering and Applied Science at the University of Wyoming, in the United States. __________________________________________________ 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 va ...[Read More]

Data drought or data flood?

Data drought or data flood?

Post by Anne Van Loon, Lecturer in Physical Geography (Water sciences) at the University of Birmingham, in the United Kingdom. __________________________________________________ The basis for (almost) all scientific work, at least in the earth and environmental sciences, is DATA. We all need data to search for the answers to our questions. There are a number of options to get hold of data; we can ...[Read More]
