Groundwater pumping poses worldwide threat to riverine ecosystems
When will critical river flows be reached where you live?

Post by Inge de Graaf, Assistant Professor of Hydrological Environmental Systems at the University of Freiburg. 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, bu ...[Read More]

A do-it-yourself Jupyter notebook to constrain sediment permeability

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 eas ...[Read More]

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]

Community advice to young hydrologists, Part 1

We at Water Underground loved reading Young Hydrologic Society’s post titled “Community advice to young hydrologists” – an advice column written by a network of established scientists in the field. We appreciated the column so much, in fact, that we have decided to re-blog the post to you (with YHS’s consent, of course). We’ve split up their post by question, and have added in hyperlinks to all co ...[Read More]

Post by Andreas Hartmann,  Assistant Professor in Hydrological Modeling and Water Resources at the University of Freiburg. __________________________________________________ Episode 3 – Learning about karst by … KARST IN THE MOVIES! Before writing about karst hydrology in “Of Karst! Episode 4”, I have been urged to present some more visual information on karst landforms. Of Karst! Episode 1 focuse ...[Read More]

Where does the water in streams come from when it rains?

Post by Anne Jefferson, associate professor in the Department of Geology at Kent State University, in the United States. __________________________________________________ The title of this blog post might seem like a question with an obvious answer, or even a silly question to pose on a blog devoted to groundwater, but if you don’t see the connection between streamflow and underground water, you ...[Read More]

Keeping in that tradition, today’s ...[Read More]

Is highway de-icing ‘a-salting’ our aquifers?

Is highway de-icing ‘a-salting’ our aquifers?

Post by Mark Cuthbert, Cardiff University, and Michael Rivett, GroundH20 plus Ltd; University of Strathclyde. If you live in a cold climate, have you ever wondered where all the de-icing salt (or ‘grit’ as we call it in the UK) that gets spread on the roads in winter time ends up, aside from that accumulating salty grime that coats your car? As you might expect, most of the salt gets washed off th ...[Read More]

The Groundwater Wetlands and Bogs Study Group

The Groundwater Wetlands and Blogs Study Group is an unfunded, voluntary collaboration of professionals, formed in December 2012, focused on groundwater wetlands, bogs, and related systems.  The Study Group has about 250 members in 39 countries. Study Group members communicate primarily through a disciplined Yahoo Group listserve.  We are not a social network nor are we an environmental advocacy g ...[Read More]

Are we in the age of postmodern groundwater?

Are we in the age of postmodern groundwater?

My humanities colleagues and friends are always talking about postmodernism or pomo for short (see this funny satire). I’ve been thinking a lot lately about ‘modern groundwater’ (stay tuned for a cool paper), so I started wondering if there is ‘postmodern groundwater’. Modern groundwater is groundwater recharged since the huge spike it tritium in the early 1960’s due to above ground th ...[Read More]
