Written by Scott Jasechko University of Calgary isohydro.ca twitter.com/sjasechko Groundwater is renewed by rain and melted snow that moves under the ground, a process called groundwater recharge. The percentages of summer versus winter precipitation that make it under the ground are expected to be different for a number of reasons including larger plant water use during the summer, and larger are ...[Read More]
Written by Brian Smerdon IAH regional groundwater flow commission In the early 1960’s József Tóth published seminal work on the concept of regional scale flow and nested flow systems. His work built on the “theory of groundwater motion” by M.K. Hubbard, and seemed to come along just at the right moment in history of hydrogeology. Armed with József Tóth’s work, the hydrogeologic community (geologis ...[Read More]
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]
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]
One of the first things I realized when designing this blog was that groundwater is not photogenic, in the extreme. Seriously: I dare every hydrogeologist to go to google images and search ‘groundwater‘. You find something like this: I am not saying that I dislike conceptual models or think they are ugly. I actually quite like them, which maybe explains my current profession! But I ...[Read More]
We all know about the flaws of impact factors, including how they lead to citing recent research, self-citing etc. But I thought it would be handy to compile a list of journals where well-cited groundwater articles are most often published. Like it or not, I sometimes look up this information and I assume other people do to. The impact factor is certainly not the only factor I use to decide where ...[Read More]
Mark Ranjram, a Masters student in my research group, wrote a paper on crystalline permeability that is coming out in a special edition of Geofluids on ‘Crustal Permeability’ early in 2015 (other cool papers in early view here). Here is Mark’s awesome response when I asked him if he wanted to write a plain language summary:
Food prices in the United States are increasing slightly but not as significantly as one might expect given the severe drought in California. Margret Munro, a science journalist with Postmedia, recently asked me a great question: is groundwater depletion keeping California fruit and veggies cheap during the severe drought? Following up on her article, here is what I found and what it means for the ...[Read More]
Press release from McGill University of our research published yesterday in Nature Geoscience. Water scarcity is not a problem just for the developing world. In California, legislators are currently proposing a $7.5 billion emergency water plan to their voters; and U.S. federal officials last year warned residents of Arizona and Nevada that they could face cuts in Colorado River water deliveries i ...[Read More]
