I went from a BSc (Hons) student, who was not considering continuing my postgraduate studies at all, to someone who is passionate about water resource research and continuing my postgraduate career. This is apparently common amongst postgraduate students in science…

Post by Samuel Zipper, postdoctoral fellow at both McGill University and the University of Victoria, in Canada. You can follow Sam on Twitter at @ZipperSam. ___________________________________________________________ Dedicated Water Underground readers know that this blog is not just about water science, but also some of the more cultural impacts of groundwater. Keeping in that tradition, today’s post begins with a joke*: Knock, knock! Who’s there? Your neighbor Your neighbor who? Your neighbor’s groundwater, …

What is the difference between ‘water withdrawal’ and ‘water consumption’, and why do we need to know?
Last week I had to teach my first class in global hydrology. When I showed the global trend on increasing demands and withdrawals I needed to explain the different terms as sometimes the term “water use” gets, well, misused.

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 the highways as the salt has the desired effect of melting the ice, or carried away by rain. This salty ‘runoff’ ends up in streams nearby via pipes which drain the highway.

Post by Andy Baker, University of New South Wales The effects of fire on the surface environment are clear to see. Landscapes are coated in ash. Intense fires can destroy all vegetation and alter soil properties. Less intense fires destroy just the surface leaf litter, grasses and shrubs. Grass fires can be fast moving, destroying buildings and threatening lives. Intense fires can even form their own local weather systems. But …

Welcome to the first edition of groundwater speed dating. In today’s post I introduce you to a motley crew of isotopes and chemicals that hydrogeologists and geochemists use to date the age of groundwater.

Seventy-five percent of EU inhabitants depend on groundwater for their water supply, which makes groundwater management extremely important. To manage groundwater effectively during drought periods like 2015, data about groundwater levels are needed in (near-) real time.

Post by Scott Jasechko, University of Calgary Groundwater is the world’s largest family of fresh and unfrozen water, and its members range from young to old. There are toddler groundwaters recharged more recently than the year ~1960. Our earlier research showed that these modern groundwaters make up only a small share of global groundwater stocks (Ref. 1 and Water Canada). But what of ancient ‘fossil’ groundwater—defined as groundwater that first …

Writing my first contribution to the Water Underground blog I want to take advantage of this less formal environment. I will introduce karst as I and many others around the world see it. As the most beautiful environment to explore and study.
