We’re only a few sols from southern winter solstice in Gale Crater on Mars, which means it’s pretty much the coldest time of year and the best time for Curiosity to try to see water frost on the surface.

I want to share a book with you that has encouraged me through initial academic mires (I was only in graduate school for 7 years…) and inspired me to expand my perception and appreciation of the natural world.

If you don’t see the connection between streamflow and underground water, you need to keep reading.

Could groundwater be a previously unrecognised source or sink of carbon?

In recent years the human dimension of hydrology has become increasingly important.

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…

Globally, the need for regional hydrologic humanitarian efforts is obvious. Even today, 1,000 children die due to diarrhoeal diseases on a daily basis.

Episode 2: Dissolving rock? (or, how karst evolves). This episode will now deal with the processes that create such amazing surface and subsurface landforms. The widely used term “karstification” refers to the chemical weathering of easily soluble rock composed of carbonate rock or gypsum.

Post by Matthew Robert Bennett, Bournemouth University and Mark O Cuthbert, Cardiff University Our ancient ancestors seem to have survived some pretty harsh arid spells in East Africa’s Rift Valley over five million years. Quite how they kept going has long been a mystery, given the lack of water to drink. Now, new research shows that they may have been able to survive on a small networks of springs. The …

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.

Post by Kevin Befus, University of Wyoming I don’t mean to get your hopes up, but keep them up there. I’m not talking about recording the sonorific excitement that is groundwater flow. And, I’m not talking about the squeak of a pump handle, the gurgling of a spring, the grumble of a generator, or the roar of a drill rig. Rather, I want to share with you some songs that …

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.

An insect infestation killing hemlock trees in New England is having a significant impact on essential water supplies in one of the nation’s most populous regions, a new study finds. The study is the first to show an increase in water yield, the amount of water reaching streams and rivers, resulting from forest damage caused by an insect pest called the hemlock woolly adelgid.

Fourth year and graduate students led a fun mini-conference during class in Groundwater Hydrology (CIVE 445, Civil Engineering at University of Victoria) yesterday. Local consulting and government hydrogeologists joined, making the students both nervous and excited to be presenting to professionals with up to forty years of groundwater experience.

Everyone (in California, at least) has seen those clips that get run every winter of the snow surveys: people walking out into a white-blanketed meadow to shove a pole into the snow and record the depth. Or, in the case of the 2015 broadcast, walking out onto muddy grass and gesturing sadly at a lack of snow in which to do this. It’s a good photo op, but the broadcasts rarely follow up with much of the science behind the survey.

Post by WaterUnderground contributor Mikhail Smilovic. Mikhail is a PhD candidate in the Department of Civil Engineering at McGill University, in Quebec. Crops use water for photosynthesis, absorbing nutrients, and transpiration, or the plant-equivalent of sweating. A crop may experience water-stress if the soil surrounding the roots is not adequately wet, and this stress will affect the crop differently depending on the crop’s stage of growth. Irrigation is the watering of …

Researchers have discovered a large concentration of sediment deposits at the end of Monterey Canyon, an underwater chasm beneath Monterey Bay, California. The sediment deposits are relatively young and may be more likely to catalyze underwater landslides than other sections of the canyon, according to the researchers who presented their discovery at the 2016 American Geophysical Union Fall Meeting.

Permafrost loss due to a warming Alaska is leading to changes in the chemistry of the Yukon River Basin with potential global climate implications. This is the first time a Yukon River study has been able to use long-term continuous water chemistry data to document hydrological changes over such an enormous geographic area and long time span.
Wildfires can perpetuate mercury contamination by releasing it from soil and plants and spreading it through smoke and ash. It doesn’t take much heat to convert mercury to a gas.
