Crop kites
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 …

Socio-hydrogeology: bridging the gap between science and society
Authored by Viviana Re, Marie Curie Research Fellow at Ca’ Foscari University of Venice, Italy Sustainability, integrated water resources management, climate change, groundwater governance. These are some of the currently trending topics in hydrogeology, as reflected by their widespread use as keywords in recently published literature. Indeed, hydrogeologists are at the forefront of guaranteeing the long-term sustainability of aquifers worldwide. But how can they assure that the outcomes of their investigations are …

Brackish groundwater resources: is development advisable?
Authored by: Grant Ferguson – Assistant Professor in the Department of Civil & Geological Engineering at the University Saskatchewan Groundwater makes up a large fraction of the Earth’s freshwater but that represents only a part of groundwater resources. Large volumes of groundwater are saline, with some reaching salinities of over ten times that of seawater. Brackish water is an intriguing part of the spectrum of groundwater resources, sitting just beyond the water quality salinity requirements …

The great American groundwater road trip: Interstate 80 over the Ogallala Aquifer
Authored by: Sam Zipper – Postdoctoral Researcher in the Department of Civil & Environmental Engineering at the University of Wisconsin-Madison In late July, my wife and I loaded the dog into the car, cranked up the water-related tunes, and drove over a few million cubic meters of water. No, we haven’t traded in our sedan for an amphibious vehicle – rather, we were driving west, across Nebraska, on the …

FloPy: A Python interface for MODFLOW that kicks tail!
Authored by: Kevin Befus – Assistant professor, Department of Civil and Architectural Engineering at the University of Wyoming Groundwater modeling is getting better. Models are becoming more sophisticated with simpler interfaces to add, extract, and process the data. So, at first appearances, the U.S. Geological Survey’s (USGS) recent release of a Python module named FloPy for preparing, running, and managing MODFLOW groundwater models seems to be a step backwards. Oh, but it …

Nature Geoscience digging into water underground this month!
Nature Geoscience is digging hard into water underground – the February issue is part of a special focus on groundwater. The cover this month is a gorgeous (groundwater-filled?) waterfall by Glen Jasechko, Scott’s brother. The groundwater focus includes: commentary on drought in the Anthropocene, led by Anne van Loon news and views pieces by Ying Fan and Tamara Goldin our paper on the volume and distribution of modern groundwater a …

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 group. The listserve is used primarily to exchange scientific and technical …

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 thermonuclear testing. But tritium has a short half-life, so …
