Hallway Conversations – Jaime Gómez-Hernández

A –Streams of Thought– contribution by Kevin Roche.

In our inaugural Hallway Conversations article we have the pleasure of learning about the most recent AGU Chapman Conference through the eyes of its principal organizer, Jaime Gómez-Hernández (JGH), a professor of hydrogeology from the Universidad Poletécnica de Valencia. Together with the Chapman planning committee, Professor Gómez-Hernández brought researchers from around the world together for a week of presentations, discussions and activities in his native Valencia, Spain. “The MADE Challenge for Groundwater Transport in Highly Heterogeneous Aquifers” highlighted current understanding and future needs to address the growing threat of aquifer contamination. Discussions centered on the Macrodispersion Experiment (MADE) Site, located on the Columbus Air Force Base in Mississippi, USA. Thirty years of experiments and site characterization have made it one of the most intensively-studied aquifers in the world; and although its sampling wells are no longer in place, MADE’s rich datasets are still used to test novel groundwater modeling theory.

Introducing Hallway Conversations

Contribution by Kevin Roche.

Hydrology is a broad field for good reason. I began this article after telescoping through a series of cited articles for two hours, moving from a review of bacterial biofilms to a paper on complex networks. We rely on scores of different specialties to connect our measurements to theory. Yet, if we ever hope to establish our academic autonomy, young hydrologists are tasked with digging in. For me, this “broadening-specialization dualism” is frustrating, perhaps because it forces me to admit (1) hydrology is far from being solved, and (2) I need an immense amount of help connecting my work to the big picture.

Moving beyond a snapshot: towards a time-continuous understanding of hyporheic exchange

A –Streams of Thought– contribution by Adam N. Wlostowski. PDF Version

Hi All! Recently, I received a 2015 AGU Horton Research Grant. I am very grateful and honored to accept this grant. I’d like to use this post to share my proposed research questions and methods with the YHS community.

What is a Hyporheic Zone and Why Should We Care?

Flowing stream waters are hydrologically connected to adjacent groundwaters. These connections help maintain the physical and chemical integrity of streams. In a uni-directional sense, streams lose and gain water to/from groundwater aquifers. In a bi-directional sense, streams are connected to groundwaters via hyporheic exchange (HE) flowpaths. HE moves water, nutrients, dissolved oxygen, and carbon into and out of hyporheic zones (HZs) – saturated subsurface regions beneath and adjacent to a stream channel, where streamwaters and groundwaters mix. In the HZ, sufficiently long residence times and contact with microbes facilitates nutrient transformations vital to the health of stream ecosystems (Boulton et al., 1998). Continue reading

Remote Sensing in the Geosciences, a session at the 2015 AGU Early Career Scientist Conference

The 2015 AGU Early Career Scientist Conference will feature a 1-hour session on Remote Sensing in the Geosciences. The goal of session is to provide early career scientists with an overview of a few cutting-edge remotely sensed data products, and their applications in hydrology.

This session will feature three speakers: George Roth, an engineer at the Polar Geospatial Center at the University of Minnesota, will discuss the power of very high-resolution commercial satellite imagery. Chris Crosby, a project manager at UNAVCO in Boulder Coloroado, will share recent advancements in Terrestrial Laser Scanning (TLS) and how OpenTopography can help early career scientists access high-resolution topographic data for FREE! Joe Levy, at the University of Texas at Austin, will cap the session off with a captivating research presentation showing how TLS and high-resolution commercial satellite imagery help us understand basic hydrologic process in the McMurdo Dry Valleys of Antarctica, an fantastic Earthly analog to Mars.
