Hydrogeology and Water Resources ("Hydro") Group
Our Hydro research group uses modeling-, field-, and laboratory-based approaches to understand:
→ Groundwater and suface water resource availability, sustainability, and vulnerability assessment;
→ Vadose zone (unsaturated zone) and soil-water processes, including quantifying & mapping recharge quantity and quality and preferential flow;
→ Low Impact Development (LID) effects on recharge quantity and quality
→ Hydroclimatology and climate change / variability effects on water resources;
→ Contaminant hydrogeology and nonpoint-source contamination at watershed to regional scales, including groundwater-vulnerability assessments to nitrate;
→ Saltwater intrusion and submarine groundwater discharge as related to the management of coastal aquifers systems;
→ Interdependencies between climatic-hydrologic-land use and subsurface processes;
→ Geographic Information Systems (GIS) modeling and uncertainty analysis.
Interested In Joining Our Group?
Our Hydro group is growing. We are looking for new students interested in
research that compliments and expands our current research in hydrogeology,
vadose zone hydrology, contaminant hydrology, and climate change effects on
water resources. Please contact Jason Gurdak for more information or see the Department of Earth & Climate Sciences website or the Graduate Studies web site for program
details and admissions requirements.

4. Human-Environmental Security in Asia-Pacific Ring of Fire: Water-Energy-Food Nexus, Taniguchi, M. (PI, Research Institute for Humanity and Nature, Kyoto, Japan) (Gurdak is Leading the U.S. research group, which 1 of 7 across the Asia-Pacific region), Japanese Ministry of Education, Research Institute for Humanity and Nature (RIHN), Kyoto, Japan. project period: 2013-2018. Link to project website.
5. Paleohydrological Change and Fluvial Archives, Paleogroundwater Group, INQUA Commission on Terrestrial Processes, Deposits, and History (TERPRO), 2012-2015, International Focus Group: G@GPS Groundwater and Global Palaeoclimate Signals. See TERPRO page for overview of G@GPS.
6. In 2011, the new G@GPS initiative (Groundwater@Global Paleoclimate Signals) was launched to help the international paleogroundwater research community in coordinating activities that advance investigations of the links between paleoclimate archives and paleogroundwater observations. G@GPS is an inclusive group of scientists that coordinates paleogroundwater research, organizes workshops and training courses, and helps future and early-career researchers develop necessary skills. If you are interested in participating in G@GPS, please contact me or one of the other coordinators (see the invitation letter here: PDF). Learn more about G@GPS here.
7. Groundwater Resources Assessment under the Pressures of Humanity and Climate Change (GRAPHIC) (2005 - present). Gurdak is Co-Coordinator GRAPHIC along with Marc la Blanc. Visit the GRAPHIC website here.
