At Oregon State we teach and do research on
physical and chemical processes in groundwater and groundwater
interactions with geologic processes. We have an active research
group that works on pore-scale processes such as two-phase flow and
diffusion, groundwater-surface water interactions, and modeling of
groundwater flow and solute transport. The hydrogeology group
collaborates in teaching and research with hydrologists in Civil,
Bioresources and Forest Engineering and Soil Science. Most
alumni from the group work in environmental consulting and government
agencies.
Dorthe Wildenschild, our newest professor
in hydrogeology, and her students are interested in the
hydrologic,
thermal,
and
geophysical characterization
of porous media, in pore-cale
processes and modelling, contaminated groundwater characterization and remediation
- for instance, using electro-osmosis. Her newest project
involves the use of X-ray micro-tomography and pore-scale modeling to
evaluate pore-scale processes in porous media in the presence of two
phase flow.
Roy Haggerty and his students currently
work on exchange of water between streams and the shallow subsurface
(the hyporheic zone), on nitrate transport through sediments below
agricultural lands in Oregon, groundwater flow modeling, and on the
physics of solute transport in highly heterogeneous materials.
Students have worked on the role of groundwater in geologic processes,
nuclear waste disposal, and stream turbidity. Recent funding for
research has come from the Dept. of Energy, National Science
Foundation, Sandia National Laboratories, and state agencies in
Oregon.
