Dr. C. Rhett Jackson

Interim Dean of Academic Affairs
John Porter Stevens Distinguished Professor of Water Resources
IRIS faculty, River Basin Center Faculty

I conduct trans-disciplinary investigations of water quality issues in collaboration with faculty from Crop and Soil Sciences, Ecology, Engineering, Entomology, Geography, Geology, Marine Sciences, and other programs. Investigators of water resource issues at the University of Georgia are broadly distributed across schools and disciplines. I am a member of IRIS - Institute for Resilient Infrastructure Studies and the RBC - Riber Basin Center. For more information on water programs at UGA, see the link below.

Research Areas:
Research Interests:

My research interests include the effects of human land use activities, specifically forestry, agriculture, and urbanization, on water quality and aquatic habitat and the effectiveness of best management practices (BMPs) in reducing such nonpoint source pollution.  A particular current interest of mine is the relationship between riparian vegetation and channel structure and stream temperature. My work is trans-disciplinary, and I frequently collaborate with ecologists, animal biologists, and biogeochemists. Most of my applied research is viewed through the lens of hillslope hydrologic processes, my basic research interest.
