Researching the connections between ecohydrological processes and human interactions in an ever-changing climate.

  • We investigate land use effects on ecological and hydrological processes and interactions.

  • We study surface water and groundwater relationships in watersheds and riparian areas. 

  • We use a systems approach to enhance base knowledge regarding watershed-riparian function.

  • We collaborate with multiple stakeholders including producers, state and federal agency personnel, and researchers from various institutions.




Dr. Carlos Ochoa is a faculty member (and can take graduate students) in:

Department of Animal and Rangeland Sciences (Rangeland Sciences)

Water Resources Graduate Program (Water Resources Science)

Environmental Sciences Graduate Program (Environmental Sciences)

Master of Natural Resources - online 





Dr. Ochoa was a plenary session speaker invited to present on his ongoing research and technology used to investigate surface water and groundwater relationships on rangeland and agricultural systems of Oregon and other parts of the West. The event organized by the Mexican Society for Rangeland Management, University of Chihuahua, and the Agriculture Reseach Institute INIFAP was held on October 17-18, 2019 in Chihuahua, Mexico.
Dr. Carlos Ochoa from OSU was the invited speaker to deliver a lecture on integrated watershed-riparian systems management to faculty and students of the Universidad Autonoma de Chihuahua (UACH) in Mexico. Dr. Ochoa discussed his research findings regarding surface water and groundwater relationships occurring on rangeland ecosystems of central Oregon. The event took place on 21 March 2019 at UACH’s Facultad de Zootecnia y Ecologia (Department of Animal Science and Ecology) auditorium in Chihuahua City, Mexico.
During the last two weeks of November 2018, Nicole Durfee, a Ph.D. student in our Ecohydrology team, will be leading a series of presentations based on her doctoral work on Unmanned Aerial Vehicles (UAVs) at OSU. During her various presentations, she will speak to various groups in the Falkland Islands, in South America, on the use of UAVs on agricultural, rangeland, and forestry applications. Several workshops will be held over this time to provide participants with “hands-on” experience with UAV operation, mapping, and basic image processing. Nicole's participation in this event is possible through a partnership with the South Atlantic Environmental Research Institute’s Coastal Habitat Mapping project, through the Shackleton Scholarship Fund.
Riparian physical function and grazing management techniques were some of the topics discussed during a Riparian Grazing Management Workshop supported by the National Riparian Service Team (NRST) and organized by the Klamath Watershed Partnership in Oregon. Dr. Carlos Ochoa participated as one of the instructors along with Sandy Wyman, MIke Borman, and David Bradford from the NRST.
