We’re a group of water resources engineers and scientists led by Desirée Tullos in the Biological and Ecological Engineering department at Oregon State University. Through field and modeling studies, we study questions around the physical and biological processes in rivers, from the particle to basin scale, that inform the sustainable management of rivers.

Current and past research includes:

  • Responses to river restoration and engineering, including dam removal, engineered log jams, and dam reoperation
  • Impacts of dam operations on flood risk reduction, water supply, hydropower generation, and environmental requirements
  • Analysis of uncertainty in water resources modeling
  • Effects of hydropower development in China
  • Mechanics of flow around dense vegetation
  • Sediment management in reservoirs
  • Fish use of turbulance around engineered log jams
