Dr. Gabet's Website



  • Ph.D. 2002, University of California- Santa Barbara

Research Interests

  • Professional interests are in sediment transport processes and landscape evolution. Projects include investigating landslides and debris flows in the Himalayas and California; examining the role of fire and vegetation in modulating erosion rates; derived sediment transport equations for different bioturbation processes; developed a computer model to predict the effects of global warming on hillslope erosion. Other interests focus on how geomorphic parameters (eg, topography) influence chemical weathering rates through their control on hydrological processes. Dr. Gabet has also investigated how river channels process large pulses of sediment via field and experimental work.
