Dr. Manny Gabet

Manny Gabet in the field I'm a geomorphologist with a wide range of interests across a variety of spatial scales, from exploring how individual raindrops disturb soil particles to investigating the geomorphic evolution of mountain ranges. My general fields of interests include hillslope evolution, post-fire erosion, the causes and consequences of rockfall, the toxic legacy of hydraulic mining during the Gold Rush, glacial erosion, and the geologic evolution of the Sierra Nevada.

  • 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 (e.g., 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.
