DESCRIPTION:Dr Sara Bonetti\, Tenure Track Assistant professor\, Laborator
 y of Catchment Hydrology and Geomorphology (CHANGE)\, ALPOLE-Sion\nAbstrac
 t:\nCatchments are natural integrators of a number of ecohydrological and 
 geomorphological processes and providers of key ecosystem services. Yet\, 
 in light of the complex interactions of multiple biotic and abiotic proces
 ses acting at different spatio-temporal scales\, our ability to describe c
 atchment dynamics is still limited. This is particularly evident when clim
 atic and anthropogenic disturbances affect the natural evolution of a land
 scape. Among the multiple factors shaping the development and functioning 
 of a watershed\, vegetation plays a key role in the regulation of water in
 filtration and overland flow\, with repercussions on soil erosional proces
 s as well as carbon and nutrient fluxes. Here\, I will discuss the role of
  soil\, vegetation attributes\, climatic conditions\, and their spatial ar
 rangement in shaping ecohydrological fluxes and erosional processes at dif
 ferent scales. I will focus on the contrasting features of natural and int
 ensively managed landscapes to discuss efforts and opportunities in the an
 alysis of anthropogenic disturbances and their impacts on water\, carbon\,
  and sediment fluxes. Progress on this front is paramount to foresee the c
 onsequences of climate and land use change\, devise optimal land managemen
 t strategies\, and avoid critical transitions to unsustainable conditions.
 \n\nShort biography:\nSara Bonetti joined EPFL in September 2022 as a tenu
 re track assistant professor in Catchment Hydrology and Geomorphology. Bef
 ore joining EPFL\, she was an assistant professor at the Soil Physics and 
 Land Management Group at Wageningen University (the Netherlands). She rece
 ived a BSc degree in 2009 and a MSc degree in 2011 in Civil Engineering\, 
 both from the University of Padova (Italy). From 2012 to 2014 she was a re
 search assistant\, first at Duke University (USA) and then at the Universi
 ty of Padova (Italy). In 2018\, she obtained her PhD in Civil and Environm
 ental Engineering from Duke University\, with a doctoral dissertation on t
 he analysis and modelling of landscape evolution and soil erosion. From Au
 gust 2018 to July 2020\, she was a postdoctoral associate at the Soil and 
 Terrestrial Environmental Physics group at ETH Zurich (Switzerland) and\, 
 from March 2020 to September 2021\, she worked as a research fellow at the
  Institute for Sustainable Resources at University College London (UK). He
 r work focuses on the development of quantitative tools for the descriptio
 n of coupled ecohydrological and geomorphological processes in natural and
  managed ecosystems.
