DESCRIPTION:Dr Elham Rouholahnejad Freund\n10:30 – 11:15 – Dr E. Rouho
 lahnejad Freund\nSenior Scientist at ETHZ\, Switzerland\n\nHydrological pr
 edictions in an era of change: chances and challenges\n\nWater is in conti
 nuous cycle on planet Earth and sustains life. Climate change and populati
 on growth are great threats to this hydrological cycle. It is unclear how 
 the dynamics of subsurface water storage and release\, the seasonal origin
 s and turnover time of water used by plants\, and plant water uptake depth
 s will be impacted when environmental conditions change (e.g. receding gro
 undwater\, more frequent droughts). Reliable predictions of these hydrolog
 ical fluxes and their interactions and feedbacks to the atmosphere have im
 portant implications for predictions of future near-surface climate and ve
 getation resilience in a changing climate. Despite their critical importan
 ce\, hydrological fluxes are often estimated with large uncertainties (e.g
 . evapotranspiration fluxes) owing to the complexity of the processes invo
 lved and the heterogeneity of land surface and subsurface. In this lecture
 \, I will highlight the current gaps in land surface models\, namely overl
 ooking of land surface heterogeneity and groundwater dynamics\, and will a
 ddress potential ways to correct for them. Furthermore\, I will discuss fu
 ture directions towards reliable prediction of hydrological fluxes at the 
 interface of ecosystem and atmosphere in a coupled soil-vegetation-atmosph
 ere observation and modeling framework.\n\nShort bio:\nElham Rouholahnejad
  Freund (1983) obtained her MSc in Civil Engineering in 2009 in Tehran\, I
 ran. She received her PhD in Large Scale Hydrology from ETH Zürich in 201
 4. She was awarded several fellowships from Swiss National Science Foundat
 ion and European Union and spent the last 4 years at Universities of Ghent
 -Belgium\, Freiburg-Germany\, and UC Berkeley-USA. She is currently a seni
 or scientist at ETH Zurich. The overarching theme of her research is to ad
 vance our understanding of water cycle dynamics and their complex interact
 ions with vegetation and the atmosphere in a changing climate.
