Extreme Vadose Zone (co-organized) 
Convener: Jan Vanderborght  | Co-conveners: Nicholas Jarvis , Nunzio Romano 
The summer of 2018 broke several long term meteorological records in several parts of Europe. In this session, we would like to discuss how these extreme weather conditions led to extreme conditions in the vadose zone and how these extreme conditions affected vadose zone processes and functions. Therefore, we invite for contributions that report on observations of vadose zone conditions and processes from soil observation networks, lysimeter stations, ecotrons, … , during years with extreme meteorological conditions. These observations are important to evaluate the impact of extreme meteorological conditions on soil processes, elucidate the interactions between soil, vegetation, and climate, and understand how changes in climate, with an anticipated increase in extreme conditions, will affect soil processes and ecosystem functions/services. Also studies that try to predict the impact of extreme meteorological conditions on vadose zone conditions, processes, and functioning and that identify knowledge gaps are solicited.
