Research Projects

There are 15 sub-projects within the ENIGMA ITN. They are organized in different work packages around the overarching question: “How to adapt subsurface imaging strategies to the processes of interest?”

  • work package “Explore coupled dynamic processes in highly instrumented sites”
  • work package “Enhance our capacity to monitor temporal changes in the spatial distribution of subsurface water content and fluxes”
  • work package “Create new methods for tracking the transport and reactivity of chemical species in subsurface fluids”
  • work package “Design inverse modelling strategies for imaging dynamic processes in complex subsurface structures”

An additionnal work package is dedicated to ESR training. Please click on any of the below to find out more about the individual projects.
