Field investigations on the island of Vis have been conducted since September 2019. More than a year of on-going research include: 

  • Determination of hydraulic parameters of the karst aquifer – water levels, aquifer dynamics
  • Monitoring of hydrochemical parameters – EC, pH, temperature, oxygen content, and basic ion composition
  • Groundwater and spring water sampling
  • Stable and unstable isotope analyses – hydrogen, oxygen, and sulphur 
  • Geophysical research - seismic, magnetotelluric and electrical resistivity tomography methods
  • Structural measurements – detailed fault and fracture network analyses
  • Initial steps for 3D model – conceptual model.
