Areas of interest

Application of hydrochemical parameter: rare earth elements incl. Y, stable isotopes (δ18O, δ2H, δ34S, δ13C), radioactive isotopes (tritium, radiocarbon), major- and trace elements (Cs, Rb, U, Br) to identifiy temporal and spatial dynamic of:

  • Groundwater-resources under semiarid and arid climate conditions
  • interaction of surface- and groundwater bodies
  • interaquifer-flow
  • vulnerability of water bodies in respect to geogene and anthropogene contaminants
  • water-rock-interaction
  • geo-bio-interactions in groundwater systems
