  Article:   DEUTERIUM ISOTOPIC CHARACTERIZATION OF PRECIPITATION WATER.

Authors:  .
 
       
         
  Abstract:  

This study was focussed on the analysis of isotopic compositions of hydrogen in samples from precipitation water. Stable isotope compositions of groundwater are principally controlled by the compositions of precipitation, evaporation, mixing of water mass and isotope fractionation with phases in the aquifer. The strong link between long-term monthly average values of the local surface air temperature and the deuterium abundance of precipitation fallen over Cluj-Napoca in the time period 1975-2004 was evidenced. These data are of large interest in studies of groundwater and water movement in wetland.
