δ18O SPATIAL DISTRIBUTION OF PRECIPITATION IN CROATIA

The precipitation as the input into the water system and its stable isotope composition is a basic part whose knowledge is required for proper use and management of water resources. The geomorphology of Croatia (e.g., high mountains next to the sea) can cause specific local conditions. We have monitored the stable isotopic composition (δ18O and δ2H) of precipitation in more than 25 stations in various locations at different altitudes. For the work reported here, only those data sets are used that span at least one year, altogether 22 stations. The δ18O, δ2H and d-excess altitude effects have been extracted from the measured data base of precipitation isotope ratios. This data base has been used to produce a gridded map of δ18O for Croatia.
