Sažetak
Hydrogeological investigations using hydrochemical and isotopic methods have been performed to determine the sanitary protection areas of springs in the drainage area of the Vransko Polje near Biograd (North Dalmatia) and main springs in the drainage area of the Gacka River (Lika region). Both regions are situated in the karst area of Croatia. Water samples from springs and precipitation samples at both areas were collected monthly in the period 2005-2006. Hydrochemical results follow the variations caused by the main hydrogeological properties of particular aquifer and recharge conditions during different seasonal hydrologic and vegetation conditions. The mean 3H activity in all main springs in the Gacka River area is similar to that of precipitation, while in the springs of Vransko Polje the mean 3H activity is lower if compared with precipitation due to sea water infiltration. There is no seasonal fluctuation of 3H activity in all springs indicating fast circulation and good mixing of precipitation and ground waters.
