Sažetak
Hydrological and hydrogeological investigations of the karst river Rječina (Croatia), which has outflow in the Adriatic Sea, is presented. The paper treats a complex case o1 surface and groundwater circulation in a typical Dinaric karst catchment, which whole area is about 400 km2. In average 1500 1/s of karst groundwater in the catchment is used for water supply. On the central part of the Rječina River the Valići dam and reservoir for hydropower production are constructed. Both of mentioned reasons, as many others natural and anthropogenic, influenced strong changes of hydrological regime on the Rječina River and catchment. In paper special attention is paid on the analyses of the hydrological behaviour of the Rječina karst spring. Its exit is at the altitude of 325 m a. s. l., and mean annual discharge is 7.14 m3/s. The natural and anthropogenic influences on the decreasing of the Rječina spring discharges during the 1947-2003 period are explained.
