Protection of karst aquifers in the Dinarides in Croatia

This paper presents karst water protection measures being introduced in the Dinarides of Croatia. The spring sites for the water supply of the town of Rijeka, for its 200 000 inhabitants and the largest harbour of the northeastern side of the Adriatic Sea, have been used as a pilot research area. The European research project was used, and protection of water was generally divided into three phases. A categorisation of springs has been made, and five basic protection zones have been distinguished. The rules of behaviour in protected zones have been outlined. For the firs time, the term water-supply "reserve" has been introduced, referring to the parts of the mountainous region where karst groundwater is recharged.
