Sažetak
Hydrogeological researches which are performed to determine sanitary protection zones are not adequate to cover every part of the terrain comprised in those zones. Zones determined by minimal investigation works may be taken as a basis, and for the terrain inside the zones there are protection measures and limitations of land use set by Croatian legislation Directives (Narodne novine 55/02 ; Vlahović, 2003). For certain uses of land inside sanitary protection zones, the directives leave a possibility called "micro zoning". This is needed to carry out hydrogeological researches at an exact location, in a "micro zone". Based on the results, an evaluation of the sensitivity on the micro location can be given, and of its suitability for use in the way applied for. New protection measures and limitations may be prescribed for that exact location. It is well known that protection of karst terrains differs from one case study to another (Bahun, 1989). Dinaric karst in Croatia (Fig. 1) is characterized by very deep and irregular karstification, mainly predisposed by tectonics, compression, reverse faults and overthrusting structures. The structures are additionally neotectonically disturbed because of the change of stress direction from approximately NE-SW to N-S. Otherwise the Dinaric karst is a well-known “ locus typicus” and many internationally accepted terms in karst hydrogeology originate from the Dinaric karst area. Nevertheless, Dinaric karst differs from region to region and it can be distinguished into many types. For example, the karst on the Adriatic islands differs from the karst in the Ravni Kotari area near Zadar, and is completely different from the karst in the Lika region. That difference is both morphological and hydrogeological. The protection model for each kind of aquifer needs to be adjusted to the natural conditions.
