Sažetak
The investigated area comprises the north western part of Mt. "Ivančica", which is located at north western Croatia. It is composed of rocks ranging in age from Paleozoic to Quaternary. However, from hydrogeological point of view, Triassic carbonate deposits are particularly important because of great amounts of accumulated groundwater which is used for public water supply of surrounding areas. Detailed hydrogeological research of the catchment area of four spirngs - "Žgano vino", "Bistrica", "Šumi" and "Beli zdenci", was carried out in 2007 and 2008 for the purpose of defining groundwater source protection zones. Apart from hydrogeological mapping, which was performed to spatially separate carbonate aquifer from aquitards and aquicludes, the spring discharge capacities were also measured on several occasions and spring groundwater samples were taken in different hydrological conditions of aquifer for chemical analyses. The results have pointed to different hydrodynamic and hydrochemical features of groundwater at catchment areas of investigated springs, which enabled different approaches to delineation of groundwater protection zones. The study is a good example of methods for groundwater source protection zones delineation in fissured-karstic aquifers, in situations where tracer tests cannot be applied in order to estimate mean groundwater velocities which are subsequently used for dimensioning of protection zones.
