Sažetak
The determination of the catchement boundaries and the catchment areas is starting point in all hydrological and hydrogeological analyses. For water circulation in karst, this classical hydrologic problem, represents extremely complex, sometimes not easily solved, task. Physical and chemical processes in karst terrains, accompanied by tectonic movements and strong influence of man’s interventions have formed well-linked fissure systems in karst massifs. While considering determination of catchment area in karst one should bear in mind that the karstification process, i.e. the solution and redistribution of surface and subsurface karst features is a continual process which cannot be stopped. Generally, the time unit of these changes is relatively long when compared with the human life, but it is very short when compared with the geological time scale. The catchment areas in karst vary according to the groundwater levels change with time. It should be stressed that human interventions, especially construction of dams and reservoirs, can introduce instantaneous and definite changes in catchment boundaries. In paper some examples are given. The paper researches influence of different factors on the evolution of karst catchment.
