Sažetak
Karst plateaus generally have a complex geological and geomorphological evolution. One of the largest plateaus in the Dinaric karst is Una-Korana plateau extends along the northeastern edge of the Dinarides. Provides the Dinaric direction (NW-SE) across three countries: Slovenia, Croatia and Bosnia-Herzegovina with a length of 120 km. Width is 10 to 20 km, and the area is about 1800 km2. It is mostly built of Mesozoic carbonate rocks of the Adriatic carbonate platform, and main structures and faults extend Dinaric direction. The main morphological characteristic is flatness in the macro level. Because of the carbonate rocks, area is highly karstified. In micromorphological sense dolines prevail (with high density) on the surface and caves in the underground. Area intersected five major rivers which are cut in deep canyons and have no major tributaries. On the entire area, more or less preserved, traces of surface paleohydrographic networks were observed. The aim of the study was to reconstruct and analyze paleohydrographic network and recent features to know about its evolution, impact and development of karstification of this karst plateau. With the methods of field work we also analyzed the data from topographic maps 1:25.000. Analysis of data was performed with the GIS tools. For the first time we reconstructed paleohydrographic network in this area, we analyzed its hydromorphometry, paleo and recent network relationship with geological, structural and karst characteristics of the area and finally its morphoevolution.
