“…Approximately 43.7 % of the Republic of Croatia's area consists of karst and fluviokarst relief (Bognar et al, 2012). Dolines are the most typical surface karst form, and also considered to be a diagnostic karst form (Ford, Williams, 2007).…”

Dolines are considered to be among the most prominent karst formations, which is why they can serve as diagnostic forms of karst. Their spatial distribution and density are important indicators of an area’s degree of karstification, as well as of an overall geomorphological development. The aim of this paper is to determine the spatial distribution and the density of dolines, and also to analyse the influence of geological structure and morphometric features of the terrain (hypsometry, slope inclination, relative relief) on the spatial distribution of dolines in the area of southeastern Velebit. Moreover, for the first time with regards to the Croatian karst, the spatial distribution of dolines was compared with the spatial distribution of entrances into caves in the southeastern Velebit’s area of Crnopac. The data on the dolines’ position were adopted from 1:25,000 scaled topographic maps. All data were digitalised and analysed with ArcGIS 10.1 software in the GIS laboratory of the Geographic Department of the Faculty of Science in Zagreb. The research showed a strong influence of morphometric parameters of the relief on dolines’ density. The most prominent occurrence of dolines is linked with the areas ranging from 1000 to 1200 meters of altitude, slope inclination lower than 2° and the relative relief of 100 – 200 m per km2. Furthermore, the highest density of dolines was recorded in the Jurassic carbonate layers, while it was determined that the zones of main faults do not have a significant influence on the increase of dolines’ density. A high degree of correlation was determined by comparing spatial distributions and density of dolines and entrances into caves.

“…Karst plateau region in Montenegro (Cvijić 1926;Petrović 1997) displays similar characteristic to other karst plateau areas in Dinaric karst (Gams 2004;Bognar et al 2012;Bočić et al 2015). More than a few tenths of square kilometers of Montenegrin karst plateau is lack of surface water and the overall precipitation tends to disappear into limestones lying below.…”

The most significant caves in Montenegro were distinguished in response to their physical-geographic, biological, archeological and morphometric characteristics (length and depth). Caves distribute in four distinctive regions: coastal karst, karst plateau (relict valley system), fluvial karst (recent hydrologic systems) and the high mountainous karst area. The most outstanding within the last, due to abundances of the major caves with depths from a few hundred meters to 1,162 m, are four mountain regions: Mt. Durmitor, Mt. Lovćen-Orjen, Mt. Maganik and Mt. Bjelič.

“…The total length of the coastline is 6176 km, of which the islands account for 4398 km (71%) and an area of c. 3259 km 2 -5.8% of the total Croatian land area (Croatian Ministry of the Sea, Transport and Infrastructure; Duplančić Leder et al 2004). The coastline is predominantly an erosional rocky one with scattered pocket beaches and accumulation of sediment only near river mouths (Bognar et al 2012). In the north of the Adriatic, the rivers flow through flysch geology susceptible to erosion and have carried large quantities of sediment into the sea.…”
