| Popis: | The doline density and their spatial distribution analysis is one of the methods used for karst relief morphostructural analysis. We present the results of morphometric features, doline spatial distribution and their relationship on Miljevci karst plateau based on digital elevation model (DEM). Altogether, 286 dolines were mapped in the study area. The doline density analysis has been applied. The results show that the doline spatial distribution is clustered. Two larger areas with densities of 30 and 34 dolines/km2 are determined. Their distribution along the river canyons could indicate the existence of a palaeodrainage network. The strongest link between the doline density and topography is with inclination and vertical relief dissection, whereas the number of dolines decreases with an increase of slope inclination and relative relief. Such distribution confirms the suitability of karstic plateaus without active drainage for doline formation. |
