Morphometric classification and spatial distribution of dolines in southern Slovenia

2025-01-29T06:58:53+01:00

Dolines have traditionally been classified based on qualitative descriptions. This research presents the first attempt to connect a morphometric classification of dolines with existing morphological typologies in Slovenia. Using an automatic detection algorithm on a digital elevation model, we identified 179,288 standalone dolines and classified them into four classes based on morphometric characteristics. The classes were interpreted using statistical and spatial analyses. Dolines in Slovenia can be grouped into bowl-, funnel-, well-shaped, and elongated types. The type and distribution of dolines reflect the properties of karst, particularly sediment coverage and cone karst features. This research marks an initial step toward the systematic study of dolines, laying a foundation for further research.

Reconstruction of palaeoflow and depositional dynamics from the Merjasec unroofed cave, Laze Plain (central Slovenia)

Sparsely preserved unroofed cave deposits are ancient remains of cave systems. The Merjasec unroofed cave is a perfect example of poorly preserved cave deposits where conventional sedimentological study revealed a greater potential for the reconstruction of local to regional palaeoenvironmental conditions. Cave deposits are characterised by polymictic conglomerates, pebbly sandstones and flowstone belonging to five distinct sedimentary facies. Sedimentary features indicate deposition of channel-related bedforms in a narrow cave-connecting conduit, activated only during extreme pulsating floods under epiphreatic conditions. In this sense, it mimics the current hydrology of the regional system and shows that the hydrological history of the cave system is strongly dependent on climatic conditions. Moreover, this study demonstrates a methodological approach that can be successfully applied to similary exposed cave deposits elsewhere, showing that even fragmentary or eroded remnants, when analysed in detail, can significantly contribute to understanding of karst palaeohydrology.

Spatial distribution of social innovation potential in disadvantaged areas: The case of two Hungarian counties

2025-07-21T07:18:19+02:00

Social innovation has emerged as a strategic tool to foster development in disadvantaged areas. The study analyzes the spatial distribution and temporal changes of social innovation potential and its link to population dynamics in two disadvantaged Hungarian counties. Using indicators classified into input, output, and impact categories, a composite index was constructed for municipalities over three census years (2001, 2011, 2022). Moran I statistics and clustering tested spatial dependence of social innovation potential and the relationship between clusters and migration balance. Findings show positive spatial autocorrelation weakened over time. A strong link exists between social innovation potential and migration balance, with innovative settlements showing lower outmigration.
