20.500.12556/RUL-156135 Analysis of karst surface anisotropy using directional semivariograms, Slovenia The paper presents a study of the anisotropic properties of the karst surface through the use of semivariograms. Karst is formed by hydrogeological and tectonic deformations that determine the surface and subsurface characteristics of the area. Among the most prominent surface features are dolines, which generally form in a linear direction. Semivariograms can be used to determine both the preferred direction of anisotropy and the degree of anisotropy. The surface exhibits the greatest elevation variability in the direction of the most diverse terrain, corresponding to dolines. The results, based on the eight karst areas studied, show that it is possible to detect and, more importantly, quantify anisotropy in all karst areas, although in some cases it is impossible or difficult to detect visually. The directions of the semivariograms agree very well with those obtained from the visual inspection of the maps, as well as with the orientations of the main faults. The method is therefore very useful for quantitative determination of anisotropy and its interpretation could be greatly improved by using the detailed structural geological maps of the karst. karst dolines anisotropy semivariogram surface variability Slovenia true false true Angleški jezik Ni določen Članek v reviji 2024-05-10 10:10:31 2024-05-10 10:10:31 2024-05-11 03:58:06 0000-00-00 00:00:00 2024 0 0 Str. 233-245 iss. 1 Vol. 181 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 55 0033-4553 10.1007/s00024-023-03411-x 180385027 s00024-023-03411-x.pdf s00024-023-03411-x.pdf 1 52D44A7CE96986B6246AB2CE1A5D9DBA 0a5d3ca75b1f3a3c74a866c3181cbe89e59ecb960760881dbc4f042726968af0 84f113a1-0ea5-11ef-99d3-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=183419 https://link.springer.com/article/10.1007/s00024-023-03411-x 0 ff87b965-0ea4-11ef-99d3-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=183418 Naravoslovnotehniška fakulteta 0 0 0
