Biokovo Mt is part of the Outer Dinarides, in a coastal position with a NW-SE main tectonic orientation. The highest peak called Sveti [Sv.] Jure (1762 m) towers above a karst plateau of 1300-1400 m mean elevation. Both of the long margins of Biokovo are characterized by steep and high relief energy rockwalls formed along tectonic fault lines. The plateau is intensely karstified with diverse karren forms, large dolines and several shaft caves. Its unique karstmorphological features are the relatively deep dolines with steep walls, so the landscape is characterized mainly by the sharp interdoline ridges and pyramidal peaks instead of negative doline forms. Based on the previous observation, the Biokovo plateau can be considered a "polygonal karst".The geomorphological map of a study area from this plateau has been elaborated, based on field observations and topographical maps. After digitizing the contour lines, we have created the digital elevation model (DEM) of the study area and carried out sophisticated doline-morphometrical analysis using the DEM. The most important and unique feature of the landscape, the polygonal structure, has been derived from the DEM using GIS hydrologic modelling tools.Key words: doline, polygonal karst, morphometrical analysis, Biokovo Mt. Morfometrijska analiza ponikava i krških reljefnih oblika Biokova (Hrvatska) temeljena na digitalnoj analizi reljefa i terenskom istraživanjuPlanina Biokovo nalazi se na obali Jadranskog mora i dio je Vanjskih Dinarida s tipičnim dinarskim smjerom pružanja SZ-JI. Najviši vrh Biokova Sv. Jure (1762 m) izdiže se iznad krške zaravni koja se nalazi na visini od 1300 do 1400 m. Sjeveroistočna i jugozapadna padina Biokova nastale su duž glavnih rasjeda, vrlo su strme i velike su reljefne energije. Krška zaravan građena je od jurskih i krednih vapnenaca i dolomita te je intenzivno okršena. To se očituje u bogatstvu krških reljefnih oblika: škrapa, vrlo velikih ponikava i jama. Posebnost su krškog reljefa Biokova duboke ponikve vrlo strmih padina, tako da je krajobraz istraživanog područja više obilježen oštrim i uskim grebenima i visokim piramidalnim vrhovima koji međusobno odjeljuju ponikve nego udubljenjima. Na temelju dosadašnjih istraživanja biokovsku kršku zaravan možemo smatrati "poligonalnim kršem". Na osnovi terenskoga kartiranja i različitih analiza topografse karte načinjena je geomorfološka karta istraživanog područja površine od 3 km 2 koje se nalazi jugozapadno od vrha Sv. Jure. Na temelju digitaliziranih izohipsa izrađen je digitalni model reljefa (DEM) istraživanog područja, koji je poslužio sofisticiranoj morfometrijskoj analizi ponikava. Poligonalna struktura dobivena je iz digitalnog modela reljefa uz pomoć GIS hidroloških alata.Ključne riječi: ponikve, poligonalni krš, morfometrijska analiza, Biokovo * isti rad je tiskan na mađarskom jeziku 2005. godine u KARSZTFEJLŐDÉS X.

“…This value can be considered as small to medium in a Dinarides context (e.g. Faivre and Reiffsteck, 1999;Faivre and Pahernik, 2007). Nevertheless, the dolines practically cover the whole surface so there are no wide and rounded interdoline hills and crests such as are found in typical lower elevation karst mountains (e.g.…”

“…For this purpose, the traditional method is used and the uppermost closed contour lines of depressions are delineated (Day, 1983;Denizman, 2003;Faivre and Pahernik, 2007;Telbisz et al, 2009;Benac et al, 2013;Bocic et al, 2015). The uppermost closed contour lines of 30,132 karstic depressions are digitized as polygons in a GIS framework and the morphometric properties of the polygons are calculated.…”

“…Limestones with more than 90% CaCO 3 (Nazik, 1986) and a thickness of up to 5000 m in the Taurus Mountain belt (Koçyiğit, 1984) resulted in appropriate lithologic conditions for depressions formed by the dissolution of limestone. Within the same lithologic unit, gently sloping karstic plateaus over 2000 m provide appropriate topographic conditions because depressions generally reach maximum density on the gentle slopes of high karstic plateaus (Plan and Decker, 2006;Faivre and Pahernik, 2007;Sauro, 2013;Daura et al, 2014;Bocic et al, 2015). Tectonic structure, especially fracture intensity and orientation, has a strong effect on doline development, density, and distribution on gently sloping high karstic plateaus (Car, 2001;Jemcov et al, 2001;Doctor and Doctor, 2012).…”

This study investigates the spatial distribution characteristics of karstic depressions that developed on a 2558 km 2 plateau with gently sloping in neritic (reef) limestones in the western section of the Bolkar Mountains. The 30,132 karstic depressions identified are located at elevations between 1315 and 2525 m, while 31°/km 2 slope and 5.6 km/km 2 drainage density are limited to the spatial distribution of depressions. In the central section of the study area at the anticlinal surface, maximum density (99 depressions/km 2 ) is reached between elevations of 1930 and 2080 m. The orientation of depressions is predominantly NE-SW. However, in the same area, the orientation of depressions also varies from ENE-WSW toward NE-SW from west to east. The left-lateral strike-slip Ecemiş Fault was effective in the formation of these orientations, with a NE-SW orientation close to the fault and ENE-WSW orientation farther away from the fault.

“…However, recent development in GIS techniques may contribute to a better understanding of karst landform evolution (e.g. Faivre & Pahernik 2007;Orndorff et al 2000;Plan & Decker 2006;Ravbar & Kovačič 2010;Telbisz 2010). Therefore, the aim of this study is not to give a geomorphological overview of Canin massif, but to quantitatively analyze and visualize the effects of different geomorphologic processes based on digital elevation models (DEMs), focusing mainly on the Italian side of the mountains.…”

IzvlečekUDK 911.2:551.432(234.323.6) Tamás Telbisz, László Mari & Lénárd Szabó: Geomorfološke značilnosti italijanske strani Kaninskega masiva (Julijske Alpe), ugotovljene z uporabo digitalnega modela reliefa in te� renskim opazovanjem V prispevku je na primeru Kaninskega masiva prikazano, kako z uporabo GIS tehnologij lahko preučujemo visokogorska kraška območja. Histogrami nadmorske višine in naklona na primeru Kanina kažejo na razlike med nivoji planot ter razlike v procesih med severnim, zahodnim in južnim delom pogo rja. Na osnovi karte grebenov in dolin, narejene iz digitalnega modela višin ter analize profila dolinskega dna smo potrdili pretekle spremembe smeri odvodnjavanja severnega dela Kanin ske planote. Na podlagi podatkov o naklonu smo določili potencialna območja akumulacije snega oz. snežišč in nunatakov. V okviru raziskave so bile narejene tudi skice geomorfoloških kart in statistična analiza zaprtih kotanj, ki nakazujejo na mlado površinsko zakrasevanje in močan vpliv geoloških struktur. Ugotavljamo, da so kvantitativne in vizualne zmogljivosti GIS-ov uporabne pri prepoznavanju vplivov ledeniških, fluvialnih, strukturnih in kraških procesov. Ključne beside: Kanin, digitalni model relief, glaciokras, GIS, vrtača, morfometrija. In this paper, by the example of Canin Massif, it is demonstrated, how GIS-techniques can be used for the study of high mountain karst terrains. In case of Canin, elevation and slope histograms show characteristic differences in plateau levels and landforming processes between the northern, western and southern sectors of the mountains. Ridge and valley map (derived from the digital elevation model) and thalweg analysis are used to recognize drainage reorganizations north of the Italian Canin plateau. Potential snow accumulation locations and nunataks are determined based mainly on the slope map. Geomorphological sketch maps and statistical analysis of closed depressions are also carried out in this study supporting the relatively young age of superficial karstification and the strong structural impact. Finally, it is concluded, that quantitative and visual capabilities of GIS are useful in discriminating the effects of glacial, fluvial, structural and karst processes.
