Kanjonska dolina reke Rakitnice je ena izmed najglobljih in najdaljših na Dinarskem krasu. Prispevek obravnava osnovne morfološke in morfostrukturne značilnosti kanjonske doline in njeno ...geomorfološko regionalizacijo. Poudarjena je zlasti močna povezava med litologijo, tektoniko in reliefom, saj so znatno vlogo pri razvoju te reliefne oblike odigrali zlasti neotektonski procesi v kvartarju. The canyon valley of the Rakitnica river is one of the deepest and longest in the Dinaric karst. The paper states the basic morphological and morphostructural characteristics of the canyon, and gives its geomorphological regionalization. High level of correlation between lithology, tectonics and relief of the researched area has been determined. Genesis and development of this relief form have been considerably guided by neotectonic processes during the Quaternary.
The researched area of the mountain massif Prenj with surface of 463 km2 is located in the zone of high karst of Outer Dinarides of Bosnia and Herzegovina. It is circular mountain morphostructure ...with assymetrical transversal profile. Developed in Mesozoic subhorizontal layers of limestone and dolomite over 3500 thick, fissured by numerous reverse and normal faults. Prenj is folded-thrusted mountain massif (2103 m a.s.l.) uplifted during neotectonic phase of Dinarides development, structurally represented by three blocks. A high degree of correlation between lithology, fault structures and relief has been determinated. The main fault structures caused by rotation of Prenj blocks which were reflected on different orientations of stretching of the mountain ridges and composite valleys of Neretva, Konjièka Bijela, Mostarska Bijela, Glogo¹nica and Id-bar. Thrusts express tectonic, lithological, and morphological border of the considered mountain with inter mountain Neogene depressions in the North and South. Netectonic movements and dominanting carbonate composition of the terrain have influenced on reticular relief structure of the massif. Linear landforms of ridges formed in karst are neotectonically, rectilinearly and half-arc elongated up to 12 km. In regards to morphogenesis during the Quaternary, the massif is characterized by development: derasional, glacial, periglacial, karstic, fluviokarstic, fluviodenudational and fluvial erosional and accumulational processes and landforms. Finally, geomorphological regionalization of Prenj was made on the basis of the criteria of similarity of morpho-evolutionary, structural-lithological and orographical characteristics.
This research analyses the genesis of eleven inner gorges that morphologically constitute the lower parts of the Rakitnica Canyon Valley in the Central Dinarides of Bosnia and Herzegovina. The ...spatial distribution of these 300 m deep fluviokarstic landforms, geomorphically reshaped
in a thick, brittle Triassic dolomite and limestone, is directly related to contractional restraining bends of right lateral strike-slip faults. The origin and development of most of the Rakitnica's inner gorges was tectonically directed and controlled by pre-existing subvertical tensional
gashes, which is confirmed on the basis of their close position to parent dextral strike-slip faults, orientation of its direction, the sigmoidal shape of the gorge's riverbed and hackles on the lower, intact sides of longer gorges. The morpho-evolution of these narrowest parts of the canyon
valley, from Upper Pleistocene to recent time, is characterized by simultaneous transpressional uplifting of the terrain and fluvial downcutting across secondary joint fractures mode I opening.
Gornja dolina Une po svojim specifičnim i atraktivnim prirodnim značajkama već odavno zaslužuje epitet zaštičenog područja. Zbog toga je u posljednje vrijeme pokrenuta procedura proglašenja ...Nacionalnog parka “Una”.
U ovome radu na temelju predhodnih terenskih opservacija i izvršenog geomorfološkog kartiranja provedeno je geoekološko vrednovanje reljefnih oblika metodom indeksa rekreacijskog potencijala. Time je s prostorno-planerskog stanovišta omogućena daljnja valorizacija područja. Istaknute su smjernice buduće namjene prostora NP “Una” (zoniranje, regionalno povezivanje) i prirodne predispozicije za razvoj određenih vidova turizma i rekreacije. Posebno su naglašene neophodne mjere zaštite kojima bi se otklonili sadašnji negativni antropogeni utjecaji u gornjem poriječju Une.
