Abstract

The intriguing spatial variability of surface features on Krk Island has stimulated the research of this karst area located in the coastal zone of the Dinaric karst in Croatia. Field inspection, ortho-rectified aerial photos (0.5m resolution) and a topographic map (1:5,000) were used for the detection and delineation of detectable karst surface features appearing on the island with the area of 405.5 km². This method resulted in the identification of several yet undefined types of surface features occurring on karst, requiring the revision of the existing classification and re-establishment of a new classification system compatible with the particular field reality. Several morphologic and distributive parameters that had been calculated for each re-classified type of surface feature provided insight into the surface features elementary characteristics, their spatial variability and the correlation to the other types of surface features and to the recent karst relief. This analysis based on a large, accurate dataset, contributed to the general knowledge on karstic surface features, the conditions of surface features in Dinaric karst and to the understanding of the karst surface evolution on Krk Island.

Secondary abstract:	Raziskovalno delo na otoku Krku, ki se nahaja v obalnem delu Dinarskega krasa na Hrvaškem, je spodbudila nenavadna prostorska spremenljivost tamkajšnjih površinskih oblik. Kraške površinske oblike, ki se nahajajo na površini 405,5 km², so bile zaznane in očrtane s pomočjo terenskega dela, digitalnih ortofoto posnetkov v ločljivosti 0,5 m in topografske karte v merilu 1:5000. Tak pristop je omogočil zaznavanje več vrst še neevidentiranih površinskih oblik na krasu. To je spodbudilo prevetritev obstoječih klasifikacij ter vzpostavitev nove razvrstitve površinskih oblik, ki bolj ustreza stvarnosti dotičnega opazovanega območja. Več morfometričnih in distributivnih parametrov, ki so bili izračunani za posamezen tip na novo klasificiranih površinskih oblik, je omogočilo vpogled v njihove bistvene lastnosti, prostorsko spremenljivost in povezanost z ostalimi vrstami površinskih oblik ter trenutnim kraškim reliefom. Rezultati, ki so dobljeni iz obsežnega podatkovnega sloja s precejšnjo natančnostjo, so prispevali k splošnemu védenju o površinskih oblikah na krasu, k poznavanju površinskih oblik v pogojih Dinarskega krasa in k razumevanju razvoja kraškega površja na otoku Krku.
