Sažetak
In the article are presented the geomorphological features of the region of Northern Velebit with a special emphasis on the Northern Velebit National Park. The fundamental morphometric and morphogenetic analyses once done analogously were made with the use of digital technologies
and supplemented with new analyses and fieldwork. Of the general morphometric methods,
hypsometry, the analysis of the gradient of the slopes, the analysis of the vertical division and the exposure of the slopes were used. The morphogenetic analysis is based on specific morphometric
and field investigations. Within the framework of the morphogenesis the morphostructural relief was analysed, and of the exogenous influences, the greatest attention was dedicated to the karstic, glacio-karstic and fluvio-karstic relief forms. The analysis of the karst relief in the Northern Velebit National Park region, one of the fundamental phenomena of the park, showed that more than half of its surface area (50.6%) is represented by karst depressions (sinkholes and valleys) which speaks
of an exceptionally powerful and long-lasting denudation. Along with the karst processes, glacial processes which at that time of the last glacial maximum considerably reshaped the karst relief forms and generally influenced the geomorphological evolution of Northern Velebit contributed
significantly to the increased denudation. The glaciation of Northern Velebit, apart from the karst reliefs occasionally influenced the intensification of fluvial and the existence of limnic processes.
Therefore, the knowledge of the geomorphological features of Northern Velebit and the Northern Velebit National Park is of extreme significance both for the preservation of geodiversity and for its further touristic valorisation and promotion.
