Sažetak
Dugi otok Island is the largest and the longest island of Zadar Archipelago, situated in central part of the Adriatic Sea in Croatia. The island extends in Dinaric, i.e. NW-SE direction and it is parallel with relief and geological structures of the neighbouring mainland. Such parallelism of the islands is known as Dalmatian type of coast. The coastline is primary the result of the Late Pleistocene-Holocene sea ingression. The island is predominantly composed of karstified carbonate rocks from Cretaceous period. Basic geomorphological characteristics of the island are concordance of orography with geological structure, and the predominance of karst. There are no surface water flows, but there is presence of groundwater. The main aim of this study was to explore and define the impact of fluvial processes on valleys, dry valleys, and coves and bays, which reveal the existence of paleorivers. Their formation is connected with regional climate conditions of this area during Pleistocene, especially during the Last Glacial Maximum. Furthermore, breccia, lacustrine sediments and terra rossa, which occur in the researched area, indicate the fluvial origin of valleys and other geomorphologic shapes.
