Sažetak
The study analyses fluvial deposition (sedimentation) in groyne fields constructed on the meandering section of the Danube River from Novi Sad (Republic of Serbia) to the border of the Republic of Croatia, the Republic of Serbia and Hungary (1255 ÷ 1433 km stations). By processing satellite images (Google Earth) of the studied area, groyne systems were detected at 25 locations and their characteristics and sedimentation by the river deposited materials were elaborated on more than 100 groyne fields. Results show that on the observed groyne fields and systems, the new areas, formed by fluvial deposition, are overspread on totally over 5,5 million m2 (cca 3,13 million m2 on the left and 2,38 million m2 on the right riverside). Distribution of groyne fields more affected by fluvial sediments was substantially greater on the left (~60 %) than on the right (~40 %) Danube riverside. On predominant portion of the groyne systems (15/25) fluvial sedimentation occupied 40 ÷ 80 % of the total groyne field area.
