Abstract

U razdoblju od 1951. do 2023. godine analizirane su morfološke promjene triju žala: Plišivac, Minerva i Frara na području Makarskog primorja. Analize su temeljene na satelitskim (Google Earth) i ortofoto snimkama (DGU), a načinjene su u ArcGIS Pro i Agisoft softwareu. Analize su pokazale značajne promjene površina žala Plišivac tijekom posljednjih ~70-tak godina, u rasponu od 2 434,54 m2 do 3 958,83 m2 kod žala Plišivac, a od 452,32 m2 do 3 465,85 m2 kod žala Minerva. U istom razdoblju, žalo Frara bilježi samo manje promjene površine, od 825,08 m2 do 1181,1 m2. Razlog različite morfodinamike istraživanih žala je u značajnim antropogenim utjecajima na žalima Plišivac i Minerva gdje je došlo do višekratnih dohranjivanja žala, dok je žalo Frara nedostupno i potpuno prirodno. Osim faza naglog rasta površina žala, što možemo povezati s fazama dohranjivanja, analize pokazuju i epizode erozije koje su slijedile nakon dohranjivanja žala. Zbog dostupnosti velikog broja snimaka s poznatim datumom snimanja Google Earth snimke imale su najveći značaj u analizi promjena površine žala na istraživanom području.

Abstract (english)

In the period from 1951 to 2023, the morphological changes of three beaches: Plišivac, Minerva and Frara were analysed in the Makarska littoral. The analyses are based on satellite (Google Earth) and orthophoto images (State Geodetic Administration) and were made in ArcGIS Pro and Agisoft software. The analyses have shown that the area of Plišivac beach has changed significantly in the last ~ 70 years, from 2,434.54 m2 to 3,958.83 m2 on Plišivac beach and from 452.32 m2 to 3,465.85 m2 on Minerva beach. In the same period, Frara beach showed only minor changes, from 825.08 m2 to 1181.1 m2. The reason for the different morphodynamics of the studied beaches is the significant anthropogenic influence on Plišivac and Minerva beaches, where there have been repeated nourishments, while Frara beach is inaccessible and completely natural. In addition to the phases of sudden growth of the beach surface, which we can associate with phases of nourishments, the analyses also show episodes of beach erosion that followed. Due to the availability of a large number of images with a known date of acquisition, the Google Earth records had the greatest importance in the analysis of morphological changes of beaches in the studied area.
