Abstract

U radu su metodama terenskog rada, daljinskih istraživanja i analizom arhivskog materijala istražena geomorfološka obilježja, evolucija i ranjivost 47 žala na otoku Hvaru. Većina žala, njih 85,1 %, čini geomorfološke sustave s drenažnim bazenima i oblikovana su u plavinskom materijalu na njihovom ušću, 8,5 % žala oblikovano je ispod klifa, dok je najmanje, njih 6,4 % oblikovano u eolskim naslagama. U posljednjih 200 godina žala su izgubila prosječno 44,1 % svoje površine, dok im se obalna linija pomaka prema kopnu za prosječno 5,5 m. Procjena ranjivosti žala pokazala je da je većina žala na otoku Hvaru jako ranjiva te teži prema vrlo jakoj ranjivosti, što se podudara sa značajnim trendom erozije žala tijekom posljednjih ~200 godina te naglašava potrebu za održivim upravljanjem žalima i stalnim praćenjem stanja.

Abstract (english)

This thesis investigates the geomorphological properties, evolution, and vulnerability of 47 beaches on the island of Hvar using fieldwork methods, remote sensing, and analysis of archival material. The majority of the beaches, 85.1%, are part of geomorphological systems with drainage basins and are formed in alluvial material at their outlets, 8.5% are formed beneath cliffs, while the smallest portion, 6.4%, are shaped in aeolian deposits. In the last 200 years, the beaches have lost an average of 44.1% of their surface area, and their shoreline has retreated landward by an average of 5.5 meters. The vulnerability assessment shows that most beaches on the island of Hvar are highly vulnerable and tend toward very high vulnerability, which corresponds to the significant trend of beach erosion over the last ~200 years, highlighting the need for sustainable beach management and continuous monitoring.
