Abstract

U radu su analizirana geomorfološka obilježja žala otoka Hvara. Primjenom metoda terenskog kartiranja, analize satelitskih snimaka te metoda analize i vizualizacije u GIS-u utvrđeno je da otok Hvar ima 247 žala koja čine 3,2 % ukupne duljine obale. Najveći broj žala formiran je u proluvijalnom materijalu na ušćima jednostavnih i složenih jaruga te se stoga očekuje međusobna povezanost veličine drenažnog bazena i površine žala. Žala otoka Hvara su izrazito malena. Samo 9 žala ima površinu veću od 1000 m2, a čak njih 86% je površinom manje od 500 m2. Korelacija između površine drenažnih bazena i svih žala oblikovanih u proluvijalnim plavinama je umjerena, (r=0,61). Međutim, ukoliko se u obzir uzmu samo žala bez antropogenih utjecaja tada korelacija postaje značajna (r=0.8). U radu se također diferenciraju žala oblikovana ispod klifova, žala oblikovana u pijescima eolskog podrijetla te antropogeno formirana žala.

Abstract (english)

The thesis deals with geomorphological properties of the island of Hvar beaches. By means of field mapping, satelite images analyses and visualisation in GIS, it was found out that there are 247 beaches on the island of Hvar. The beaches relate to 3,8 % of the total coastal length. Majority of the beaches are formed in proluvial fan material at the mouth of torrent valleys so the correlation between drainage basin area and beach area is expected. Beaches on the island of Hvar are mostly small. There are only 9 beaches with area bigger than 1000 m2. 86% of the total amount of beaches are smaller than 500m2. The correlation between drainage basin and beach area is moderate (r=0,61). However, if only the beaches without any anthropogenic impact are considered, the correlation becomes significant (r=0,8). Beaches formed under the cliff, beaches formed in aeolian sediments and anthropogenic beaches were also differentiated.
