“…The topography of the drainage basin is an important parameter for controlling the hydrological conditions associated with the gullying on particular area (Faivre et al, 2011). Slopes of 12 to 32° are extremely susceptible for gullying processes, while the higher inclines, which are predominantly present in the peak area, and are more conducive to rock slide and rock fall, that is to collapse processes (Fig.…”

“…Numerous changes can be observed today along the eastern Adriatic coast e.g. ice melting in mountainous speleological objects (Ledenica in Štirovača, Boi et al, 2012), sea level rise (Faivre et al, 2013;Faivre, Butorac, in press), floods as a result of precipitation extremes (Abdulaj et al, 2014;Gaji-Čapka, Cindri, 2014), frequent gullying (Faivre et al, 2011), frequent storms and storm surges (Meugorac et al, 2015), activation of landslides (Faivre et al, 2013;Mihali et al, 2017) and many others.…”

“…However, a very important factor of beach morphology is also the dynamics of gullying, which is becoming more and more intense and more frequent, and thus greatly affects the morphology of many beaches (e.g. Faivre et al, 2011).…”

“…Even if there are different kind of beaches along the eastern Adriatic coast (see e.g. Pikelj, Jurai, 2013;Marriner et al, 2014;Ruži et al, 2014), a large number of beaches is formed in proluvial material of small valleys and gullies (ravines) (Jurai et al, 2009;Faivre et al, 2011;Ruži et al, 2011). The occasional streams bring the material out of the drainage basin and create fans in which the beaches are formed in the contact with the sea.…”

U radu je analiziran geomorfološki sustav koji čine jaruga i žalo Zogon na otoku Hvaru s ciljem diferenciranja prirodnih i antropogenih procesa koji utječu na promjene žala. Primjenom metoda ponovljene fotografije, orto-foto snimaka i terenskog kartiranja ustanovljeno je da se u razdoblju od 60-ih godina 20. stoljeća do danas površina žala Zogon smanjila za oko 50 %. Smanjenje žala može se povezati s recentnim antropogenim djelatnostima na širem području istraživanja, osobito višestrukim nasipavanjem korita jaruge prilikom gradnje te manjim promjenama u korištenju zemljišta i prirodnom regeneracijom vegetacije što uzrokuje smanjenje dohrane žala. S druge strane, preokret u evoluciji žala u promatranom razdoblju, koje je po definiciji akumulacijski reljefni oblik, iz akumulacijskog ili stanja ravnoteže u stanje dominantne erozije možemo povezati s recentnim klimatskim promjenama i izdizanjem relativne morske razine. KLJUČNE RIJEČI: žalo, jaruga, obalna geomorfologija, promjene zemljišnog pokrova, promjene korištenja zemljišta, klimatske promjene, vinogradarstvo, Sveta NedjeljaThe geomorphological system composed of a torrent and a beach on the Island of Hvar was analysed with the aim to define natural and anthropogenic processes which influence changes in beach morphology. Using repeat photography method, ortho-photo images and field mapping it was found that between the 60s of the last century and the present, the Zogon beach reduced in size by approximately 50%. The reduction of the beach size can be related to the recent anthropological activities in the wider study area particularly due to multiply filling of the torrent bed during construction works and minor land use changes, as well as due to natural reforestation which all cause a decrease in the supply of material to the beach. On the other hand, the reversal of the beach evolution in the observed period, which is, by definition the accumulative relief form, from the accumulative state or state of balance, to dominant erosion, can be associated with recent climate change and relative sea level rise. 166 UVODRecentne klimatske promjene veliki su problem današnjice te su stoga i česta istraživačka tema. Najbolje se uočavaju na područjima koje čovjek dobro poznaje ili na područjima za koja postoje vizualni zapisi iz prijašnjih godina kao što su fotografije, videosnimke, slike krajolika i sl. Brojne promjene vidljive su danas duž istočne obale Jadrana npr.: otapanje leda u planinskim speleološ-kim objektima (Ledenica u Štirovači) (Boi i dr., 2012.), podizanje razine mora (Faivre i dr., 2013.; Faivre, Butorac, u tisku), poplave kao posljedica oborinskih ekstrema (Abdulaj i dr., 2014.; Gaji-Čapka, Cindri, 2014.) učestala jaruženja (Faivre i dr., 2011.), česta olujna nevremena i olujni uspori (Meugorac i dr., 2015), aktiviranje klizišta (Faivre i dr., .; Mihali i dr., 2017.) i mnoge druge.Promjene se najprije i najlakše mogu primijetiti duž obale, gdje se kopneni i marinski okoliši isprepleću. Stoga su obale danas ključna geografska područja, jer lež...
