Abstract
Prirodne i umjetne plaže na Hrvatskoj obali izložene su brojnim pritiscima, povećan broj turista i vremenske prilike sve više dovode do poremećaja njihove stabilnosti. Plaža Dugi Rat jedna je od mnogih takvih plaža, umjetno izgrađena, zbog neprestane erozije i gubitka sedimenta, zahtjeva prihranjivanje na godišnjoj bazi. Analizom zrna i usporedbom sa okolnim sedimentima na plaži utvrđeno je kako se radi o neprikladnom materijalu. U travnju 2018. godine promijenjena je praksa nasipavanja plaže. Korišten je krupniji materijal, čime se problem konstantne erozije trebao ublažiti. Radi određivanja morfoloških promjena i promjena volumena materijala na plaži izrađeni su digitalni elevacijski modeli (DEM-ovi) uz pomoć metode SfM fotogrametrije. Rezultati koji su izvedeni iz 3D modela ukazali su kako je gubitak sedimenta i dalje prisutan uslijed dužobalnog transporta, a prividna akumulacija je rezultat nasipavanja i zapunjavanja erodiranih područja. Ipak korištena metoda se pokazala kao vrlo efikasna i brza, a sami rezultati naglasili su potrebu za daljnjim promatranjem i praćenjem plaže u Dugom Ratu, kao i mnogih drugih plaža diljem istočne jadranske obale.
Abstract (english)
Natural and artificial beaches on the Croatian coast are exposed to numerous pressures, increased number of tourists and weather conditions are increasingly leading to their stability disturbance. Dugi Rat beach is one of many such beaches, artificially built, because of continuous erosion and sediment loss, requires nourishment on an annual basis. Grain analysis and adjecent beaches sediment comparision showed that used material was not suitable. In April 2018. beach replenishment practice was changed. Material with larger grain size was used which should have eased the problem of constant erosion. In order to detect morfological and volume changes on the beach, using SfM photogrammetry method, digital elevation models (DEMs) were made. Results derived from the 3D models showed that material loss is still present due to longshore sediment transport, and that apparent accumulation is a result of beach replenishment and eroded spots filling. Nevertheless, used method proved to be very effective and quick, and obtained results had highlighted the need for further observations and monitoring of Dugi Rat beach, as well as other numerous beaches along eastern Adriatic coast.
