Abstract

Provedeno je istraživanje morfodinamike umjetne šljunčane plaže Ploče tijekom proljeća 2022. godine primjenom metode pametnih RFID valutica. Metodom UAV-SfM-MVS fotogrametrije, dGPS profiliranjem plaže, granulometrijskom i morfometrijskom analizom sedimenta te faznom analizom pomoću rendgenske difrakcije na prahu je dobiven sedimentološki i morfološki kontekst istraživane plaže prema kojem su rezultati metode pametnih valutica interpretirani. Srednja veličina zrna sedimenta plaže iznosi Md = 39 mm te je uočen trend pokrupnjavanja od SZ prema JI, uz iznimku područja proboja podzemnih voda gdje je uzorkovan sitni sediment s Md = 2,4 mm, sastavljen dominantno od kalcita. Kratkoročne morfološke promjene ukazuju na prevladavajući utjecaj zapljuskivanja valova u okviru plimnih uvjeta, a dugoročne ukazuju na akumulaciju sitnijeg sedimenta na SZ dijelu plaže te krupnijeg u zoni beach step-a što je uvjetovano nagibom intertajdala i sedimentnim karakteristikama okolnih valutica. Erozija je najizraženija na području proboja podzemnih voda. Pozicija berme se mijenja ovisno o dosegu valova tijekom nevremena, a pri mirnim uvjetima ovisno o morskim mijenama koje određuju doseg valova.

Abstract (english)

Morphodynamics study of the artificial pebble beach Ploče was conducted during the spring of 2022 using the “smart pebbles” RFID method. UAV-SfM-MVS photogrammetry, dGPS beach profiling, granulometric and morphometric sediment analysis, and X-ray powder diffraction mineral phase analysis provided the sedimentological and morphological context of the studied beach for the interpretation of the smart pebbles method results. Median grain size of the beach sediment is Md = 39 mm, and a coarsening trend was observed from NW to SE, with the exception of the groundwater seeping area where the finer sediment, of Md = 2.4 mm, composed predominantly of calcite, was sampled. Short-term morphological changes indicate the predominant influence of swash action during various tidal conditions. Long-term changes indicate the accumulation of mostly coarse pebbles on the NW part of the beach and cobbles on the beach step, depending on the intertidal slope steepness and the sedimentary characteristics of the surrounding pebbles. Erosion is the most prominent in the area of groundwater seeping. The positions of berms change depending on the storm wave run-up and fair-weather run-up modified by tidal conditions.
