Sažetak
Coastal areas are dynamic and complex geomorphological systems often today under strong socioeconomic pressure. One of the most endangered coastal geomorphological forms are beaches. Some recent work shows that 24% of beaches are subject to erosion and 28% of beaches are prograding, while 48% are relatively stable (Luiendijk et al., 2018). Climate change, sea level rise, and increasing anthropogenic pressures make beaches highly vulnerable today. One of the most appropriate methods to calculate and assess their vulnerability is the BVI - Beach Vulnerability Index. The BVI has evolved from the CVI - coastal vulnerability index (Gornitz, 1990) and was developed by Alexandrakis and Poulos (2014). In this work, the vulnerability of beaches on the island of Hvar is assessed by combining different parameters such as beach erosion, morphometric characteristics, land cover change, wave action and anthropogenic impacts at about 40 sites. Different methods are used to analyze each parameter, including method of repeat photography, analysis of archival maps, field work (Fig. 1ab) and remote sensing method using UAV (uncrewed aerial vehicle) and satellite imagery. Remote sensing methods revealed to be very satisfactory for beach geomorphological investigations (Mićunović et al., 2021), therefore the application of remote sensing is further developed in this work. Data collected from the UAV or satellite imagery has been processed in combination with GNSS control points in Drone2Map and Agisoft photogrammetric software (Fig. 1c), and data analyses has also been performed using ESRI ArcGIS Pro software. During my PhD research, data will be collected by UAV several times a year to monitor changes in beach morphology. These results and those calculated by BVI, should contribute to further sustainable coastal management.
