Coastline erosion, including cliffs, presents a significant challenge for coastal communities worldwide. This study focuses on investigating the rate of cliff erosion on Vrgada Island, using digital photogrammetry and the Agisoft Photoscan and Surfer software to create digital elevation models and digital surface models of difference. The analysis of height and volume differences in cliff materials allowed for monitoring changes during the winter and summer seasons of 2022/2023. The research results indicate continuous cliff erosion, which significantly intensified during periods of heavy rainfall and strong winds. Among the main factors contributing to slope processes on the cliffs of Vrgada Island are the steep cliff gradient and the influence of water, leading to material collapsing and shedding. The major material collapsing in April 2023 caused significant topographical changes in the cliff, with an emphasis on material accumulation at the base of the cliff and a reduction in the slope at the top. Looking toward the future, the increasingly warmer and stormy climates, rising sea levels, and heightened human activities will inevitably impact the coastal environment of Vrgada Island. This changing coastal landscape is directly linked to risks for the safety of bathers who frequently visit the area beneath the cliff. As erosion continues to be present, there is a growing threat of rockfalls and collapses that could jeopardize the safety of people on the beach.
