Sažetak
This paper examines capabilities of the Structure-from-Motion (SfM) photogrammetry for monitoring of changes on pocket gravel beaches. A single digital camera was used to get images from a beach on the Croatian coast. This provided a cheap and quick image requisition. Images were processed by an online available SfM photogrammetry software. 3D point clouds derived from images were of 5 cm accuracy. Georeferencing of 3D point clouds using permanent ground control points (GCPs) enabled their comparison and assessment of beach changes. Number of parameters, which are relevant for examining beach geomorphology and which can potentially be used for coastal management are derived from the point clouds. Moreover a series of measurements taken on before and after storms can be useful for assessing stability and sustainability of these coastal systems
