In this study, a high-frequency video monitoring systems was employed to automatically extract tens of thousands of shoreline positions for five urban beaches in Barcelona city during the 2001-2022 period. The Barcelona coastal video monitoring system has been operational since November 2001, initially as an ARGUS Station (Holman and Stanley, 2007) and later utilizing the open sources software SIRENA (Nieto et al., 2010) and ULISES (Simarro et al., 2017). This extensive dataset is processed to generate daily average shorelines, which are then used to calculate the daily emerged area of each beach.
