%X Debris-flow barrier dams (DFBDs) not only reshape the original hydrological and geological conditions but may also trigger secondary disasters such as outburst floods and upstream aggradation. Data on DFBDs is crucial for related research. However, there is no dataset for DFBDs has been established. To fill this gap, we adopted a rigorous data collection and validation process, reviewed 2519 literatures and media reports, and constructed a dataset of 555 DFBD events. The dataset comprehensively records 36 attributes of the DFBDs, including location, country, trigger, the date of formation, reliability, debris flow density, debris flow velocity, dam length, height, width, volume, blocking mode, stability, longevity, dam material, lake length, lake volume, lake area, failure mechanism, peak discharge, and loss of life, etc.
