A worldwide event-based debris-flow barrier dam dataset from 1800 to 2023

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 38 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.泥石流拦挡坝（Debris-flow barrier dams, DFBDs）不仅会改变原有的水文与地质条件，还可能引发溃决洪水、上游淤积等次生灾害。此类设施的相关数据对相关研究至关重要，但目前尚未建立针对泥石流拦挡坝的专用数据集。为填补这一研究空白，本研究采用严谨的数据采集与验证流程，检索梳理了2519篇文献及媒体报道，最终构建了包含555起泥石流拦挡坝事件的数据集。该数据集全面记录了泥石流拦挡坝的38项属性信息，涵盖地理位置、所属国家、触发因素、建成日期、可靠性、泥石流密度、泥石流流速、坝体长度、高度、宽度、体积、拦挡方式、稳定性、服役寿命、坝体材料、堰塞湖长度、容积、面积、失效机理、峰值流量及人员伤亡情况等。
