Short summary

This research presents a unique 64-year (1961–2024) debris-flow dataset for Jiangjia Ravine, Dongchuan, Yunnan, China. The dataset includes detailed measurements of debris-flow kinematic parameters (velocity, depth, and discharge), physical–mechanical properties (particle size, yield stress, and viscosity), seismic data, and hydrometeorological records (e.g., minute-by-minute rainfall and soil moisture). The dataset is publicly accessible via the National Cryosphere Desert Data Center (NCDC).
