Data sets

A 30 m annual cropland dataset of China from 1986 to 2021 (Version v0) Ying Tu et al. https://doi.org/10.5281/zenodo.7936885

River discharge and related historical data from the Global Flood Awareness System Joint Research Center, Copernicus Emergency Management Service https://doi.org/10.24381/cds.a4fdd6b9

Short summary

China has suffered substantial economic losses and numerous fatalities due to flood disasters. This study collected historical flood data and investigated flood-causing precipitation events and their triggered flood disasters from a 3D perspective by using the connected component 3D method. Furthermore, this study revealed the complex relationships between flood disasters and key influencing factors. The findings offer new insights into the characteristics of flood disasters.
