Abstract: Based on the CiteSpace visualization tool, a bibliometric analysis was conducted on literature in the field of flash flood disasters from the China National Knowledge Infrastructure (CNKI) and Web of Science (WOS) core databases between 2010 and 2025. Analyzing 1,173 Chinese and 1,021 English publications, this study examines multiple dimensions including publication volume, international collaboration, core institutions, author networks, keyword co-occurrence, and keyword bursts. The research indicates significant differences in the scale of research between China and the international community. The annual publication volume in the CNKI database shows slight fluctuations, while the WOS database exhibits a continuous increase since 2017, peaking at 169 publications in 2024, highlighting the growing international attention. Institutional analysis reveals that the China Institute of Water Resources and Hydropower Research and the Engineering Technology Research Center of Flood and Drought Prevention and Mitigation, Ministry of Water Resources, among others, play dominant roles both domestically and internationally. International collaboration primarily involves domestic universities. Keyword analysis finds that domestic research focuses on disaster prevention and application technologies such as "critical rainfall" and "monitoring and early warning," while international research emphasizes model innovation and the integration of multi-source data, such as "spatial prediction," "climate change," and "machine learning." Keyword burst detection reveals a shift in domestic hotspots from "flash flood causes" to "risk assessment", and international focus on technological means like "machine learning." Current challenges include insufficient international collaboration, limited capabilities in multi-factor coupled numerical simulation, and a need for enhanced interdisciplinary cooperation. Future efforts should focus on building a global data-sharing network, deepening interdisciplinary collaboration and AI-assisted analysis, and promoting sustainable development in flash flood disaster research.
