Abstract Although the scientific investigation into flood hazard assessment (FHA) has increased in recent years, a global analysis of FHA-related studies is still rare. This research aims to elucidate trends in FHA-related scientific inquiry from a quantitative perspective. A bibliometric analysis was conducted to analyze a sample of 723 articles published in the period 2000–2020 from the Web of Science databases (WoS). Bibliometrix R-Tool was used to explore the trends and themes in this field by analyzing substantial documents, sources, and authors. Results show a growing number of scientific publications during the past two decades and a poor collaboration network between countries in this field. Keyword analysis shows that the themes of this research domain were focused on modeling. The main finding is that FHA remains an under-investigation field of study that focuses on specific geographical areas. Nevertheless, international collaborations present an increasing trend in FHA-related research, and a growing number of scholars have significant interests in FHA, whose topics are gradually systematized. These findings offer a comprehensive picture of FHA-related research and suggest the need for and benefits of collaboration across geographical study areas.
