A quantitative analysis of research trends in flood hazard assessment

Studies focusing on flood hazard assessment (FHA) reviews are still rare and usually approach mapping, uncertainty, spatial scale, economic loss. Nevertheless, most of these studies only provide a snapshot the current development FHA, showing partial view, limited number selected approaches methods. This study aims to analyze historical emerging fields FHA-related research applies bibliometric analysis method based Bibliometrix tool Web Science (WoS) database. We refined 4135 articles retrieved, established dataset containing 723 articles, downloaded information all including journal, author, country, keywords, abstracts.
