Analytical mapping on trends of information technology in hydrometeorological disasters research

Hydrological and meteorological disasters have a massive global influence. These disasters result in colossal property loss, deaths, and societal disruption. Information and communication technologies can help to improve the disaster management process. This study presents an analytical mapping of hydrometeorological disasters and various ITs in hazard management. It assesses the global research state of IT-based hydrometeorological disaster management in terms of citations analysis, prolific journals, organizations, and countries' contributions. Keyword co-occurrence analysis has been performed through visualization graphs to highlight research areas. VOSViewer and Bibliometrix R-package has been used for in-depth analysis and visualization requirements to identify the ICT patterns, core regions, academics, and research topics. The study highlights the emerging research areas in disaster management such as forecasting, disaster risk assessment, prediction, energy efficiency, alert generation, warning system and artificial intelligence, IoT, and cloud computing technologies have greater scope manage the disasters. This research illustrates the significance of information technology in hydrometeorological disasters and provides recommendations for future IT-assisted disaster management efforts.
