Climate change and rapid urbanization, particularly in cities with inadequate infrastructure, have significantly increased the frequency and intensity of destructive floods. Beyond the devastation of physical infrastructure, floods pose grave threats to human health and the environment. Addressing these challenges necessitates the adoption of hydrological modeling and simulation to predict and manage floods effectively. This research explores the potential of metaverse technologies in flood modeling and visualization. Virtual reality (VR) and augmented reality (AR) tools offer highly precise simulations of flood scenarios, enabling planners, citizens, and stakeholders across communities to make informed, practical decisions based on complex datasets. These technologies facilitate more effective risk mitigation and damage reduction strategies. By offering more immersive and realistic simulations, metaverse technologies greatly enhance predictive accuracy and decision-making in flood crisis management. Consequently, they hold a transformative role in reducing vulnerabilities and strengthening community resilience against natural disasters.
