This session focuses on the integrative understanding of the dynamics of various geophysical particulate gravity currents, including (but not limited to) turbidity currents, debris flows, pyroclastic density currents, snow avalanches, flood flows, river flows, tsunami inundations, and landslides. Although each of these currents is a different phenomenon, they share a certain degree of similarities in their dynamics. In recent years, models of the currents suitable for practical applications have been proposed in the individual scientific fields. The discussion beyond the boundaries of scientific fields allows us to integrate the knowledge of each phenomenon and deepen our understanding of the similarities and differences among various geophysical gravity currents. This integrative understanding is essential not only for scientific progress but also for practical applications such as risk assessment of natural disasters. We welcome contributions related to various geophysical gravity currents from all kinds of approaches, including physical experiments, numerical simulations, mathematical analyses, and field observations.
