This session focuses on the integrative understanding of the dynamics of various geophy
sical particulate gravity currents, including (but not limited to) turbidity currents, debris f
lows, snow avalanches, pyroclastic density currents, lava flows, volcanic umbrella clouds,
flood flows, river flows, tsunami inundations, and landslides. Although each of these curr
ents is a different phenomenon, they share a certain degree of similarities in their dyna
mics. In recent years, models of the currents suitable for practical applications have bee
n proposed in individual scientific fields. The discussion beyond the boundaries of scientific fields allows us to integrate the knowledge of each phenomenon and deepen our under
standing of the similarities and differences among various geophysical gravity currents. T
his integrative understanding is essential not only for scientific progress but also for prac
tical applications such as risk assessment of natural disasters. We welcome contributions
related to various geophysical gravity currents from all kinds of approaches, including nu
merical simulations, mathematical analyses, physical experiments, and field observation
