| Scope | Recent developments of field observation, physical and numerical experiments, and mathematical analysis have brought us a better understanding of the dynamics of turbidity currents and relevant morphology and bedforms. Applying new findings to rock records, more profound understanding of turbidites have been achieved. It has been found that different triggers and/or sources generate distinctive features of turbidity currents, resulting in various appearances of rock records and morphology. The integration of such new knowledge on turbidity currents is important not only from scientific but also practical points of view, such as assessments of natural hazards, and exploration of resources. This international session welcomes all kinds of approaches for the turbidity currents such as field observation, physical and numerical experiments, mathematical analysis, and studies from rock records. | |
