| Outline of Final Research Achievements |
As an attempt to understand the dynamics of cohesive sediments in muddy tidal flats, evaluation of the properties of silt and clay related to sedimentation and self-consolidation, development of a sediment transport model considering flocculation, numerical simulations for the Imazu tidal flat were carried out. As a result, an environment for evaluating the settling velocity of suspended particle matter was established, and the characteristics related to the sedimentation and the self-consolidation of fine sediment were evaluated. Numerical experiments also revealed changes in sediment transport due to the construction of a revetment in the intertidal zone. Furthermore, numerical simulations were carried out to understand the characteristics of low-frequency oscillations that would be the driving force on sediment transport in the Imazu tidal flat.
