| Outline of Final Research Achievements |
In this study, experiments on settling and self-weight consolidation and 2D numerical simulation focused on the effect of a coastal structure on cohesive sediment transports are carried out to figure out a behavior of cohesive sediments in a coastal zone.
As a result of a series of experiments, basic and regional characteristics of settling and self-weight consolidation of fine sediments supplied into major inner bays located to the west coast of Kyushu island are clarified. And it is implied that significant decrease in settling velocity of flocs at pycnocline is possible, which cannot be explained only by a buoyant force acting on primary particles composing flocs.
