Abstract
From past studies, it was clarified that the movement of pore water in the sea bed is the main cause of high turbidity layer generating over the sea bed, and the pore water keeping ability of the setting mud is depend on the organic matter adhering to the soil particles.It is thought that the organic matter makes the pore space increasing and the expansions of the mud layer.In this study, the organic mud property (IL, D50, C/N) with the pore water moving is discussed by analyzing the observation data, and the relationship between the organic matter content and the sediment expansion mechanism is cleared by the pore water infiltration experiment.
