Modeling of Resuspension Mechanism of Deposited Organic Mud in the Tidal Estuary

Abstract

The excess deposition of organic matter impacts to the eco-systems in brackish water regions. Improving the environment is necessary to understand the deposition and transportation characteristics of organic matter. In this study, salinity effect to resuspension characteristics of organic mud was examined. From these results, a resuspension model which can consider the qualities of organic mud and water salinity was estimated. It was clarified that the calculated resuspension flux and grain size distribution using this model extremely replicate the measured data. Additionally, this model can grasp the particle size selection by salinity.
