Predicting behaviors of fine sediments is an important issue in terms of keeping navigation channels, an aquatic conservation and so on. So numerical models on sediment transport have been improved to achieve a high accuracy prediction. On the other hand, it is laboring to determine parameters for numerical models taking complicate behaviors of sediments into account. In the present study, a series of experiments was carried out to understand characteristics of a mud deposit. As the result of this study, it was possible that parameters associated with settling, self-weight consolidation and erodibility were determined by simple experiments with a settling column. In addition, the result of experiments by Gust Erosion Microcosm implies that a state of consolidation has no small effect on erodibility of mud deposits.
