Abstract
The aim of this study is to investigate a movement mechanism of organic fine particles (OFP) in a sand column, which is a useful knowledge in a restoration of aggravated tidal flat and a construction of man-mad sandy tidal flat. It was found that Hagen-Poiseuille equation could express the characteristics of flow in the sand column; and the pressure loss inside the sand column considering OFP could be formulated theoretically. The movement of OFP in the sand column estimated from the formula was verified by experiments. Moreover, the organic properties of OFP strongly affected the movement; namely, decomposed OFP were easy to travel through the sand column.
