We investigated the fundamental physical and chemical properties of dredged soils (hedoro) taken from Haneda, Kasumigaura, Saga and Ohbagawa. We also investigated the changes of consistency index, pF-moisture curves and saturated hydraulic conductivity of Haneda and Kasumigaura soils at different drying stages. The results are summarized as follow ; 1. There were large variations in fundamental physical and chemical properties of dredged soils collected from different places. 2. In air - dried soils, hydraulic conductivity increased while increasing in dry density. 3. The drying caused an irreversible effect on consistency index, pF-moisture curves and saturated hydraulic conductivity. These facts indicate that the effects of drying on these properties are considered to be resulted from irreversible changes in the structural status of the soil.
