抄録

Infiltration characteristics in inorganic particles of a sand and a glass beads, and organic particles of a leaf mold, a peat and a polyethylene, are clarified by capillary rise experiments. The capillary rise of pure water became higher in the order of glass beads>sand>leaf mold>peat>polyethylene, which corresponded to the smaller order of contact angle between water and the solid particle. That corresponded to hydrophile property. The capillary rise of a high concentrate anionic surfactant solution was similar among those particles, except the leaf mold, because there was not large difference of contact angles. The anionic surfactant changed the surface of the organic particles to be hydrophilic. The saturated hydraulic conductivity of the leaf mold decreased significantly when the surfactant solution was percolated. The decrease was due to the swelling of the leaf mold that adsorbed the anionic surfactant. The capillary rise velocity was well evaluated by the coefficient included the hydraulic conductivity and the suction of the wetting front.
