Abstract
In this study, applicability of one-dimensional infiltration model for NAPL pure liquid behavior in unsaturated/saturated porous media was investigated. The progressing rate of TCE front in glass beads layers, vertical distribution of TCE and water, and total amount of volatilization of TCE were used as observed values to evaluate the model. The result revealed that it is needed to introduce residual NAPL saturation in unsaturated/saturated zones to the model in order to present the observed data. The residual NAPL saturation tended to increase with water saturation in unsaturated zone. In addition, the model could present the TCE distribution when an injection rate was changed.
