In this study, applicability of one-dimensional infiltration model for behavior of four Non-aqueous phase liquids (NAPLs) in unsaturated/saturated porous media was investigated by comparing of calculated values with observed values. The progressing rate of NAPL front in glass beads layers, vertical distribution of NAPL and water after NAPL movement stopped, and total amount of volatilization of NAPL during experimental period were used as observed values. It is found that this model can present behavior of NAPLs, whose densities are larger than water and spread coefficients are positive, but that the model tended to overestimate downward migration of LNAPL such as Toluene. Moreover, this model cannot be applied to NAPL such as Bromoform, whose spread coefficient is negative.
