AbstractQuantitative descriptions of the two-phase flow in the subsurface soil require knowledge of the relative permeability-saturation-capillary pressure Kr-S-Pc relationships. The significance of the present study lies in introducing a physical model that was used to measure the capillary pressure-saturation curve for the twophase kerosene-water system in Kerbala�s sand. The experimental results are fitted with the empirical mathematical function described by (Parker et al., 1987) which is based on (Van Genuchten�s model, 1980). This function can be used to specify the residual water saturation, Sr, and Van Genuchten�s soil parameters, α and n. The best-fit curve was found by using a nonlinear least squares fitting routine using the SPSS software version 7.5. The fitting parameters Sr, α and n for the best-fit to Van Genuchten�s capillary pressuresaturation curve for kerosene-water system have the values of 7%, 0.048 cm-1 and 2.7, respectively, for Kerbala�s sand.
