Abstract

 In this research the one dimensional two-phase flow equqtion for the simultaneous flow of air and water from a vertical soil column presented here based on the aljebraic sum of the water and air velocities (the total velocity) which have been derived elsewhere .In evaluating some of hydraulic parameters, the Brooks - Corey functions (Brooks and Corey 1964) are used. For the relative permeability and effective saturated to wetting and no wetting phases are used to calculated the parameters in this equation.To obtain hydraulic parameters in the Brooks and Corey equation, experimental investigation presented and hydraulic conductivity is measured and the same column homogeneous soil is dryed.The experimental data is companied with the predicted values by this equation, which was showed a good agreement.On the other hand the values of D* and a are culculated by the Brooks - Corey functions and the results of the changes of these parameters over the conclusions were evaluated and it shoued that the D* changes had a significant or meaningful effect on the computations but the changes of a had not a considerable effect on the computations so, we can consider its quantity as (1) because its practical objects. Concerning to the complicated connection of quantities the volume of computations is reduced considerably.
