| Abstract: | A coupled numerical theory, which describes two_phase, gas and water, immiscible and incompressible seepage in unsaturated soil, has been developed. A Galerkin finite element model is used to simulate two_phase seepage under saturated and unsaturated conditions in non_deforming porous media. Examples are performed to demonstrate the model. |
