    In this paper the unsteady process of constant pressure steam injection into an unsaturated porous medium (e.g. contaminated soil) is studied. Darcy's law, an overall mass balance and an energy balance at the steam front are applied to determine the position of the front. The solution, in closed form, reveals that the front position is proportional to ...t. Furthermore, an asymptotic analysis provides an approximate expression for the front position. This result quantifies the case of negligible conductive heat transfer.
