Abstract
In this paper, we propose a two-phase mixture model which represents the moisture movement through porous media, in which moisture is assumed to exist in two phases, namely trapping and free phase. We obtain an analytical solution of a linearly approximated model derived from the two-phase mixture model. We then apply the solution to the experimental results of unsaturated vertical flow for snow samples.
As a result, we find that the solution agree very well with a process of run-off from snow samples in experiments. Moreover, we examine the characteristic of model parameters based on the computational results.
