| Outline of Final Research Achievements |
In this study we have the following numerical results, which is concerned with the realization of the behaviour of the non-stationary seepage governed by non-linear diffusion and evaporation.
(1) Imposing the constant value on the boundary condition, we observed that the numerical support which is a simple connected domain changes into a non-connected domain as the time increases. This means the appearance of the zeros of the solution of the model equation. (2) Imposing the sufficiently long period on it, we obtained the phenomena of the repeated appearance and disappearance of the zeros. (3) On the other hand, imposing the sufficiently short period on it, we didn't observe the appearance of the zeros.
We proved the phenomena stated above from the mathematical point of views.
