An approximate finite element method is presented for the transient unconfined flow of porous media combined with un-saturated zone. Free surface water line is progressed by the changing procedure of element situation according to the condition of flux values. This leads to an approximate but simple calculation scheme because of no-remesh element in spite of un-homogeneous media condition. The solution is compared with other solution. It shows the technique is capable of the giving meaningful results when the slope stability analysis carries out on the submerged landslide slope.
