In most geotechnical analyses, soil properties are assumed to be spatially and temporally invariant; however, these soil parameters usually vary from point to point and also may vary in time. Therefore in this research, the coefficients of permeability are assumed to vary in terms of geometry, external load influences and the effect of head variation in the system and the resulted nonlinear seepage problem is solved using Finite Difference Method. The seepage Problem is analyzed for two cases of variable and constant coefficients of permeability. The results are also compared with the Least Square FE Method.
