This Paper derives the differential equation to compute the seepage field based on the Darcy Law and continuity equation, then discrete the differential equation in finite difference method, establish a calculation matrix by changing it into algebraic equation, combined with the boundary condition, the seepage field can be computed. Besides, the seepage of a fill dam with homogeneous material is computed in this modeling, by dividing the grids, considering the boundary condition, the seepage water head is solved and witch can reflect the real engineering. It shows the mo...
