Abstract: A solution procedure using the Green's function based finite element method (FEM) is presented for two-dimensional nonlinear steadystate seepage analysis with the presence of free surface in isotropic dams. In the present algorithm, an iteration strategy is designed to convert the over-specified free surface problem to a regular partial differential equation problem. Then, at each iteration step, the Green's function for isotropic linear seepage partial differential equation is employed to construct the elemen… Show more

“…Because of the complexity of analytical solution of seepage flow governing equations, numerical methods are usually pursued to deal with problems. The finite element method (FEM) has been widely accepted due to its capability to get along with the inhomogeneous and anisotropy materials and complicated boundaries [3][4][5].…”
