the seepage characters of the earth dam should be analyzed in the hydraulic engineering and the free surface should be determined firstly. According to Darcy’s law
seepage constitutive equations
water head and flux boundary condition
a model is established for the seepage in the in homogeneous earth dam on imperviousness groundwork. By the Geoslope software
the free surface of the earth dam is calculated using the finite element method
and the change of the free surface is analyzed when the permeability of the earth dam is changing. At last
the numerical simulation of the free surface is verified by an analytical solution.
