Locating the Free Surface Flow in Porous Media Using the Scaled Boundary Finite-Element Method

Mohammad Hossein Bazyar and Abbas Talebi
Abstract—In water flow in porous media such as earth dams, the location of free surface as a boundary between saturated and partially saturated zones is of a great importance. The well-developed finite-element and finite-difference methods are the most popular techniques to locate the free surface of water. Each of which is of merits and drawbacks. In this paper, a new numerical scheme so called the scaled boundary finite-element method (SBFEM) is employed. This technique combines the advantages of both finite-element method (FEM) and boundary element method. Only the boundary is discretized, anisotropic materials and non-homogenous materials satisfying similarity can be modeled without additional computational efforts. Two examples are addressed and the results are compared with the results obtained from the FEM. High accuracy and versatility of the SBFEM is demonstrated. The procedure can be directly applied to other engineering problems with moving boundaries such as ice melting.

Index Terms—Free surface, seepage, scaled boundary finite-element method, unconfined flow.
