Solution of Confined Seepage Problems below Hydraulic Structures by Finite Element Method
Confined seepage problems below hydraulic structures using finite element method are investigated. The foundations are assumed to be infinite with homogeneous and isotropic conditions. Three different types of elements with varying mesh sizes are used for comparing the finite element results with those of exact solutions for simple boundary configurations. Iso-parametric quadrilateral elements which are best suited for inclined boundaries are used for solving the seepage problem beneath practical profiles of complicated boundary forms. The numerical results.
