The paper describes a numerical method for the analysis of seepage problems which has a major advantage over alternative methods such as the finite difference method, FDM, or finite element method, FEM, because only the data describing the boundary geometry and boundary conditions are required as input. The solution throughout the domain is continuous and defined by the boundary values and the numerical values of the solution parameters at any point can be calculated directly from the boundary values. Because of these features, results can be output in a format suited to the user's needs or alternatively, all the necessary information to describe the solution can be transferred from one program to another in a small data file containing a description of the boundary geometry and the boundary solution values. Experience with the method indicates that it can handle the range of problems normally encountered in civil engineering applications.
