Numerical investigations of two practical free surface seepage problems using a complementarity system formulation J.C. Bruch, Jr. Department of Mechanical and Environmental Engineering, University of California, Santa Barbara, CA 93106 USA ABSTRACT Two problems of free surface flow through a porous medium are investigated numerically. Both problems are of practical significance. One concerns the free surface seepage through an earth dam on an impervious base with a toe drain and a cutoff wall. The other problem involves the subsurface flow to a partially penetrating ditch with applications to land reclamation problems or interceptor systems to be used as a means of pollution control. Both of these free surface problems are solved by means of a fixed domain method resulting in a complementarity system formulation. Numerical results are presented for a set of representative parameters for each problem. A successive over-relaxation scheme with projection was used to obtain th
