Me- dia may contain several zones in which the permeability coefficients are supposed to be constants.

In this case the boundary integral equation con- tains unknown values on external and interzonal boundaries.

Numerical results are given for flow through zoned dam and near the well. INTRODUCTION The prediction of free surface position and water pressure distribution asso- ciated with seepage through porous media is an import ant problem in damsand mining design.

The boundary element method is perhaps the most efficient tool for solving the seepage problem [1-4] involving fr...
