On this paper, inverse analysis calculation by the boundary element method is studied. Case studies are made to show that this technique is useful for inverse analysis of confined heterogeneous porous media. A technique by the three-dimensional boundary element method is proposed for inverse analysis for the determination of the optimum location of three-dimensional drainage facilities. The coordinates of the construction site for the three-dimensional drainage facilities are set up as search values and Gauss-Newton method is applied to continue the process of minimization of the objective function that is calculated by the least square method untill the pressure head at the bottom boundary region becomes to the required value. This technique is usefull for the determination of construction location for three-dimensional drainage facilities, which are necessary to determine the required safety factor of the slope.
