This paper deals with the identification of a zone permitting fluid to leak out of a drain. Using the analogy with crack identification by boundary measurements, we give uniqueness and stability results and we propose an algorithm for the numerical solution of the problem. Since the forward problem consists of a mixed boundary value problem with a strong anisotropy, we discretize it by a mortar spectral element method. © 2005 Springer Science+Business Media, Inc.
