Leak identification in porous media by solving the Cauchy problem
[Identification de fuites dans un milieu poreux par résolution du problème de Cauchy]
Comptes Rendus. Mécanique, Volume 335 (2007) no. 7, pp. 401-406.

Nous proposons dans ce travail, l'identification de fuites dans un domaine poreux homogène et saturé, en résolvant un problème de Cauchy. Cette résolution est effectuée au moyen d'une procédure de minimisation d'une fonctionnelle d'erreur énergétique développée en 2006 par Andrieux et Baranger.

We propose in this Note a method of identifying leak zones in a saturated and homogeneous porous domain by solving a Cauchy problem. The method is based on the minimisation of an energy-like error functional procedure developed in 2006 by Andrieux and Baranger.
