Résumé

We propose a method for the identification of leakages in dikes using the temperature data obtained through fiber optic distributed temperature sensors. We showed how it is possible to treat leakage identification as a source separation problem. The sources were considered as defining the response of the ground, the known structures in the path of the fiber sensors (drains), the seasonal variations, the precipitations and, of course, the leakages, the last ones being our desired signals. We showed that with the help of techniques based on data decomposition and source separation (by PCA and ICA techniques), we can identify the leakages.
