GPR-based water leak models in water distribution systems

[EN] This paper addresses the problem of leakage in water distribution systems through the use of ground penetrating radar (GPR) as a nondestructive method. Laboratory tests are performed to extract features of water leakage from the obtained GPR images. Moreover, a test in a real-world urban system under real conditions is performed. Feature extraction is performed by interpreting GPR images with the support of a pre-processing methodology based on an appropriate combination of statistical methods and multi-agent systems. The results of these tests are presented, interpreted, analyzed and discussed in this paper.This work has been supported by the project, IDAWAS (Intelligent Data Analysis in WAter Systems), DPI2009-11591, of the Direction General de Investigacion of the Ministerio de Ciencia e Innovacion of Spain, ACOMP (Accion Complementaria)/2011/188, of the Conselleria d'Educacio of the Generalitat Valenciana and the FPI (Formacion de Personal Investigador)-UPV (Universitat Politecnica de Valencia) scholarship granted to the first author by the Programa de Ayudas de Investigacion y Desarrollo (PAID) of the Universitat Politecnica de Valencia.
