  • Description: In the construction of the new Yesa dam, a loose material dam with a concrete screen, a fiber optic cable has been installed that will allow the detection of structural anomalies during the construction and operation phase. The solution consists of a fiber optic monitoring cable embedded in the concrete of the screen that allows measuring up to 100,000 points of deformation and temperature evenly distributed throughout the structure.
    The equipment that performs the measurements operates continuously and in unattended mode, being able to generate service events in case of exceeding certain deformation thresholds. This system is a pioneering action in Spain that notably improves the knowledge of their behavior, contributing to the control of their security.
