Sistema de sensores de temperatura distribuidos. Pruebas de campo en presas de material suelto

Abstract

The present paper examines the use of optical fiber as a

distributed temperature sensor to detect leaks in earth dams.

This real-time data acquisition technique complements current

auscultation systems and improves monitoring of these

critical infrastructures. The aim of this paper is to provide a

practical illustration of this novel and promising technique and,

particularly, of the precautions to consider to correctly deploy

the sensor elements. For this last purpose, this document

describes the field tests recently carried out on the Soto

Terroba and Yesa dams and proposes best practices concerning

the implementation of the system.
