Signal Processing based leakage detection methods using passive fibre optic thermometry
Résumé
The development of early warning systems for the surveillance of earthen dikes confining the river flow is indispensable. Significant flow of water through the dike due to internal erosion is an important cause of breach and results in a thermal anomaly. The measurement of temperature is therefore capable of revealing information linked to leakage. Distributed temperature sensors (DTS) based on optical fibers present en economically viable solution for recording this temperature.
