Abstract

Summary

The aim of this study was to assess the capabilities of seismic Ambient Noise Interferometry (ANI) with fibre-optic Distributed Acoustic Sensing (DAS) data to monitor earthen dams. A test dam was used to assess the applicability of ANI methodology to small-scale infrastructure with imaging and monitoring of the dam using DAS data. The study highlights anomalous regions in the Älvkarleby Test Dam that may be defects. Problem areas highlighted in this way can be further assessed to determine the need for remediation work. The study demonstrates the potential to combine DAS and ANI techniques to image and monitor infrastructure and landslides at distance from a fibre-optic cable.
