In this work, we have monitored some debris flows in an artificial inclined flume, instrumented with approx. 800 m of fiber, wound in 20 coils. The fiber was interrogated using a distributed acoustic sensing (DAS) system based on a chirped-pulses phase-sensitive optical time-domain reflectometer and the acquired signals were analyzed confirming the viability of DAS for debris flows monitoring.

Abstract
In this work, we have monitored some debris flows in an artificial inclined flume, instrumented with approx. 800 m of fiber, wound in 20 coils. The fiber was interrogated using a distributed acoustic sensing (DAS) system based on a chirped-pulses phase-sensitive optical time-domain reflectometer and the acquired signals were analyzed confirming the viability of DAS for debris flows monitoring.
