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.
