Abstract
An array of acoustic sensors spaced along a cable is deployed in a fluid filled concrete pipeline and the sensors are monitored to find acoustic anomalies, particularly anomalies resulting from breakage of a reinforcing wire for the concrete. The location of wire breaks is found from the data collected.
