Improved detection and characterization of anomalies in a continuum of water

The present invention relates to a device for detecting and characterizing anomalies in a continuum of water. The device is configured to receive measurements of physical quantities from sensors situated in the continuum of water. The measurements are thereafter transformed, and anomalies are detected by an anomaly detector which is trained with transformed values obtained from the above sensors. In parallel with the detection, predefined rules make it possible to characterize a possible anomaly. Thus, an anomaly detection can be optimized for one continuum of water in particular, whilst the characterization with predefined rules allows the device to be operational without each anomaly having had to be detected in this particular continuum of water.
