1. A method for analyzing a condition of a pipeline in real time, comprising:
generating a transient pressure wave in fluid carried along the pipeline;
detecting a transient pressure wave interaction signal responsive to the transient pressure wave, the transient pressure wave interaction signal having a time duration corresponding to a region of interest of the pipeline; and
processing the transient pressure wave interaction signal to analyze the region of interest of the pipeline, wherein processing the transient pressure wave interaction signal comprises:
downsampling in the time domain the transient pressure wave interaction signal to generate a downsampled time window of pressure information;
processing the downsampled time window of pressure information by an artificial neural network (ANN) trained to identify a hydraulic feature of a first type and determine associated hydraulic feature characteristics of the hydraulic feature of the first type; and
verifying whether the hydraulic feature of the first type occurs in the region of interest of the pipeline.
