Floods, seepages, and animal activities are known to be the main causes of internal damage and erosion of embankments, all these factors lead to partial or complete collapse. Embankment integrity losses may progress without any superficial or easy detectable evidence, in consequence visual surveillance or localized techniques are not effective. Geophysical techniques for characterization of embankments are constantly improving. In literature, there is evidence of numerous advances on the application of electrical and electromagnetic surveys. Refraction and surface wave methods are less considered because they can be more time consuming. They usually work best to assess vertical profiles of a limited section of the subsurface, without considering lateral variations of waves travelling through the media, which may lead to erroneous characterization.
