Abstract
The failure of earthen embankments is associated with erosion, overtopping, seepage, piping,<br>slope failures, and slides. Precursory evidence for certain failures can be identified by visual inspection;<br>however, others are not so easily detected. Seismic imaging and monitoring may provide unique and<br>valuable precursory information about the onset of piping, seepage, and anomalous pore pressures to<br>assist in the evaluation of the integrity of an earthen embankment.
