Time-lapse Seismic Measurements on a Small Earthen Embankment during an Internal Erosion Experiment

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