<p>Dynamic analysis of earthen embankments is a crucial aspect in geotechnical engineering. It has been difficult to properly analyze the embankments, as it is difficult to obtain any experimental or field data. Centrifuge experiments on embankments would help us to properly understand the behavior of embankment, if we could simulate the conditions in centrifuge as close as to field. This study aims to experimentally simulate the response of an earthen embankment which is usually used for agricultural purposes, in centrifuge. Water level in the embankment is controlled and drawdown of the water was induced using a custom developed in-flight control of water path during centrifugal rotation. LVDT is used to measure the surface settlements. We have simulated the phenomenon which make the embankment weak in strength, steady state and rapid drawdown, and give shaking to the model to observe how theses phenomenon would affect the strength of embankment. Time histories of acceleration and pore water pressure are shown in this paper. Even though both steady state and rapid drawdown are critical phenomenon of embankment, cracks and failure of upstream slope is seen only in rapid drawdown condition.</p>
