On the Takata-matsubara coast, sandy beach was severely eroded by the return flow of the 2011 Great Earthquake Tsunami occurred on March 11, 2011. The recovery of sandy beach was planned using beach nourishment. In this study, the effect of beach nourishment using relatively coarse materials such as the grain size of 1 mm was investigated using the BG model. Because three artificial reefs with a crown depth of 3 m have been constructed before the earthquake on this coast, beach changes due to these artificial reefs were taken into account.,
