Beach changes associated with the interaction and mergence of the cuspate forelands formed at the end of two sandy islands were predicted using the BG model under the condition that waves were incident from completely opposite directions, and each cuspate foreland was subject to the wave-sheltering effect of another island. The mechanism of beach changes associated with interaction and mergence of multiple islands was successfully explained by the numerical simulation.
