For artificial beach constructed in coastal region facing to a coral reef, the stability of sediment is most important Meanwhile, the beach should be convenient for amenity activity and valuable to natural landscape. In order to protect the beach erosion in such artificial beaches, several countermeasures are proposed and carried out. The head land method is one of the most effective way for beach stability. This paper proposes the new effective arrangement of head lands to protect the artificial beach planed in coral reef employing the three dimensional experiments. In the experiment the level of flow which caused the beach erosion are determined in the two dimensional cannel tests.
