Coastal Erosion and Management of Majuro Atoll, Marshall Islands

Chunting Xue

Abstract


About fifty kilometers of lagoon coast in Majuro Atoll is suffering erosion, which is induced by human activities including aggregate excavating and building causeways, artificial channels, landfill and other constructions. The west longshore sediment transportation on lagoon coast is significant for stability of lagoon shore of the west atoll. The lagoon coast erosion on the west atoll is induced by development on the east atoll. Distribution of beachrock demonstrates former existence of a continuous land on the south rim. The causeway has not caused sea level rising in lagoon. Openings on the south rim should not be made, as these will induce severe erosion. Reforming lagoon coastal constructions is proposed.

Keywords
