Abstract
Funamanu Island is a coral cay with 0.8 km length located in Funafuti Atoll in Tuvalu, and is located 0.6 km west of Fongafale Island with the capitol of Tuvalu. On this island, a large amount of gravel was transported from the offshore zone during Tropical Cyclone Bebe that hit the island in October, 1972. The changes in configuration of the island and the deposition of gravel were investigated using aerial photographs in July 1971 before the cyclone and in August 1984 after the cyclone as well as the satellite image in June 2010. Field observation was also carried out to investigate beach condition of this island and measure the topography of the coral cay.
