NUMERICAL STUDY ON ACCUMULATION MECHANISM OF CORAL GRAVELS AROUND BALLAST ISLAND, THE CORAL CAY OFF THE COAST OF IRIOMOTE ISLAND. (2018). Coastal Engineering Proceedings, 1(36), sediment.93. https://doi.org/10.9753/icce.v36.sediment.93

Resumen

Understanding the formation mechanisms of a coral cay or a coral beach is essentially important to consider better conservation and protection strategies and measures of coral coast. Ballast island is a coral cay formed on the isolated reef located off the coast of Iriomote island, Okinawa, Japan. While this small coral cay frequently alters its shape under the attacks of severe waves, coral gravels gather around the island and keep the island around the same location. This study carries out the field survey and the numerical study to investigate the physical mechanisms of above mentioned characteristic behavior of coral gravels.
