The International Conference on Asian and Pacific Coasts (APAC) is an international conference dedicated to promoting academic and technical exchange on coastal-related studies among countries and regions in Asia and the Pacific. APAC is jointly supported by the Chinese Ocean Engineering Society (COES), the Coastal Engineering Committee of the Japan Society of Civil Engineers (JSCE), and the Korean Society of Coastal and Ocean Engineers (KSCOE), with active participation and support from a wide range of organizations across the Asian and Pacific regions. The conference is held biennially.
