• Initial understanding and assessment of role of oceanographic features for ferromanganese crusts and nodules in the East Vietnam SeaInitial understanding and assessment of role of oceanographic features for ferromanganese crusts and nodules in the East Vietnam Sea

    Abstract The iron and manganese content in marine water is very small but the volume of ferromanganese nodules contributes 30% of the total mass of polymetallic nodules and crusts in marine and ocean floor. This suggests that the process of enrichment of ferromanganese crusts and nodules is not only contributed by chemical processes but also by...

    INTRODUCTION Most of the structures built on the coral foundation are frames that consist of 3D beam elements. Under the wave and wind loading, response of the structure is periodical. However, in the case of strong waves and wind or ships approaching, the structural system is usually subjected to impact load. The simultaneous impact of hor...

    Abstract Seawalls have been erected to protect hundreds of towns and tourism areas stretching along the coast of Vietnam. During storm surges or high tides, wave overtopping and splash-up would often threaten the safety of infrastructures, traffic and residents on the narrow land behind. Therefore, this study investigates these wave-wall intera...
