Different from the fringing reef along the coastal beach, the reef face of the deep-sea platform reef is very steep and the water depth varies rapidly from a few thousand meters at the reef toe to a few meters at the reef edge. The special geomorphology of the deep-sea platform reef makes its hydrodynamics much different from that of the fringing reef with a gentle reef-face. Besides, the wave-generated flow induced by wave breaking has a great influence on sediment movement, nutrient transport and habitats for ma…
