To determine artificial reefs arrangement in marine forest, the relationship between ocean current and algal spore movement could be clarified at the study area. Ocean current of the study area has been dominated by wave-induced current due to wave actions, and algal spore movement would be affected by wave-induced current. To analyze wave-induced current at study area, field survey with floating buoy attached DGPS and numerical model (SWAN and EFDC) experiments carried out at the same time. The ocean current has formed a south and north direction along the coastal line and this was in well agreement with floating buoy movement. algal spore had moved in a SE-NW direction with wave-induced current and spores at the case 3 with the highest releasing point had shown the longest travel distance among the 4 experiment cases (releasing height is 4.5 m and travelling distance is 1,026.0 m). Therefore, the higher spore releasing point, the wider marine forest can be enhanced. And according to the survival time and attached range of algae spore, it was suited that the total marine forest length and distance between artificial reefs were within 800 m and 20 m (with 2 rows arrangement), respectively.
