The Effect to the Flow around the Artificial Reef in the Different Arrangement in Situ

Abstract

There are two methods for creating fishing ground using artificial reefs. One is a pell-mell deployment and the other is an arranged deployment. The design of arranged deployment requires characteristics of fish interested in artificial reefs and the scale of artificial reef. However, it is still not clear for design method to arrange artificial reefs. Thus this study was carried out to develop the design method to optimally arrange reefs in terms of fluid dynamics. Consequently, in situ observation represented that the difference in artificial reefs arrangement affected the flow situations around artificial reefs.
