Abstract

The purpose of this study was to investigate the stability of the arched and fan types of artificial reefs, which provide habitats for shellfish and seaweed. According to the Froude similitude, parameters affecting the stability of the artificial reefs were analytically, experimentally studied. First, the design parameters of the artificial reefs in wave and current fields were presented. Then, using dimensionless parameters, such as the surf similarity parameter and water particle speed, the stability of the arched and fan types of artificial reefs was investigated. From the hydraulic experiments, it is shown that the stability heavily depends on the way the artificial reefs are installed. Therefore, the installation of the artificial reefs on the surf zone should be carefully executed.
