Abstract

Because of the increase in coastal erosion problems, many studies have been conducted to prevent coastline retreat by developing low-cost, highly effective countermeasures. We developed the artificial coral reefs (ACRs) method as part of this research trend. To verify its coastal protection performance, we carried out performance tests on its wave attenuation and beach sand capture ability, which are the key barometers for this newly developed technology. In this study, three different types of methods, including natural beach, TTP, and ACRs, were used to determine the coastal protection efficiency under both ordinary and storm wave conditions. Based on the results of this study, ACRs were found to have the best wave attenuation performance and captured more than 20% of the total erosion area. This means the ACR method can be applied as a reliable countermeasure to protect a coastal zone.
