Abstract

In Korea, the quantitative growth rate of artificial reef construction is supposed to reach the peak point. Therefore, new approach is needed to the point of artificial reefs business. Functional reefs, such as shellfish reefs, recreational reefs, seaweed reefs, and fish reefs, are beneficial alternatives. This study conducted hydraulic testing to assess the stability of corrugated artificial reefs (ARs) that were constructed to promote the growth of shellfish and seaweed. The results of this study showed that some dimensionless design parameters affected the stability of corrugated artificial reefs under a range of wave and water depth conditions in a fixed bed condition. The findings also highlight the importance of hydraulic experiments in solving the problems that have emerged in the design and construction of artificial reefs.

우리나라 연안생태계는 백화현상(갯녹음)에 의한 해조류의 감소와 어패류 등 어업자원의 감소로 인해 연안역의 황폐화에 직면해 있다. 새로운 유형의 인공어초에 대한 안정성을 평가하기 위해 본 연구에서는 2차원 단면수조를 이용하여 새롭게 개발된 인공어초의 설치수심에 따른 재현파고, 주기, 흐름 등 외력을 변화시켜 요철형 어초의 안정 조건이 되는 한계치를 구하고, 설계외력(파랑, 흐름 등)의 안정성에 대한 검토를 수행하였다. 본 연구 결과는 새로운 인공어초의 설계 및 실해역에 시공하기 위해 구조물의 안정성을 사전에 검토할 수 있는 있는 기초자료를 제공할 수 있을 것으로 판단된다.
