Abstract
National land of Tuvalu was formed by coral gravel and sand. Although the island is vulnerable to high wave and beach erosion due to a narrow and low elevated land, proper coastal conservation measures had not been implemented because of the difficulties of procurement of materials and equipments. Gravel beach nourishment was proposed as a coastal conservation measure to improve three functions; protection, beach use, and environment using sustainable materials in Tuvalu. Gravel beach and groins were designed with consideration of these three functions as well as the reduction of required volume of materials. Environmental education was conducted to the public to improve their awareness on beach environment, and to enhance their voluntary participation to beach management and a certain effect by the education was confirmed through interview survey to stakeholders.
