Number of coastal protection structures have been increased rapidly due to rising sea levels and deteriorated sea conditions. Coastal structures should be designed to meet coastal engineering requirements and ecosystem conditions, while they are not lost or removed. In this study, trapezoidal gabion block was developed for the purpose, and two-dimensional laboratory experiments were conducted to validate applicability of the block. The experiments were carried out with eight types of erosive and accretive wave conditions. As a result, it was confirmed that the gabion blocks have a feature of preventing erosion of beach. The newly designed gabion blocks could be an alternative as a countermeasure method for beach erosion.
