Abstract

In order to improve the stability of breakwater due to tsunami-induced overflow and seepage flow, it is effective that putting armor blocks on the harbor-side mound of breakwater. A hydraulic model experiment for the model of Kamaishi Bay breakwaters under tsunami condition was conducted to evaluate the extent of armor block damage focusing on the weight, the height ratio (the ratio of the armor block height to the armor block diameter) and the open ratio of the armor block (the ratio of the open volume to the armor block volume).
