从防灾、滨海环境和利用的综合角度，采用了各种新型海堤，取代了现有的垂直海堤和块状土丘海堤。然而，复杂形状海堤越浪率的实用估算方法尚未建立。因此，本研究的目的是通过使用二维数值波浪水槽CADMAS-SURF进行数值模拟，对冲绳主岛道路护坡周围的波浪漫顶对策进行数值模拟。结果表明，CADMAS-SURF能较好地反映实际海区的越浪现象。此外，利用CADMAS-SURF进行数值计算，对于全面讨论防止越浪灾害是有用的。
Various new types of seawalls have been adopted instead of existing seawalls such as vertical and block mound seawalls, from the comprehensive viewpoints of disaster prevention, coastal environment and utilization. However, a practical estimation procedure for wave overtopping rate of complex-shaped seawalls has not been established yet. The purpose of this study is, therefore, to numerically examine countermeasures against wave overtopping around road revetment in Okinawa Main Island by conducting numerical simulation using a two-dimensional numerical wave flume 'CADMAS-SURF'. As a result, it is revealed that the CADMAS-SURF can represent wave overtopping phenomena at actual fields. Moreover, numerical computations with the CADMAS-SURF are found to be useful in comprehensively discussing the prevention of wave overtopping disaster.
