In many ports, long-period waves decrease the efficiency of cargo handling and sometimes cause break of mooring ropes. One of the most effective ways to reduce the long-period waves in a port is to construct the wave absorption facilities. Then, we proposed a new-type long wave absorption structure with two oblique walls. The length of the structure is shorter than the other long-wave absorber. The basic performance of the facility has already been examined by the hydraulic experiments.
In this paper, we propose the structural type (gravity type, sheet pile type, etc.) of long-wave absorber with oblique walls and the wave-absorbing performances for them are experimentally investigated.
