High mound composite seawalls are a new type of structure with a high rubble mound and a slit-type upright section as shown in Figure 1. The structure consist of a slit wall installed on a rubble mound that is higher than that of a normal composite structure. The higher rubble mound is designed to induce the breaking of the largest waves, thereby damping the wave energy. Wide rubble mounds are also suitable for seaweed bed development, and the formation of seaweed forests has been observed in the field surveys. This structure was developed through joint research project by Port and Airport Research Institute/Japan, LWI of Technical University of Braunschweig/Germany and Civil Engineering Research Institute for Cold Region/Japan. Based on the results of these studies, the first high-mound composite seawall was constructed for shore protection in the Shinkawa area of Mori Port in Japan.
