“…These three SLR trend were adopted in the analysis. The future wave heights with 50 years return period, estimated from wave simulations from 2075 to 2100 will increase by 1.23 times compared to the present offshore wave heights around Kochi Prefecture [Shimura et al, 2011]. According to the projection, the present design wave height of 13.0 m is multiplied by 1.23 in 87.5 years time as shown in Fig.…”

“…According to the projection, the present design wave height of 13.0 m is multiplied by 1.23 in 87.5 years time as shown in Fig. 6 together with two other lines representing plus and minus one standard deviation to the mean trend mean trend [Shimura et al, 2011]. The highest trend line is denoted as WA-L, the mean trend as WA-M and the lower trend as WA-S.…”

“…For evaluation of climate change effects on seawall failure, the target seawall is set considering a real seawall installed on the coast of Kochi Prefecture, Japan, facing the Pacific Ocean which is exposed to extreme waves [Shimura et al, 2011]. Figure 3 shows the seawall at the site.…”

Crown heights of seawalls should be designed to suppress overtopping discharge to a permissible level. The permissible level is determined from viewpoints of the structure types of coastal seawalls and hinterland use. It is usually difficult to design the crown heights of seawalls, especially in the present time where climate change due to global warming is expected. This study analyzes climate change effects such as sea level rise (SLR) and increase of waves and surges on the failure probability of seawalls under various conditions of crown height, toe depth and slope by using a Level III reliability analysis. It was found that the difference of SLR trends (fast, medium or low) has less impact on overtopping rates than the differences in wave height change for a seawall at a target location.
