Abstract
As commercial and residential areas are actively developed around the coastal area with excellent scenery, installing coastal structures such as seawalls and breakwaters is continuously increasing to secure safe coastal regions. Additionally, the increase in the intensity of natural disasters due to climate change may cause higher incident waves than in the past, which may further aggravate the damage caused by wave overtopping. In this study, compared to the existing vertical seawall, we investigated the effect of wave overtopping reduction of a recurved seawall, which actively reflects the incoming waves, through the hydraulic model test. As a result of the hydraulic model experiment, it was confirmed that there was an effect of up to 92.4% of wave overtopping reduction in average compared to the vertical seawall and structures covered with armor blocks.
