Recently, precast concrete has been used in construction of seawall instead of cast-in-place concrete. It has several advantages such as shortening of construction period, cost reduction and the point of landscape and environmental view. Inaddition, it is possible to process precast concrete face in order that seawall has the artificial roughness for landscape as well as disaster prevention. In this study, hydraulic model experiments have been conducted to investigate hydrodynamic characteristics of a seawall with artificial roughness. Runup height and wave pressure on a seawall with artificial roughness have been discussed in relation with slope of seawall, incident wave condition and water depth, in comparison with those on smooth-face seawall.
