This paper examined the reduction effects of wave force and overtopping of a porous barrier installed on a vertical seawall. The laboratory experiments of green water overtopping at a low crest seawall with a barrier were carried out under a range of test conditions; the barrier parameter ranging from 0% to 100%, the relative seawall freeboard ranging from 0.35 to 1.45, the wave steepness ranging from 0.014 to 0.03, the relative water depth ranging from 2.9 to 6.5. The test results show that the reductions of the wave force and overtopping discharge due to the porous barrier are mainly governed by the barrier parameter and the relative freeboard. The reduction effects are influenced by a variation in the wave runup induced by porous barrier installation.
