Wave flumes equipped with wave generating facilities are commonly used to perform various types of physical modeling in laboratories. The placement of wave absorbers near reflective boundaries of the flume is aimed to dissipate the energy of incoming waves. Failure to do so could affect significantly the uniformity of wave train and eventually winder the accuracy any of the experiment carried out in the flume. In. this study, aVertical Wave Screen System, (VWSS) is proposed to taclde the problem. Laboratory experiments had been conducted with aim to study the effectiveness of applying the VWSS as awave absorber in the wave flume. Aseries of laboratory test was carried out to investigate the wave reflection characteristics corresponding to the different number of wave screen, namely 4-screen, 8-screen and 12-screen. The laboratory investigations were conducted in the wave-only condition in the flume, which are subjected to steady monochromatic non-breaking waves throughout the experiments. Atotal of240 experiments runs were conducted relating all variable to the wave characteristics such as, wave height, water depth and wave period. Assessment of results was done to identify the performance and the limitation of the proposed wave absorber. Comparisons of wave energy absorbing performance in term ofreflection ofcoefficient, C, were also made in this study.
