The regular wave interaction with a double concentric porous circular cylinder system consisting of an inner impermeable cylinder and an outer perforated cylinder was studied through physical model study. The experiments were carried out on the the double cylinder model in a wave flume to study the runup and rundown at the leading and trailing edges of the perforated cylinder. It was found that the maximum wave runup on the perforated cylinder is almost the same as the incident wave height. The predictive formulae were also developed for the wave runup and rundown on the perforated cylinder, which can be easily used for design applications.
