This study investigates the amplifying characteristic of a wave activated pump through a series of hydraulic experiments. The wave activated pump consists of some vertical columns set in front of a vertical wall. This study confirms that the pump amplifies the wave motion effectively under irregular wave conditions as well as regular wave conditions. The magnitude of a maximum amplification factor depends on a distance between a seabed and the bottom end of the column. A mathematical model is
