Abstract
Characteristics of a flexible-type submerged floating breakwaterwitha pressurized airchamber under wave action and wave transformations are investigated experimentally. As flexibility of the structure and floating motion depend on air pressureinthe air-chamber, decreasing, airpressure means to increase of membrane movement and floating motion. Since the dynamic motion generate radiation wave, wave transmission tends to be smaller in order to the interaction of the wave and incident wave. The type of the floating can decrease wave transmission relatively.
