Abstract
We are developing the wave overtopping type wave power generation which is wave energy is converted into potential energy by letting waves run up along the slope, the water level becomes different between the experimental water tank and peripheral sea area, and flow energy is generated. We reported the relation of the volume of overtopping for various waves in the past this time, the simulation about wave feeding into this overtopping-type wave-power generation model for various irregular waves and regular waves are reported. It is evident that Qm increased with increasing wave energy regardless of the wave type, and the pipe length 5D has high drainage characteristics. It was also suggested that Qm has a tendency to be larger for irregular waves.
