For a wave flume with a piston-type wave maker, a method of generating concentrated waves of arbitrary waveform at arbitrary locations in a channel is proposed based on the theory of linear systems using frequency response function and impulse response function from linear wavemaker theory. The results are compared with those of CADMAS-SURF/3D, a numerical wave tank, and show that the proposed method can be used in experiments, although the waveform is affected by nonlinearity. The present method can be applied not only to physical experiments but also to the wave generation of arbitrary waveforms in numerical wave tanks, which have recently become widely used in practical design.
