This paper deals with board named "wavedozer". The name was after because of similar operations. According to the linear theory of waves, the wave profiles made by wavemaking board depend on the depth of water h, the stream velocity C, the incident angle of board θ and the wetted chord length of board l_w. The relations between the wavemaking parameters as mentioned above and the wave profiles were investigated. The experimental wave profiles were compared with the theoretical ones and both were in good coincidence. In Appendix 1 and 2, the outline of calculation in linear wave theory was explained. The tentative model of pressure used in the theoretical calculation was examined by measuring the pressure distributions on the wavemaking board. Also, the distribution of x-component orbital velocities was measured and the inner structures of waves were roughly compared with the theoretical ones. Through this series of experiments it was verified that the stationary waves in a circulating water channel had almost the same characteristics as those of the theoretical waves.
