一、绪言以前关于波浪与水流共同作用问题的研究,主要着眼于在有流场情况下对波浪理论进行探讨。在流场内沿垂直方向有流速分布,或者说流速沿垂线有变化。多数人认为,由于水流的作用,波浪特性发生了变化。与此相反,有关波浪与水流共同作用的试验研究却很少,没有进行相应的试验研究以验证理论的正确性。更进一步说,波动对水流有干扰,即由于波动的存在使水流流速的分布和 I. INTRODUCTION The previous research on the interaction between wave and water mainly focused on the discussion of wave theory in the presence of a flow field. In the flow field in the vertical direction there is a flow velocity distribution, or flow velocity along the vertical change. Most people think that the wave characteristics have changed due to the effects of water currents. In contrast, there are few experimental studies on the interaction between waves and currents, and no corresponding experimental studies have been carried out to verify the validity of the theory. Furthermore, fluctuations have an interference with the flow of water, which means that the distribution of flow velocity and
