This study dealt with experimental investigation on induced steady flow behind inclined flat plate having finite breadth in regular waves from the point of view of water exchange in coastal sea area. The mechanism of the occurence of the steady flow was investigated through the measurements of water currents and wave run up on the flat platle, and flow visualization of the flow on free surface, changing the wave conditions and dimensions of flat plate. Measurements of the flows in two-dimensional water tank were also carried out to examine the occurrence of the steady flow in two-dimensional condition. The results are as follows.1) The steady flow behind inclined flat plate in regular waves occurs only in three-dimensional condition,2) wave run up having the cusp form on the flat plate has a close realtion to the occurrence of the steady flow and3) the slope of the flat plate and the wave period have dominant effect on the wave induced steady flow.

这项研究介绍了从沿海海洋地区水交换的角度从常规波动中有限宽的倾斜平板后面诱发稳定流动的实验研究。通过测量水流和波浪在平板上的测量，以及自由表面上流动的流动可视化，改变了平板的波浪条件和尺寸。还进行了二维水箱中流量的测量，以检查在二维条件下稳定流量的发生。结果如下。1）在常规波中倾斜的平板后面的稳定流量仅在三维条件下发生，2）波浪在平板上的尖孔形式奔跑，在平板上的尖尖与稳定流动的发生密切接触，而3）平板的斜率和平板的斜率和波周期对波诱导的稳定流量具有显着效应。
