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.

本文从沿岸海域水交换的角度，对规则波中有限宽倾斜平板后的诱导定常流进行了实验研究。通过对平板上水流和波浪爬高的测量，以及自由表面流动的流动显示，改变波浪条件和平板尺寸，研究了稳定流产生的机理。并对二维水槽内的流动进行了测量，以考察二维条件下定常流动的发生。结果表明：1）规则波中倾斜平板后的定常流动仅在三维条件下发生; 2）平板上尖点形式的波浪爬高与定常流动的发生有密切关系; 3）平板坡度和波浪周期对波浪诱导的定常流动起主导作用。
