破坏性海啸会摧毁沿海建筑物并移动大量海啸残骸。我们目前对海啸流中海啸碎片运动的了解有限。在本文中，我们对模型碎片在海滩上的孤波作用下的运动进行了初步的实验室研究。在各种条件下检查了最大淹没水线与残骸最终位置之间的差异。研究了孤立波高度、水深和碎片源到海岸线的距离对最大淹没、碎片极限和碎片最终位置的影响。一般来说，碎片的最终位置与最大淹没时的水线不同，并且近海海水退入大海而携带大量碎片的可能性很小。
Destructive tsunamis can destroy coastal structures and move huge amounts of tsunami debris. Our current understanding of motion of tsunami debris in tsunami flows is limited. In this paper, we present a preliminary laboratory study of motion of model debris under the action of solitary waves running up a beach. The difference between the waterline of maximum inundation and the final position of debris was examined under various conditions. Effects of solitary wave height, water depth, and the distance of debris source to the shoreline on the maximum inundation, the debris limit, and the final position of debris were examined. In general, the final positions of the debris are different from the waterline at maximum inundation and there is a low possibility that a large amount of debris can be carried by retreating water offshore into the sea.
