摘要
2004年发生的印度洋海啸给印度洋沿岸的亚非13个国家造成巨大的经济损失。多份实地考察报告都表明了红树林具有保护海岸的作用。就此,研究海啸波(孤立波)穿过红树林后透射波和反射波的变化情况,实验结果表明:透射波高随着入射波高的增大而增大,随着红树林分布密度的增大而减小;对于一定分布密度的红树林,反射系数和透射系数对入射波高不敏感。
The Indian Ocean tsunami on 26 December 2004 resulted in a great loss in 13 Asian and African countries. And most reports emphasize the protective function of coastal mangrove with actual observations after the 2004 tsunami catastrophe. In this paper, the transmission of tsunami waves （solitary wave） through mangrove forest is studied experimentally. It is found that the height of transmitted solitary waves increases with increasing incident wave height and decreases with increasing density of mangrove forest. Reflection and transmission coefficients are found to be insensitive to the incident wave height for a given density of mangrove forest.
