作者对2004年12月印度洋海啸在斯里兰卡基林达渔港造成的灾害进行了实地调查。在港口处观测到了严重的冲刷现象，这里过去被大量的泥沙堆积所覆盖。为了研究这一观察到的功能的物理机制，我们进行了数值分析，计算海啸传播，泥沙输运，并由此产生的海滩地形变化。模型预测成功地解释了在Kirinda观测到的地形变化，并指出，回流，集中在港口口，发挥了重要作用，造成广泛的冲刷在Kirinda渔港。
Authors carried out field survey of the disaster due to the Dec 2004 Indian Ocean Tsunami at Kirinda fishing port in Sri Lanka. We observed severe scour at the harbor mouth, where used to be covered by large amount of accumulated sediments. In order to investigate the physical mechanisms of this observed feature, we conducted a numerical analysis that computes tsunami propagation, sediment transport, and resulting beach topography changes. Model predictions successfully explained the topography change observed in Kirinda and indicated that the back-rushing flow, which concentrated at the harbor mouth, played significant role to cause extensive scours in Kirinda fishing port.
