摘要：

海岸带是动态地区，由于众多因素，包括海平面的上升、波浪与洋流的类型、飓风乃至人类的影响，海岸地区经常受到变动。2004年12月26日巨大海啸席卷了堪雅库玛里至奥瓦利之间的海岸。当海浪冲上海滩时波高达30英尺。许多人因为巨浪的冲击和退浪的强力推拉而淹死在海里,许多村庄被毁。死亡总数超过300人,而且财产损失严重。海啸的规模与洋底移动的面积、移动距离是有关系的。该区显示为海成阶地、沙丘、滩脊、河口、洪积平原、海滩、红树林、准平原、高地、海蚀崖等等。我们试图通过现场在线勘查、政府记录以及采用遥感技术所做的海岸地貌研究等资料，通过海滩剖面测量和海岸环境的变化，进行海岸线动力学研究。文中也对主要的破坏予以认定。

Abstract:

 Coastal zones are dynamic areas that are constantly undergoing change in response to a multitude of factors including sea level rise, wave and current patterns, hurricanes and human influences. On 26th December 2004, huge waves smashed across the shore between Kanyakumari and Ovari. As they crossed the beach, the waves up to 30 feet tall. Many people are dead due to crush and pull to sea and drowned as the mighty waves withdraw. Many villages have been obliterated, the death tale could exceed 300 but the damage to the property is very high. The size of the tsunami is related to the area that moves on the ocean bottom and how far it moves. This region is manifested with marine terrace, sand dunes, beach ridges, estuaries, floodplains, beaches, mangroves, peneplains, uplands, sea cliff, etc. We have attempted the shoreline dynamics using beach profile survey, and coastal environment changes through online survey, governmental. records and coastal geomorphological studies using remote sensing technique. The major destructions are identified in this paper.
