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。
Coastal zones are dynamic and coastal areas are often subject to change due to many factors, including rising sea levels, the types of waves and currents, hurricanes and even humans. December 26, 2004 A huge tsunami swept the coast between Canakumari and Orvali. When waves hit the beach waves up to 30 feet. Many people drowned in the sea because of the impact of waves and the powerful push and pull of waves, and many villages were destroyed. The total number of deaths was over 300 and the property suffered serious losses. The size of the tsunami and the area of the ocean floor to move, the distance is related. The area is shown as a sea terrace, sand dune, beach ridge, estuary, alluvial plain, beach, mangroves, quasi-plains, highlands, sea cliffs and so on. We try to study coastline dynamics through on-site online surveys, government records, and coastal landform studies using remote sensing techniques, through beach profile surveys and changes in the coastal environment. The text also identifies major disruptions.
