2013年12月5日，英国海岸线经历了有史以来最大的风暴潮之一。这场风暴造成了严重的海岸侵蚀，特别是在北海沿岸，欧洲大陆和英格兰东海岸之间的漏斗加剧了向南移动的浪涌。本文的研究重点是位于林肯郡海岸Mablethorpe北部的一个油田（北纬53°21′43”东经0°15′03”），该油田经历了长期（1891-2010年）平均每年200万的吸油量（Montreuil and Bullard， 2012年）。在12月5日风暴事件发生前，沿海前沙丘发育良好，主要前沙丘高度可达3.5m，次级（内陆）沙丘高度可达7m。风暴潮将沙丘横向侵蚀了20米，形成了高达2米的垂直峭壁。如果没有进一步的风暴潮，预计沙丘系统将逐渐恢复，悬崖最终将被填满。该研究项目的总体目标是结合高分辨率地形和环境数据，量化该地点风暴后海岸恢复的速度和性质。本文利用这个项目来强调现代地理方法如何用于近距离详细监测沿海现象。这些方法包括地面激光扫描（TLS）和近景数字摄影测量，后者结合了最新的运动结构（SfM）技术。
On 5 December 2013, the UK coastline experienced one of the biggest storm surges on record. This storm caused substantial coastal erosion, particularly along the North Sea coast where the southwards travelling surge was heightened by funnelling between the European mainland and the East Coast of England. This paper focuses on a field site located north of Mablethorpe on the Lincolnshire coast (53°21’43”N 0°15’03”E) which has undergone long-term (1891-2010) accretion of, on average, 2m yr-1 (Montreuil and Bullard, 2012). Prior to the 5 December storm event, well-developed coastal foredunes were present with primary foredunes up to 3.5m ODN and secondary (inland) dunes up to 7m high. The storm surge eroded the dunes laterally by up to 20m, creating a vertical scarp face up to 2m high. Provided there are no further storm surges, is expected that the dune system will gradually recover and the scarp will eventually be infilled. The overall aim of this research project is to combine high resolution topographic and environmental data to quantify the rate and nature of post-storm coastal recovery at this site. This paper draws upon this project to highlight how modern geomatic methods can be used for detailed monitoring of coastal phenomena at close range. These methods include both terrestrial laser scanning (TLS) and close range digital photogrammetry, which incorporates the very latest structure from motion (SfM) techniques.
