项目摘要

The project will involve the synthesis of a large number of environmental datasets, from historical archives (including aerial photography, historical and contemporary maps and in-situ field survey) to near real-time oceanographic data and newly available satellite imagery (including Copernicus Sentinel-2 imagery), to establish the temporal and spatial patterning of shoreline change on the 45 km-long barrier coastline of North Norfolk, eastern England. It will explore various aspects of geomorphological change including shoreline recovery from storm events, long term barrier dynamics, sediment budget calculations, washover and breakthrough occurrence and storm surge events. Bringing together these aspects will help to develop a comprehensive understanding of the North Norfolk coastal system and how it could change in response to future changes in natural drivers (such as sea level rise and storminess). The research will include the development of shoreline response models, and their coupling to storm surge models, to explore near-future shoreline positions; this will have implications for risk management at the coast and this will be explored with specific reference to impacts on ecosystems. In addition, the project will integrate the physical modelling with environmental hazard modelling, through the use of indicators of socio-economic vulnerability, to define new assessments of near-future risks to coastal communities and infrastructure. Visualisation techniques will be used as part of the communication of project results to a wide range of coastal managers and decision makers.

该项目将综合历史档案中的大量环境数据集（包括航空摄影、历史和当代地图以及现场实地调查）与近实时海洋学数据和新提供的卫星图像相结合（包括哥白尼哨兵2号卫星图像），以确定北诺福克45公里长的屏障海岸线上海岸线变化的时间和空间模式，英格兰东部它将探讨地貌变化的各个方面，包括从风暴事件中恢复海岸线、长期屏障动力学、沉积物收支计算、冲刷和突破发生以及风暴潮事件。将这些方面结合在一起将有助于全面了解北诺福克海岸系统，以及它如何应对未来自然驱动因素（如海平面上升和风暴）的变化。研究将包括开发海岸线反应模型，并将其与风暴潮模型相结合，以探索不久的将来海岸线的位置;这将对海岸的风险管理产生影响，并将具体探讨对生态系统的影响。此外，该项目将通过使用社会经济脆弱性指标，将物理建模与环境灾害建模相结合，以确定对沿海社区和基础设施近期风险的新评估。可视化技术将被用作项目结果与广泛的沿海管理者和决策者沟通的一部分。
