The purpose of the present project is to develop methodologies appropriate to the description of coastal evolution under a changing climate around the UK. This will be achieved by a combination of improved physical understanding of the coastal system and advanced statistical and numerical techniques. In integrating the detailed modelling of coastal processes into long-term climate prediction, the research outcomes will provide the necessary tools to predict coastal change intime scales ranging from 100s to 100,000s years. The main objectives of the project are summarised as follows:Develop process-based simulations of coastal change using dynamically downscaled global climate around UK coasts. Incorporate human interventions (coastal protection structures) and additional sediment source/sink terms in coastal evolution modelling. Dimensional reduction of morphodynamic loops using improved physical understanding and advanced statistical methods (surrogate modelling, storm sequencing). Provide am improved representation of coastal change in short-term time scales (100s of years) under climate change scenarios obtained from IPCC predictions. Integrate the short-term methodology into long-term predictions (100,000s of years). Quantify the uncertainty in models.This information will provide critical insights regarding the selection and assessment of coastal sites as potential Geological Disposal Facilities and provide a sound basis for assessing their safety in the long term.

本项目的目的是开发适合描述英国周围气候变化下沿海演变的方法。这将通过提高对沿海系统的物理认识和先进的统计和数字技术相结合来实现。将沿海过程的详细模拟整合到长期气候预测中，研究成果将为预测100万年至10万年的沿海变化提供必要的工具。该项目的主要目标总结如下：利用英国海岸周围动态缩小的全球气候，开发基于过程的海岸变化模拟。在海岸演变模型中纳入人为干预（海岸保护结构）和附加的沉积物源/汇术语。利用改进的物理理解和先进的统计方法（替代模型，风暴排序）减少形态动力学环的维度。在从IPCC预测中获得的气候变化情景下，提供短期时间尺度（100年）沿海变化的改进表示。将短期方法整合到长期预测中（10万年）。量化模型中的不确定性。这些资料将为选择和评估作为潜在地质处置设施的沿海地点提供重要的见解，并为评估其长期安全性提供可靠的基础。
