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.
