New project to help predict the future of the UK's coastline

A new project is being launched that will help forecast what the UK's coastline will look like in the future, up to 100 years' time.

The four-year £2.9m iCoast project is bringing together a number of UK universities, research laboratories and leading consultants, to develop new methods that will characterise and forecast long-term changes to coastal sediment systems. This work is funded by the Natural Environment Research Council and is partnered by the Environment Agency (EA), who will use these methods to improve long-term flood and erosion risk management.

UK coastal areas are at greater risk of flooding and erosion than their landward equivalents and degradation of their geomorphic systems, due to sediment starvation and/or climate change, could greatly increase these risks.

Previously, the ability to analyse and forecast geomorphic changes was limited. However, thanks to improvements in the analysis of coastal and offshore landform behaviour, the iCoast project will look to develop and implement models that can provide a breakthrough in the prediction of coastal behaviour under conditions of change. These behavioural landform models will be capable of coupled application at regional scales to resolve key reactions between climate forcing, sediment supply, morphology and erosion, and flood risk.

These models will be achieved through four work streams:

Robert Nicholls, Professor of Coastal Engineering at the University of Southampton, says: "The challenge posed by climate change requires a paradigm shift in our approach to coastal erosion and flood risk management. These changes intensify the need to understand and predict processes of change in shoreline position and configuration at management (decadal to century) scales.

"The iCoast project aims to improve this situation by bringing together formalised knowledge of coastal systems with quantified broad-scale analysis, with the systems insights from a new generation of reduced complexity models. This has the potential to deliver long-term coastal engineering and management solutions, which are relevant to coastal managers."

The iCoast project grew out of previous work by the Tyndall Centre's Coastal Simulator, which assessed how coastal changes physically affect a region and the impacts of flooding and erosion, and the joint Defra/EA Flood and Coastal Erosion Risk Management R&D programme, which funded the Estuaries Research Programme (ERP) that laid the groundwork for a lot of hybrid coastal morphology modelling ideas and project SC060074 on characterisation and prediction of large-scale, long-term change of coastal geomorphological behaviours.
