Technical Summary

Coastal zones are at particular risk from climate change because of the potential effects of sea-Ievel rise on the structure and distribution of a range of natural, rural and urban landscapes. The challenge taken up here is to explore how the predicted impacts of sea level rise on the geomorphology, biodiversity and socio-economic activities of the East Anglian coastline can be integrated in a Regional Coastal Simulator so that all the relevant policy options can be explored. Specifically this project provides two key elements for a Regional Coastal Simulator: biodiversity and off-shore coastal defence.

The coastline of East Anglia is of critical importance for biodiversity within the UK. An assessment will be made of the predicted impacts of sea level rise on that biodiversity and on how biodiversity changes can be related to changing geomorphology and socio-economic activities within the Coastal Simulator at a range of scales. Particular attention will focus on the wildfowl and wading birds that are of international importance within the region, linking predicted changes in sea level to sediment transport, population models and biodiversity management responses. Sediment transport and dynamics are seen as critical components of the Coastal Simulator affecting both biodiversity and coastal geomorphology. Computational fluid dynamics will be used to explore the possible use of off-shore sea-guides and naturally grown islands or peninsulas to protect vulnerable areas of coastline. A range of computer simulations will be used to identify optimum sea-guide configurations and the potential for inducing self-accretion of sand to protect vulnerable coasts.
