Coastal zones attract settlements, are ideal for a range of economic activities and accommodate important natural habitats that provide ecosystem services. All these coastal activities are vulnerable to climate and other changes unless appropriate management policies are implemented. Sea-level rise and intensified storms could increase the incidence of flooding and erosion, as well as degrade coastal ecosystems. Importantly, the coast is a linked system, and management responses for one area or sector may influence the impacts for other areas or sectors. Understanding coastal processes and taking account of climate and socio-economic futures helps to illustrate/reveal impending choices, and in developing responsive informed long-term coastal management policies. This paper describes research being carried out by the Tyndall Centre for Climate Change Research on their Coastal Simulator. The research includes the linkage of a range of modelling procedures to represent coastal management and climate and coastal processes, as well as the design of a GIS-based interface to make the intergrated results accessible. The prototype simulator provides regional impact assessments of climate and socio-economic futures under various management options in the coastal zones of Norfolk, East Anglia and shows that erosion and flood risk are strongly linked.
