Abstract/Summary

BGS Coasts and Estuaries Geohazards program provides independent and expert geoscientific tools and advice for collaborative decision making to assess different adaptation options for coastal flooding and erosion. Globally, most people live within a few hours’ travel of a coast or an estuary. Because of their access to marine resources and opportunities for transport, trade and recreation, coasts and estuaries are major concentrations of population and investment and are the greatest concentration of assets anywhere on the planet. They provide enormous resources, not only in relation to minerals, energy, habitats and food, but also as a recreational amenity. Such resources and societal assets are threatened by a range of hazards, including marine flooding (the greatest flood risk in the UK), erosion and contamination. Long-term environmental changes, including societal pressures and climate change, are threatening the processes and functions of the coast upon which we depend. Climate change will also have an enormous impact on coastal stability. Associated changes in the ocean climate are changing the frequency and scale of storm surges in the short term and, in the longer term, increases in sea level pose major threats to coastal areas. The characterisation of geological processes, resources and hazards on the coast is essential in understanding how coasts are likely to change under future environmental and management scenarios. BGS Coasts and Estuaries combine the use of innovative 4D simulation models and cost-effective monitoring approaches (i.e. from space and using non-intrusive survey methods) to quantitatively assess the effects of different adaptation options against coastal flooding and coastal erosion (for example non-active intervention, managed realignment, hold the line, advance the line) with an emphasis on the transition from traditional grey engineering (such as hold the line with hard defences) to more green engineering (a combination of sand-scaping and giving space to coastal processes). The knowledge and data we acquire serve business, government and wider society to make better-informed decisions about coastal risks and opportunities.
