- Abstract:
- Pressures on the coastal zone are increasing due to climate change, with sea-level expected to rise by 0.5 m over the next century. In the UK, sea defences and shore protection works around 4,300 km of coast cost approximately #325 million per year to maintain, a figure that will continue to rise in the future. Natural beaches are the 'best' form of coastal protection, hence the popularity of beach nourishment (placing extra sand on the beach) as a management measure. However, our understanding of how beaches provide coastal protection is limited. It is well known that during storms, nearshore sand bars serve as natural submerged breakwaters and protect the beach from erosion. Coastal engineers and managers need to know more about how and under what conditions nearshore sand bars provide this natural protection. A crucial role is played by the cross-shore (on-offshore) exchange of sediment between the dry beach and the nearshore zone, and insight into this exchange is of vital importance to the understanding and modelling of beach systems. This study will contribute to this research area by undertaking unprecedented field experiments, data analysis and numerical modelling of cross-shore sediment transport processes and profile evolution on natural beaches. The principal aim of this research project is to improve our understanding of cross-shore sediment transport processes on planar (flat) and barred beaches. Two unprecedented data sets on cross-shore sediment transport will be collected from a plane beach (Sennen, Cornwall) and a barred beach (Theddlethorpe, Lincolnshire) by burying small high-technology instruments into the beachface. These instruments will provide continuous measurements of waves, currents, sediment suspension and beach response. Using a novel modelling technique the data will be used to form 'shape functions' that are passed back and forth over the beach with changes in the tides and waves, so altering the shape of the beach profile and allowing the prediction of erosion and accretion events. The project is a collaboration between scientists from the Institute of Marine Sciences at Plymouth University and the Geography Department at Loughborough University.
