Design requirement for mixed sand and gravel beach defences under scenarios of sea level rise

摘要

Along many coastlines of the world, beaches provide the primary defence against flooding or erosion with their fate under rising sea levels still only poorly researched. This is particularly the case for the coastline of Southeast England, where similar to 190 km of shingle barriers protect low-lying hinterland or a coastal plain that is at or barely above the present reach of waves.
