Erosion is a problem because of geology, the fetch and longshore drift.
The Holderness coast has two rock types; chalk and boulder clay. The chalk at Flamborough Head is fairly resistant and produces features such as cliffs, caves, arches and stacks. The rest of the coast is boulder clay which has little resistance to…
