This process is called terminal groyne syndrome and happens frequently when groynes are stopped. The exposed chalk of Flamborough provides examples of erosion, features such as caves, arches and stacks. These are shown on the map below. Drainage Basin Hydrological System. The boulders are placed like a wall in a m line of defence along the shoreline.
This is because water enters cracks and pore spaces in the rock, adding weight and making it slump. The average annual rate of erosion is around 2 metres per year. For a named coast either hard or soft rock , describe its main features. The census indicated that the parish of Mappleton had a population of , and increase from in Defending the Holderness Coastline There is a debate about whether or not human beings should attempt to defend coastlines. Typhoon Haiyan Case Study. Generally, the natural beaches of Holderness are almost always narrow and unable to stop wave erosion.
The first is the result of the strong prevailing winds creating longshore drift that moves material south along the coastline.

The Holderness Coast is the most rapidly eroding coastline in Europe. It has the unenviable reputation as the number one place in Europe holrerness coastal erosion, and in a stormy year waves from the North sea can remove between 7 and 10m of coastline.

The coastline starts with blowholes, stacks and stumps at Flamborough, and culminates with Spurn head, a very large spit that runs across part of Humber Estuary. The coastline today is around 4km inland from where it was in Roman times, and there are many LOST villages of the Holderness coastline that have long disappeared into the sea.
It is this soft boulder clay that is being rapidly eroded. It works by absorbing syudy not levek — wave energy using large air spaces between the boulders and a broad surface area. They are narrow as the result of the lack of major rivers bringing new sediment into the coastal budget. These large granite boulders were imported from Scandinavia and deposited by barge along the coast.
