This process is called terminal groyne syndrome and happens frequently when groynes are stopped. As the result of this the beaches to the south have very little sediment and during low tide expose a combination of sand and clay boulders that have been eroded from the cliffs. The Holderness Coast is the most rapidly eroding coastline in Europe. You can clearly see the area to the south has very gently sloping beaches and high levels of erosion where the coastal defences stop. Indeed, today, farmland, tourist sites such as caravan parks and villages remain under threat.
As the result of this the beaches to the south have very little sediment and during low tide expose a combination of sand and clay boulders that have been eroded from the cliffs. It works by absorbing — not reflecting — wave energy using large air spaces between the boulders and a broad surface area. However, in most place this is covered by glacial till deposited over 18, years ago. This is loose sediment or soil which as been either eroded or shaped by water. BBC Bitsize footage – Holderness coast. Defending the Holderness Coastline There is a debate about whether or not human beings should attempt to defend coastlines. The exposed chalk of Flamborough provides examples of erosion, features such as caves, arches and stacks.

There are two main reasons why this area of coast is eroding levrl rapidly. The rock armour revetment has been very effective in protecting the cliff to the southern end of the settlement.

A number of farmers have lost a significant amount of land to increased rates of erosion. Drainage Basin Hydrological System. Holderness Coast – Study Page.
Mappleton is an excellent case study of an attempt at coastal management which has a negative impact further along the coast. 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 average annual rate of erosion is around 2 metres per year.

This is evident in the image below. To get a better experience, try one of the supported browsers listed here. They are narrow as the result of the lack of major rivers bringing new sediment into the levsl budget. What is the rate of erosion at Barmston? Click on the image for a clearer picture.
In order to protect the cliffs along the front of Mappleton from undercutting, their gradient was also reduced artificially. The area contains ‘text book’ examples of coastal erosion and deposition. This is known as cliff stabilisation. Firefly needs a modern browser, so you may notice acse look broken right now.
These are shown on the map below. These large granite boulders were imported from Scandinavia and deposited by barge along the coast.
