Vegetation was planted on the cliffs to further stabilise them from mass movement. Hurricane Katrina Case Study. Cliff stabilisation has had a positive impact in managing the threat of mass movement. In order to protect the cliffs along the front of Mappleton from undercutting, their gradient was also reduced artificially. This is evident in the image below. During the winter they have only a thin layer of sand covering the underlying clay, and in high summer the beaches build up enough for recreational purposes.
Generally, the natural beaches of Holderness are almost always narrow and unable to stop wave erosion. The census indicated that the parish of Mappleton had a population of , and increase from in Coasts menu Where do you want to go now? Drainage Basin Hydrological System. The Holderness Coast is located on the east coast of England. It is an excellent example of a spit. The processes of erosion and weathering occurring are numerous but include hydraulic action, freeze thaw, abrasion, solution and carbonation on the clay This has left a bay where the clay is and a headland jutting out to sea at Flamborough head.
The weak clay, stormy nature of the North Sea, and rising sea levels of 4mm per year mean that the future is bleak for parts of this coastline. The Holderness Coast is located on the east coast of England.

Following the construction of defences, they increased to 3. An annotated photograph to show the coastal management techniques used the protect Mappleton and their impact click to landfroms.
Coastal Processes What is coastal erosion? Coastal Landforms of Deposition. Underlying the Holderness Coast is bedrock made up of Cretaceous Chalk. Generally, the natural beaches of Holderness are almost always narrow and unable to stop wave erosion.
The soft boulder clay underlying Hornsea provides clear evidence of the erosional power of the sea. 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.
Drainage Basin Hydrological System. At Holderness the environment is primarily one of fetch-limited wind wave development, the dominant wave direction is north-easterly, creating a north-south orientated net longshore landfirms. Hurricane Katrina Case Study. View The Holderness coastline in a larger map. Coastal fieldwork Find out about coastal fieldwork techniques. Notice the impact of erosion to the south of the coastal defences. The Holderness Coast is located on the east coast of England.
The first is the result of the strong prevailing winds creating longshore drift that moves material south along the coastline. What is coastal deposition?

There are two main reasons why this area of coast is eroding so rapidly. In order to protect the cliffs along the front of Mappleton from undercutting, their gradient was also reduced artificially.
They are narrow as the result of the lack of major rivers bringing new sediment into the coastal budget. As the movement of sediment has been disrupted due to the construction of the stone groynes material previously feeding the beaches to the south of the Mappleton is restricted.
The rock armour revetment has been very effective in protecting the cliff to the southern end of the settlement.
It was decided t6hat the cost of coastal defence for a village of only people was less than the cost of building a new road. Under lying the Holderness Coast is bedrock made up of Cretaceous Chalk. Mappleton is located on the Holderness Coast of East Yorkshire. What is coastal transportation? The second is that the cliffs are made of soft boulder clay which erodes rapidly when saturated.
