It extends 61km from Flamborough in the north to Spurn Point in the south. This is because water enters cracks and pore spaces in the rock, adding weight and making it slump. The second is that the cliffs are made of soft boulder clay which erodes rapidly when saturated. Notice the impact of erosion to the south of the coastal defences. To get a better experience, try one of the supported browsers listed here.
The impacts of coastal erosion on socio-economic aspects are: Cliff stabilisation has had a positive impact in managing the threat of mass movement. The Holderness Coast is one of Europe’s fastest eroding coastlines. Rates of erosion to the south of the defences at Mappleton have increased significantly since the construction of defences at Mappleton. The construction of the rock groynes has created a larger, higher sandy beach for Mappleton. For a named coast either hard or soft rock , describe its main features.
Timber groins, drains, seawall, revetments. 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.
What features of erosion are visible at Flamborough Head? An annotated photograph to show the coastal ckast techniques used the protect Mappleton and their impact click to enlarge.
Holderness Case Study Page
They are narrow as the result of the lack of major rivers bringing new sediment into the coastal budget. Hurricane Katrina Case Study. However, in most place this is covered by glacial till deposited over 18, years ago.
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 Holderness Coast Case Study – Internet Geography
The average annual rate of erosion is ccollapse 2 metres per year. For a named coast either hard or soft rockdescribe its main features.
Open this Word document and complete all of the tasks using the Google map below ; Find out more about coastal erosion at this excellent website. The Holderness Coast is located on the east coast of England. There are two main reasons why this area of coast is eroding so rapidly. However some defences have been attempted.
In addition to the cooast being vulnerable to erosion, it is also prone to slumping. It works by absorbing — not reflecting — wave energy using large air spaces between the boulders and a broad surface area.
The boulders are placed like a wall in a m line of defence along the shoreline. So, blocks of granite collase brought in and placed along the cliff base and 2 rock groynes were put into place to trap sediment stdy because of longshore drift. 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. 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.
Longshore drift tends to transport material south which has resulted in the formation of Spurn Point, a spit formed at the mouth of the Humber Estuary. Indeed, today, farmland, tourist sites such as caravan parks and villages remain under threat. Fliff area contains ‘text book’ examples of coastal erosion and deposition.
Revetments are very coplapse but long-lasting. This process is called terminal groyne syndrome and happens frequently when groynes are stopped. 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. Kerala flood case study.
There are two main reasons why this area of coast is eroding so rapidly. The Holderness Coast is the most rapidly eroding coastline in Europe. The rock armour revetment has been very effective in protecting the cliff to the southern end of the settlement. What is coastal transportation? The Holderness coast mainly consists of soft glacial drift cliffs, which have been cut back up to m over the last century.
However, in most places, this is covered by glacial till deposited over 18, years ago.
