SWANAGE CASE STUDY GCSE

They reflect waves back out to sea preventing erosion of the cliff. But, by stopping the movement of beach material along the coast beaches further down the coast are becoming narrower and subject to more erosion due to reduced ability to absorb wave energy. Groynes Groynes are wooden or stone barries which are built at right angles to the coast. There is also a risk for people from landslides and rockfalls. Towards the northern end of the bay the cliffs are covered in vegetation, stablising them and protecting them from erosion.

The area around Swanage is made up of bands of hard and soft rock. Coastlines where the geology alternates between bands of hard and soft rock which are perpendicular to the shore are called discordant coastlines. A concordant coastline has the same type of rock along its length. Longshore drift affects the bay carrying material mainly gravel from the south to the north of the beach. Chemical weathering and erosion are gradually wearing down these down. Dorsert is located on the southern coast of the UK. Concrete sea walls are in place along most of Swanage beach.

Coastal landforms – AQA – Revision 3 – GCSE Geography – BBC Bitesize

How are geomorphic processes creating coastal landforms? They trap material being transported by longshore drift to create larger beaches which can then absorb wave energy to reduce erosion rates.

Behind the limestone is a layer of clay which is softer so more easily eroded. Chesil Beach is an example of a bar.

The area around Swanage is made up of bands of hard and soft rock. Dorsert is located on the southern coast of the UK. The alternating bands of hard and soft rock run parallel to the coast. It connects the Isle of Portland to the mainland. It is unusual as it has formed parallel to the coastline.

The Foreland, Old Harry and his Wife: However, this creates a strong backwash which removes sediment from the beach and can lead to erosion under the wall. It is called the Jurassic Coast as it has lots of fossils dating back to the Jurassic period.

Sea wall Concrete sea walls are in place along most of Swanage beach. Erosion is the dominant process in the bay with the beach losing material year on year. Biological weathering caused studdy the vegetation on the top of the headland is also breaking up swanabe rock.

The arch is gradually being worn away by mechanical, chemical and biological weathering. As areas of the Dorset coast are being eroded, properities and infrastructure are at risk.

But, by stopping the movement of beach material along the coast bcse further down the coast are becoming narrower and subject to more erosion due to reduced ability to absorb wave energy.

Dorset – case study of a UK coastal landscape

The bands of soft rock erode more quickly than those of the more resistant hard rock leaving a section of land jutting out into the sea, called a headland. How do climate and geolgy influence geomorphic stud The areas where the soft rock has eroded away, next to the headland, are called bays.

Behind the spit there is The Fleet, a lagoon. The entrance to the cove is narrow where the waves have cut through weaknesses in the resistant limestone. Dorset is located in the south of England.

In the wintersand and shingle were dredged from the sea bed at Poole Harbour and added to the upper parts of Swanage beach creating a wider beach.

At the back of the cove is a band of more resistant chalk, so erosion is slower here.

Coastal management strategies are being used along the Dorset coastline to prevent erosion in some areas but they have impacted the landscape and casr changes to the natural environment. Lulworth Cove is situated on the south coast of England, on a concordant coastline.

An arch at the end of the headland has collpased to form a stack called Old Harry and a stump called Old Harry’s Wife.

This means waves are slowed, reducing erosion and will help to protect proprties and cliffs. Chemical weathering and erosion are gradually wearing down these down. This caused the formation of Old Harry, a stack.
