GCSE GEOGRAPHY SWANAGE CASE STUDY

Behind the spit there is The Fleet, a lagoon. It has been created by longshore drift. Coastal management strategies are being used along the Dorset coastline to prevent erosion in some areas but they have impacted the landscape and caused changes to the natural environment. 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. Lulworth Cove is situated on the south coast of England, on a concordant coastline. New timber groynes were installed on Swanage beach in and have reduced the loss of beach material.

The arch is gradually being worn away by mechanical, chemical and biological weathering. The areas where the soft rock has eroded away, next to the headland, are called bays. This is made of chalk which is a harder rock. Over time Old Harry will collapse to form a stump. Its coastline has examples of many erosional and depositional landforms.

They reflect waves back out to sea preventing erosion of the cliff. Towards the northern end of the bay the cliffs are gwography in vegetation, stablising them and protecting them from erosion.

Dorset – case study of a UK coastal landscape

How do climate and geolgy influence geomorphic processes? However, casw creates a strong backwash which removes sediment from the beach and can lead to erosion under the wall.

Behind the spit there is The Fleet, a lagoon. Biological weathering caused by the vegetation on the top of the headland is also breaking up the rock.

An Examination of the coast line in the Swanage Area.

At the back of the cove is a band of more resistant chalk, so erosion is slower here. Sea wall Concrete sea walls are in place along most of Swanage beach. How is human activity, including mangement, working in combination with geomorphic processes to shape the landscape?

The Foreland, Old Harry and his Wife: Erosion is the dominant process in the bay goegraphy the beach losing material year on year. Over time Old Harry will collapse to form a stump. This is made of chalk which is a harder rock. The arch is gradually being worn away by mechanical, chemical and biological weathering.

It is called the Jurassic Coast as it has lots of fossils dating back to the Jurassic period. As areas of the Dorset coast are being eroded, properities and infrastructure are at risk. New timber groynes were installed on Swanage beach in and have reduced the loss of beach material. Behind the limestone is a layer of clay which is softer so more easily eroded. Coastal management strategies are being used along the Dorset coastline to casse erosion in some areas but they have impacted the landscape and caused changes to the natural environment.

Dorset is located in the south of England. Beach replenishment 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. 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.

The area around Swanage cxse made up of bands of hard and soft rock. Groynes Groynes are wooden or stone barries which are built at right angles to the coast.

The areas where the soft rock has eroded away, next to the headland, are geographu bays. A concordant coastline has the same type of rock along its length.

It connects the Isle of Portland to the mainland. Lulworth Cove is situated on the south coast of England, on a concordant coastline.

This caused the formation of Old Gcde, a stack. 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. The headland is made out of chalk, a hard rock. How are geomorphic processes creating coastal landforms? Dorsert is located on the southern coast of the UK. The headland juts out into the sea, so sawnage is more vulnerable to high-energy waves. They trap material being transported by longshore drift to create larger beaches which can then absorb wave energy to reduce erosion rates.

This means waves are slowed, reducing erosion and will help to protect proprties and cliffs.
