GCSE GEOGRAPHY SWANAGE BAY CASE STUDY

This is made of chalk which is a harder rock. It is called the Jurassic Coast as it has lots of fossils dating back to the Jurassic period. At the back of the cove is a band of more resistant chalk, so erosion is slower here. Lulworth Cove is situated on the south coast of England, on a concordant coastline. In the winter , sand and shingle were dredged from the sea bed at Poole Harbour and added to the upper parts of Swanage beach creating a wider beach. How are geomorphic processes creating coastal landforms?

This means waves are slowed, reducing erosion and will help to protect proprties and cliffs. Sea wall Concrete sea walls are in place along most of Swanage beach. The limestone cliffs forming the back wall of the cove are vulnerable to mass movement and sometimes experience small slides and slumps. The headland juts out into the sea, so it is more vulnerable to high-energy waves. Towards the northern end of the bay the cliffs are covered in vegetation, stablising them and protecting them from erosion. 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. Beach replenishment In the winter , sand and shingle were dredged from the sea bed at Poole Harbour and added to the upper parts of Swanage beach creating a wider beach.

They reflect waves back out to sea preventing erosion of the cliff. It is called the Jurassic Coast as it has lots of fossils dating back to the Jurassic period. Erosion is the dominant process in the bay with the beach losing material year on year. 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.

Concrete sea walls are in place along most of Swanage beach. The arch is gradually being worn away by mechanical, chemical and biological weathering. A cade coastline has the same type of rock along its length.

The headland is made out of stjdy, a hard rock. How do climate and geolgy influence geomorphic processes? Biological weathering caused by the vegetation on the top of the headland is also breaking up bxy rock. Groynes are wooden or stone barries which are built at right angles to the coast. At the back of the cove is bau band of more resistant chalk, so erosion is slower here. Towards the northern end of the bay the cliffs are covered in vegetation, stablising them and protecting them from erosion.

This is made of chalk which is a harder rock. This caused the formation of Old Harry, a stack. The entrance to the cove is narrow where the waves have cut through weaknesses in the resistant limestone.

Longshore drift affects the bay carrying material mainly gravel from the south to the north of the beach. It connects the Isle of Portland to the mainland.

The area around Swanage is made up of bands of hard and soft rock. The Foreland, Old Harry and his Wife: The soft rock is made of clay and sands, and the hard rock is chalk and limestone.

As areas of the Dorset coast are being eroded, properities and infrastructure are at swanaeg. It is unusual as it has formed parallel to the coastline.

An Examination of the coast line in the Swanage Area.

New timber groynes were installed on Swanage beach in and have reduced the loss of beach material. Lulworth Cove is situated on the south coast of England, on a concordant coastline. Over time Old Harry will collapse to form a stump. How is human activity, including mangement, working in combination with geomorphic processes casse shape the landscape?

Erosion by waves opened up a crack in the headland, which then became a cave and eventually an arch. This means waves are slowed, reducing erosion and will help to protect proprties and geogralhy.

The limestone cliffs forming the back wall of the cove are vulnerable to mass movement and sometimes experience small slides and slumps. Dorsert is located on the southern coast of the UK.

Groynes Groynes are wooden or stone barries which are built at right angles to the coast. Because there’s no erosion, there is no material to replenish the beach meaning the beach level will become lower. How are geomorphic processes creating coastal landforms?

Coastal Case Studies

They trap material being transported by longshore drift to create larger beaches which can then absorb wave energy to reduce erosion rates. Chesil Beach is an example of a bar. 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.
