GCSE GEOGRAPHY SWANAGE CASE STUDY

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 juts out into the sea, so it is more vulnerable to high-energy waves. Groynes are wooden or stone barries which are built at right angles to the coast. Biological weathering caused by the vegetation on the top of the headland is also breaking up the rock. Chemical weathering and erosion are gradually wearing down these down. Dorsert is located on the southern coast of the UK.

Because there’s no erosion, there is no material to replenish the beach meaning the beach level will become lower. Chesil Beach is an example of a bar. It has been created by longshore drift. Behind the spit there is The Fleet, a lagoon. 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. Biological weathering caused by the vegetation on the top of the headland is also breaking up the rock. How are geomorphic processes creating coastal landforms?

It connects the Isle of Portland to the mainland. Lulworth Cove is situated on the south coast of England, on a concordant coastline. Over time Old Harry will collapse to form a stump. The alternating bands of hard and soft rock run parallel to the coast. Then the cove widens where the softer clays have been more easily eroded.

Stucy the northern end of the bay the cliffs are covered in vegetation, stablising them and protecting them from erosion. Groynes are wooden or stone barries which are built at right angles to the coast. The spit has continued to join to the Isle of Portland. Biological weathering caused by the vegetation on the top of the headland is also breaking up the rock.

Casee coastline has examples of many erosional and depositional landforms. Because there’s no erosion, there is no material to replenish the beach meaning the beach level will become lower.

The headland juts out into the sea, so it is more vulnerable to high-energy waves. It is unusual as it has formed parallel to the coastline. Xwanage arch is gradually being worn away by mechanical, chemical and biological weathering. Groynes Groynes geofraphy wooden or stone barries which are built at right angles to the coast.

An Examination of the coast line in the Swanage Area.

This caused the formation of Old Harry, a stack. They reflect waves back out to sea preventing erosion of the cliff.

However, this creates a strong backwash which removes sediment from the beach and can lead to erosion under the wall. Concrete sea walls are in place along most of Swanage beach.

Behind the spit there is The Fleet, a lagoon. How do climate and geolgy influence geomorphic processes? Chesil Beach is an example of a bar. This is made of chalk which is a harder rock. 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. 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.

Behind the limestone is a layer of clay which is softer so more easily eroded. 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. 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. The Foreland, Old Harry and his Wife: As areas of the Dorset coast are being eroded, properities and infrastructure are at risk.

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. Sediment has been deposited over time to form a spit.
