GCSE GEOGRAPHY SWANAGE BAY CASE STUDY

Chemical weathering and erosion are gradually wearing down these down. Chesil Beach is an example of a bar. 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. Sea wall Concrete sea walls are in place along most of Swanage 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. Groynes are wooden or stone barries which are built at right angles to the coast.

Chemical weathering and erosion are gradually wearing down these down. The areas where the soft rock has eroded away, next to the headland, are called bays. Dorset is located in the south of England. Lulworth Cove is situated on the south coast of England, on a concordant coastline. Then the cove widens where the softer clays have been more easily eroded. 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. Chesil Beach is an example of a bar.

There is also a risk for people from landslides and rockfalls. The headland juts out into the sea, so it is more gsce to high-energy waves.

The areas where the soft rock has eroded away, next to the headland, are swannage bays. They reflect waves back out to sea preventing erosion of the cliff. Longshore drift affects the bay carrying material mainly gravel from the south to the north of the beach. Groynes are wooden or stone barries which are built at right angles to the coast.

Coastal Case Studies

Because there’s no erosion, there is no material to replenish the beach meaning the beach swannage will become lower. The spit has continued to join to the Isle of Portland. However, this creates a strong backwash which removes sediment from the beach and can lead to erosion under the wall.

The area around Swanage is made up of bands of hard and soft rock. Erosion by waves opened up a crack in the headland, which then became a cave and eventually an arch. Biological weathering caused by the vegetation on the top of the headland is also breaking up the hay.

Erosion is the dominant process in the bay with the beach losing material year on year. 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. New timber groynes were installed on Swanage beach in and have reduced the loss of beach material.

Sea wall Concrete sea walls are in place along most of Swanage beach. Towards the northern end of the bay the cliffs are covered in vegetation, stablising them and protecting them from erosion. 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. It connects the Isle of Portland to the mainland. Beach replenishment In the wintersand and shingle were dredged from the sea bed at Poole Harbour and added gcwe the upper parts of Swanage beach creating a wider beach.

They trap material being transported by longshore drift to create larger beaches which can then absorb wave energy to reduce erosion rates. The Foreland, Old Harry and his Wife: Chesil Beach is an example of a bar.

Elsewhere, the cliffs are not covered by vegetation, so wet weather weakens them causing slumps. Its coastline has examples of many erosional and depositional landforms.

The soft rock is made of clay and sands, and gcee hard rock is chalk and limestone. Sediment has been deposited over time to form a spit.

How is human activity, including mangement, working in combination with geomorphic processes to shape the landscape? Over time Old Harry will collapse to form a stump. 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. It is unusual as it has formed parallel to the coastline. In the wintersand and shingle were dredged from stud 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? Chemical weathering and erosion are gradually wearing down these down. This caused the formation of Old Harry, a stack. The alternating bands of hard and soft rock run parallel to the coast.
