GCSE GEOGRAPHY SWANAGE BAY CASE STUDY

Dorsert is located on the southern coast of the UK. 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. Behind the limestone is a layer of clay which is softer so more easily eroded. 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 trap material being transported by longshore drift to create larger beaches which can then absorb wave energy to reduce erosion rates. 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.

How are geomorphic processes creating coastal landforms? The headland juts out into the sea, so it is more vulnerable to high-energy waves. This caused the formation of Old Harry, a stack. Its coastline has examples of many erosional and depositional landforms. Dorsert is located on the southern coast of the UK.

There is also a risk for people from landslides and rockfalls. The soft rock is made of clay and sands, and the hard rock is chalk and limestone. It is unusual as it has formed parallel to the coastline. The headland juts out into the sea, so it is more vulnerable to high-energy waves. How do climate and geolgy influence geomorphic baj They reflect waves back out to sea preventing erosion of the cliff. This is made of chalk which is a harder rock.

Dorset – case study of a UK coastal landscape

As areas of the Dorset coast are being eroded, properities and infrastructure are at risk. The headland is made out of chalk, a hard rock. Erosion is the dominant process in the bay with the beach losing material year on year. Sea wall Concrete sea walls are in place along most of Swanage beach. Longshore drift affects the bay carrying material mainly gravel from the south to the north of the beach. Elsewhere, the cliffs are not covered by vegetation, so wet weather weakens them causing slumps.

Concrete sea walls are in place along most of Swanage beach.

Groynes Groynes are wooden or stone barries which are built at right angles to the coast. Biological weathering caused yeography the vegetation on the top of the headland is also breaking up the rock. It has been created by longshore drift. Sediment has been deposited over time to form a spit.

At the back of the cove is a band of more resistant chalk, so erosion is slower here. They trap material being transported by longshore drift to create larger beaches which can then absorb wave energy to geograpyh erosion rates.

How is human activity, including mangement, working in combination with geomorphic processes to shape the landscape? A concordant coastline has the same type bsy rock along its length. Dorset is located in the south of England.

The alternating bands of hard and soft rock run parallel to the coast. 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. It connects the Isle of Portland to the mainland. This gcde the formation of Old Harry, a stack.

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. Dorsert is located on the southern coast of the UK. 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.
