SWANAGE CASE STUDY GCSE

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. How is human activity, including mangement, working in combination with geomorphic processes to shape the landscape? However, this creates a strong backwash which removes sediment from the beach and can lead to erosion under the wall. Groynes Groynes are wooden or stone barries which are built at right angles to the coast. Sea wall Concrete sea walls are in place along most of Swanage beach.

Concrete sea walls are in place along most of Swanage beach. Because there’s no erosion, there is no material to replenish the beach meaning the beach level will become lower. Groynes are wooden or stone barries which are built at right angles to the coast. Elsewhere, the cliffs are not covered by vegetation, so wet weather weakens them causing slumps. This caused the formation of Old Harry, a stack.

Its coastline has examples of many erosional and depositional landforms.

Chesil Beach is an example of a bar. 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. It swamage the Isle of Portland to the mainland.

How is human activity, including mangement, working in combination gxse geomorphic processes to shape the landscape? The arch is gradually being worn away by mechanical, chemical and biological weathering.

How do climate and geolgy influence geomorphic processes? Over time Old Harry will collapse to form a stump.

As areas of the Dorset coast are being eroded, properities and infrastructure are at risk. It is called the Jurassic Coast as it has lots of fossils dating back to the Jurassic period. They trap material swanag transported by longshore drift to create larger beaches which can then absorb wave energy to reduce erosion rates.

They reflect waves back out to sea preventing erosion of the cliff. Sediment has been deposited over time to form a spit. Behind the spit there is The Fleet, a lagoon. 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.

Groynes Groynes are wooden or stone barries which are built at right angles to the coast. It is unusual as it has formed parallel to the coastline. This means waves are slowed, reducing atudy and will help to protect proprties and cliffs. Chemical weathering and erosion are gradually wearing down these down. Concrete sea walls are in place along most of Swanage beach. The headland juts out into the sea, so it is more vulnerable to high-energy waves. Elsewhere, the cliffs are not covered by vegetation, so wet weather weakens them causing slumps.

The area around Swanage is made up of bands of hard and soft rock. There is also a risk for people from landslides and rockfalls. Coastlines where the geology alternates between bands of hard and soft rock which are perpendicular to the shore are called discordant coastlines.

It has been created by longshore drift.

Dorset – case study of a UK coastal landscape

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 cass walls are in place along most of Swanage beach. Behind the limestone is a layer of clay which is softer so more easily eroded.

The soft rock is made of clay and sands, and the hard rock is chalk and limestone. 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.

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. At the back of the cove is a band of more resistant chalk, so erosion is slower here.
