This means waves are slowed, reducing erosion and will help to protect proprties and cliffs. Because there’s no erosion, there is no material to replenish the beach meaning the beach level will become lower. 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. Its coastline has examples of many erosional and depositional landforms.
It has been created by longshore drift. 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. The entrance to the cove is narrow where the waves have cut through weaknesses in the resistant limestone. Elsewhere, the cliffs are not covered by vegetation, so wet weather weakens them causing slumps. It is called the Jurassic Coast as it has lots of fossils dating back to the Jurassic period. It is unusual as it has formed parallel to the coastline.
This means waves are slowed, reducing erosion and will help to protect proprties and cliffs. It connects the Isle of Portland to the mainland.
Dorset is located in the south of England.

They reflect waves back out to sea preventing erosion of the cliff. Sediment has been deposited over time to form a spit. They trap material being transported by longshore drift to create larger beaches which can then absorb wave energy to reduce erosion rates.
The alternating bands of hard and soft rock run parallel to the coast. How do climate and geolgy influence geomorphic processes? Its coastline has examples of many erosional and depositional landforms. However, this creates a strong backwash which removes sediment from the beach and can lead to erosion under the wall.
The Foreland, Old Harry and his Wife: The spit has continued to join to the Isle of Portland. The headland is made out of chalk, a hard rock. Chesil Beach is an example of a bar. There is also a risk for people from landslides and rockfalls. It is called the Jurassic Coast as it has lots of fossils dating back to the Jurassic period.

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. Behind the spit there is The Fleet, a lagoon. Sea wall Concrete sea walls are in place along most of Swanage beach. The area around Swanage is made up of bands of hard and soft rock.
Erosion is the dominant process in the bay with the beach losing material year on year. Towards the northern end of the bay the stydy are covered in vegetation, stablising them and protecting them from erosion.
The bands of soft rock erode more quickly than those swanahe the more resistant hard rock leaving a section of land jutting out into the sea, called a headland.
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.
Concrete sea walls are in place along most of Swanage beach. Then the cove widens where the softer clays have been more easily eroded.

Groynes are wooden or stone barries which are built at right angles to the coast. This caused the formation of Old Harry, a stack. A concordant coastline has the same type of rock along its length.
New timber groynes were installed on Swanage beach in and have reduced the loss of beach material. As areas of the Dorset coast are being eroded, properities and infrastructure are at risk.
An Examination of the coast line in the Swanage Area.
Longshore drift affects the bay carrying material mainly gravel from the south to the stdy of the beach. How are geomorphic processes creating coastal landforms? Coastal management strategies are being used along the Wsanage coastline to prevent erosion in some areas but they have impacted the landscape and caused changes to the natural environment.
The arch is gradually being worn away by mechanical, chemical and biological weathering. Behind the limestone is a layer of clay which is softer so more easily eroded. Elsewhere, the cliffs are not covered by vegetation, so wet weather weakens them causing slumps.
