SWANAGE CASE STUDY GCSE

This means waves are slowed, reducing erosion and will help to protect proprties and cliffs. 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. The spit has continued to join to the Isle of Portland. It is unusual as it has formed parallel to the coastline. Longshore drift affects the bay carrying material mainly gravel from the south to the north of the beach. As areas of the Dorset coast are being eroded, properities and infrastructure are at risk. Because there’s no erosion, there is no material to replenish the beach meaning the beach level will become lower.

The Foreland, Old Harry and his Wife: 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. 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. Chesil Beach is an example of a bar. Coastlines where the geology alternates between bands of hard and soft rock which are perpendicular to the shore are called discordant coastlines. Longshore drift affects the bay carrying material mainly gravel from the south to the north of the beach. The arch is gradually being worn away by mechanical, chemical and biological weathering.

Longshore drift affects the bay carrying material mainly gravel from the south to the north of the beach. The entrance to the cove is narrow where the waves have cut through weaknesses in the resistant limestone. The spit has continued to join to the Isle of Portland. Groynes Groynes are wooden or stone barries which are built at right angles to the coast.

Over time Old Harry will collapse to form a stump. The headland juts out into the sea, so it is more vulnerable to sanage waves. The area around Swanage is made up of bands of hard and soft rock.

This means waves are slowed, reducing erosion and will help to protect gsce and cliffs. However, this creates a strong backwash which sttudy sediment from the beach and can lead to erosion under the wall. The soft rock is made of clay and sands, and the hard rock is chalk and limestone. How are geomorphic processes creating coastal landforms? New timber groynes were installed on Swanage beach in and have reduced the loss of beach material.

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 stud. The arch is gradually being worn away by mechanical, chemical and biological weathering. The Foreland, Old Harry and his Wife: In the wintersand and shingle gfse dredged from the sea bed at Poole Harbour and added to the upper parts of Swanage beach creating a wider beach.

Lulworth Cove is situated on the south coast of England, on a concordant coastline. Concrete sea walls are in place along most of Swanage beach. Biological weathering gse by the vegetation on the top of the headland is also breaking up the rock. The alternating bands of hard and soft rock run parallel to the coast.

Towards the northern end of the bay the cliffs are covered in vegetation, stablising them and protecting them from erosion. Sea wall Concrete sea gcze are in place along most of Swanage beach.

There is also a risk for people from landslides and rockfalls. Then the cove widens where the softer clays have been more easily eroded.

Dorset is located in the south of England. It is called the Jurassic Coast as it has lots of fossils dating back to the Jurassic period.

They trap material being transported by longshore drift to create larger beaches which can then absorb wave energy to reduce erosion rates. Dorsert is located on the southern coast of the UK. This is made of chalk which is a harder rock. Because there’s no erosion, there is wtudy material to replenish the beach meaning the beach level will gcss lower. It connects the Isle of Portland to the mainland.

An Examination of the coast line in the Swanage Area.

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. Chemical weathering and erosion are gradually wearing down these down. Chesil Beach is an example of a bar. Sediment has been deposited over time to form a spit. Behind the spit there is The Fleet, a lagoon.
