SWANAGE CASE STUDY GCSE

Biological weathering caused by the vegetation on the top of the headland is also breaking up the rock. A concordant coastline has the same type of rock along its length. Towards the northern end of the bay the cliffs are covered in vegetation, stablising them and protecting them from erosion. Dorsert is located on the southern coast of the UK. The headland juts out into the sea, so it is more vulnerable to high-energy waves.

It has been created by longshore drift. Sea wall Concrete sea walls are in place along most of Swanage beach. 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. Then the cove widens where the softer clays have been more easily eroded. It connects the Isle of Portland to the mainland. How are geomorphic processes creating coastal landforms? Towards the northern end of the bay the cliffs are covered in vegetation, stablising them and protecting them from erosion.

New timber groynes were installed on Swanage beach in and have reduced the loss of beach material. The entrance to the cove is narrow where the waves have cut through weaknesses in the resistant limestone. Dorsert is located on the southern coast of cade UK. This means waves are slowed, reducing erosion and will help to protect proprties and cliffs. Towards the northern end of the bay the cliffs are covered in vegetation, stablising them and protecting them from erosion.

However, this creates a strong backwash which removes sediment from the beach and can lead to erosion under the wall. Groynes are wooden or stone barries which are built at right angles to the swanaye.

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. Erosion by waves opened up a crack in the headland, which then became a cave dtudy eventually an arch.

Behind the spit there is The Fleet, a lagoon. This is made of chalk dwanage is a harder rock. It is called the Jurassic Coast as it has lots of fossils dating back to the Jurassic period.

They reflect waves back out to sea preventing erosion of the cliff. It has been created by longshore drift. An arch at the end of the headland has collpased to swwanage a stack called Old Harry and a stump called Old Harry’s Wife.

They trap material being transported by longshore drift to create larger beaches which can then absorb wave energy to reduce erosion rates. The headland is made out of chalk, a hard rock. Chemical weathering caxe erosion are gradually wearing down these down.

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. 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.

Over time Old Harry will collapse to form a stump. The soft rock is made of clay and sands, and the hard rock is chalk and limestone. The Foreland, Old Harry and his Wife: It connects the Isle of Portland to the mainland.

Sea wall Concrete cass walls are in place along most of Swanage beach. As areas of the Dorset coast are being eroded, properities and infrastructure are at risk. 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.

Its coastline has examples of many erosional and depositional landforms. Coastlines where the geology alternates between bands of hard and soft rock which are perpendicular to the shore are called discordant coastlines. Erosion is the dominant process in the bay with the beach losing material year on year.

Coastal management strategies are ycse used along the Dorset coastline to prevent erosion in some areas but they have impacted the landscape and caused changes to the natural caxe.

Elsewhere, the cliffs are not covered by vegetation, so wet weather weakens them causing slumps.
