There is also a risk for people from landslides and rockfalls. 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. This caused the formation of Old Harry, a stack. The arch is gradually being worn away by mechanical, chemical and biological weathering. Coastlines where the geology alternates between bands of hard and soft rock which are perpendicular to the shore are called discordant coastlines.

The alternating bands of hard and soft rock run parallel to the coast. They trap material being transported by longshore drift to create larger beaches which can then absorb wave energy to reduce erosion rates. New timber groynes were installed on Swanage beach in and have reduced the loss of beach material. The headland juts out into the sea, so it is more vulnerable to high-energy waves. Sea wall Concrete sea walls are in place along most of Swanage beach. This means waves are slowed, reducing erosion and will help to protect proprties and cliffs. The limestone cliffs forming the back wall of the cove are vulnerable to mass movement and sometimes experience small slides and slumps.

How are geomorphic processes creating coastal landforms?

The gsce is gradually being worn away by mechanical, chemical and biological weathering. It is unusual as it has formed parallel to the coastline.

An Examination of the coast line in the Swanage Area.

Towards the northern end of geographg bay the cliffs are covered in vegetation, stablising them and protecting them from erosion. How do climate and geolgy influence geomorphic processes? The soft rock is made of clay and sands, and the hard rock is chalk and limestone.

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. The areas where the soft rock has eroded away, tsudy to the headland, are called bays. 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.

The limestone cliffs forming the back wall of the cove are vulnerable to mass movement and sometimes experience small slides and slumps. Geigraphy means waves are slowed, reducing erosion and will help to protect proprties and cliffs. Its coastline has examples of many erosional and depositional landforms. Sea wall Concrete sea walls are in place along most of Swanage beach.

The spit has continued to join to the Isle of Portland. They trap material being transported by longshore drift to create larger beaches which can then absorb wave energy to reduce erosion rates.

At the back of the cove is a band of more resistant chalk, so erosion is slower here. It connects the Isle of Portland to the mainland.

Dorset – case study of a UK coastal landscape

The area around Swanage is made up of bands of hard and soft rock. Chesil Beach is an example of a bar.

It is called the Jurassic Coast as it has lots of fossils dating back to the Jurassic period. Erosion is the dominant process in the bay with the beach losing material year on year. They reflect waves back out to sea preventing erosion of the cliff. sthdy

Coastal landforms – AQA – Revision 3 – GCSE Geography – BBC Bitesize

Concrete sea walls are in place along most of Swanage beach. Lulworth Cove is situated on the south coast of England, on a concordant coastline. Because there’s no erosion, there is no material to replenish the beach meaning the beach level will become lower.

As areas of the Dorset coast are being eroded, properities and infrastructure are at risk. Groynes are wooden or stone barries which are built at right angles to the coast. It has been created by longshore drift. New timber groynes were installed on Swanage beach in and have reduced the loss of beach material. Dorset is located in the south of England. Erosion by waves opened up a crack in the headland, which then became a cave and eventually an arch.

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. There is also a risk for people from landslides and rockfalls. Biological weathering caused by the vegetation on the top of the headland is also breaking up the rock. 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.
