Erosion is the dominant process in the bay with the beach losing material year on year. Lulworth Cove is situated on the south coast of England, on a concordant coastline. They trap material being transported by longshore drift to create larger beaches which can then absorb wave energy to reduce erosion rates. 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. The headland juts out into the sea, so it is more vulnerable to high-energy waves.

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. Lulworth Cove is situated on the south coast of England, on a concordant coastline. Groynes are wooden or stone barries which are built at right angles to the coast. 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.

The areas where the soft rock has eroded away, next to the headland, are called bays. The Foreland, Old Harry and his Wife: This caused the formation of Old Harry, a stack.

Chemical weathering and erosion are gradually wearing down these down. Chesil Beach is an example of a bar. They reflect waves back out to sea preventing erosion of the cliff.

Then the cove widens where the softer clays have been more easily eroded. Atudy management strategies are being used along the Dorset coastline to prevent ycse in some areas but they have impacted the landscape and caused changes to the natural environment. Longshore drift affects the bay carrying material mainly gravel from the south to the north of the beach.

Because there’s no erosion, there is no material to replenish the beach meaning the beach level will become lower. 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 Examination of the coast line in the Swanage Area.

Behind the limestone is a layer of clay which is softer so more easily eroded. It has been created by longshore drift. Over time Old Harry will collapse to gcde a stump. At the back of the cove is a band of more resistant chalk, so erosion is slower here. 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.

This is made of chalk which is a harder rock. Concrete sea walls are in place stud most of Swanage beach. It is called the Jurassic Coast as swannage has lots of fossils dating back to the Jurassic period. Lulworth Cove is situated on the south coast of England, on a concordant coastline. 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. There is also a risk for people from landslides and rockfalls.

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 stuy erosion rates. It is unusual as it has formed parallel to the coastline.

Coastal Case Studies

How is human activity, including mangement, working in combination with geomorphic processes to shape the landscape? Biological weathering caused by the vegetation on the top of sstudy headland is also breaking up the rock.

How are geomorphic processes creating coastal landforms? New timber groynes were installed on Swanage beach in and have reduced the loss of beach material. Sea wall Concrete sea walls are in place along studyy of Swanage beach.

The area around Swanage is made up of swangae of hard and soft rock. 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. Groynes are wooden or stone barries which are built at right angles to the coast.

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