There is also a risk for people from landslides and rockfalls. 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. Sea wall 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. It connects the Isle of Portland to the mainland. New timber groynes were installed on Swanage beach in and have reduced the loss of beach material.

Chesil Beach is an example of a bar. 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. It has been created by longshore drift. The spit has continued to join to the Isle of Portland. Dorsert is located on the southern coast of the UK. New timber groynes were installed on Swanage beach in and have reduced the loss of beach material.

But, by stopping the movement of beach material along the coast beaches further down the coast are becoming narrower and subject to geigraphy erosion due to reduced ability to absorb wave energy. There is also a risk for people from landslides and rockfalls.

Coastal Case Studies

The spit has continued to join to the Isle of Portland. Groynes Groynes are wooden or stone barries which are built at right angles swanabe the coast.

However, this creates a ycse backwash which removes sediment from the beach and can lead to erosion under the wall. Chemical weathering and erosion are gradually wearing down these down. Over time Old Harry will collapse to form a stump.

Dorset – case study of a UK coastal landscape

At the back of the cove is a band of more resistant chalk, so erosion is slower here. 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 studt to reduce erosion rates. Dorset is located in the south of England. Awanage arch is gradually being worn away by mechanical, chemical and biological weathering.

Erosion is the dominant process in the bay with the beach losing material year on year.

Longshore drift affects the bay carrying material mainly gravel from the south to the north of the beach. Then the sstudy widens where the softer clays have been more easily eroded.

The headland is made out of chalk, a hard rock. How are geomorphic processes creating coastal landforms? It has been created by longshore drift. This means waves are slowed, reducing erosion and will help to protect proprties and cliffs.

The soft rock is made of clay and sands, and the hard rock is chalk and limestone. Swsnage areas where the soft rock has eroded away, next to the headland, are called bays.

Elsewhere, the cliffs are not covered by vegetation, so wet weather weakens them causing slumps. The headland juts out into the sea, so it is more vulnerable to high-energy waves. Chesil Beach is an example of a bar. This is made of chalk which is a harder rock. They reflect waves back out to sea preventing erosion of the cliff. 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.

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. Sea wall Concrete sea walls are in place along most of Swanage beach. The entrance to the cove is narrow where the waves have cut through weaknesses in the resistant limestone.

Erosion by waves opened up a crack in the headland, which then became a cave and eventually an arch. How is human activity, including mangement, working in combination with geomorphic processes to shape the landscape?

Groynes are wooden or stone barries which are built at right angles to the coast. In the winterbzy and shingle were dredged from the sea bed at Poole Harbour and added to the upper parts of Swanage beach creating a wider beach. New timber groynes were installed on Swanage beach in and have reduced the loss of beach material.

Behind the limestone is a layer of clay which is softer so more easily eroded.

Dorsert is located on the southern coast of the UK.
