GCSE GEOGRAPHY SWANAGE BAY CASE STUDY

It has been created by longshore drift. The limestone cliffs forming the back wall of the cove are vulnerable to mass movement and sometimes experience small slides and slumps. Over time Old Harry will collapse to form a stump. Towards the northern end of the bay the cliffs are covered in vegetation, stablising them and protecting them from erosion. How do climate and geolgy influence geomorphic processes?

Chesil Beach is an example of a bar. Groynes are wooden or stone barries which are built at right angles to the coast. Coastlines where the geology alternates between bands of hard and soft rock which are perpendicular to the shore are called discordant coastlines. Towards the northern end of the bay the cliffs are covered in vegetation, stablising them and protecting them from erosion. The headland juts out into the sea, so it is more vulnerable to high-energy waves.

The limestone cliffs forming the back wall of the cove are vulnerable to mass movement and sometimes experience small slides and slumps. Dorset is located in the south of England. This is made of chalk which is a harder rock.

An Examination of the coast line in the Swanage Area.

The Foreland, Old Harry and his Wife: The headland is made out of chalk, a hard rock. It is called the Jurassic Coast as it has lots of fossils dating back to the Jurassic period. It has been created by longshore drift.

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 and eventually an arch. Sediment has been deposited over time to form a spit. The bands of cawe 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.

This caused the formation of Old Harry, a stack. Chesil Beach is an example of a bar.

Then the cove widens where the softer clays have been more easily eroded. Behind the spit there is The Fleet, a lagoon. Coastlines where the geology alternates between bands of hard and baay rock which are swamage to the shore are called discordant coastlines. But, by stopping the movement of beach material along the coast beaches further down the coast are becoming narrower and subject to more erosion due to reduced ability to absorb wave energy.

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

How are geomorphic processes creating coastal landforms? Its coastline has examples of many erosional and depositional landforms.

Dorset – case study of a UK coastal landscape

How do climate and geolgy influence geomorphic processes? The entrance to the cove is narrow where the waves have cut through weaknesses in the resistant limestone. This means waves are slowed, reducing erosion and will help to protect proprties and cliffs.

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.

A concordant coastline has the same type of rock cas its length. Lulworth Cove is situated on the south coast of England, on a concordant coastline. The areas where the soft rock has eroded away, next to the headland, are called bays. Biological weathering caused by the vegetation on the top of the headland is also breaking up the rock. It connects the Isle of Portland to the mainland. There is also a risk for people from landslides and rockfalls. Sea wall Concrete sea walls are in place along most of Swanage beach.

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. How is human activity, including gccse, working in combination with geomorphic processes to shape the landscape?

They trap material being transported by longshore drift to create larger beaches which can then absorb wave energy to reduce erosion rates. 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.
