The Holderness Coast (Coasts Case Study) | AQA GCSE 9-1 Geography

Where is the Holderness Coast? What defences are found along the coastline? What is the coastal management at Mappleton? This is the forty-second video for the AQA GCSE 9-1 Geography course, and the ninth video of the Physical Landscapes topic.

It is located in Yorkshire in the North of England, running between Flamborough Head in the north and the Humber Estuary in the south. Flamborough Head is home to dramatic chalk cliffs and erosional landforms including arches, stacks and wave-cut platforms. The rest of the coastline is made up of soft boulder clay, leading to the formation of many beaches. A spit can also be found at the mouth of the Humber, known as Spurn Point. The soft rock makes the Holderness Coast one of the fastest eroding coastlines in Europe. This poses a significant threat to settlements along the coast, including the towns of Bridlington, Hornsea and Withernsea. The main road along the coastline runs very close to the cliffs through the village of Mappleton and a gas terminal is found at Easington in the south. Coastal management is needed to prevent these places from joining dozens of other villages that have been lost to the sea. So what has been done? The importance of the road through Mappleton led to the construction of rock groynes and rock armour at Mappleton in 1991, at a cost of £2 million. The groynes catch sediment from longshore drift, which has caused a significant beach to build up. This acts as a buffer between the sea and the cliffs, which is further enhanced by the rock armour, which absorbs wave energy. This has successfully protected the village and the main B1242 road and the larger beach is now popular with tourists. However, the rate of erosion has increased massively south of defences due to the groynes starving these beaches of sand. This is very noticeable on satellite imagery - where you can see the cliff is significantly further back after the defences. This has created conflict with local farmers as well as the Golden Sands Holiday Park at Great Cowden. Bridlington is home to a 3.6km sea wall and many groynes, resulting in the build-up of a very large beach. The sea wall is curved, reflecting wave energy back towards the sea, and also has a promenade on top. The promenade and wide beaches make Bridlington a popular tourist resort. Similar defences are also found at Hornsea and Withernsea and the gas terminal at Easington is protected by rock armour which was implemented at a cost of £6.6 million in 1999. -- GCSE Geography 13/05/2023 Keducate
