- This is a sediment cell located in the North East England, with a length of 90 kilometres running from Flamborough head in the north to spurn head in the South. Its closest city is whole located 15 miles to the West and the coastline faces the North Sea, thus receiving high energy waves . The coastline is one of the fastest retreating coastlines in Europe due to its geology. Is largely made up of boulder clay brought around during the last Ice Age, with the exception of the north of the coastline at Flamborough head, which is a protruding headland made out of chalk. The made form of mass movement is slumping, where precipitation percolates into the consolidated rock, increasing its weight and turning the clay composition into mud. This acts as a lubricant , which causes the rock to fall and be washed away by the sea.
- At Flamborough head, which is made out of chalk, has received destructive waves, which has led to wave cut platforms to form. These wave cut platforms are located within the sheltered area of the headland , creating low energy environments. This is because of wave refraction where wave energy becomes concentrated at the headland. The sheltered platforms have become beaches, thus becoming valuable land for the area of Bridlington, who have marketed the area as a luxury seaside resort, leading to economic benefits from the increased tourism.
- At Mappleton, a town located further down the coastline, have installed £2 million worth of groynes and rock armour. This was due to the direction of longshore drift taking place south, which meant sediment was moving south, thus Mappleton was at risk of losing their beaches. As a result, the hard engineering defences had been implemented to reduce the transportation of sediments down the beach. The town of Mappleton has benefited from this as wider beaches had led to increased levels of tourism and thus consequent economic benefits. However , the groynes had reduced the supply of sediments S, which meant that there was a negative sediment budget at Great Cowden, thus a decreasing beach. Since these are natural defences against a wave energy, that diminishing size of the beach is exposed behind cliff faces which has led to increased erosion rates of up to 9 metres a year making it the fastest retreating coastline in Europe.
- A similar strategy was implemented at Withernsea and like Mappleton has benefited with increased economic growth and a positive perception about the area. However at Easington, the lack of the supply of settlement has led to decreasing beaches an exposed cliff faces. The Easington gas terminal is only located 25 metres from the cliff edge , so the terminal had installed 1.56 kilometres worth of revetments . This had created an artificial headland, which led to wave refraction. As a benefit, this had created a sheltered environment for the SSSI adjacent to the terminal.
- As a result, of the revetments, this had reduced the supply of sediment to the simple spit at spurn head which covers a part of the Humber estuary. And an inadequate amount of sediment has led to a decrease in the size of despair , which is a risk of being washed away. As of present day, the local government have implemented they do nothing SMP as it’s deemed the land is not valuable. Although, there are signs of a salt marsh forming behind the spirit, which has led to protests against the SMP.
