Case Study - The Holderness Coast

• The Holderness Coast is next to the city of Hull in the North-east of England. Its coast retreats by 1-2 metres every year
• At the holderness coast, strong prevailing winds have created destructive waves.
• The prevailing winds at holderness have also caused eroded material to move away from the place it has been eroded, exposing more soft rock
• The Holderness Coast is made up of boulder clay, which is easy to erode as it is soft. Heavy rainfall also causes mass movement of clay cliffs
• In 1991, a project invested 2 million into the Holderness coast to put rock armour and groynes into place
• The groynes in the holderness coast prevent sediment being carried away and for the beach to expand
• The rock armour in the holderness coasts absorbs some of the waves energy instead of the coast or cliffs doing this
• The coast at Holderness only eroded 1-2 metres each year compared to 7-8 metres before 1991
• Although, due to the scheme in Holderness, the south of Mappleton has experienced more coastal erosion. Less sediment is deposited at the Spurn point, which has caused dangers of being washed away
