Coastal management-Holderness Flashcards
What is being done to manage coastal erosion?
1) 2km long concrete sea wall built in Hornsea to deflect wave energy back into the ocean using a overhanging lip.
2) Local authorities in Mappleton have invested in rip-rap made of Norwegian granite along the foot of cliffs to absorb wave energy. This cost roughly $2 million.
3) The same has been done at Withernsea but smaller scale.
4) Revetments have been constructed in Easington along the narrow beach to prevent the gas terminal situated 20m inland from falling into the sea.
5) The government in in Hornsea has also resorted to beach nourishment, a method of soft engineering, to increase beach size so more wave energy can be absorbed.
6) Cliff drainage in Easington, a soft engineering solution, also helps reduce the rate at which cliffs get saturated and slump into the sea under pressure.
Introductory sentence
Along the Holderness coast, 2m of soft, unconsolidated boulder clay is eroded every year. This makes it Europe’s fastest retreating coastline.
