Coastal Management - Case Study
Fichas del conjunto (10)
- 1Location:Holderness - East Yorkshire
- 2How much erosion is there each year along Holderness coast?1.8m
- 3How much farmland is lost each year?80 000m squared
- 4How many km of Holderness coastline has been protected?11.4km
- 5How is Bridlington protected?Wooden groynes and 4.7km of sea wall
- 6Where were two rock groynes built in 1991? How much did they cost and what do they protect?Mappleton - £2 million - to protect the vilage and a coastal road from erosion and flooding.
- 7What defences were put up at Withernsea? What happened to one of the defences?Groynes to create wider beaches, sea wall - the wall was damaged in severe storms in 1992 so rip raps were placed in front of it.
- 8What problems did groynes cause? What is at risk?They protect local areas but cause narrow beaches further down the Holderness coast which increases erosion. E.g Cowden Farm is at risk of falling into the sea.
- 9How are bays being formed?They are forming between the protected areas and the protected areas are becoming headlands which are eroding more easily. Maintaining defences is expensive.
- 10Material produced from the erosion of Holderness is normally transported south into the Humber Estuary and down Lincolnshire coast. What problems have been caused by reducing the amount of material eroded?It increases the risk of flooding in the Humber Estuary because there is less material to slow the floodwater down.
