Geography Coasts Case Studies

HideShow resource information

Holderness Coastline- the cause and consequence of the cliff collapse on people living along this coastline. 

Located in East Yorkshire. One of the fastest eroding coastlines in europe. Average rate of erosion 1.8m per year. the coastline is 61 km long. stretches from flamborough head to spurn head. Erosion is causing the cliff to collapse along the coastline. The material then gets washed away so the coastline retreats. 

Reasons for rapid erosion: 

Easily eroded rock type-  cliffs are mostly made of boulder clay which is easily eroded. it is likely to slump when it is wet causing cliff collapse. 

The beach is naturally narrow- beaches slow waves down reducing their erosive power. Narrow beaches give less protection. 

People are worsening the situation- coastal defences like groynes have been built in mappleton. Groynes stop material from being moved further
