Holderness – A case study of cause, effect and response

Coastal management at Hornsea and Withernsea are examples of hard engineering solutions to coastal erosion. Sea level rise associated with climate change and the prevailing north-easterly wind conspire stduy make this coast susceptible to rapid rates of coastal erosion. As the movement of sediment has been disrupted due to the construction of the stone groynes material previously feeding the beaches to the south of the Mappleton is restricted.

The Holderness Coast is one of Europe’s fastest eroding coastlines. Mappleton is an excellent case study of an attempt at coastal management.

Erosion on the Holderness Coast

Over time the land will become marshland and new habitats will occur.

The Holderness Coast is located on the east coast of England. The coastline consists of low glacial clkff boulder clay. Tidal range at the Holcerness coast is very high and can reach up to 7 m.

Spurn Point provides evidence of longshore drift on the Holderness Coast. Published by Crystal Blake Modified over 3 years ago. As the result of this the beaches to the south have very little sediment and during low tide expose a combination of sand and clay boulders that have been eroded from the cliffs.

Rock armour are large boulders that are built up along the coast. This is around 2 million tonnes of material every year. For a named coast either hard or soft rockdescribe its main features. We think you have liked this presentation.

Holderness coast erosion sstudy Impacts on people: This is one of the most vulnerable coastlines in the world and it retreats at a rate of one to two metres every year.

An annotated photograph to show the coastal management techniques used the protect Mappleton and their impact click to enlarge. This means that even at high tide waves do not reach the base of the cliffs along the seafront at Mappleton and the erosion has slowed to a point where it is no longer a threat to the settlement.

There are two main reasons why this area of coast is eroding so rapidly.

Hurricane Katrina Case Study. This is evident in the image below.

In order to protect the cliffs along the front of Mappleton from undercutting, their gradient was also reduced artificially. It will therefore erode quickly, especially when saturated. It is this soft boulder clay that is being rapidly eroded. To make this website work, we log user data and share it with processors.
