  1. Lesson 7: Holderness and Swanage Case Study Lesson Objective: To produce a detailed case study on an area of coastal management

  2. MAPLETON- HOLDERNESS • Mappleton is on the Holdeness coast and the cliffs are made of boulder clay and were eroding very quickly. The village was in danger, and several houses had been lost. However the B1242 road link was in danger and this made it economically viable to build sea defences. An offshore bar of granite was built at the cost of £ 2 million. This prevented erosion at Mappleton but prevented material moving southwards.

  3. GREAT COWDEN At Great Cowden erosion was less than 2m p.a. until the Mappleton defences were put in place . In two years, an acre of land has been lost, and the coast has eroded 80m.

  4. SUE EARL’S FARM • Sue Earle's farmhouse was knocked down in 1997 as it was at the cliff edge and was considered dangerous. It cost the Earle's £3000 for the privilege. They are now suing in court. • http://www.bing.com/images/search?q=sue+earls+farm+holderness&go=&form=QBIR&qs=n&sk=#focal=2923ba1a45e9a299f924ff8465d3cc22&furl=http%3A%2F%2Fwww.bbc.co.uk%2Flearningzone%2Fclips%2Fimages%2Fpreviews%2Fp_geog%2Fp_geog_ec_08369_16x9.jpg • http://www.bbc.co.uk/learningzone/clips/coastlines-drastic-erosion/8434.html

  5. Coastal Management Zone (ICZM) • Planners are trying to find sustainable ways of managing the coasts -to reduce the damage to the environment. • Planners are treating the whole of the coastal areas from the shore line to several kilometres inland (holistic approach) • Holderness area, Yorkshire is part of the EAST RIDING ICZM plan, introduced in 2002 • Set out to protect some areas form erosion and other areas ‘do nothing’ approach taken • Local people were not happy, they argued the local social and economic needs were being ignored

  6. Using the maps- locate Swanage Bay Geographically. Where is Swanage?

  7. What are the options? • In the UK, local councils pay for sea defences. Some may get money from the Government or Environment Agency if there is a flood risk. There are 4 choices councils can make: • Hold the line use sea defences to stop erosion EXPENSIVE • Advance the line use sea defences to move the coast further into the sea VERY EXPENSIVE • Strategic Retreat gradually let the coast erode and move people away from risks. This may involve compensation for some people • Do nothing let nature take its course. • These choices can cause conflicts. Choices 3 and 4 will see people loose land, homes and businesses. One stretch of coastline may involve several choices.

  8. Case Study, Swanage Bay and Durlston Bay • Make notes under each heading using the information from page 82-83 Evolving Planet. You may need to think independently about some of the answers • Location • Problems in Durlston Bay • Solutions in Durlston Bay (include an annotated sketch) • Problems in Swanage Bay • Solutions in Swanage Bay (include an annotated sketch) economic Social Political Environmental

  9. Is Swanage sustainable?
