- Walton-on-the-Naze
- Facts
- Coastal town in Essex
- Walton can be split into two areas
- Northern area: not protected b/c the Environment Agency does not consider the buildings worth saving
- Southern part: protected because of the coastal town of Walton with its population of 12,000
- Problem
- Suffers from coastal erosion due to the types of rock which make up the cliff
- Red Crag
- Both are easily eroded by the sea
- London Clay
- Both are easily eroded by the sea
- Slumping makes the defense of the area even more complex
- Longshore drift moves sand along the coastline from south to north
- Red Crag
- Suffers from coastal erosion due to the types of rock which make up the cliff
- Management
- 1977 - Major project completed on the southern part of the coastline
- Groynes would help to stop longshore drift and keep the beach in place
- Breakwaters, which are large groynes, were placed at regular intervals b/c of the power of longshore drift
- The cliff was regraded to produce a gentler slope
- Planted with a variety of shrubs and trees to stop people scrambling
- Drainage channels installed to allow water to flow underground through special tunnels and out onto the beach through holes in the seawall
- At the bottom of the cliff there is a sea wall to protect the London clay which is very easily eroded by the sea
- 1998 - The council paid £167,000 for 300 tonnes of Leicester granite to be placed around the Tower breakwater
- The rip-rap has slowed down the erosion in this area but has not stopped it
- 1999 - Beach in front of the cliffs at the northern part was replenished with sand and gravel
- The majority of this material has been removed by 2003 illustrating the power of longshore drift
- 1977 - Major project completed on the southern part of the coastline
