Thorpeness coastal analysis report July 2011

Plan Drawings

The report below was carried out following the completion of the Phase 1 works, to look at how coastal processes affect the beach at Thorpeness, and whether the beach recycling works carried out during Phase 1 had any detrimental impact on the Ness.

Cliff erosion July 2010

Heavy storms and unusual weather patterns through May and June 2010 gave the foreshore such a pounding that tonnes of material was swept out to sea, revealing a series of gabions (rock-filled wire baskets) that had been in place since 1976 to help protect the coastline. The weather also worsened erosion of a previously eroding unprotected cliff face to the north of the existing defences.

Immediate emergency action was taken to contain the damage and stop the rapid erosion and so help safeguard nearby homes. Contactors placed new gabions in front of the cliff where the main erosion took place although works to defend the cliff at its closest point to the properties were destroyed by severe weather

While there was a partial recovery in beach levels, the local community, Suffolk Coastal’s coast protection team, the Environment Agency and Natural England worked together to develop a lasting solution to this dramatic erosion.

It is thanks to the efforts of the local community in raising £72,000 that allowed the works to begin as there were no other sources of national funding available. Suffolk Coastal contributed £30,000 to the scheme.

A 'soft toe' construction built from large geo-textile bags filled with sand and shingle has been put in place in the first phase of the emergency protection works. Bag laying operations were completed in December 2010 and work to cover the bags with shingle dug from the Ness was finished in February 2011.
