The report says: "The storms in December 2013 and January 2014 caused additional erosion of approximately 4,000 cubic metres to the existing SSSI, and reduced the crest width
to less than 5m from the sea wall in places.
Measurements of maximum length, longitudinal length, proximal width, distal width, delto-pectoral crest width
, lateral diameter at sectioning site, ventral to dorsal thickness at sectioning site, and mass were recorded.
Around 3,955 tonnes of rock was placed under the shingle to maintain the crest width
during future storms, said Neil Watson for the Environment Agency.
