Coastal defences, Collywell Bay
-
Description
"See another photo for a brief discussion of the geology: [[5617508]] There is a good disscussion about erosion of this coastline, including the measures taken to protect the cliff face below the houses on Collywell Bay Road, in Chapter 8, 'Changing Coastal Environments' in Changing Environments by Susan Bermingham (2000). The most recent sea defences comprising large concrete slabs attached to the cliff face at the northern end of the bay were completed in 1981. The older, cliff-base, defenses in the foreground have brought about an accelerated rate of sand removal from the natural protection afforded by the beach of Collywell Sands which used to extend below the cliffs. Undercutting of the defenses is now taking place as a result of increased wave energy. The movement west of the mean high water mark is clearly demonstrated by comparison of old maps."
