8th February: Chesil Cove - wave height is controlled by wind speed, the length of time the wind is blowing and the fetch (distance over which the wind blows, theoretically this can be all the way from South America)

Impact of storms

beach crest recession varied from 4 to 16 metres, average 10 metres
crest lowering up to 2 metres
3.5 metres lowering of beach in Chesil Cove
150,000 cubic metres of shingle moved off-shore

Management of the problems

protection for the undermined sea wall
mending the gabion tower and terrace
shingle management
road closures occurred cutting off Portland
repairing the undermined sea wall
rock-armour (Portland Limestone) had been brought in to protect the sea wall while it was reinforced
18th March: piling completed and concrete poured
shingle had gone over the crest of the beach and minor flooding had occurred. The Cove Inn also suffered
moving boulders/rock armour to protect southern end of the esplanade. End of April, completed protection for the undermined sea wall and some return of shingle
It was decided to rebuild the gabion tower rather than mend it. View of the tower in May
6th May: excavation to base of gabion tower and renewing the gabion mattresses mid-May
rebuilding the gabion tower in June and still in progress early August
Cost of remedial work?

Chesil Cove sea wall repair (WPBC asset) £285k
Chiswell gabion repairs (tower and mattresses) £758k
