The sands of time.

Some people said building the outer harbour at Yarmouth would increase erosion further down the coast,others say its a seasonal thing but the beach at the Denes in Lowestoft seems to be losing sand.Much of the ruins of the old sea wall can be seen on this picture,normally most of it is covered by a good depth of sand and shingle.The beach is unusable because of concrete and steel debris,which is said to protect the newer sea wall but if this sand continues to be lost it must increase the risk of damage.The denes area flooded many years ago destroying the fishing village,presumably the possibility of the outer harbour increasing erosion was studied,or was it?.
