what have erosion and rates of coastal retreat reached in this area?
148 m/year
4 of 7
what has also contributed to increased erosion rates?
rising sea levels in the Mediterranean
5 of 7
what rate is this erosion at?
1.2mm / year
6 of 7

cus deeper water produces larger waves that carry higher amounts of energy and these can reach further inland.
