Today the Isle is an island no longer and the erstwhile channel is now flat marshland criss-crossed by drainage ditches. Meanwhile, the exposed chalk cliffs are gradually being worn down by the sea, particularly at the North Foreland. Much else of the coast is a built-up area. The Wantsum area is still liable to flooding: during the North Sea flood of 1953 Thanet was cut off for a few days, but the sea defences have been strengthened since then.
