This can cause beaches to dissipate, rendering them useless for coastline goers. Usually, seawalls can be a successful method to control coastal disintegration, however only if they are created well and out of materials that can endure the pressure of ongoing wave energy. Some understanding is required of the seaside procedures and morphodynamics particular to the seawall place.

Superstorm Sandy sent out a tornado rise of 45 m onto New Jacket's and New york city's barrier island and urban shorelines, estimated at $70 billion in damage.
