This can create coastlines to dissipate, making them ineffective for coastline goers. Typically, seawalls can be a successful way to regulate seaside erosion, however only if they are created well and out of materials that can withstand the force of ongoing wave energy.

Superstorm Sandy sent a storm surge of 45 m onto New Jersey's and New York's barrier island and city coastlines, approximated at $70 billion in damage. This trouble can be gotten over by more modeling and establishing the extension of height and reinforcement of current seawalls which requires to occur for safety to be made sure in both scenarios.
