This can create coastlines to dissipate, providing them pointless for beach goers. Typically, seawalls can be a successful way to manage seaside disintegration, but only if they are constructed well and out of materials that can stand up to the pressure of ongoing wave power.

Superstorm Sandy sent out a tornado surge of 45 m onto New Jacket's and New York's barrier island and metropolitan shorelines, estimated at $70 billion in damages. This problem might be gotten over by further modeling and identifying the expansion of height and support of present seawalls which needs to occur for safety and security to be made sure in both situations.
