This can create beaches to dissipate, making them ineffective for coastline goers. Normally, seawalls can be a successful method to manage coastal erosion, but only if they are created well and out of products that can stand up to the force of ongoing wave energy.

Superstorm Sandy sent out a storm surge of 45 m onto New Jersey's and New york city's barrier island and urban shorelines, approximated at $70 billion in damage.

Water pressure accumulation is created when groundwater is not drained from behind the seawall. Groundwater versus a seawall can be from the area's all-natural water-table, rain percolating into the ground behind the wall surface and waves overtopping the wall.
