This can create beaches to dissipate, rendering them pointless for coastline goers. Normally, seawalls can be a successful way to manage seaside erosion, yet just if they are built well and out of materials that can withstand the force of ongoing wave energy. Some understanding is required of the coastal procedures and morphodynamics particular to the seawall location.

Water pressure accumulation is triggered when groundwater is not drained pipes from behind the seawall. Groundwater against a seawall can be from the location's all-natural water-table, rainfall percolating into the ground behind the wall surface and waves overtopping the wall.
